What is automobile, what is otto ,dual,diesels cycle difference

Question

Accepted Answer

The question is about the basics of automobile engines and the differences between Otto, Dual, and Diesel cycles.

Automobile is a vehicle powered by an engine that converts fuel into mechanical energy.
Otto cycle is a four-stroke combustion cycle used in gasoline engines.
Dual cycle is a modified version of the Otto cycle that includes a constant volume heat addition process.
Diesel cycle is a four-stroke combustion cycle used in diesel engines.
The main difference between these cycles is the way in which fuel is ignited and burned.
Otto cycle uses spark ignition, while Diesel cycle uses compression ignition.
Dual cycle combines both spark and compression ignition.
Diesel engines are more fuel-efficient than gasoline engines due to their higher compression ratios.
However, gasoline engines are generally more powerful and produce less noise and vibration.
The choice of engine type depends on the specific application and requirements.
