Ignition timing sensor system for a swirl chamber type diesel engine
An ignition timing sensor system is described for use in a Diesel engine having a swirl chamber that connects with a main combustion chamber via a communicating port. The port directs air from the main combustion chamber into the swirl chamber substantially tangentially to the wall surface of the swirl chamber to swirl the air in a given direction within the swirl chamber. The system comprises: a fuel injection nozzle opening into the swirl chamber and injecting fuel into the swirl chamber along the given swirl direction; a glow plug mounted in the swirl chamber and including a glow portion extending into the swirl chamber and contacting the fuel injected into the swirl chamber by the fuel injection nozzle; and an ignition timing sensor mounted in the wall of the swirl chamber and positioned opposite the glow portion of the glow plug with respect to the fuel injection nozzle. The ignition timing sensor includes an input end that receives combustion light for sensing ignition timing. The ignition timing sensor is retracted into the wall of the swirl chamber to prevent the ignition timing sensor from protruding into the swirl chamber.
