Scope of the exercise
Educational assembly by sub-assemblies, without brand or manufacturer reference. It does not prescribe tightening torques, clearances, tolerances, lubrication or operations of an actual engine.
The cycle is an ideal kinematic animation: no calculation of combustion, pressure, temperature or power. The valves have neither advance, nor delay, nor crossing; the 360° setting is the reference chosen for the TDC at the end of compression in the diagram.
Indicative educational score at the end of assembly: 100 − 5 × errors − 2 × indices, limited between 0 and 100.
