2. Operation of a single-cylinder
The Powertrain Unit is subjected to two types of applied loadings, those from the gas combustion cycle and those related to inertia phenomena.

Different forces
The gases in a cylinder produce a variable pressure during the cycle which, at the moment of combustion, generate a so-called « gas force » on the piston, a force which is the cause of its displacement and that of the engine’s traction.
Similarly, the moving parts (piston, rod, etc.), which are subjected, through the connecting rod/crank system, to accelerations, undergo so-called « inertial forces ».
Generalised forces, which represent the results of forces and moments when they are applied to the powertrain, enable...

2 Appendix : Piston kinematics
The movement of the piston in a theoretical cylinder without play and hence without tipping of the piston is controlled by the movement of the connecting rod. Now the movement of the latter may be broken down into a...
