摘要： A fuel vapor purge system is configured to execute a highly accurate leak diagnosis with respect to a fuel vapor leak. After the engine is stopped, the temperature of the fuel vapor rises temporarily and then decreases until it reaches the outside ambient temperature. During this period, the purge line is closed off and a minimum value reached by the purge line pressure is detected. The difference between the minimum value of the purge line pressure and the atmospheric pressure is compared to a threshold value. The purge system is diagnosed as “normal” if the difference is equal to or larger than the threshold value and a “leaking” if the difference is less than the threshold value.

摘要： An exhaust gas recirculation device for an internal combustion engine having a supercharger has an intake air passage that intakes intake air for the internal combustion engine, an exhaust passage that carries away exhaust air from the internal combustion engine, an exhaust gas recirculation passage connected to the intake air passage, and an exhaust gas recirculation valve interposed within the exhaust gas recirculation passage. The exhaust gas recirculation passage recirculates a part of the exhaust gas based on an openness of the exhaust gas recirculation valve to control an amount of exhaust recirculation introduced into the intake air passage. A first end of the exhaust gas recirculation passage is connected to the intake air passage upstream of a compressor of the supercharger. A second end of the exhaust gas recirculation passage is connected to the exhaust passage downstream of a turbine of the supercharger.
