    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.

    Abstract: Scavenging a cylinder of an engine with fuel-free fresh air and injection with atomized liquid fuel by a pressurized gas are accomplished independently, at specific moments during by the operating cycle of the engine. The fuel is atomized and injected into the cylinder by gases tapped from cylinder of the engine. The injection device can comprise a reservoir in which the gases tapped from cylinder are stored. The gases can be tapped from cylinder by a pneumatic injector when the valve opens.

    Abstract: A two-stroke engine having at least one cylinder in which a piston is movably accommodated, with a crank case communicating with one end of the at least one cylinder. Air is admitted to the crank case and at least one pipe admits unmixed air from the crank case to a cylinder transfer port. The fuel is pneumatically injected into the cylinder by way of a pneumatic injector and a pipe connected to the crank case by a valve and forming a volume of pressurized air connected to the pneumatic injector supplies the pneumatic injector with pressurized air for atomizing the fuel. An exhaust pipe is connected to the at least one cylinder by an exhaust port located in a position offset in a direction of travel of the piston with respect to the cylindrical transfer port of the cylinder. At least one restricting element is disposed inside the exhaust pipe in a vicinity of the cylinder for restricting a passage of the exhaust gases, with the restricting element being controlled and adjusted as a function of at least one engine operating parameter.
