20080208440 | CONTROLLER OF INTERNAL COMBUSTION ENGINE - A glow plug is provided in a combustion chamber of a diesel engine. An ECU diagnoses existence or nonexistence of a disconnection abnormality of the glow plug through a controller. When there is an abnormality in the glow plug, processing for cutting fuel supply of an abnormal cylinder, processing for increasing fuel injection quantity of a normal cylinder, processing for delaying injection timing of the abnormal cylinder, or processing for delaying valve timing of an intake valve of the abnormal cylinder is performed. Thus, suitable startability of the engine can be ensured even when the abnormality occurs in the glow plug. | 08-28-2008 |
20080228383 | Engine Control Device - Exhaust emission control is exercised to restrict the exhaust amounts [g] of HC, CO, NOx, and the like. However, since the intake air amount for startup unduly increases due to an engine speed overshoot for startup, the exhaust amounts of HC, CO, and NOx increase excessively. Therefore, there is a need for optimizing the intake air amount for startup. The present invention proposes an engine startup control method that assures excellent startability and low exhaust emissions (small gas amount). Disclosed is an engine control device for starting an engine (from its stop state). The engine control device includes a section for setting a target engine operating state of each combustion; a section for detecting an actual engine operating state of each combustion; and a section for computing a control parameter for each subsequent combustion in accordance with the target engine operating state of each combustion and the actual engine operating state of each combustion. | 09-18-2008 |

The start control accordingly sets the ignition timing of the engine to a vibration control ignition timing, in order to reduce the vibration of the vehicle body. When the start command of the engine is given in the absence of the driver's power demand in a vehicle stop state, on the other hand, application of a small torque may cause the occurrence of chattering noise. The start control accordingly sets the ignition timing of the engine to a chattering control ignition timing, in order to generate a certain level of torque that prevents repeated contact and separation of gears in a gear mechanism even in the event of an engine-induced torque variation. | 10-15-2009 |
