The ”four stroke petrol engine’ is based on
Carnot-cycle
Otto-cycle
Diesel-cycle
Boyle’s-cycle
Otto-cycle
A four-stroke engine (also known as four-cycle) is an internal combustion engine in which the piston completes four separate strokesโintake, compression, power, and exhaustโduring two separate revolutions of the engineโs crankshaft, and one single thermodynamic cycle. The earliest of these to be developed is the Otto cycle engine developed in 1876 by Nikolaus August Otto in Cologne, Germany, after the operation principle described by Alphonse Beau de Rochas in 1861.
