Abstract: PROBLEM TO BE SOLVED: To provide a power transmission of a vehicle which has a rotating device separately from a drive source, and capable of suppressing vibration and noise at a connection part between the rotating device and a power transmission pathway. SOLUTION: In a vehicle power transmission, a rotating device is connected to a power transmission pathway between a drive source and a wheel in a power transmittable manner, and when a predetermined condition is established, the rotating device is started. The vehicle power transmission has a vibration suppression means (Step S1 to Step S6) to suppress vibration generated in the power transmission pathway by starting the rotating device if the vibration is generated in the power transmission pathway by the rotational fluctuation of the drive source even when the predetermined condition is not established.

Abstract: PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal combustion engine which performs low-temperature combustion when SOx should be released by a SOx holding agent, stabilizing the operation of the internal combustion engine. SOLUTION: The SOx holding agent 14 is provided in an engine exhaust passage 7 for holding SOx in exhaust gas from the internal combustion engine which selectively performs first combustion, where the generation amount of soot in a combustion chamber 2 is more than the peak amount of inactive gas in the constant condition of a fuel injection timing, and second combustion, where the generation amount of soot in the combustion chamber is less than the peak amount of inactive gas. The SOx holding agent holds SOx in exhaust gas when the air-fuel ratio of the exhaust gas flowing therein is lean, and it releases SOx being held when the air-fuel ratio of the exhaust gas flowing therein is an approximately stiochiometric air-fuel ratio or rich. When SOx should be released by the SOx holding agent, rich exhaust gas is supplied to the SOx holding agent while executing the first combustion after reducing the cooling performance of cooling water for the internal combustion engine.

Abstract: PROBLEM TO BE SOLVED: To optimally control the combustion state of a diesel engine.
SOLUTION: Cylinder pressure sensors 29a to 29d detecting pressures in combustion chambers are installed in the cylinders of the diesel engine 1. Based on outputs from the cylinder pressure sensors, the electronic control unit (ECU) 20 of the engine calculates a crank angle θmax at which the product PV of a cylinder pressure and an actual cylinder displacement becomes maximum, calculates a period ΔT from the start of fuel injection to θmax, and feedback-controls the opening of an EGR valve 35 controlling the supplied amount of EGR gas to the engine so that the calculated ΔT becomes a target value determined based on an accelerator opening and an engine speed at present. Since ΔT can be calculated without increasing the calculation load of the electronic control unit 20 of the engine, an increase in the calculation load is not induced and the amount of EGR gas (EGR rate) can be accurately controlled to an optimum value.
