ABSTRACT:
An engine including at least one cylinder in which a piston moves delimiting a combustion chamber and a housing, with at least one opening for allowing fresh air to enter the combustion chamber and one pneumatic injection device. The fuel is atomized or sprayed and injected into the chamber by using a compressed gas. For small engine charges, a compressed gas is used, with the compressed gas being derived solely from the chamber or the housing of the cylinder of the engine, and for high engine charges, another compressed gas is used derived from a source outside the cylinder. The source outside the chamber may include a mechanical compressor driven by one of a two-stage engine or a turbocompressor.
