Engine computer wiring harness introduce

The most headache inducing issue in repairing high-end cars is the computer. When repair personnel encounter a computer malfunction, they dare not conclude that it is a problem with the computer. 1. The main function of the engine ECU is to adjust the engine's operation through the execution structure. In terms of use, it is a specialized microcomputer controller for cars, which controls many components on the car ECU stands for Electronic Control Unit ECU can be said to be the brain of the engine. Without it, the engine cannot operate normally. ECU's main function is to adjust the engine's operation through the execution structure. 2. There are many sensors near the engine of a car, and their function is to transmit data back to ECU. After processing by ECU, corresponding mechanisms can be executed to adjust the engine's normal operation. ECU is generally located in the engine compartment, so it can be said that there is no ECU, The engine cannot be used. If there is damage to the sensors near the engine, it can also affect the operation of the engine. 3. The sensors around the engine include the air influenza sensor, intake temperature sensor, etc. It can be said that basically all the sensors of the vehicle are gathered here. If the sensors are damaged, the ECU cannot collect important information about the car, and cannot accurately adjust the engine operation)

Internal maintenance of engine wiring harness

The engine wiring harness is generally composed of multiple strands of copper flexible wires inside and wrapped in plastic on the outside. The engine is like a person's heart, and the wiring harness can be called a person's veins. If the veins are not smooth, it can damage health and even cause diseases. Similarly, poor wiring will affect the engine's performance. Regular wiring harness maintenance: Wiring harness maintenance usually uses wiring harness protective agents, which work by forming a protective film on the surface of the engine wire/battery joint, Isolate moisture and avoid oxidation. Due to the high pressure resistance and insulation characteristics of the spray, it can also delay the aging and cracking of rubber and plastic fittings in the cabin, prevent electrical leakage caused by aging of the wiring harness. In addition, the protective film sprayed is not easy to get dirty and easy to wipe, which can keep the cabin clean for a long time

BMW 328Li introduce

The BMW 328Li has no significant configuration differences in the front part of the car. The hood extends in a wedge-shaped shape from the upper edge of the headlights to the lower edge of the front windshield, and the multi edged design makes the new hood look more dynamic. The enlarged front grille is a prominent feature of this generation of 3 Series, and the new headlight group closely connected to the grille is more aggressive. The chrome plated decorative strip in the fog light area, which is unique to the new 3 Series, is firmly covered by black tape, But the overall lines are clearly exposed. The side of the BMW 328Li can be clearly seen to be different from the overseas version of the 3 Series. The size of the rear door has a more obvious increase, and the line at the back of the side skirt tends to be more straight. This also means that it will be an authentic domestic new 3 Series sedan, which will provide more abundant rear seating space for Chinese consumers. The BMW 328Li will be equipped with a brand new 4-cylinder turbocharged engine, The maximum power is 240 horsepower, matched with a brand new 8-speed automatic transmission. The first six gears of the new transmission adopt a 1:1 gear ratio, and the last two gears are super ratio gears, which can help reduce fuel consumption during high-speed cruising
