Abstract
An apparatus controlling a fuel injection quantity at the time of starting a Diesel engine and a method are disclosed. The apparatus and method detect a water temperature at the time of starting the Diesel engine, detect an engine speed at the time of starting the Diesel engine, set a starting fuel injection quantity based on the water temperature at the time of starting the Diesel engine and the engine speed at the time of starting the Diesel engine, detect a line pressure of an automatic transmission mounted to the Diesel engine, and correct the starting fuel injection quantity based on the line pressure of the automatic transmission.
Claims9
An apparatus controlling a fuel injection quantity at the time of starting a Diesel engine, comprising:
- a water temperature sensor sensing a water temperature of said Diesel engine;
- an engine speed sensor sensing an engine speed of said Diesel engine;
- a starting fuel injection quantity set section setting a starting fuel injection quantity based on said water temperature at the time of starting said Diesel engine sensed by said water temperature sensor and said engine speed at the time of starting said Diesel engine sensed by said engine speed sensor;
- a line pressure sensor sensing a line pressure of an automatic transmission provided to said Diesel engine;
- and
- a starting fuel injection quantity correction section correcting said starting fuel injection quantity set by said starting fuel injection quantity set section based on said line pressure of said automatic transmission detected by said line pressure sensor.
