    摘要： A start control apparatus for an internal combustion engine which guarantees excellent startability regardless of the nature of the fuel used. In addition, a fuel nature determining apparatus designed to prevent mistakes in the determining of the nature of the fuel. When conditions for beginning the starting of an internal combustion engine have been established, normal start control is performed in order to start the internal combustion engine. After the starting of the internal combustion engine has begun using the normal start control, if the starting is completed within a predetermined length of time, a determination is made that the fuel supplied to the internal combustion engine is of a light nature. If, however, the starting is not completed within a predetermined length of time, a determination is made that the fuel supplied to the internal combustion engine is of a heavy nature. In this case, after a predetermined length of time has elapsed, heavy fuel start control is performed in place of the normal start control so that the starting of the internal combustion engine will be quickly completed. According to the above method, the nature of the fuel is detected before the starting of the internal combustion engine is completed and, when the fuel is of a heavy nature, the start control can be altered to control which corresponds to the nature of the fuel.

    摘要翻译： 一种用于内燃机的起动控制装置，其与所使用的燃料的性质无关地保证了优异的起动性。 另外，燃料性质确定装置被设计成防止在确定燃料性质方面的错误。 当内燃机起动的条件已经建立时，为启动内燃机，执行正常的启动控制。 在内燃机的启动已经开始使用正常启动控制之后，如果在预定时间内完成启动，则确定供给到内燃机的燃料是轻质的。 然而，如果在预定时间内没有完成启动，则确定供给到内燃机的燃料是重的。 在这种情况下，经过预定时间后，进行重型燃料起动控制来代替普通启动控制，使内燃机的启动快速完成。 根据上述方法，在内燃机启动完成之前检测燃料的性质，并且当燃料性质很重时，起动控制可以改变以控制与燃料性质对应 。

    摘要： Even under satisfaction of an EGR condition during operation of an engine, when it is determined that the cooling power of a cooling system is less than a preset reference power, based on a cooling water temperature and an outside air temperature, an EGR valve is controlled to prohibit circulation of exhaust into a gas inlet line. The reference power is set as a criterion of assuring a minimum required power for cooling down the engine even when the EGR is performed during the operation of the engine. This arrangement effectively prevents a decrease in cooling power of the cooling system. When it is determined that the cooling power of the cooling system is not less than the preset reference power, the EGR valve is controlled to allow circulation of the exhaust into the gas inlet line with a target EGR amount calculated from an intake air amount. This arrangement ensures the appropriate operation of the engine.
