摘要： An abnormality detection apparatus for detecting an abnormality of an oil level sensor having lower and upper oil level detectors includes: a recording portion that records the output of the upper oil level detector before the internal combustion engine is started; and a determining portion that determines that the upper oil level detector has an abnormality if the output of the lower oil level detector is indicating, after the start of the internal combustion engine, that the oil level is higher than the first reference oil level while the output of the upper oil level detector recorded by the recording portion is indicating that the oil level was lower than the second reference oil level before the start of the internal combustion engine.

摘要： A diesel engine includes: a PM filter provided in its exhaust passage; a fuel injection valve for performing post fuel injection in a cylinder of an engine body in addition to primary fuel injection, in order to supply fuel to the PM filter, to maintain its purification performance; an oil level sensor for detecting a degree of dilution of engine oil; and a first indicator lamp that is turned on to indicate that the engine oil needs to be changed when the degree of dilution of engine oil detected by the oil level sensor is equal to or greater than an allowable level. The vehicle diesel engine overrides the prohibition of the post fuel injection until a distance traveled by the vehicle after the indicator lamp is turned on reaches a predetermined distance.
