摘要： An onboard load control apparatus and a method for detecting a fault of an onboard electrical load with high accuracy are disclosed. The control apparatus comprises an onboard battery mounted on an automotive vehicle, an electrical heater for electrically heating an electrical load such as an electrically-heated catalyst supplied with power from the onboard battery, an auxiliary relay for turning on/off the power to the electrical heater from the onboard battery, and an ECU for controlling the on/off operation of the auxiliary relay. The apparatus further comprises an engine speed detector for detecting the engine speed of the internal combustion engine and a fault judgement unit for judging whether the electrical heater is normal or faulty on the basis of the fluctuation amount of the engine speed of the internal combustion engine detected by the engine speed detector before and after switching the auxiliary relay. A fault of the electrical load is judged by detecting the voltage across the onboard battery while taking the fluctuation amount of the same voltage into consideration. The apparatus further comprises a load condition holder for holding the load condition of a specific load while the engine speed or the battery voltage is detected.

摘要： A device for detecting deterioration of a catalyst in an internal combustion engine having a heater on the upstream side of a catalytic converter provided in an exhaust gas passage, the device being capable of expanding the deterioration determination conditions of the catalyst. It is determined whether the conditions, except the temperature condition, are all obtained among the conditions for detecting deterioration of the catalytic converter. When the conditions, except the temperature condition, are all obtained, an electric power is supplied from a power source to the heater to satisfy the temperature condition. Deterioration of the catalyst can be reliably detected if the electric power is supplied to the heater only when the engine is in the idling operation condition and if deterioration of the catalyst is detected when the time for supplying electric power to the heater has become larger than a predetermined period of time. The heater may be one contained in the electrically heated catalyst.

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.
