Diesel engine fuel injection control device and fuel injection control method

摘要

An arrangement for controlling diesel engine fuel injection including a first sensor that detects engine temperature and a second sensor that detects outside air temperature. An associated electronic control unit adjusts the amount of advance of pilot injection timing relative to main injection timing based on the difference between the engine temperature and the outside air temperature. Since the amount of advance is determined based on the engine temperature and the outside air temperature, the warmup state of an engine is considered in determining the amount of advance. This means that differences in the temperature inside an engine cylinder are considered. Accordingly, it is possible to obtain an optimum amount of advance.
