Anti-after-burning system in an internal combustion engine.

摘要

The known anti-after-burning system in an internal combustion engine provided with a governor device, in which a governor spring (109) is stretched between a governor lever (103) and a governor control lever (105) and said governor lever is connected to a carburettor throttle lever (101) and a stoppage device for stopping an engine by grounding a primary wire of an ignition circuit, is improved. The governor control lever is provided with a grounding section (113) for grounding the primary wire of the ignition circuit as a result of rotation to an engine low-speed side. The governor lever and one end of the governor spring are connected so as to be relatively rotatable and so as to have a freedom only with respect to the direction of contraction of the governor spring. Furthermore, the governor spring is constructed in such manner that when the governor control lever is at the position for grounding the primary wire of the ignition circuit, a coiled portion of the governor spring may butt against the governor lever to contrain rotation of the governor lever in the direction of opening the carburettor throttle valve.
