Patent number: 6840203Abstract: Engine starting performance is enhanced by a brushless motor having no rotor position detecting sensor. In the first place an engine is rotated forward and then is reversely rotated to overcome a high load region of the engine. Then, the engine is accelerated and rotated forward and started. In a light load region of the engine, the engine is immediately accelerated and normally rotated. It is judged whether the region of the engine is the high load region or light load region based on the rotation speed when the starting operation is started. After the starting operation is started, if the forward rotation speed reaches a first speed, and a second speed which is higher than the first speed is obtained even after predetermined time is elapsed, an immediate starting-judging section 36 outputs a detection signal to a starting/normal rotation control section 37.Type: GrantFiled: June 17, 2003Date of Patent: January 11, 2005Assignee: Honda Giken Kabushiki KaishaInventors: Tsutomu Wakitani, Toshinori Inagawa

Patent number: 6834632Abstract: A stop and start control apparatus of an internal combustion engine prevents fuel supplied in a specific cylinder at the time of stopping the engine from being discharged in an unburned state. When an ignition switch is turned off in a state that the unburned fuel is sealed in the combustion chamber of a specific cylinder during idling stop, the unburned fuel is combusted to prevent the unburned fuel from being discharged. The vibration occurring at that time can be suppressed by rotating the motor generator in the counter direction to the rotation direction of the crankshaft. After the unburned fuel is sealed in the combustion chamber of the specific cylinder, if it is estimated that the unburned fuel is discharged, the exhaust valve corresponding to the specific cylinder is closed at the predetermined timing, or the unburned fuel is combusted, whereby the unburned fuel is prevented from being discharged. Thus, deterioration of emission can be avoided.Type: GrantFiled: January 23, 2004Date of Patent: December 28, 2004Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kenji Kataoka, Yasushi Kusaka
