JOB INTERVIEW QUESTIONS:-

JOB INTERVIEW QUESTIONS:-

1.What is ATFT Technology used in Honda Hunk?
Ans.-ATFT means Advance Tumble Flow Induction Technology, 
Tumble flow means swirling. In this technology fuel air mixture from the carburetor into the engine cylinder with a swirl action. The advantage being one gets a more efficient burning of fuel hence more power and better fuel economy with lesser emissions.

2.Why we do not use same technology to start both SI /CI engine
Ans.-The S.I. or spark ignition engine uses petrol as a fuel and the C.I. or compression ignition engine uses diesel as a fuel. Both the fuels has different compression ratio.
In SI engine the compression ratio is 8-12:1.
In CI engine the compression ratio is 16-22:1.
So in case of SI engine, the compression ratio is not sufficient for fuel to burn so a spark plug is used, whereas in ci engine, the compression ratio is so high that due to its internal heat the fuel is combusted so there is no need for a spark plug. so the technology used in si engine is different from CI engine.

3.What is a Newtonian fluid?
Ans.-A Newtonian fluid possesses a linear stress strain relationship curve and it passes through the origin. The fluid properties of a Newtonian fluid do not change when any force acts upon it.
