The engine electronic control system (EECS) electronically controls the engine ignition, fuel injection, air-to-fuel ratio, exhaust gas, etc., so that the engine works under the best working conditions, so as to improve its vehicle performance, save energy, The purpose of reducing exhaust emissions.
The electronically controlled ignition device is composed of a microprocessor, a sensor and its interface, and an actuator. The device calculates and judges according to the engine parameters measured by the sensor, and then adjusts the ignition time, so that the engine can work at the best ignition advance angle under the conditions of different speeds and intake air volumes, so that the engine output can be maximized. Power and torque, reduce fuel consumption and emissions, save fuel and reduce air pollution.
Due to its superior performance, electronically controlled fuel injection devices have gradually replaced mechanical or electromechanical hybrid fuel injection systems. When the engine is working, the device calculates according to the parameters such as air flow, intake air temperature, engine speed and operating temperature measured by each sensor, and calculates the oil supply at the best working condition pre-stored in the memory. The control parameters are compared and judged, and the fuel supply is adjusted in a timely manner to ensure that the engine is always working in the best state, so that the overall performance of the engine can be improved under the condition of outputting a certain power.
