制御手段が設けられたことを特徴とする、気化器
付きアルコールエンジンの始動時燃料増量装置。 In engines that use alcohol as the main fuel,
In addition to providing a vent lily in the intake passage of the engine, a fuel tank for storing a mixed fuel of alcohol and gasoline, a fuel supply path that communicates the vent lily and the fuel tank to supply the mixed fuel, and a fuel supply path that a first main jet inserted therein to control the amount of fuel supplied through the fuel supply path; a temperature sensor for detecting a state of the engine at a predetermined temperature or lower; and a starting state sensor for detecting a starting state of the engine. and a fuel supply bypass passage that communicates between a downstream portion and an upstream portion of the first main jet disposed portion of the fuel supply passage and can supply fuel bypassing the first main jet. a second main jet which is inserted into the fuel supply bypass passage and controls the amount of fuel supplied by the fuel supply bypass passage to determine an increased amount of fuel to be supplied to the vent lily; When starting an alcohol engine with a vaporizer, the alcohol engine is characterized by being provided with an on-off valve that can be shut off and a control means that controls opening of the on-off valve in response to detection signals from the temperature sensor and the starting state sensor. Fuel increase device.
