摘要： A leak diagnostic apparatus is provided for an evaporative emission control system that purges fuel vapor from an inside of a fuel tank to an intake passage of an internal combustion engine. The leak diagnostic apparatus is basically provided with a pressure detecting device and a leak determining device. The pressure detecting device is configured and arranged to detect a pressure inside the evaporative emission control system, which includes the fuel tank. The leak determining device sets a leak determination threshold value in accordance with a deformation amount of the fuel tank, and determines if a leak exists by comparing the pressure inside the evaporative emission control system while the evaporative emission control system is sealed to the leak determination threshold value.

摘要： A leak detecting apparatus includes a canister adsorbing a fuel vapor evaporated in a fuel tank, a measure passage, a pump connected with the canister through the measure passage, and a pressure senor detecting a pressure in the measure passage. The pump depressurizes the measure passage, the canister, and the fuel tank so that a leakage of the fuel vapor is detected. When a blow-by of the fuel vapor is arisen, the pump is stopped to forcibly terminate a depressurization.

摘要： An ECU computes a transit time from a time when the fuel vapor passes the purge valve right after the purge valve is opened until a time when the fuel vapor reaches a vicinity of the fuel injector. Further more, the ECU computes a fuel vapor concentration at the vicinity of the fuel injector after the transit time has elapsed based on a first-order lag curve which is defined by a maximum variation of the fuel vapor concentration and a time constant. Correcting the fuel injection quantity according to the fuel vapor concentration at the vicinity of the injector restricts a disturbance of air-fuel ratio at a time of starting purge process.

摘要： A fuel vapor processing apparatus includes a canister, a purge passage, a detection passage including an atmosphere passage and a restrictor, a passage changing valve for changing the connection passage of the detection passage between the purge passage and the atmosphere passage, a pump connecting with the detection passage on the opposite side of the passage changing valve across the restrictor, a pressure sensor for detecting a pressure between the restrictor and the pump, and an ECU for computing the concentration of fuel vapor. When the passage changing valve causes the purge passage to connect with the detection passage and the pump reduces pressure in the detection passage to pass the air-fuel mixture through the restrictor, the pressure sensor detects the pressure during a detection period of time that elapses after the air-fuel mixture passes through the restrictor until the air-fuel mixture reaches the pump.

摘要： A pump generates a gas flow within a measurement passage having an orifice. A differential pressure sensor detects a pressure difference between both ends of the orifice. Switching valves are disposed in the measurement passage to create a first concentration measurement state in which the measurement passage is opened at both ends thereof and the gas flowing through the measurement passage is the atmosphere, and a second concentration measurement state in which the measurement passage is in communication at both ends thereof with a canister and the gas flowing through the measurement passage is a fuel vapor-containing air-fuel mixture provided from the canister. An ECU calculates a fuel vapor concentration by based on a pressure difference detected in the first concentration measurement state and a pressure difference detected in the second concentration measurement state.
