How many strokes, or cycles, does one engine cycle take? How many revolutions does the motor shaft make?

When a combustible mixture burns in an internal combustion engine, the temperature first rises significantly to 1600 ° C – 1800 ° C and the pressure on the piston increases, the gases expanding, pushing the piston and crankshaft, performing mechanical work. In this case, the gases are cooled, since part of their internal energy is converted into mechanical energy.
The working cycle of the engine takes place in four strokes (strokes) of the piston, while the crankshaft makes two revolutions.
