Title: Internal combustion engine control stop method and device for the same
Inventor: FROESCHL JOACHIM
IPC: B60W20/00
Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To ensure eliminating a fresh mixture in an internal combustion engine, thereby restricting emission of harmful substances during subsequent starting of the engine by, while interrupting fuel injection when an ignition key is turned to an 'OFF' position, keeping firing and maintaining a predetermined engine speed before bringing the engine to a stop. SOLUTION: When an ignition system is switched 'OFF' while an engine 10 is running, the ignition system is kept operating while a control unit 22 immediately stops fuel injection via an engine control unit 24. Simultaneously a starter-generator 14 is driven to keep an engine speed at a level equivalent to that when the ignition system receives the 'OFF' signal during a period through which a crankshaft turns two complete turns, thereby burning a fresh mixture in an intake cycle and a combustion chamber. After the crankshaft has completed turning two turns, the starter-generator 14 quickly stops the engine 10. This effectively restricts the amount of harmful substances emitted when the engine is restarted.
