The four strokes refer to intake, compression, combustion and exhaust strokes that occur during two crankshaft rotations per working cycle of Otto Cycle.
The efficiency of the Otto cycle is influenced by factors such as compression ratio, combustion process, and heat transfer. These factors impact the amount of work produced by the engine relative to the energy input.
We use cut-off ratio in diesel cycle and not in Otto cycle because it is cost effective.
The heat addition and rejection processes in otto cycle are of constant volume, whereas in brayton cycle, they are of constant pressure.

The thermal efficiency of an internal combustion engine using the Otto cycle is a measure of how effectively it converts heat energy from fuel into mechanical work. The Otto cycle, which consists of four processes (intake, compression, power, and exhaust), plays a key role in determining the engine's thermal efficiency. By optimizing the compression ratio and combustion process within the Otto cycle, engineers can improve the engine's thermal efficiency, resulting in better fuel economy and performance.
The otto cycle is the technical name for the 4 stroke engine. so a Gasoline or Petrol engine.

It is based on the Otto Cycle operation ...
the difference is the heat addition type In Otto Cycle the heat addition is Isochoric ((constant volume)) In Diesel Cycle the heat addition is Isobaric ((constant pressure))
in otto cycle the burning of fuel is instantaneously therefore a very small voulme is required for burning of fule

The formula to calculate the thermal efficiency of an Otto cycle engine is: Thermal Efficiency 1 - (1 / compression ratio)
