Analysis of vehicle failure and acceleration failure when waiting for traffic lights
  • Automotive

Recently, I discovered that my self driving vehicle will automatically stall when waiting for the traffic lights. How is this going to happen? Check for yourself whether the throttle should be cleaned, check whether the idle motor is stuck or not. Three, check the gasoline pump. There are two cases of sudden extinction of motor vehicles, either oil or fire. Therefore, it is recommended to drive to 4S shop or specialized shop for inspection, and solve the problem thoroughly. Recently, some friends suggested that I use mineral oil. Can this oil be changed to the car? Mineral oil and synthetic oil refer to the source of the base oil in the engine oil. Mineral oil is a direct fractionation from petroleum and a mixture of various components; synthetic oil is made from chemical raw materials and is pure and contains no impurities. The disadvantage of mineral oil is that it contains impurities that can not be separated and clean. It will deposit in the engine for a long time in the engine environment. Long term use of mineral oil engine will have a thick brown black film, so it is not recommended. In the near future, when driving, often the accelerator pedal to the end, the speed has also reached more than 4000 turns, the car will speed up, before it will not appear such a problem, excuse me, what is this? According to what you describe, there are several possibilities: one is that it may be caused by carbon deposition on the throttle, the idle motor, the inlet and the combustion chamber and the spark plug; two it is possible to travel on a congested section of the city for a long time to accelerate the weakness; three is the poor quality of the oil that can be used. The noise of the gasoline filter and the oil path may lead to poor fuel supply, which can lead to acceleration, and will also affect the service life of the three element catalyst in the exhaust system. If the three element catalyst is blocked, it will also directly affect the acceleration of the vehicle and also lead to the increase of fuel consumption. Four may be caused by sensor failure, resulting in the phenomenon of accelerating weakness. When the car was recently used, it was found that the rear brake discs of the car had deep dents and were accompanied by abnormal noises. How do I deal with this situation? For the rear brake disc wear, it may be related to the material of the brake pad, and the brake pad can be removed to polish the hard spot. For the different brakes, you can find a safer Road, then take an emergency brake in the driving, so that the hard spots on the brake pad can be worn and repeated several times the noise will be eliminated. Or remove the brake pads and chamfer the brake pads. This will also effectively reduce the abnormal noise generated during braking. This abnormal noise will not affect the normal use of the brake system, or it can not do any treatment.
