Although the engines of mid- to high-end cars produced in my country basically use fuel electronic injection technology, the components of the electronic injection system have been basically Those with supporting R&D capabilities and production capabilities but without independent intellectual property rights for EFI engines are all imported foreign EFI engine production lines or EFI systems. Idle speed control: When the engine is running, the air conditioner compressor is working, the transmission is in gear, the generator load is increasing, etc., the idle speed control valve is controlled so that the engine can run at the optimal idle speed.
The main emission control control projects include: exhaust gas recirculation control, oxygen sensor and three-way catalytic open-loop and closed-loop control, secondary air injection control, activated carbon canister solenoid valve control, etc. Warning and prompt control Various prompts and warning devices display the working status of the control system and send out warning signals if the control system fails.
Sensor fault pre-diagnosis reference system When the main engine detects a sensor or line failure, it will follow the set value provided by the main pre-program so that the engine can still keep running but the performance will be reduced. Main failure backup redundant system When the main failure occurs, the backup redundant system will automatically activate the backup redundant system to put the engine into a forced running state so that the driver can drive it for repair.
The engine's intelligent electronic control technology demonstrates its use of buses. Chengdu Panfeng Technology said: Intelligent fuel injection control mainly includes fuel injection volume, injection timing, fuel supply cutoff and fuel pump control. Due to the use of intelligent design to solve the deficiencies of the fixed control algorithm, it can effectively save fuel and help improve overall performance. Intake control mainly includes power valve and swirl valve control, which can effectively improve and increase the output torque and power of the engine.
The boost control controls the pressure relief solenoid valve according to the intake pressure signal detected by the intake pressure sensor to control the exhaust passage switching valve to change the direction of the exhaust passage to control the exhaust gas turbocharger to enter the working or stopping state. Electronic ignition control The control of the ignition device mainly includes ignition advance angle control, power-on time (closure angle) and constant current control, knock control, etc.
