摘要： PROBLEM TO BE SOLVED: To detect an abnormal part with a simple method when abnormality occurs in a fuel system. SOLUTION: An internal combustion engine is operated in a plurality of operational conditions with different discharge amount of a fuel pump per hour to detect the pressure difference between the fuel pressure supplied to a fuel injection valve and the pressure which should be pressurized with a fuel pump. When the detected pressure difference decreases as the fuel discharge amount per hour increases, it is determined that a fuel leakage has occurred downstream of the pump. Since the amount of the fuel leakage is almost constant per hour at the time of leak occurrence, the influence by the leakage becomes relatively smaller with a increase in the discharge amount of the pump, so that the leakage downstream of the pump can be detected. Thus, the maintenance or repair of the engine can be performed appropriately and simply. COPYRIGHT: (C)2004,JPO
摘要翻译：要解决的问题：当在燃料系统中发生异常时，以简单的方法检测异常部分。解决方案：内燃机在多个操作条件下操作，每小时燃料泵的排放量不同，以检测供应到燃料喷射阀的燃料压力与应当用燃油泵。当检测到的压力差随着每小时燃料排放量的增加而减小时，确定在泵的下游发生了燃料泄漏。由于泄漏时的燃料泄漏量几乎为每小时恒定，因此随着泵的排出量的增加，泄漏的影响变得相对较小，从而可以检测到泵下游的泄漏。因此，可以适当且简单地执行发动机的维护或维修。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To provide a start control device of an internal combustion engine capable of avoiding any defective start caused by vapor without unnecessarily operating a fuel pump. SOLUTION: An engine ECU stores a map specifying three zones of a high-temperature high-pressure zone (1), a low-temperature low-pressure zone (3), and an intermediate zone (2) therebetween according to the temperature and the pressure of a fuel, and the saturated vapor pressure of the fuel. When the start of an engine is requested (YES in S100), the engine ECU detects the temperature THW of an engine cooling water and the fuel pressure P (S200). If the detected values belong to the zone (2) (YES in S300), the engine ECU sets the pre-feed time T (S400), and executes a program including a step (S700) of executing the pre-feed until the fuel pressure P reaches or exceeds the desired fuel pressure threshold P (TH), and a step (S800) of starting the cranking when the fuel pressure P reaches or exceeds the fuel pressure threshold P (TH) (YES in S700).
