1. Electronically controlled ignition device (ESA)
The electronically controlled ignition device consists of a microprocessor, sensors and their interfaces, actuators, etc. This device of the automotive electronic controller performs calculations and judgments based on the engine parameters measured by the sensor, and then adjusts the ignition timing. This device can ensure that the engine operates at an optimal ignition advance angle under conditions such as different speeds and air intakes, so that The engine outputs maximum power and torque, reduces fuel consumption and emissions, saves fuel and reduces air pollution.
2. Electronic fuel injection (EFI)
controlled fuel injection devices have gradually replaced mechanical or electromechanical hybrid fuel injection systems because of their superior performance. When the engine is running, the device calculates the fuel supply control parameters according to the pre-programmed program based on the air flow, intake air temperature, engine speed and operating temperature measured by each sensor, and then compares the fuel supply control parameters with the working conditions pre-stored in the memory. Compare and judge, and adjust the fuel supply amount in a timely manner to ensure that the engine always works in an optimal state, so that the overall performance of the engine can be improved under the condition of outputting a certain power.
