FLERCYLINDRING, TVATAKTS INSPRUTNINGSMOTOR MED VEVHUSKOMPRIMERING

摘要

A multi-cylinder 2-stroke fuel injection engine of the crankcase compression type has a separate crank chamber associated with each cylinder and inlet, transfer and exhaust ports in each cylinder. The exhaust ports of the engine communicate with an exhaust manifold which communicates with the turbine of an exhaust gas driven scavenge compressor, and the impeller of the compressor communicates with an inlet manifold which communicates with the inlet ports of the engine so as to pressure charge each crank chamber and thus increase the mass of air subsequently pumped to the associated cylinder by way of its transfer port.
