摘要： A vehicle control device applied to a vehicle including an internal combustion engine and an electrically heated catalyst which is warmed by applying a current, and includes a catalyst carrier supporting a catalyst and a carrier retention unit that retains the catalyst carrier and has an electrical insulation property. The vehicle control device includes an insulation resistance determination unit which determines whether or not an insulation resistance of the carrier retention unit decreases to a value equal to or lower than a predetermined value, and an applying current prohibition unit which prohibits applying the current to the electrically heated catalyst when the insulation resistance determination unit determines that the insulation resistance decreases to the value equal to or lower than the predetermined value. Therefore, it is possible to appropriately control of applying the current to the electrically heated catalyst based on the insulation property of the carrier retention unit, and hence it becomes possible to appropriately prevent an electrical leak of the electrically heated catalyst.

摘要： A fuel vapor feed controlling apparatus of a lean burn internal combustion engine suppresses either one of a rich misfire or a surge when fuel vapor is fed into the engine. A purge controlling unit controls an amount of fuel vapor fed from a fuel reservoir to the engine in response to an operational condition of the engine. A first compensation unit compensates the amount of fuel vapor such that an engine revolution speed of the engine may be identical with a target revolution speed. The purge controlling unit performs a purge control based on a compensation value compensated by the first compensation unit.

摘要： In an internal combustion engine in which a throttle valve is substantially fully opened in most of the operating regions such as an in-cylinder injection type internal combustion engine, a technique is provided capable of effectively processing an evaporative fuel while stabilizing a combustion state of the internal combustion engine even in the case that an amount of evaporative fuel generated in a fuel tank or the like is increased. To achieve this technique, a purge amount of evaporative fuel is increased by increasing a differential pressure between an upstream portion and a downstream portion of a purge passage, and the differential pressure between an upstream portion and a downstream portion of a purge passage, and the differential pressure is adjusted in accordance with the combustion state of the internal combustion engine at that time, thereby making it possible to purge the maximum amount of evaporative fuel within a range in which the combustion state is not unstabilized.

摘要： A diagnostic apparatus for a fuel vapor treating apparatus closes a breather to shut a purge system valve during purge. While further continuing the purge, the apparatus detects the purge flow thereby caused and a pressure change occurring in the purge system. Based on the purge flow and the pressure change, the space volume in the purge system is estimated. By comparing the estimated space volume and the actual space volume in the purge system, the apparatus determines whether there is a failure or fault in the purge system.
