摘要： An exhaust leak detecting apparatus includes an exhaust pressure sensor to detect the exhaust pressure in a portion of an exhaust passage that allows exhaust gas discharged from an engine to flow therethrough, the portion being located at a position upstream of a catalyst for purifying exhaust gas, and an exhaust leak determining part to determine that exhaust gas is leaking or may leak from the exhaust passage upstream of the catalyst and generate a warning when the exhaust pressure detected by the exhaust pressure sensor falls outside a predetermined range.

摘要： A fuel vapor processing apparatus may include a canister, a closing valve provided in a vapor passage connecting the canister and the fuel tank, an actuator coupled to the movable valve member, and a control device coupled to the actuator. The control device may perform a learning control, in which a valve opening start position is learned based on a stroke distance of the movable valve member, which is given at the time when an internal pressure of the fuel tank is reduced by a predetermined pressure value while the moving distance of the movable valve member is changed such that (a) the movable valve member moves from the reference position to a learning start position at a first speed in a valve opening direction and (b) the movable valve member moves further from the learning start position at a second speed in the valve opening direction.

摘要： A leakage detector for a fuel vapor treatment device includes a control unit. The control unit shifts a purge control valve and a shutoff valve to a first state with the purge control valve is an opened position and the shutoff valve in a closed position, and then shifts the purge control valve and the shutoff valve to a second state with the purge control valve is a closed position and the shutoff valve in a closed position. The control unit compares a first purge passage pressure acquired from the purge passage pressure detector when the purge control valve and the shutoff valve were shifted to the second state with a second purge passage pressure acquired from the purge passage pressure detector after a lapse of a first waiting time after being shifting to the second state. This comparison is used to determine leakage in the purge passage.

摘要： A vaporized fuel processing apparatus has a fuel tank, a canister configured to adsorb vaporized fuel and connected to an internal combustion engine, a vapor path connecting the fuel tank to the canister, a closing valve having a stepping motor and configured to open and close the vapor path, and an electric control unit configured to cause the closing valve to an initial position in order to initialize the closing valve. The electric control unit is configured to determine whether it is in a predetermined initialization permission time when the initialization of the closing valve does not adversely affect running of the internal combustion engine. When it is determined that it is in the predetermined initialization permission time, the electric control unit is configured to output signals to start the initialization of the closing valve.

摘要： In a method of controlling a brake system, a basic control to operate an electric vacuum pump is performed when a booster internal pressure, i.e., an actual pressure of a negative pressure chamber of a brake booster, is larger than a target booster internal pressure, i.e., a target pressure in the negative pressure chamber. The electric vacuum pump is not operated under a predetermined condition even when the booster internal pressure is larger than the target booster internal pressure.
