ELECTRONICALLY CONTROLLED FUEL INJECTOR FOR INTERNAL COMBUSTION ENGINE

摘要

PURPOSE:To prevent abnormal rise of combustion temperature in high load after the passage of predetermined time since the detection of acceleration condition of an engine by delaying ignition timing of correctively increasing fuel injection quantity when the air-fuel ratio of mixture is leaner than the theoretical one. CONSTITUTION:An acceleration condition detecting means A for detecting the acceleration condition of an engine, an air-fuel ratio detecting means B for detecting the air fuel ratio of mixture and an engine load detecting means C for detecting the engine load are provided. When air fuel ratio in the mixture is detected to be leaner than a theoretical air-fuel ratio under the high load condition for a predetermined period of time after the acceleration condition of engine is detected, ignition timing set by an ignition controlling means E according to the running condition is correctively delayed by a lean acceleration correcting means D or a fuel injection quantity set by a fuel injection quantity setting means F is controlled to be increased correctively.
