Title: Control device for pre-mixed combustion compression ignition engine
Inventor: OTSUBO YASUHIKO
IPC: F02D41/40
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent pre-ignition of a pre-mixed combustion compression ignition engine. SOLUTION: Fuel is injected in each cylinder of an engine 1 at an intake stroke or a compression stroke, to form pre-mixed fuel gas. The pre-mixed fuel gas is ignited and burned by compression. Excessive increase in burning velocity of the pre-mixed fuel gas causes pre-ignition, resulting in increasing vibrations and a NOX exhaust amount. An electronic control unit(ECU) 30 controls the opening degree of an EGR valve 23 of the engine, so that actual exhaust NOX concentration, detected by an NOX sensor 71 which is arranged in an exhaust passage 3, becomes a target NOX concentration, which is pre- mixed and proper, at a time of pre-mixed combustion. By adjusting an EGR amount according to the actual exhaust NOX concentration, the burning velocity of the pre-mixed fuel gas is controlled to be within a proper range, resulting in preventing the occurrence of pre-ignition.
