Engine wiring harness is an important part of the car, it is the electrical wiring harness connecting the engine and the vehicle electrical system. Engine wiring harnesses typically consist of multiple wires, connectors, insulating bushings, and other parts. It transmits power and signals to control the operation of the engine and monitor the state of the engine. The quality and stability of the engine harness have an important impact on the performance and safety of the vehicle.

The main functions of the engine harness include transmitting power, transmitting signals, protecting wires and connecting sensors. The engine wiring harness provides power to the engine by transmitting power, and controls the operating state of the engine by transmitting signals, such as ignition, oil injection, etc. The engine harness also protects the wires and connects the sensors, ensuring they work in harsh conditions.

The structure of the engine wire harness is generally composed of multiple strands of insulated copper wire with good electrical conductivity, and it is wrapped with insulating bushings that are resistant to high temperature, flame retardant and pressure. This design can not only protect the wire from the external environment, but also effectively transmit power and signals. At the same time, the engine harness is also equipped with various types of connectors for easy connection with the engine and the vehicle electrical system.

Engine wiring harnesses are subject to various influences during vehicle use, such as high temperature, humidity, vibration, etc. Therefore, the quality and stability of the engine harness is crucial to the performance and safety of the vehicle. Once the engine wiring harness is faulty, it may cause the vehicle to fail to operate normally or even cause a safety accident.

In order to ensure the quality and safety of the engine harness, the manufacturer will carry out strict testing and inspection during the design and production process. During the installation process, it is also necessary to ensure that the wiring harness is connected correctly to avoid problems such as poor contact or short circuit. In addition, regular inspection and maintenance of engine wiring harnesses is also an important measure to ensure vehicle performance and safety.

In general, the engine wiring harness is an important electrical part of the vehicle, which not only connects the engine and the vehicle electrical system, but also undertakes the function of transmitting power, transmitting signals and protecting wires. Ensuring the quality and stability of the engine harness is crucial to the performance and safety of the vehicle, so its effective design, production, installation and maintenance is very important.
