KR940002485A - Automatic idle-up control of the engine and its realization method - Google Patents

Abstract

By detecting the state of the purified engine using the coolant temperature of the engine to ensure accurate warm-up operation automatically, it saves fuel, prevents trouble caused by excessive operation of the engine, and warms-up operation automatically. To reduce the harmful gas generated by the engine speed which rises sharply by detecting the operation of the acceleration pedal continuing by the driver after being switched to the idle state of the engine; A controller for automatically adjusting the idle of the engine, a plurality of sensors connected to the controller to detect a change according to a situation, and converting and outputting an electrical signal; Automatic idle-up control device of the engine comprising an actuator control unit for controlling the operation of the control valve that can adjust the amount, and a fuel injection pump unit connected to the actuator control unit to adjust the amount of fuel injected into the engine by the operation of the actuator And a method for realizing the same.

Claims (2)

A controller for automatically adjusting idle of the engine; A plurality of detectors connected to the controller for detecting a change according to a situation and converting and outputting an electrical signal; An actuator controller connected to the controller and controlling an operation of a control valve capable of adjusting an amount of fuel introduced into an engine; Automatic idle-up control device of the engine consisting of a fuel injection pump connected to the actuator control unit for controlling the amount of fuel injected into the engine by the operation of the actuator. When the algorithm starts, it detects the speed of the car and terminates the algorithm if the speed of the car is not “0”. If the speed of the car is “0”, it detects the temperature of the engine coolant. By controlling the actuator, the amount of fuel flowing into the engine is increased to accelerate the warm-up operation. When the coolant temperature of the engine is higher than the set temperature, the engine is kept idle and the engine speed is set by detecting the engine speed. When the engine speed is greater than the set speed due to the operation of the accelerator pedal by the driver, the engine speed is increased by controlling the actuator's operation to increase the engine speed by setting the engine speed. If it is smaller than the number, the engine idles and detects the speed of the car. If the actuator is operated to increase the engine speed, it starts counting the operating time of the actuator.If it is longer than the set time, the operation of the actuator to increase the engine speed is stopped. After determining whether the signal corresponding to the vehicle speed is input, stop the operation of increasing the engine speed when the vehicle speed signal is detected, and finish the algorithm if the vehicle speed signal is not input, and continue to increase the engine speed. A method for controlling the engine's automatic idle-up, which consists of a method of counteracting the actuator's operating time and automatically idling the engine at a constant speed when the set time is reached. ※ Note: The disclosure is based on the initial application.
