    摘要: An exhaust gas purifying apparatus for an internal-combustion engine, including a three-way catalyst, nitrogen oxide purifier that is disposed downstream of the three-way catalyst, an upstream oxygen sensor that is disposed between the three-way catalyst and the nitrogen oxide purifier, and a downstream oxygen sensor that is disposed downstream of the nitrogen oxide purifier. An abnormality determination criterion is set in accordance with the exhaust gas amount of the internal-combustion engine wherein the criterion is equivalent to a time period until the output of the downstream oxygen density sensor is read since the output of the upstream oxygen density sensor is changed to rich after the air-fuel ratio of the exhaust gas was over from lean to rich. Any abnormality of the nitrogen oxide purifier is determined when the output of the downstream oxygen density sensor has been changed to rich before the time period represented by the criterion elapses.

    摘要: A control device for a hybrid vehicle provided with an engine and a motor as driving sources, and a storage battery device which stores regenerative energy obtained by output from the engine or by regenerative operation of the motor during deceleration of the vehicle. The control device includes: a vehicle speed detection unit which detects speed of the vehicle; a deceleration fuel cut determination unit which determines whether supply of fuel to the engine is stopped during deceleration of the vehicle; and a brake detection unit which detects operation of a brake, wherein regenerative braking is stopped when operation of the brake is detected by the brake detection unit if the vehicle speed detected by the vehicle speed detection unit is lower than a predetermined speed and if it is determined by the deceleration fuel cut determination unit that the supply of fuel to the engine is not stopped.

    摘要: In order to prevent an occurrence of dieseling phenomenon, and to prevent engine rotation speed from decreasing during idle operation or the idle operation from being stopped, in step S111, it is determined whether the flag value of an idle stop flag F_IDLSTP is “1” or not. If it is determined that the determination result is “YES”, that is, if it is determined that the internal combustion engine body is stopped, 0% is set to a target purge control valve drive duty value PGCMD (step S105), and 0 is set to the target purge flow rate QPGC (step S106). If it is determined that the determination result is “NO”, that is, when the internal combustion engine body is in operation, PGCMD calculation processing is executed (step S112). While the internal combustion engine body is stopped, execution of purge is stopped, thereby an occurrence of a dieseling phenomenon which is caused because the flow rate of the air flowing into the internal combustion engine body increases and the air is compressed, is prevented, thereby suppressing vibration from occurring in the internal combustion engine body.
