Two cycle engine with fuel injector

摘要

A two-cycle engine with fuel injector comprises an engine body, a crank case defining crank chambers for respective cylinders, the crank chambers being provided with intake ports, throttle bodies, and fuel injectors. The throttle bodies comprise throttle passages and throttle valve means and the injectors are inserted in the throttle passages downstream of the throttle valve means. The throttle passages are connected to each other through a balance passage at portions downstream the throttle valve means. An air chamber may be formed on the way of the balance passage. The throttle passages connected by the balance passage to one group of cylinders having phase difference of 180 DEG of the reciprocating stroke.
