One of the most frightening things in driving a self-driving tour is that the car is out of order, and there are often warning signs before a malfunction occurs. Judging from the abnormal performance of the engine in a timely manner, it can not only quickly solve the problem but also minimize the damage. Fault precursors 1: Abnormal noise from the chassis Most of the noise in the chassis in the city comes from two parts: (1) Three-way catalytic converter (2) Suspension In the first, especially in cities where roads are congested, or in areas with poor oil quality, carbon deposits have accumulated in the three-way catalytic converters. After the excessive accumulation of carbon deposits, the blocks will fall off. The carbon deposits will not come out in this ternary shell. The son of Grande Lang sounded. If there is such a problem, the exhaust of the engine is usually guilty of black, which is caused by the incomplete combustion of a typical engine. It is better to replace the spark plug/injector before starting a self-driving tour, or to replace and recalibrate the ignition advance angle. The second problem is suspension, which is especially noticeable at high speeds. It can be unimaginable if the driver continues to drive. Failure precursors 2: Engine mourning (1) Engine shake (2) Suddenly high idle speed (3) Crisp percussion The car feels terribly jittery, shuts down, and tests the broken cylinder. It is very likely that the spark plug or injector has failed. Remind everyone to stay away from counterfeit spark plugs. After this kind of shaking failure, please do not continue to move forward. Parking in the area calls for the most reliable rescue. Suddenly high idling, the car is running normally on the road, and the engine is idle at 2700 when the parking is stopped in neutral. This kind of problem is mainly caused by the stuck/circuit failure of the idle motor. If the idle speed is too long, it will cause the engine to open. The car is driving with a sudden and regular "bang" noise, usually caused by excessive valve wear or excessive wear of the timing chain. The wood has a relationship. After this sound has appeared, it is not too much to continue driving for 1,000 kilometers. The problem, open to the auto repair factory for a pair of OK. Fault precursor 3: Strange smell Especially in the summer, when I was sitting in the car, I felt a plastic smell, and after five minutes of opening the window, the smell spread. When the weather is hot, it is very easy for the circuit to fail. The flammable location is usually around the relay box or around the battery. The fire extinguisher needs to be fired before getting off the train, because it is possible that the circuit has already had a fire. After the engine hood is opened, large amounts of oxygen enter the fire and the fire becomes larger. Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other. The angle steel can be composed of various stress-bearing components according to the different needs of the structure, and can also be used as a connection between the components. Widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, busbar support installation, and warehouses Shelves etc. Angle Steel Bar,Angle Steel,Angle Bar,Stainless Angle Bar Shandong Rizhaoxin Metal Products Co., Ltd. , https://www.sdrizhaoxinsteel.com
Drive to hear this sound must be immediately stopped careful car crash
