Abstract: A method for controlling intake flow of an internal combustion engine having an intake port including a helical passage and a straight passage both extending towards a common port end opening which opens to the combustion chamber of the engine, in such a manner that a minimum proportion of intake flow is directed through the straight passage during idling operation of the engine regardless of the temperature condition of the engine, a maximum proportion of intake flow is directed through the straight passage during loaded operation at any non idling load of the engine when the engine is not warmed up, and a proportion of intake flow increasing according to the level of engine load is directed through the straight passage during loaded operation of the engine when the engine has been warmed up. This method is performed by an intake passage switchover control valve system operated conveniently by utilizing intake vacuum under a proper switchover thereof which itself incorporates the engine load performance.

Abstract: A by-pass control system for an internal combustion engine provided with a mechanical supercharger arranged in an intake pipe of the engine. The supercharger is connected to a crankshaft by means of a clutch operated in accordance with the engine load as well as the engine speed. A system is provided for maintaining the clutch disengaged irrespective of the engine load and engine speed when the engine is cranking. The load applied to a starter is decreased during the cranking operating due to the positive disconnection of the supercharger from the crankshaft, so that the engine can be easily started.

Abstract: A fuel evaporation gas treating device arranged such that when a vehicle engine is operated a heat-sensitive means detects the temperature around the engine and the fuel system and the like, and if the temperature is within a proper temperature range, a changeover valve allows a carburetor bore and a canister to communicate with each other so that a fuel evaporation gas in the canister is introduced into the carburetor bore and burned through reduction, and on the other hand, when the detected temperature is higher or lower than the optimum value, the changeover valve causes the canister and the carburetor bore to be shut off from each other as well as allows the canister and the atmospheric air vent to communicate with each other so that the secondary air is introduced into the carburetor bore, thereby to make it possible to automatically control the introduction of the evaporation gas and the secondary air into the carburetor bore.
