Diesel engine with prechamber having a straight and inclined flame passage.

摘要

The engine comprises at least one cylinder in which a piston (26) travels and a swirling prechamber (20) communicating with the cylinder by way of a straight transfer passage (30). The prechamber (20) has a plane of symmetry (24) passing through the axis of the cylinder and comprises a glow plug (21), the axis of symmetry (23) of which is located in the plane of symmetry (24). The longitudinal axis (32) of the transfer passage (30) forms an angle alpha not equal to zero with the plane of symmetry (24) of the prechamber (20). The upper section of the piston (26) is machined in order to form a cavity (36) of asymmetrical trefoil form in the extension of the transfer passage (30). <IMAGE>
