    摘要: A direct fuel injection-type spark-ignition internal combustion engine is disclosed. The engine comprises a spark plug, a cavity formed on the top surface of the piston, and a fuel injection valve for injecting fuel into the cavity in nearly the flat fan shape having a relatively small thickness. An opposing side wall of the cavity opposite to the fuel injection valve, for leading the fuel to the vicinity of the spark plug, has an arcuate portion having a plurality of arcuate shapes in a plan view. The radius of arcuate shape at the both side parts of the arcuate portion in a plan view is smaller than the radius of arcuate shape at the center part of the arcuate portion in a plan view. The opposing side wall has a deflecting portion to deflect the fuel toward the inside of the cavity.

    摘要: An electronically controlled blow-by gas returning apparatus for an internal combustion engine which corrects a fuel injection amount is disclosed. This blow-by gas returning apparatus is provided with an electronically controlled ventilation valve and a control unit. The ventilation valve regulates the flow rate of blow-by gas. The control unit controls the ventilation valve. The control unit controls the opening degree of the ventilation valve such that the actual value of the opening degree of the ventilation valve is maintained at a demand value of the opening degree of the ventilation valve. The control unit corrects the demand value based on the degree of enrichment of the actual air-fuel ratio in relation to a target air-fuel ratio and an intake air amount which is the amount of air fed into a combustion chamber of the internal combustion engine.

    摘要: A hybrid electronic control unit sends a combustion start command to an engine ECU when the rotation speed of an engine reaches a combustion start rotation speed by engine cranking. The engine ECU sends an initial explosion advance notification to the hybrid electronic control unit when the crank position of the engine reaches a specific position prior to an ignition timing of an initial explosion cylinder by a preset crank angle θec. Ignition of the initial explosion cylinder is performed at a timing when the crank position is further rotated by the preset crank angle θec. The hybrid electronic control unit sends a torque command in view of a counter torque Tα to a motor ECU after elapse of a preset time period tv. The preset time period tv is the sum of a first time period t1 between reception of the initial explosion advance notification and the ignition timing of the initial explosion cylinder in the engine and a second time period t2 between the ignition timing of the initial explosion cylinder in the engine and appearance of torque effect caused by the ignition of the initial explosion cylinder on a driveshaft. Such control timely reduces the torque effect caused by the initial explosion of the engine on the driveshaft.

    摘要: An engine includes a variable valve timing mechanism to adjust the valve overlap of intake valves and exhaust valves in accordance with the running state of the engine. The engine operates either in stratified charge combustion mode or in homogenous charge combustion mode in accordance with the running state of the engine. When, for example, the VVT cannot operate normally due to lack of hydraulic pressure, an ECU judges that the state of the VVT is not suitable for stratified combustion and forces the engine to operate in the homogenous combustion mode regardless of the running state of the engine. As a result, the combustion state of the engine does not deteriorated and the amount of NOx in the exhaust gas does not increase.

    摘要: When a start command of an engine is given in the presence of the driver's power demand, the start control sets the ignition timing of the engine to a power demand ignition timing, in order to enable quick output of a large power from the engine in response to the driver's power demand. When the start command of the engine is given in the absence of the driver's power demand in a vehicle drive state, there is little possibility of the occurrence of gear chattering noise because of application of a torque to a driveshaft. 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.
