Question

What is the main reason for throttle adjustment?

(a) To know the play of the acceleration pedal

(b) To decrease the engine speed

(c) To check the float

(d) Both decrease the engine speed andcheck the float

I had been asked this question in semester exam.

My doubt is from Petrol Engine Fuel Supply System topic in chapter Petrol Engine Fuel Supply System of Automotive Engine Design

Answer 1

Right answer is (a) To know the play of the acceleration pedal

The best I can explain: The accelerator pedal throttle valve should be completely closed, while on pressing pedal fully, it should be in the full open position. This should be checked and in case of some action, the linkage must be adjusted, as provided for in the manufacturer’s manual.
