    摘要： PURPOSE: A method for controlling a fuel injection in a diesel vehicle is provided to prevent power of the diesel vehicle from being lowered due to reduction of fuel by effectively controlling the amount of fuel when the performance of the diesel vehicle is lowered. CONSTITUTION: A fuel injection is controlled through a smoke map having mapping parameters, which are set based on fuel injection in each gear transmission step(S312). Then, a theoretical air/fuel ratio of a diesel vehicle is compared with a real air/fuel ratio of the diesel vehicle(S316). If the real air/fuel ratio of the diesel vehicle is a lean state as compared with the theoretical air/fuel ratio of the diesel vehicle, a minimum value of fuel for driving the diesel vehicle is compared with a real value of fuel for driving the diesel vehicle(S318). If the real value of fuel is larger than the minimum value of fuel, the fuel injection is controlled based on the real value of fuel(S320).

    摘要： PURPOSE: A function to adjust engine torque reflecting driving road condition and driver's taste is applied to reduce air fuel ratio in a diesel engine. CONSTITUTION: A device for controlling fuel injection comprises a driving state detecting member(100), an engine controller(200), and a driving member(300). The engine controller outputs control signal to the driving state detecting member, receives acceleration pedal position, a kickdown switch state, a setting switch and an engine rpm to calculate engine load. If the acceleration pedal position, engine load, and engine rpm are over predetermined values, when the kickdown switch and the setting switch are not 'off', a multi engine torque map is applied to output a control signal for fuel injection. When the kickdown switch is off, an alarming signal for disorder of the kickdown switch is outputted.

    摘要： PURPOSE: A method for accurately controlling injection timing and time by compensating the response delay time of fuel injection actuators of cylinders and counting the output signals of phase control loops of the cylinders. CONSTITUTION: An injection timing and time control method comprises the steps of: detecting the cylinder reference signals and rpm inputted from a sensor by using an interrupt and a timer of a microprocessor; discriminating the cylinder in a reference discriminating interrupt routine using the detected cylinder reference signal; and compensating the fuel injector actuator response delay time of the corresponding cylinder by counting the rpm signal after dividing frequency in a phase control loop with synchronization to a cycle of rpm signals. By independently compensating the response delay time of respective cylinders, fuel injection timing and time are controlled accurately.
