What governing mechanism is commonly implemented in compression-ignition diesel engines__________________?
Show answer Hide answer
Answer: A. quantity governing
Explanation
A diesel always draws a full charge of air and controls power by varying how much fuel is injected per cycle, which is quantity governing. A petrol engine throttles the air and fuel together to keep the mixture strength roughly constant, which is quality governing. The difference follows from compression ignition needing no fixed air-fuel ratio to ignite.
