    摘要： A vehicular damping control system that executes damping control that suppresses sprung mass vibration in the vehicle by controlling a power source mounted in a vehicle changes the control mode of the damping control according to the operating range of the power source. Changing the control mode of the damping control according to the operating range of the power source enables the vehicular damping control system to improve coordination between the damping control and other control related to the power source, for example, and thus execute appropriate damping control.

    摘要： Fuel-vapor evaporating from a fuel tank is led through a vapor pipe and absorbed in a charcoal canister. Fuel-vapor stored in the charcoal canister is supplied to an inlet pipe when a purge valve is opened when the engine is driven, because the pressure in the inlet pipe is low. Fuel-vapor is then burned as fuel in the engine. If the opening of the purge valve is suddenly increased at the start of the purge, the air fuel ratio control is disturbed. Therefore, the purge rate is gradually increased and the vapor concentration of the fuel-vapor purged from the charcoal canister is learned, and the change rate of the purge rate is made small because the air-fuel ratio control may be disturbed when the vapor concentration is not learned enough.

    摘要： The engine stop control of the invention uses a correction factor k based on an ambient temperature Tdp in the vicinity of a delivery pipe to set an engine-stop criterion fuel pressure Pref as a fuel pressure of ensuring the sufficient startability of an engine and preventing the vapor generation. The engine stop control stops the operation of the engine after a decrease in fuel pressure Pf in the delivery pipe below the engine-stop criterion fuel pressure Pref. This arrangement effectively prevents the fuel oil-tight leaked from fuel injection valves from being accumulated in cylinders of the engine and thus restrains the poor emission, which may be caused by direct discharge of the fuel accumulated in the cylinders at a restart of the engine. The engine stop control of the invention also reduces the frequency of operation of a relief valve, which works to prevent an excessive increase in fuel pressure Pf in the delivery pipe, thus enhancing the durability of the relief valve.

    摘要： The air/fuel ratio (A/F) controller for an internal combustion engine having an upstream catalyst, a hydrocarbon-adsorbent exhaust purification (HAEP) catalyst that is disposed downstream from the upstream catalyst, an upstream A/F sensor disposed upstream from the upstream catalyst, a downstream A/F sensor disposed downstream from the HAEP catalyst, a middle A/F sensor disposed between the upstream catalyst and the HAEP catalyst, an A/F main feedback (F/B) control unit, and an A/F sub-F/B control unit. The A/F main F/B control unit performs main F/D control such that the exhaust A/F detected by the upstream A/F sensor is kept at a specific main F/B target A/F. The A/F sub-F/B control unit performs sub-F/B control such that the exhaust A/F detected by the downstream A/F sensor is kept at a specific sub-F/B target A/F during hydrocarbon desorption from the HAEP catalyst.

    摘要： An exhaust purifier for an internal combustion engine is capable of properly heating a catalyst in consideration of a deterioration with time and manufacturing variation in an electric heater that heats the catalyst.The exhaust purifier has the catalyst 4 disposed in an exhaust pipe, the electric heater for forcibly heating the catalyst 4, a power source for supplying power to the heater, an estimate unit for estimating the temperature that the catalyst 4 will reach, a comparator for providing the difference between the estimated temperature and a target temperature, and an operation controller for controlling the operating conditions of the engine according to the temperature difference. The estimate unit measures the voltage and current of the heater, calculates the resistance or power of the heater according to the voltage and current, and estimates the temperature. The operation controller adjusts the quantity of intake air and ignition timing, or adjusts ignition timing and then the quantity of intake air to maintain an engine speed, or, if a battery 6 is abnormal, adjusts the quantity of intake air and ignition timing to increase the temperature of exhaust gas.
