Abstract: 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.

Abstract: An abnormality diagnosis device for diagnosing abnormality in a positive crankcase ventilation apparatus including a PCV passage, which is for supplying blow-by gas to an intake passage of an engine, and a PCV valve, which is for regulating the flow rate of blow-by gas in the PCV passage. The diagnosis device varies a control amount of the PCV valve to determine the occurrence of an abnormality in the PCV passage and PCV valve and performs abnormality diagnosis in a first determination mode when the amount of fuel components in the blow-by gas is less than a reference amount and in a second determination mode when the amount is greater than the reference amount. A varying amount of the control amount of the PCV valve in the second determination mode is smaller than that of the control amount of the PCV valve in the first determination mode.

Abstract: An ECU increases an engine rotation speed when the ECU determines that an inclination angle of an uphill is larger than or equal to a predetermined value, an accelerator is off and a vehicle speed in a direction opposite to a travelling direction of a vehicle, indicated by a specified range, is increasing. Subsequently, the ECU acquires an engine stall predicted vehicle speed, and calculates a predetermined value used in an immediate engine stall determination condition from a current rate of increase per unit time of a turbine rotation speed. Then, the ECU determines that immediate engine stall determination is affirmative when a rotation speed difference between the engine rotation speed and the turbine rotation speed becomes smaller than the predetermined value, and executes engine stall prevention control.

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.

Abstract: 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.
