特徴とするディーゼルエンジンの着火時期センサ。It has a light guide arranged so that its tip faces into the engine combustion chamber, and a cylindrical housing that holds the light guide while shielding the combustion chamber from outside air, and ignites from the state of combustion light guided by the light guide. In a diesel engine ignition timing sensor for detecting ignition timing, a chamber in which an orifice is formed is provided at the tip of the housing, and the surface of the light guide is caused by the flow of combustion gas caused by pressure changes during explosive combustion. An ignition timing sensor for a diesel engine, characterized in that it is swept.
