Otto Cycle Engine Diagram. The technically correct term is actually four stroke cycle. Using the engine stage numbering system we begin at the lower left with stage 1 being the beginning of the intake stroke of the engine.
Here we understand what is otto cycle t s diagram and otto cycle p v diagram. The pressure is near atmospheric pressure and the gas volume is at a minimum. Adiabatic and isentropic transformation without heat exchange with the outside.
The figure shows a p v diagram of the otto cycle.
The following diagrams represent the otto cycle in a 4 stroke engine in both pv and ts coordinates. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy. Using the engine stage numbering system we begin at the lower left with stage 1 being the beginning of the intake stroke of the engine. Inlet valve opens at 5 10 0 before the top dead center.
