Abstract
A four-stroke compression-ignition engine is supercharged by a compressor driven by a turbine. The turbine is fed in parallel by the exhaust manifold of the engine and by a passage provided with an auxiliary combustion chamber upstream of the exhaust manifold. The inlet and exhaust manifolds of the engine have distributing valves adapted to open these manifolds simultaneously during each transfer phase (exhaust plus inlet phase). The inlet and exhaust manifolds have a throttle to make gases heated by the auxiliary combustion chamber flow back into the cylinders of the engine in order to assist self-ignition.
