ABSTRACT:
A precombustion chamber for a compression-ignition internal combustion engine is formed in a cylindrical metal insert seated in the cylinder head. The internal cavity of the insert has a central cylindrical part which at its end adjacent the combustion chamber is connected through a frusto-conical part to a cylindrical second part of reduced diameter, the axis of which is displaced relative to the axis of the central cylindrical part in the opposite direction to an end part which communicates with the combustion chamber. A fuel injector is inserted into an upper end part of the insert, coaxial with the central cylindrical part of the cavity. The configuration leads to a reduction in exhaust smoke.
