Auxiliary injector of the mixer to improve the flow characteristics of the mixer around the electrode of the spark plug

摘要

An object of the present invention is to introduce the mixer into the combustion chamber through the spark plug to facilitate the stratification of the air-fuel ratio distribution around the electrode and to form a strong vortex by air flow to increase the combustion efficiency of the mixer around the electrode of the spark plug. It is to provide a secondary injector of the mixer for improving the flow characteristics.;The present invention for achieving the above object;A spark plug fastened to a cylinder head to ignite the mixer of an engine,;A mixer supply passage formed between the center electrode of the spark plug and the housing to introduce the mixer into the combustion chamber;;A mixer storage tank connected to the surge tank;;An air pump feeding air to the spark plug;;A solenoid valve provided in the middle of a connecting pipe connecting the mixer storage tank and the mixer supply passage to open the connecting pipe immediately before the spark time and to supply the mixer; And;And an electronic controller for controlling the opening and closing time of the solenoid valve.
