FUEL DIRECT INJECTION TYPE INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To easily and efficiently reduce pressure in a combustion chamber when starting an engine, by using an air-fuel mixture injection injector, in a fuel direct injection type internal combustion engine of a plurality of cylinders. SOLUTION: This fuel direct injection type internal combustion engine operates an air injection valve of the air-fuel mixture injection injector 40 for opening in a predetermined time after the air-fuel mixture injection timing into the combustion chamber 30 by the air-fuel mixture injection injector 40 in response to an operation state of the engine 20. The engine 20 has front and rear cylinders 23a and 23b different in phase. Front and rear air supply passages 66a and 66b to the respective air-fuel mixture injection injectors 40 arranged in the respective cylinders 23a and 23b, are mutually connected to communicate with each other.
