Title: Combustion condition detecting device for gasoline engine
Inventor: MIYATA SHIGERU
IPC: F02P17/12
Filed: 1991-12-10
Abstract: PURPOSE:To purify exhaust by detecting density of an ion current, flowing in a spark plug, to perform operation in a condition approximate to a limit of stable operation. CONSTITUTION:A primary circuit 11 of an ignition coil 1 is connected to a primary current interrupting means 4. A secondary circuit 12 is connected to spark plugs 3 through a distributor 2. The primary current interrupting means 4 concurrently serves for a generating means of ion current detection. In a limit operation condition of a lean limit of air-fuel ratio or a limit of an exhaust gas recirculation(EGR) amount, the nearer density of an ion current, flowing in the spark plug, approaches the limit the larger unevenness increases. A level of this unevenness is measured, and the limit of stable operation is detected from this level to control the air-fuel ratio or the EGR amount so as to approach the limit capable of performing stable operation. Thus, purification of exhaust and improvement of fuel consumption are contrived.
