Zusammenfassung:	To provide an engine capable of being combined with a conventional exhaust gas treatment system including trivalent catalyst, and to reduce fuel consumption in the same power level by achieving high compression ratio by increasing durability of detonation, of the engine.SOLUTION: A gasoline internal combustion engine has a combustion chamber 4 and a precombustion chamber 13 communicated to the combustion chamber 4 to each cylinder 2. A first spark plug 11 is related to the precombustion chamber, and a second spark plug 15 is related to the combustion chamber 4. Gasoline is injected by an injector device directly related to the combustion chamber 4 and/or an injector device disposed to inject the gasoline into an intake duct related to the cylinder. Further a device for directly injecting gasoline or air, or a mixture of the air and the gasoline into the precombustion chamber is not related to the precombustion chamber.SELECTED DRAWING: Figure 1 【課題】エンジンが従来の三価触媒を含む排気ガス処理システムと両立できるように、またエンジンのデトネーションに対する耐性を増加させて高圧縮比で構成されることにより、同じパワーレベルにおける燃料消費を低減する。【解決手段】ガソリン内燃エンジンが、各シリンダ２に対して、燃焼室４および燃焼室４と連通した予燃焼室１３を有する。第１スパークプラグ１１が予燃焼室に関連付けられるのに対し、第２スパークプラグ１５が燃焼室４に関連付けられる。燃焼室４に直接関連付けられたインジェクタ装置によって、および／または、シリンダに関連付けられた吸気ダクト中へガソリンを噴射するように配置されたインジェクタ装置によって、ガソリンが噴射される。ガソリンまたは空気または空気とガソリンの混合気を予燃焼室中へ直接噴射するための装置が予燃焼室に関連付けられていない。【選択図】図１
