1. electronic ignition device (ESA)

The electronic ignition device is composed of microprocessor, sensor and its interface, actuator, etc. Automobile electronic controller this 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 under the optimal ignition advance angle under different rotating speeds and air intake, so that the engine can output the maximum power and torque, reduce fuel consumption and emissions, save fuel and reduce air pollution.

2. electronic fuel injection (EFI)

The controlled fuel injection device has gradually replaced the mechanical or electromechanical hybrid fuel injection system because of its superior performance. When the engine is working, the device calculates according to the parameters measured by each sensor, such as air flow, intake air temperature, engine speed and operating temperature, compares and judges with the fuel supply control parameters under the best working conditions stored in the memory in advance, and timely adjusts the fuel supply to ensure that the engine always works in the best state, so that it can output a certain power, The comprehensive performance of the engine is improved.
