Port-controlled two-cycle engine having scavenging |
摘要 |
A two-cycle engine includes a reciprocating piston reciprocable in a combustion chamber and interconnected with a crankshaft in a crankcase. A transfer channel selectively fluidly connects the crankcase with the combustion chamber so a fuel/air mixture in the crankcase enters the combustion chamber for discharging exhaust gas from the combustion chamber. The transfer channel has a constructive volume between an inlet window into the combustion chamber and an opening window into the crankcase such that the volume of essentially fuel-free air that is drawn into the transfer channel during an intake stroke is no more than 75% of the constructive volume of the transfer channel.
