Abstract
A two-stroke cycle diesel engine having: at least one two-stroke cycle power cylinder - piston assembly incorporating uniflow scavenging and having two horizontally opposed pistons, at least first and second scavenging ports and two crankcases which may perform crankcase compression; a pump assembly including at least one scavenging pump cylinder - piston assembly of the reciprocating type which is separate from and is driven by the power cylinder - piston assembly; and a scavenging air introducing device which introduces scavenging air compressed by the pump assembly to the first and the second scavenging ports through first and second passage systems, respectively; wherein the first passage system is interrupted before the pump assembly reaches its top dead center so that thereafter the scavenging air compressed by the pump assembly is all supplied to the second scavenging port which is adapted to generate strong swirl flows in the power cylinder when scavenging air at high pressure is supplied in a large amount.
