Acyclism
Rotational non-uniformity of the crankshaft during an operating cycle.
Gases forces
Force generated by the variable pressure of gases on the piston.
Inertial force
Force generated by the acceleration of moving parts (piston, connecting rod, etc.).
Lambda or λ ratio
Ratio of the connecting rod centre line distance over the half-piston stroke.
Very widely used by engine manufacturers as it is involved in numerous expressions of forces, torques, speeds, and accelerations for combustion engines.
Inertia flywheel
Rotating inertia attached to the crankshaft with...

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...
