摘要： An exhaust gas purifying device of the invention comprises an exhaust gas purifying catalyst (20) disposed in an exhaust system, a fuel adding device (28) for adding fuel to the exhaust gas purifying catalyst (20) as a reducing agent, a fuel supplying source (6) for supplying the fuel adding device (28) with fuel, an emergency shut-off valve (31) disposed in a fuel supplying passage (29) that connects the fuel supplying source (6) to the fuel adding device (28), and a shut-off valve position detecting means for detecting that the emergency shut-off valve (31) is closed. If an upstream fuel pressure applied to the emergency shut-off valve (31) becomes higher than a downstream fuel pressure applied to the emergency shut-off valve (31), the emergency shut-off valve (31) is controlled so as to be prevented from being opened. If the exhaust air-fuel ratio does not shift to the rich side despite the issuance of an instruction to add fuel at this moment, it is possible to detect that fuel leakage has occurred downstream of the emergency shut-off valve (31).

摘要： Provided is a fuel injection control device which secures stability of a combustion state, and simultaneously optimizes exhaust gas characteristics for a diesel engine with a low compression ratio. The fuel injection control device for a diesel engine with a low compression ratio refers to a control map having four predetermined areas determined by a operation state of the engine, and then, selectively employs different types of fuel injection patterns accompanied by as many as twice of pilot injections. The fuel injection control device maximizes the number of conducting the pilot injections so as to prioritize restraining the combustion noise and optimizing exhaust gas characteristics when the operation states of an engine is in an area II where freedom of setting ranges for the timing of conducting the pilot injection and the main injection, and the interval of conducting the individual injections is relatively high (a low load/low rotation speed area).
