摘要： In a leak diagnostic system of an evaporative emission control system for an internal combustion system, which utilizes a change in internal pressure in a predetermined fluid-flow passage ranging from a fuel tank via a canister to a purge control valve, in addition to a relative-pressure sensor for sensing the internal pressure, an atmospheric-pressure sensor is provided for sensing atmospheric pressure. The leak diagnostic system includes a control module which samples the pressure in the predetermined fluid-flow passage as a first fluid-flow passage pressure at a first sampling time when a predetermined decompressing operation is completed, and samples the pressure in the predetermined fluid-flow passage as a second fluid-flow passage pressure at a second sampling time when a predetermined time interval has been elapsed from the first sampling time. The leak diagnostic system makes a leak diagnosis by comparing the pressure differential between the first and second fluid-flow passage pressures with a predetermined leak criterion. The control module compensates for the pressure differential by the atmospheric-pressure change occurring for a time interval from the first sampling time to the second sampling time.

摘要： At the time of a stop of an engine, a diagnostic control unit shuts off a purge line with a purge control valve and an atmospheric port of a canister with a drain cut valve, and thereby holds an evaporative emission control circuit inclusive of a fuel tank and the canister in a state of a closed space during an off period of the engine. At the time of a next start of the engine, the diagnostic control unit measures a pressure in the closed circuit with a pressure sensor and checks a pressure decrease due to condensation of fuel vapors in the closed circuit to determine the existence or nonexistence of leakage.
