Abstract
【解決手段】ガソリンを筒内に直接噴射する液体燃料噴射弁と、気体燃料を筒内または吸気ポートに噴射する気体燃料噴射弁とを備え、エンジンの運転モードに応じてガソリンと気体燃料のいずれか一方を噴射し、運転条件に応じて成層燃焼と均質燃焼とを切り替え可能に構成されたバイフューエル筒内直噴エンジンの燃料噴射制御方法において、ガソリンと気体燃料の噴射切り替え時に(ステップS11肯定、ステップS17肯定)、液体燃料噴射弁の噴射圧を増大させて均質燃焼下で所定時間(T1,T2)噴射し、付着したデポジットを洗浄する(ステップS13、S14、S18)。洗浄後は、指示通りの燃料に切り替えて燃焼制御する(ステップS15、S19)。
