摘要： The abnormality diagnosis system 1, 1', 1" of an ammonia detection device 46, 71 comprises: an air-fuel ratio detection device 41, 72 arranged in the exhaust passage 22 at the downstream side of the catalyst 20; an air-fuel ratio control part 51 configured to control an air-fuel ratio of exhaust gas; and an abnormality judgment part 52 configured to judge abnormality of the ammonia detection device. The air-fuel ratio control part performs rich control making the air-fuel ratio of the inflowing exhaust gas richer than a stoichiometric air-fuel ratio. The abnormality judgment part judges that the ammonia detection device is abnormal if, after start of the rich control, an output value of the ammonia detection device does not rise to a reference value before the air-fuel ratio detected by the air-fuel ratio detection device falls to a rich judged air-fuel ratio richer than a stoichiometric air-fuel ratio.

摘要： In a high pressure pump in a system for fuel injection in a combustion engine, determining whether a predetermined partial load operating condition prevails in the combustion engine, at which one single of several pump elements (10) in the high pressure pump is capable of alone delivering a fuel pressure requested in an accumulator tank (6), according to a first reference value, and to achieve a reproducible increase of the fuel pressure to a second reference value. If applicable, the high pressure pump's pump elements are controlled so that one single pump element alone delivers the fuel pressure in the accumulator tank according to the first reference value, whereupon this reference value is changed to the second reference value, and the actual development of the pressure in the accumulator tank as a function of time is determined, and compared with stored values of similar developments for the determination of information regarding the pump element's performance ability.

摘要： Internal combustion engine (1) has direct injection fuel injection valve (8) and port injection fuel injection valve (9). A requested fuel injection amount is calculated according to an engine operation condition. When the requested fuel injection amount is in first operation region (R1) in which the minimum fuel injection amount of direct injection fuel injection valve (8) is exceeded, a direct injection fuel injection valve (8) fuel injection amount is adjusted based on the requested fuel injection amount and a fixed amount, while maintaining a port injection fuel injection valve (9) fuel injection amount at the fixed amount. First operation region is at least a region in which the requested fuel injection amount exceeds the direct injection fuel injection valve minimum fuel injection amount. In first operation region, the port injection fuel injection valve fuel injection amount is fixed at the minimum fuel injection amount of port injection fuel injection valve.

摘要： A vehicle control apparatus that makes it possible to attempt fuel consumption improvement and exhaust gas reduction effectively without causing a sense of incompatibility in the driver is provided. When traveling following the preceding vehicle, kinetic energy required for an own vehicle in future is predicted on the basis of kinetic energy of the own vehicle, a velocity of a preceding vehicle, and a distance between the own vehicle and the preceding vehicle. It is determined whether there is kinetic energy enough for the own vehicle to be able to follow the preceding vehicle with inertial traveling, on the basis of the predicted kinetic energy and current kinetic energy. When it is determined that the kinetic energy is sufficient and the driving and traveling state of the own vehicle satisfies other traveling idling reduction conditions, control of stopping the engine is exercised.

摘要： In order to eliminate noise generated by misfiring when the rotational frequency rises to the operating rotational frequency immediately after a low-temperature startup, or when the rotational frequency rises to the operating rotational frequency from an idling rotational frequency in a low-temperature state, a fuel injection control device for an internal combustion engine is equipped with: a fuel injection device that is capable of multi-stage injection of fuel (accumulated in a common rail (6)) by means of injectors (2); a cooling water temperature sensor (26) serving as a water temperature detection means that detects the temperature of cooling water in the engine (1); an exhaust temperature sensor (24) serving as an exhaust temperature detection means that detects the exhaust temperature of the engine (1); and an engine control unit (13) serving as a control device. When the engine starts up and the cooling water temperature is equal to or greater than a prescribed water temperature (T) degrees, the control device executes a misfire prevention mode whereby a multi-stage injection is continued.
