The connector is an important component in the automotive engine control system. It is responsible for controlling the work of the automotive fuel injector.
The connector transmits the signal provided by the engine control system to the fuel injector by connecting the power supply and control signal, thereby controlling the injection amount and injection timing of fuel. The working principle of the connector can be briefly described as the following steps:
First, the engine control system calculates the amount of fuel that needs to be injected based on current operating conditions and driving needs, and sends this information to the connector. This is usually done via an ECU (Electronic Control Unit).
Next, after the connector receives the control signal, it converts it into voltage and current suitable for use by the injector. This process is completed through electronic components inside the connector, such as resistors and chips. The connector then delivers power and control signals to the injector through the contact strips. The contact piece is a key component of the connector, which plays a role in connecting and disconnecting circuits. When the control signal arrives, the contact piece will come into contact with the electrode of the fuel injector, completing the circuit closure, and the fuel injector can inject fuel. When the control signal stops, the contact piece will separate from the electrode of the fuel injector, cutting off the circuit and stopping the injection.
Finally, the connector also needs to have certain waterproof and dustproof properties to ensure its stability and reliability in the automotive working environment. This is usually achieved through the choice of the connector’s sealing rubber ring and housing material. The reliability of connectors has an important impact on the power performance and fuel economy of automobiles. If the connector fails or works unstable, it will lead to inaccurate fuel injection volume, which will affect the engine’s efficiency and fuel consumption. Therefore, keeping the connector in good working condition and checking it regularly is one of the important measures to ensure the normal operation of the car.
To sum up, the connector connects the power and control signals, converts the signals provided by the engine control system into voltage and current suitable for the injector, and transmits the power and control signals to the injector through the contact piece, thereby accurately controlling the fuel. injection volume and injection timing. The reliability of the connector has an important impact on the vehicle’s power performance and fuel economy, so it requires regular inspection and maintenance.
