In the daily use of the car, most car owners can only drive and cannot repair it. The phenomenon that the car owner is not a professional maintenance person is affirmative, but as a car owner, we still have to learn to judge the common trouble signs from some subtle phenomena of the car. This is helpful for early detection of hidden troubles in vehicles and early maintenance. The author of this article will teach you from the four major aspects related to safety to judge the hidden troubles from the subtleties.
When it comes to judging the hidden troubles from the subtleties, the author believes that the first thing to think of is the accelerator, brake, clutch, and steering wheel. So how much do you know about them among these four? Can you find out that there are hidden dangers in the car from these four places?
First of all, let's get to know the throttle: As a power control device of the car, the throttle is called the throttle but it does not directly control the fuel intake of the car. The fuel intake of the car is controlled by the opening of the throttle. , The opening degree of the throttle valve directly affects the calculation of the fuel injection amount by the engine computer, thereby controlling a series of actions such as starting, accelerating, overtaking, and fuel cut of the car.
The above are some principles. If the reader is difficult to understand, you can ignore it. Just remember the problem phenomenon mentioned below and the malfunction it reflects.
First, custom-made transparent car lampshades-if you feel that the accelerator is very astringent when you step on the accelerator while driving, the general reason is that the throttle is dirty or the throttle cable lacks lubrication. At this time, you need to do some cleaning and Lubricated
Second, the transparent car lampshade is customized-when refueling, if you feel that the throttle does not respond quickly or feel that the engine is boring, you should go to the repair station to check the spark plug, fuel injector and throttle to see if you need to replace the spark plug Or clean the throttle and fuel injectors.
The next thing you should recognize is the brake: the brake is a key part of the car; its working condition is directly related to the safety of our vehicles and people, and we must not underestimate it. So, when we usually step on the brakes, how can we find out the problems as early as possible and eliminate hidden dangers?
First, the transparent car lampshade is customized-when the brake pedal is turned off, the brake pedal must have sufficient hardness and height, and the brake pedal should not have any slipping feeling when it is stepped on to keep it still. If your foot feels sliding with the brake pedal, you should go to the repair station to check in time to see if there is an oil leak in the brake system.
Second, the transparent car lampshade is customized-after starting the vehicle, you should not step on the brake pedal forcefully, otherwise the brake system should be repaired immediately.
Third, custom-made transparent car lampshades-start the vehicle and step on the brakes. If the first foot is very low, it will be normal after a few feet. After releasing the brake pedal for a few minutes, then stepping on the first foot again will appear. Return to normal; this means that there is air in the pipeline of your brake system, and you should go to the repair station to bleed the brake system in time.
Fourth, if you hear the scream of iron grinding when you step on the brakes, check in time to see if the brake pads are thin and need to be replaced; if it is not thin, there is another possibility that the hard spots on the brake pads have worn the brake discs. Produced; (If it is a slight scream, you don’t need to care about it; after a while, it will be fine; but if it is a particularly loud scream, you should deal with it or replace the brake pads in time, otherwise it will cause the brake disc to grind out grooves for a long time. Come).
Fifth, the brake fluid should be checked from time to time. If it is too dirty, it should be replaced in time. Two years or 50,000 kilometers is also a time limit for replacing the brake fluid, and it is best not to exceed it.
The next step is the clutch: clutch problems rarely occur. However, there are usually several issues to pay attention to: if it is a cable-type clutch, pay attention to whether there is a jam when stepping on the clutch pedal, if there is any phenomenon, check whether the cable is worn or napped, and replace it in time; if it is a hydraulic clutch , You should pay attention to whether the pedal feels that it cannot be cut when gear is in gear. If there is, check whether the clutch hydraulic system has oil leakage. Another is to pay attention to whether the clutch is getting higher and higher and slipping. At this time, you need to check whether the clutch disc should be replaced.
The last thing to say is the steering wheel: the steering wheel is an important control component on the car, it can remind us a lot of things.
First, custom-made transparent car lampshades-if the steering wheel only trembles when the vehicle speed is between 80 and 90 kilometers, this signal is generally a reminder that you should do the vehicle tire dynamic balance;
Second, the transparent car lampshade is customized-the steering is heavy when turning; this phenomenon is likely to be caused by the tightness of the tie rod ball end or steering bearing of the steering system or the lack of fuel jamming, and another possibility is the tire If the air pressure is insufficient, it should be overhauled in time;
Third, the transparent car lampshade is customized-the direction is difficult to control; when driving or stepping on the brakes, the direction will deviate to one side. At this time, it may be that a certain part of the chassis suspension system is loose or the front wheel angle is wrong ; Or there is a problem with the bearing or shaft head on one side;
Fourth, the transparent car lampshade is customized-the steering gear is not properly returned or the angle of turning the wheels on both sides is inconsistent; at this time, it is necessary to check whether the four-wheel alignment of the vehicle is correct;
Fifth, the transparent car lampshade is customized-when you turn the direction, you hear a hum from the steering gear, especially when refueling. At this time, it may be caused by the lack of oil inside the power steering gear or the wear of the power steering pump; Always check to see if the power steering system is leaking oil and deal with it in time to avoid greater losses.
In general, car owners should pay more attention to some abnormalities in details during the process of using the car, because these phenomena may be the precursors of some major failures. Only by discovering the problems in time and solving them as soon as possible can the safe driving be effectively guaranteed.
