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

Audi TT introduce

The Audi TT is a sports car developed by Audi, which was first launched in 1998. As a sports sedan, the TT model has achieved great success in the market with its almost identical beautiful appearance and excellent performance to the concept car version. In the early stages of the first generation, some car owners complained about unstable high-speed turning and accidents. Audi adjusted the suspension system of the TT and added a rear spoiler version to the rear of the car, reducing the lift at the rear of the Audi TT from 148 pounds to 53 pounds at a speed of 125 miles per hour, The 64 pound rear lift of the BMW Z3 Coupe and the 68 pound Porsche Boxster, as well as the 104 pound Mercedes SLK, are lower than those of the same period at the same speed. The Audi TT is a pure sports car. There are three models sold in China, namely the TT Coupe 1.8t, TT 2.0TSI, and TT 3.2quattro convertible (soft top). Audi continues to launch a series of completely new cars, from A4.A6 to the current A8 and TT. [2] Audi TT's competitors include BMW X1, Mercedes SLK, etc
