CARBURETOR VS FUEL INJECTION SYSTEM EXPLAINED !!

Why do more and more motorcycles now a day have fuel-injection systems rather than carburetor?  

So here is our discussion Carburetor Vs Fuel Injection – Brief Discussion.

The carburetor is one of the most essential mechanical part on a motorcycle and many small engine machines. All engines require a proper mixture of air and fuel for combustion; this vital device known as the carburetor controls the ratio of the fuel/air mixture entering the engine.

The fuel injected system is controlled by a computerized fuel delivery system, while the ECU takes information from various sensors and determines how much fuel the engine receives based on this data. Other sensors deal with RPM, engine temperature, throttle position, and the crankshaft position.

Carburetor Vs Fuel Injection System :

1. Fuel injector gives a slightly higher engine performance and slightly more efficiency when running at the best fuel-air ratio. Throttle response is also a bit better.
2. Crucially, most carburetor problems can be fixed easily at the side of the road with an assortment of basic tools. An electronic fuel injection system, though, if it goes wrong, will usually require a new part – and that’s going to cost you. Repair is far more difficult. Today’s modern fuel injection systems require a computer to diagnose the problem.

Advantages of Carburetors:

* Easy to operate and cheap to replace.
* Quick servicing.
* On the go tuning and setting possible
* Can be opened up individually without disturbing the engine.

Disadvantages of Carburetors:

* Diaphragm inside is delicate and can tear which will end up to have it replaced.
* The tuning process needs a big screw driver and has to be done physically.
* There is a certain amount of lag in the process of fuel delivery.
Old technology.
* The air-fuel mixture ratio is not constant.

Advantages of Fuel Injection:

* Fuel delivery is optimum and fuel atomizing allows for complete combustion.
* Increase in fuel efficiency and power output.
* Acceleration sensitivity increases.
* The air fuel mixture can be changed on the go using different fuel maps pre-loaded on the ECU for variable power outputs.

Disadvantages of Fuel Injection:

* Servicing of the FI unit is cumbersome.
* If there is an ECU failure, the bike will seize to work.
* It costs a lot and the service and maintenance is costly as well.
* Producing new Fuel maps needs loads of expertise.
* Procuring new fuel maps is a costly affair.

It is fairly obvious that most automobiles will be changing to fuel injection systems due to the lower emissions. However, unless the cost of these systems decreases significantly then there will still be a massive following that will stick to carburetors. When looking at pure horsepower, the fuel injection system only delivers about 10 extra horsepower at peak.
