上装置。[Claims for Utility Model Registration] (1) In a multi-cylinder independent intake engine having a throttle valve in the intake passage of each cylinder, a communication pipe is provided that communicates the intake passage of each cylinder, and the communication pipe is provided with:
An independent air intake characterized in that an air valve is connected to the communication pipe for metering and inhaling air for fast idle according to the warm-up condition of the engine, and a cold start injector is provided downstream of the air valve in the communication pipe. A device that improves low-temperature startability of engines. (2) The cold start performance improvement device for an independently intake engine according to claim 1, wherein the cold start injector controls injection independently of an electronic control device of the engine. (3) A request for registration of a utility model in which a start injector time switch is provided that detects the warm state of the engine and turns on when the engine is cold, and the cold start injector is operated only when the start injector time switch is turned on. A low-temperature startability improvement device for an independent intake engine according to scope (2).
