Stratified-charge two-stroke cycle engine

摘要

A stratified-charge two-stroke cycle scavenged spark-ignition engine 1 includes a piston (2) reciprocal in a cylinder (3) between a combustion chamber 4 and a crankcase (5). A carburetor (17) is mounted to the crankcase substantially coaxially with the piston to afford narrow engine design. An elongated scavenging air passage (14) extends between the crankcase and the combustion chamber and has a length substantially greater than that of a fuel-air transfer passage (7), and the height of piston (2), to reduce fuel mixture in the scavenging air passage and afford substantially only air at an air inlet port (16), which port is between fuel-air mixture inlet port (8) and exhaust port (13).
