Combustion chamber for IC engine with shaped piston head |
摘要 |
A piston (2) slides axially in each cylinder of the engine, with a head block (4) mounted above each cylinder to define a combustion chamber (1). The piston head includes a cavity or bowl (6) which is open towards the head block, and which has a plan view cross-section of an ellipsoid. The principal axis and generatrices of the ellipse shape of the bowl are parallel to the longitudinal axis of the piston. The bowl may alternatively be shaped as two coincident ellipsoid shapes of dimensions determined according to given relationships between their relative sizes and the diameter of the cylinder.
