Electronic engine control system (EECS) is through the engine's ignition, fuel injection, air/fuel ratio, emissions of electronic control, the engine in the best working conditions, so as to improve vehicle performance, the purpose of saving energy and reducing emissions.
1. Electronic ignition (ESA)
Electronic ignition device by microcomputer, sensors, actuators and interfaces, and so on. The engine parameters according to the sensor of the device carry out operations, judging, and then the ignition time is regulated, can keep the engine at different speeds and air condition, guaranteed to work under optimal ignition advance angle and output maximum power and torque of the engine, reduce fuel consumption and emissions, save fuel, reduce air pollution.
2. Electronic fuel injection (EFI)
Fuel injection control device because of its superior performance and gradually replaced the mechanical and electro-mechanical hybrid type fuel injection system. Dang engine work Shi, the device according to the sensor measuring have of air flow, and intake temperature, and engine speed and the work temperature, parameter, by advance prepared of program for operation Hou and memory in the advance storage of best workers condition Shi of for oil control parameter for compared and judge, timely adjustment for oil volume, guarantee engine always in best State Xia work, makes its in output must power of conditions Xia, engine of integrated can get improve.
3. Exhaust gas recirculation control (EGR)
EGR control system is used to reduce the emission of nitrogen oxide emissions in an efficient measures. Its main component is the digital EGR valve, independently of the amount of exhaust gas is recirculated to the engine for accurate control.
