筒内直接噴射式火花点火機関の燃焼室。[Scope of Claim for Utility Model Registration] (1) In a combustion chamber of an in-cylinder direct injection spark ignition engine formed by providing a recess at the top of the piston, the combustion chamber is formed between a shallow dish part and the center of the shallow dish part. A combustion chamber for an in-cylinder direct injection spark ignition engine, characterized in that it has a double structure with a shallow dish part formed at the bottom and a deep dish part having a smaller diameter. (2) The injection direction of the fuel into the combustion chamber is adjusted according to the vertical movement of the piston, so that when the injection timing is early, the injected fuel hits the shallow dish part, and when the injection timing is late, the injected fuel hits the shallow dish part. The combustion chamber of the in-cylinder direct injection spark ignition engine according to claim 1, wherein the combustion chamber is set to correspond to the deep dish portion.
