ADAPTIVE HEADLIGHT SYSTEM

Adaptive Headlight System :-

Suppose you are driving home from a weekend vacation. It's late at night, and the winding two-lane road has no streetlights. You approach a curve at 40 mph -- slow enough to make the turn, but too fast to stop suddenly if you need to. 
In this case what would you do ?

One option is to slow down your vehicle and look what is in front as headlights are focusing in straight line.

Second option is to go with adaptive headlight system.

Standard headlights shine straight ahead, no matter what direction the car is moving. When going around curves, they illuminate the side of the road more than the road itself. Similarly, when a vehicle with standard headlights crests a hill, the headlight beams temporarily point upwards towards the sky. This makes it difficult for drivers to see the road ahead and for oncoming motorists to see the driver approaching.Adaptive headlights react to the steering, speed and elevation of the car and automatically adjust to illuminate the road ahead. When the car turns right, the headlights angle to the right. Turn the car left, the headlights angle to the left. This is important not only for the driver of the car with adaptive headlights, but for other drivers on the road as well. The glare of oncoming headlights can cause serious visibility problems. Since adaptive headlights are directed at the road, the incidence of glare is reduced.

A car with adaptive headlights uses electronic sensors to detect the speed of the car, how far the driver has turned the steering wheel, and the yaw of the car. Yaw is the rotation of the car around the vertical axis -- when a car is spinning, for example, its yaw is changing. The sensors direct small electric motors built into the headlight casing to turn the headlights. A typical adaptive headlight can turn the lights up to 15 degrees from center, giving them a 30-degree range of movement.

Adaptive headlights also benefit other motorists on the road. For example, when a vehicle turns around a bend in low-light conditions, standard headlights will temporarily point directly at oncoming traffic. This can lead to discomfort and temporary blindness for oncoming motorists. This problem is avoided with adaptive headlights, since their beams stay on the road and do not point at oncoming traffic. In addition, since headlight beams to not point at other motorists, it is safe for drivers who own a vehicle with adaptive headlights to use bi-xenon lights. Emitting a slightly blue-ish tint, these lights are brighter than standard lights and offer a clearer, more distinct view of the road ahead.

SLIPPER CLUTCH

What is slipper clutch & what advantages does the rider get riding a bike equipped with slipper clutch?

Bikes like KTM Duke 390,TVS Apache 200 ABS etc. are using slipper clutch now a days over normal clutches.

Let's check out what is this and how it works:

When you are riding at high speeds and suddenly you encounter a sharp corner – the obvious reaction would be to slow down by applying the brakes and shifting in lower gear. But what if you have lesser time and you want to shift 2-3 gears at a time? And when you do this, you do it at the cost of damaging the gear box and putting your safety at risk which arises due to engine braking force.

As a mechanism to reduce these issues, Slipper Clutch (also known as back torque limiter clutch) was introduced. Slipper Clutch helps by allowing the clutch to partially slip until the engine speed matches your own speed.

In normal clutches, the engine braking force is transmitted to rear wheel via chain drive (or shaft drive) which causes rear wheel to shake, jump or lose traction. This is the main concept behind slipper clutch to control rear wheel under hard braking and downshifting that causes the rear wheel to lose traction. It is particularly helpful especially on higher displacement bikes where the engine braking force is massive and may cause the motorcycle to go out of control, resulting in a high-speed collision/accident!

Advantages of Slipper Clutch

The following are the advantages of slipper clutch over normal clutch…

1. Slipper clutch reduces sudden forces on the inside of the transmission and hence, reduces wear and tear on the transmission
2. Correctly installed slipper clutch improves performance.
3. It can prevent disastrous rear wheel lock up in case of engine seizure or transmission failure.
4. It also reduces work of suspension by absorbing engine braking force hence less bumpy ride while cornering.
5. The rider does not need to concentrate on clutch operation which allows him concentrate on other things such as body posture, braking etc. while cornering.

3D PRINTING

Introduction:-

3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.

How does 3D printing work?

It all starts with making a virtual design of the object you want to create. This virtual design is for instance a CAD (Computer Aided Design) file. This CAD file is created using a 3D modeling application or with a 3D scanner (to copy an existing object). A 3D scanner can make a 3D digital copy of an object.

3D scanners
3D scanners use different technologies to generate a 3D model. Examples are: time-of-flight, structured / modulated light, volumetric scanning and many more.

Recently, companies like Microsoft and Google enabled their hardware to perform 3D scanning, for example Microsoft’s Kinect. In the near future digitising real objects into 3D models will become as easy as taking a picture. Future versions of smartphones will probably have integrated 3D scanners.

Currently, prices of 3D scanners range from expensive professional industrial devices to $30 DIY scanners anyone can make at home.

3D modeling software
3D modeling software also comes in many forms. There’s industrial grade software that costs thousands a year per license, but also free open source software, like Blender, for instance. You can find some beginner video tutorials on our Blender tutorials page.

When you are a beginner and the amount of choices are a bit overwhelming, we recommend to start with Tinkercad. Tinkercad has a free version and it works in browsers that support WebGL, for instance Google Chrome. They offer beginner lessons and has a built in option to get your object printed via various 3D printing services.

When you have a 3D model, the next step is to prepare it in order to make it 3D printable.

From 3D model to 3D printer

You will have to prepare a 3D model before it is ready to be 3D printed. This is what they call slicing. Slicing is dividing a 3D model into hundreds or thousands of horizontal layers and needs to be done with software.
Sometimes a 3D model can be sliced from within a 3D modeling software application. It is also possible that you are forced to use a certain slicing tool for a certain 3D printer.
When the 3D model is sliced, you are ready to feed it to your 3D printer. This can be done via USB, SD or wifi. It really depends on what brand and type 3D Printer you have.
When a file is uploaded in a 3D printer, the object is ready to be 3D printed layer by layer. The 3D printer reads every slice (2D image) and creates a three dimensional object.

TURBOPROP ENGINE

Turboprop Engine (Propeller turbine, turbo-propeller, prop jet, turbo-prop)

For relatively high take-off thrust or for low-speed cruise applications, turboprop engines are employed to accelerate a secondary propellant stream, which is much larger than the primary flow through the engine. The relatively low work input per unit mass of secondary air can be adequately transmitted by a propeller. Though a ducted fan could also be used for this purpose, a propeller is generally lighter compared to ducted fan could also be used for this purpose, a propeller is generally lighter compared to ducted fan engine and with variable pitch, it is capable of a wider range of satisfactory performance.

In general, the turbine section of a turboprop engine is very similar to that of a turbojet engine. The main difference is the design and arrangement of the turbines. In the turbojet engine the turbine is designed to extract only enough power from the high velocity gases to drive the compressor, leaving the exhaust gases with sufficient velocity to produce the thrust required of the engine. The turbine of the turboprop engine extracts enough power from the gases to drive both the compressor and the propeller. Only a small amount of power is left as thrust. Usually a turboprop engine has two or more turbine wheels. Each wheel takes additional power from the jet stream, with the result that the velocity of the jet is decreased substantially.

Figure shows a schematic diagram of a turboprop engine. The air enters the diffuser as in a turbojet and is compressed in a compressor before passing to the combustion chamber. The compressor in the turboprop is essentially an axial flow compressor. The products of combustion expand in a two-stage or multistage turbine. One stage of the turbine drives the compressor and the other drives the propeller. Thus the turbine expansion is used to drive both compressor as well as propeller and less energy is available for expansion in the nozzle. Due to lower speeds of propeller a reduction gear is necessary between turbine and the propeller. About 80 to 90% of the available energy in exhaust is extracted by the turbine while rest, about 10 to 20%, contributes the thrust by increasing the exhaust jet velocity.

Total thrust = jet thrust + propeller thrust

Turboprop engines combine in them the high take-off thrust and good propeller efficiency of the propeller engines at speeds lower than 800 km/h and the small weight, lower frontal area and reduced vibration and noise of the pure turbojet engine.

Its operational range is between that of the propeller engines and turbojets though it can operate in any speed up to 800 km/h.

The power developed by the turboprop remains almost same at high altitudes and high speeds as that under sea-level and take-off conditions because as speed increases ram effect also increases. The specific fuel consumption increases with increase in speed and altitude. The thrust developed is high at take-off and reduces at increased speed.

Advantages :-

1.      Turboprop engines have a higher thrust at take-off and better fuel economy.

2.      The frontal area is less than air screw so that drag is reduced.

3.      The turboprop can operate economically over a wide range of speeds ranging from low speeds, where pure jet engine is uneconomical, to speeds of about 800 km/h where the propeller engine efficiency is low.

4.      It is easy to maintain and has lower vibrations and noise.

5.      The power output is not limited as in the case of propeller engines (air screw).

6.      The multicast arrangement allows a great flexibility of operation over a wide range of speeds.

Disadvantages :-

1.      The main disadvantage is that at high speeds due to shocks and flow separation, the propeller efficiency decreases rapidly, thereby, putting up a maximum speed limit on the engine.

2.      It requires a reduction gear which increases the cost and also consumes certain energy developed by the turbine in addition to requiring more space.

BASIC TERMS OF THERMODYNAMICS

Thermodynamics: Basic Terms

Thermodynamics:  The branch of science that deals with the study of different forms of energy and the quantitative relationships between them.

System:  Quantity of matter or a region of space which is under consideration in the analysis of a problem.

Surroundings:  Anything outside the thermodynamic system is called the surroundings. The system is separated from the surroundings by the boundary. The boundary may be either fixed or moving.

Closed system:  There is no mass transfer across the system boundary. Energy transfer may be there.

Open system:  There may be both matter and energy transfer across the boundary of the system.

Isolated system:  There is neither matter nor energy transfer across the boundary of the system.

State of the system and state variable:  The state of a system means the conditions of the system. It is described in terms of certain observable properties which are called the state variables, for example, temperature (t), pressure (p), and volume (v).

State function:  A physical quantity is a state function in the change in its value during the process depends only upon the initial state and final state of the system and does not depend on the path by which the change has been brought about.

Macroscopic system and its properties:  If as system contains a large number of chemical species such as atoms, ions, and molecules, it is called macroscopic system. Extensive properties: These properties depend upon the quantity of matter contained in the system. Examples are; mass, volume, heat capacity, internal energy, enthalpy, entropy, Gibb's free energy. Intensive properties:  These properties depend only upon the amount of the substance present in the system, for example, temperature, refractive index, density, surface tension, specific heat, freezing point, and boiling point.

Types of thermodynamic processes:  We say that a thermodynamic process has occurred when the system changes from one state (initial) to another state (final).

Isothermal process:  When the temperature of a system remains constant during a process, we call it isothermal. Heat may flow in or out of the system during an isothermal process.

Adiabatic process:  No heat can flow from the system to the surroundings or vice versa.

Isochoric process:  It is a process during which the volume of the system is kept constant.

Isobaric process:  It is a process during which the pressure of the system is kept constant.

Reversible processes:  A process which is carried out infinitesimally slowly so that all changes occurring in the direct process can be exactly reversed and the system remains almost in a state of equilibrium with the surroundings at every stage of the process.

   

CHECK OUT WHY 4 STROKE ENGINES ARE MORE PREFERRED OVER 2 STROKE ENGINE !!

Even though power of two stroke engine is more than four stroke engine then why four stroke engine are used more?

ADVANTAGES OF 4 STROKE ENGINE :-

1. More torque :- In general, 4 stroke engines always make extra torque than 2 stroke engine at low RPM. Although 2 stroked ones give higher torque at higher RPM but it has a lot to do with fuel efficiency.
2. More fuel efficiency :- 4 stroke engines have greater fuel efficiency than 2 stroke ones because fuel is consumed once every 4 strokes.
3. Less pollution :- As power is generated once every 4 strokes & also as no oil or lubricant is added to the fuel; 4 stroke engine produces less pollution.
4. More durability :- We all know that more the engine runs, quicker it wears out. 2 stroke engines are designed for high RPM. If an engine can go for 10000 rpm’s before it wears out; a 4 stroke engine with 100 rpm will run for 100 minutes than the other 2 stroke engine which has a higher rpm of 500 & will run for only 20 minutes.
5. No extra addition of oil :- Only the moving parts need lubrication intermediately. No extra oil or lubricant is added to fuel.

DISADVANTAGES OF 4 STROKE ENGINE :-

1. Complicated design :- A 4 stroke engine has complex valve mechanisms operated & controlled by gears & chain. Also there are many parts to worry about which makes it harder to troubleshoot.
2. Less powerful :- As power gets delivered once every 2 rotations of crankshaft(4 strokes), hence 4 stroke is less powerful.
3. Expensive :- A four stroke engine has much more parts than 2 stroke engine. So they often require repairs which leads to greater expense.

So, overall the 4-stroke engines have some minor disadvantages but a lots of advantages which are more relevant.

DIFFERENCE BETWEEN CLOSED CYCLE GAS TURBINE AND OPEN TYPE GAS TURBINE

The difference between closed cycle gas turbine and open cycle gas turbine can be done on the basis of source of heating, types of working fluid, circulation of air, wearing capacity of turbine blades, installation, maintenance cost and much more. The basic difference between them is the circulation of working fluid. In the closed cycle gas turbine the same working fluid is circulated again and again within the turbine but in the open cycle gas turbine the working fluid i.e. air is replaced again and again while flowing through the gas turbine.

Comparison of closed cycle gas turbine and open cycle gas turbine in tabular form:

S.no	Closed Cycle Gas Turbine	Open Cycle Gas Turbine
1.	In this first the air is compressed in the compressor and then heated in a heating chamber. As the air is heated by an external source, so the amount of the gas remains same.	Here the compressed air is heated in the combustion chamber. So the products of combustion gets mixed with the heated air and hence the amount of gas does not remain same.
2.	In closed cycle gas turbine, the gas that comes out from the gas turbine passes into the cooling chamber.	In open cycle, the gases coming out from the gas turbine is exhausted in the atmosphere.
3.	The working fluid is circulated continuously.	The working fluid is replaced continuously.
4.	Any other fluid that possesses better thermodynamic properties like helium can be used.	Here only air can be used as the working fluid.
5.	No earlier wear of the turbine blades, because the enclosed gas does not gets contaminated while flowing through the heating chamber,	Earlier wear of turbine blades,  as the air form the atmosphere enters the combustion chamber it gets contaminated.
6.	It is best suited for the stationary installation and marine uses because the air from the turbine is cooled by the circulating water.	It is best suited for the moving vehicle because the air from the turbine is discharged into the atmosphere.
7.	The maintenance cost of this type of turbine is high.	Its maintenance cost is low.
8.	More mass of installation per kW.	Less mass of installation per kW.

IN A 1.6L V6 ENGINE, WHAT DOES THE 1.6L REFER TO?

In a 1.6L V6 engine, what does the 1.6L refer to?

Engines are measured in litres. The parts of the engine where the fuel is burned to produce movement are called the cylinders – a car will usually have three, four, six or eight cylinders – and the volme of these cylinders is measured in litres. Simply,it is is the total displacement of all cylinders when piston moves either from TDC(Top dead center) to BDC(Bottom dead center) or BDC to TDC .Its also termed as stroke volume.

A 1.6 litre engine will have 1.6 litres of cylinder space altogether. 

1.6L = 1.6 Liters (or 1600 cubic centimeters or 1.6 decimeters)

V6 = 6 cylinders in a V shape.This type of engine is used in F1 racing - max rpm at 15,000. They use this engine because the pistons are light, small, the stroke is reduced, and this allows the engine to reach that insane rpm. 

So if it has six cylinders, each cylinder has a volume 1600/6 = 267 cc

A 1.6L engine might also be referred to as 1.6 in brochures. Sometimes, the size of the engine will be part of the name of the car.

DIFFERENCE BETWEEN LAMINAR AND TURBULENT FLOW

Difference Between Laminar and Turbulent Flow

S.no	Laminar Flow	Turbulent Flow
1.	It is a fluid flow in which the fluid layers move parallel to each other and do not cross each other.	It is a fluid flow in which the fluid layers cross each other and do not move parallel to each other.
2.	The laminar flow generally occurs in the fluid flowing with low velocity.	The turbulent flow occurs when the fluid flows with high velocity.
3.	Laminar flow occurs in the small diameter pipes in which fluid flows with low velocity.	Turbulent flow occurs in large diameter pipes in which fluid flows with high velocity.
4.	The fluid flow is laminar when the value of Reynolds number (Re) is less than 2000.	The fluid flow is turbulent when the value of Reynolds number is greater than 4000.
5.	Shear stress in laminar flow depends only on the viscosity of the fluid and independent of the density.	Shear stress in the turbulent flow depends upon the density of the fluid.
6.	The fluid flow is very orderly i.e. there is no mixing of adjacent layers of the fluid and they move parallel to each other and also with the walls of the pipe.	The fluid flow is not orderly i.e. there is mixing of adjacent layers of fluid with each other and they do not move parallel to each other and also with the walls of the pipe.

Summary of the Difference Between Laminar and Turbulent Flow

Laminar Flow

• The fluid flow in which the adjacent layers of the fluid do not mix with each other and moves parallel to each other, is called laminar flow.
• In the laminar flow, the fluid layer moves in straight line.
• The laminar flow always occurs when the fluid flow with low velocity and in small diameter pipes.
• The fluid flow having Reynolds number less than 2000 is called laminar flow.
• The fluid flow is very orderly i.e. there is no mixing of adjacent layers of the fluid and they move parallel to each other and also with the walls of the pipe.
• Shear stress in laminar flow depends only on the viscosity of the fluid and independent of the density.

Turbulent Flow

• The fluid flow in which the adjacent layers of the fluid cross each other and do not move parallel to each other, is called turbulent flow.
• In turbulent flow the fluid layers do not moves in straight line. They move randomly in zigzag manner.
• The turbulent flow occurs when the velocity of the fluid is high and it flows through larger diameter pipes.
• The fluid flow having Reynolds number greater than 4000 is called turbulent flow.
• The fluid does not flow in definite order. There is a mixing of different layers and they do not move parallel to each other but crosses each other.
• The shear stress in turbulent flow depends upon its density.
