ION DETECTING DEVICE DETECTING ION CURRENT IN COMBUSTION CHAMBER OF DIESEL ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a device and method to detect combustion conditions using ion signals for use in a feedback control of a reciprocation engine. SOLUTION: The ion signals are used as a feedback signal to control EGR and diesel injection timing. The device is an ignition system with a spark plug type of sensor. The ignition system is used to provide a cold start mechanism for diesel engines and start of combustion for spark ignition engines. The ignition is combined with ion detecting feedback that can control the engine. COPYRIGHT: (C)2008,JPO&INPIT
