Abstract:
An engine fuel injection control device for performing pilot injection and main injection, said control device being one whereby a base pilot injection quantity is determined on the basis of rotational engine speed (NE), a total fuel injection quantity (Q), and a temperature of engine cooling water (TW), and whereby the base pilot injection quantity is set such that the lower the temperature of the engine cooling water is, the more the base pilot injection quantity is, and the higher the temperature of the engine cooling water is, the less the base pilot injection quantity is, and whereby when an ambient temperature is lower than a prescribed temperature, correction of the base pilot injection quantity is performed so as to increase the pilot injection quantity, and whereby when the temperature of the engine cooling water is higher than a first prescribed temperature on a high-temperature side, the correction of the base pilot injection quantity on the basis of the ambient temperature is not performed.
