摘要： PROBLEM TO BE SOLVED: To provide a failure diagnostic system of a combustion improving means capable of inexpensively detecting failure of the combustion improving means with high detectablity with every corresponding cylinder. SOLUTION: An ECU 1A diagnoses failure of an air current control valve 58 arranged in an intake port 52a communicating with a combustion chamber 57 of an internal combustion engine 50 for improving a combustion state, and has a failure determining means determining the failure of the air current control valve 58 with every corresponding cylinder, based on average crank angle acceleration with every cylinder of the internal combustion engine 50 and an operation state of the air current control valve 58. Actually, the failure determining means determines that there is abnormality in the air current control valve 58 corresponding to the cylinder of detecting the average crank angle acceleration existing on the deceleration side, when the average crank angle acceleration exists on the deceleration side when the air current control valve 58 is operated and the average crank angle acceleration does not exist on the deceleration side when the air current control valve 58 is not operated.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection control device for internal combustion engine capable of improving uniformity of air-fuel mixture and controlling emission of hydrocarbon (HC) even if the inflow property of intake air is changed by a variable valve system.
SOLUTION: This fuel injection control device for internal combustion engine, provided with the variable valve system for changing an operation angle and a valve lift amount of an intake valve 16 and, when the intake valve 16 is delayed to open and the valve lift amount is small, injects fuel from a fuel injection valve 14 toward the lower part of the intake valve 16 (fuel locus fu). Thus, droplet fuel, being carried by a high-speed air current, excessively delivered to an exhaust side portion inside a cylinder can be controlled so that uniform air-fuel mixture can be generated inside the cylinder. On the other hand, when the intake valve 16 is quickly opened and the valve lift amount is large, the fuel is injected from the fuel injection valve 14 toward the center 16a of the intake valve 16.

摘要： PURPOSE:To efficiently increase a temperature of intake air without worsening fuel consumption at cold time, relating to an automatic speed change control device used together with an engine in which the intake air temperature is increased by actuating a mechanical supercharger at the time of cold operation. CONSTITUTION:In an electronic control unit(ECU) 21, when a cooling water temperature, detected by a cooling water temperature sensor 11, is low obtained, a supercharge 5 is actuated even in a low load region to increase a temperature of intake air by compression. In the ECU21, a target intake air temperature is set based on the cooling water temperature and compared with the actual intake air temperature, detected by an intake air temperature sensor 17, to delay a shift up of an automatic transmission 30 only in the case of the actuate intake air temperature lower than the target intake air temperature. In the case of the actual intake air temperature higher than the target intake air temperature, the shift up is performed as in normal, so that an unnecessary low speed side gear operational region is prevented from spreading.
