<p>Experiment shows that a diesel engine discharges more smoke at a lower rate of increase of an engine rotation speed. Reducing an amount of fuel to inject into the engine when the rate of increase of the engine rotation speed is slow can prevent smoke generation. To be more specific, a controller (1) computes the rate of increase of the engine rotation speed by using signals from sensors that detect a vehicle condition. The controller (1) contains maps that indicate a correction coefficient corresponding to the rate of increase of the engine rotation speed. The controller (1) calculates the amount of fuel to inject based on the correction coefficient. Using the calculated amount of fuel, the smoke discharge from the diesel engine is suppressed. <IMAGE></p> |
