【The owner's family car knowledge】When driving on the road, when you encounter these unclear problems, what will you do? Are you worried about your car? Whether you are fidgeting, want to find the source of the problem immediately, and diagnose your car in time, now let us understand the solutions to problems such as car lights turn off, acceleration and weakness!
What is going on when the car turns off while waiting for the traffic light?
Problem description 1: I recently discovered that the automatic model I was driving would automatically turn off when waiting for a traffic light. What's the matter?
reply: First check whether the throttle valve needs to be cleaned, then check whether the idle speed motor is stuck, and third, check the gasoline pump. There are two situations for the sudden flameout of the car, either the fuel is cut off or the fire is cut off. Therefore, it is recommended to drive the car to a 4S shop or a specialist repair shop for inspection to completely solve the problem.

Can a car use mineral oil?
Problem description 2: Recently, a friend suggested that I use mineral oil. Can this oil be replaced in the car?
reply: Mineral engine oil and synthetic engine oil refer to the source of the base oil in the engine oil. Mineral oil is extracted directly from petroleum by fractional distillation and is a mixture of multiple components; synthetic oil is artificially synthesized using chemical raw materials, is pure and contains no impurities. The disadvantage of mineral oil is that it contains impurities that cannot be separated cleanly, and it will deposit when used for a long time in the engine environment, which will be attached to the engine. Engines that use mineral oil for a long time will have a thick brown-black film, so it is not recommended.
What's wrong with the car's inability to accelerate?
Problem description 3: When driving recently, I often press the accelerator pedal to the end, and the speed has reached more than 4,000 rpm. The car will only increase the speed. This problem did not occur before. What is going on?
reply: According to your description, there are several possibilities:
One is that it may be caused by carbon deposits in the throttle, idle speed motor, intake duct, combustion chamber, and spark plugs; second, it is possible that long-term driving on congested roads in urban areas will also cause acceleration and weakness; third, there is The quality of the oil that may be used is poor, which will affect the gasoline filter element and the oil circuit, and may cause poor fuel supply, resulting in weak acceleration; it will also affect the service life of the three-way catalytic converter in the exhaust system. If the three-way catalytic converter is When there is a blockage, it will directly affect the acceleration of the vehicle, and it will also lead to an increase in fuel consumption. Fourth, it may be caused by a failure of the sensor, resulting in a phenomenon of weak acceleration.
What should I do if the brake disc is abnormally worn?
Problem description 4: When using a car recently, I found that the rear brake disc of the car has deep dents and abnormal noises. How do I deal with this situation?
reply: For the wear of the rear brake disc, it may be related to the material of the brake pads. The brake pads can be removed to polish the hard spots. For the abnormal noise of the brake, you can find a safer section, and then apply emergency braking during driving, so that the hard spots on the brake pads can be polished, and the abnormal noise will be eliminated after repeated several times.
Or remove the brake pads and chamfer the brake pads, which will also effectively reduce the abnormal noise generated during braking. This abnormal noise will not affect the normal use of the braking system, and it is not necessary to do any treatment.
