摘要： A failure test apparatus for a fuel-vapor purging system for adsorbing fuel vapor in a fuel tank into a canister and for purging fuel to an intake system of an internal combustion engine as needed. The purging system has at least one valve. A first test unit provides a differential pressure between the inside and the outside of the fuel-vapor purging system, measures the internal pressure with the fuel-vapor purging system in an airtight condition, and determines whether a leak exists in the fuel-vapor purging system from the behavior of the internal pressure. The test by the first test unit involves a differential-pressure forming process of creating a differential pressure between the inside and the outside of the fuel-vapor purging system, a sealing process of making the fuel-vapor purging system airtight when the differential pressure exists, and a differential-pressure releasing process for releasing the differential pressure. In association with one or more of the processes, a second test unit measures the internal pressure of the fuel-vapor purging system to detect a failure in any valve actuated in one of the processes based on the behavior of the internal pressure.

摘要： In a diagnostic apparatus and method for a fuel vapor purge system in which fuel vapor generated in a fuel tank trapped in a chamber is purged into an intake passage of an internal combustion engine through a purge path, a first change in a pressure of the purge path is measured after creating a pressure difference between the inside and outside of the purge path and sealing the purge path, and a second change in pressure that varies with an amount of fuel vapor generated in the fuel tank is measured while the purge path is sealed for a first period of time after an atmospheric pressure is introduced into the purge path. Then, it is determined whether leakage is present in the purge path, based on the first change and the second change in the pressure of the purge path. Before the measurement of the first and second pressure changes, a third change in the pressure that varies with an amount of fuel vapor generated in the fuel tank is measured while the purge path is sealed for a second period of time after the atmospheric pressure is introduced into the purge path before the pressure difference is created. The leakage diagnosis is inhibited when the third change in the internal pressure is greater than a predetermined value, and the leakage diagnosis is permitted when the third change is equal to or less than the predetermined value.

摘要： A fuel vapor purge system includes a fuel tank, a canister, and an evaporation route, and purges fuel vapor collected in the canister into an intake passage of an internal combustion engine. A failure diagnosis apparatus of the fuel vapor purge system includes a controller having a pressure difference applying unit for applying a pressure difference between the evaporation route and outside air. The controller also detects a level of an influence of the fuel vapor generated in the fuel tank on failure determination of the evaporation route, and detects both a pressure state obtained when the pressure difference applying unit communicates with a reference orifice communicating with the outside air and a pressure state obtained when the pressure difference applying unit communicates with the evaporation route. The failure diagnosis apparatus determines whether there is a failure in the evaporation route in view of the level of the influence by comparing the detected pressure states with each other.

摘要： A variable valve timing apparatus for an internal combustion engine, includes an actuator (15) that operates a first variable valve timing mechanism; a detecting portion (35) that detects a driving position of the actuator (15); and a control portion (21) that executes an initialization process only when a preset execution condition is satisfied. In the initialization process, the control portion drives the actuator (15) to one end of a driving range and sets the driving position detected in this state as an initial value, and then drives the actuator (15) to an opposite end of the driving range and reflects an offset amount of the driving position detected in that state with respect to an optimum value in the driving position to compensate for the offset amount. The execution condition includes a condition that an increase amount in acceleration required of the internal combustion engine (1) be equal to or greater than a preset first determining value.

摘要： A suction pump introduces negative pressure into a reference-pressure-detecting portion. A driving voltage V of the suction pump is adjusted in such a manner that pressure Pr in the reference-pressure-detecting portion is within a target pressure range. When the pressure Pr is brought into the target pressure range, the driving voltage V of the suction pump is stored as a first driving voltage V1 and the pressure Pr is stored as a reference pressure Pr. When pressure detection and leak detection process are conducted, the suction pump is driven at the first driving voltage V1 to introduce the negative pressure. The computer compares the pressure Pr with a leak determination value to determine whether a leak exists.

摘要： A malfunction determining apparatus of an exhaust gas recirculation system performs an accurate determination of malfunctioning of an EGR valve based on an amount of change in the actual degree of opening of the EGR valve. The EGR valve is provided between an exhaust passage and an intake passage of an internal combustion engine of a vehicle. An actual valve opening degree detector detects an actual valve opening degree of the EGR valve. A target valve opening degree calculator calculates a target valve opening degree of the EGR valve. A malfunction determining part calculates an amount of change in the actual valve opening degree when an amount of change in the target valve opening degree is equal to or greater than a predetermined value so as to determine an occurrence of malfunction in the exhaust gas recirculation system based on a comparison between the amount of change in the actual valve opening degree and a second predetermined value.
