Abstract

A heat engine (1) provided with a plurality of cylinders having at least one inlet valve (3), at least one exhaust valve (4) and an auxiliary valve (6) forming part of a vacuum braking device (5); the valves (3, 4, 6) are controlled by an electronic control unit (8) which, in response to an actuating signal of the vacuum braking device, prevents the injection of fuel into the cylinders (2) and varies the timing sequence from a conventional four-stroke cycle to a two-stroke cycle in which the inlet valve (3) and the auxiliary valve (6) open alternately in accordance with each dead centre of the associated cylinder (2). <IMAGE>
