Abstract: A device for preventing fluctuations in the output torque of a spark-ignition internal combustion engine which result from irregular combustion of air-fuel mixture. According to the present invention, instead of the conventional idling device of which the idling jet is situated on the engine side of the edge of the throttle valve, a communication passage communicating at the downstream side of the throttle valves between a pair of intake passages each connecting the carburetor to the respective combustion chambers, an additionally fuel supplying means interposed in the communication passage and means for supplying a primary air from an air source to one of said pair of the intake passages are provided in the intake system of the internal combustion engine.

Abstract: PURPOSE:To effectively insulate the noise of an engine while securing its cooling action, by closing a ventilation hole, which is provided in the rear part of a sound insulation cover, when the engine is being accelerated. CONSTITUTION:When an engine 5 is being accelerated with a loud noise, a door 12 is maintained in closed position by a diaphragm means 13 for a prescribed time to keep a ventilation hole 9 closed. As a result, the lower part of an engine room 1 is completely enclosed by a sound insulation cover 7 so that the noise of the engine 5 greatly increased because of the acceleration is never emitted to the outside through the lower part of the engine room 1. The engine noise is thus entirely insulated by the sound insulation cover 7.
