ABSTRACT:
In a diesel engine with indirect injection, the precombustion chamber (18) and respective outflow duct (20) associated with each cylinder have a plane of symmetry which is tangential to the axis of the cylinder. In a preferred embodiment, the cylinder has an exhaust valve (13) whose axis (23) is near the plane of symmetry (21) of the precombustion chamber (18), and two inlet valves (8a, 9a) whose axes (24, 25) are arranged in a plane substantially parallel, or at any rate not greatly inclined, to the plane of symmetry (21) of the precombustion chamber (18).
