Abstract: PURPOSE: A method for controlling an injection time of a fuel injection pump is provided to improve an engine performance by stably operating an engine through stably injecting fuel regardless of the sudden variation of cooling water temperature. CONSTITUTION: An ECU detects an engine R.P.M, accelerator pedal voltage, and a cooling water temperature(S100). After reading map data in normal temperature and low temperature(S110), it is determined whether the cooling water temperature is higher than or identical to a reference temperature(S120). If the cooling water temperature is higher than or identical to the reference temperature, map data of the normal temperature is outputted, thereby controlling a fuel injection time(S150). If the cooling water temperature is lower than a reference temperature, it is determined whether the cooling water temperature is identical to or lower than a determining temperature(S160). If the cooling water temperature is identical to or lower than the determining temperature, map data of the lower temperature is outputted(S170), thereby controlling the fuel injection time.

Abstract: PURPOSE: A compensatory control method for target injection timing is provided to stably operate a vehicle without shortage of injection time and torque fluctuation due to change of a mode. CONSTITUTION: A target injection timing compensation is controlled by the following steps. Fuzzy operation is performed by calculating basic target injection time, target air amount and target injection time(30-31). Target injection time is compared to a minimum reference injection time during fuzzy operation(32-33). The performance of lean operation is decided. If the target injection time is less than the minimum reference injection time or an engine is in a lean operation mode, the target injection time is corrected. The corrected target injection time is reduced according to the present air amount. Operation is continued while purge amount is maintained by the reduced air amount. By increasing or decreasing target injection time according to injection amount and air amount, an engine is operated stably.
