A standard 20 to 1 otto cycle is used for the petrol and diesel cycles for diesel engines. It is higher than gasoline engines due to the way diesels burn and compress fuel.
A petrol (gasoline) engine can be an otto cycle engine or it may not be. Click the link.
The 4 stroke or 4 cycle engine was invented in 1876 Nicholas Otto in Germany. This is the earliest 4 stroke and is commonly called the Otto cycle engine. The Diesel 4 stoke was invented in 1893 by Rudolph Diesel in Germany.
diesel cycle
It is based on the Otto Cycle operation ...
The otto cycle is the technical name for the 4 stroke engine. so a Gasoline or Petrol engine.
The maximum Thermal Efficiency of Petrol Engine or Gasoline Engine or Otto Cycle Engine is about 25-30%.
Because diesel is ignited of heat and high high compresion not a spark on lower compresion petrol engine. If you use diesel in a petrol you will end up with your engine knocking and pre-detonation followed by your engine blowing up pretty bad.
We use cut-off ratio in diesel cycle and not in Otto cycle because it is cost effective.

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))
Otto cycle using SI engine is write r wrong Otto cycle using SI engine is write r wrong
