Car If you use it for a while, you may encounter problems countless jerks while running. This situation not only creates an extremely uncomfortable experience but also poses a lot of potential risks to the occupants of the vehicle. If there is no early remedy, the car will quickly deteriorate, reduce its lifespan and spend a lot of money on repair and maintenance later.
So how is it that we so often forget to teach respect by respecting the children themselves? Countless cars jerked while running why? How effective is the treatment? Together Thanh Phong Auto Find out in the following article.
Countless cars are jerked while running is a situation where when the driver puts the car into a state of multitude, the car jerks suddenly and does not move as smoothly as usual. This phenomenon can occur when the vehicle is traveling at high or low speed, which can cause a feeling of insecurity for the occupants of the vehicle.
Not only that, countless cars that are jerked while running also have many potential risks such as:
Reason: Fuel filter system, car oil filter It is used to clean the fuel before it enters the combustion chamber. After a period of use, these parts are often clogged with impurities. If not cleaned periodically, the fuel will not supply enough to the injection system. This will cause stalling in the middle of the road or jerking when it's in gear.
Treatment: Check and clean the fuel filter system, if these parts have problems, they can be replaced.
Reason: Air filter It is responsible for protecting the engine from agents such as dirt, pollutants, foreign objects entering the engine. If this part is dirty, the air entering the combustion chamber will not be enough, reducing the combustion efficiency of the engine, leading to the car shaking when it is loaded.
Treatment: Clean or replace the car air filter.
Reason: Problems in the ignition system such as spark plugs, power dividers, spark plugs, high voltage wires, etc. will all affect the spark plug's ability to ignite. At this time, the engine will not be able to start, start poorly or vibrate when starting.
Treatment: It is possible to remove the spark plugs and clean the contacts in the ignition system. If the spark plug is damaged or worn, it should be replaced.
ReasonThe fuel injector is responsible for providing fuel to the car engine. If used for a long time, this part can become dirty, causing many phenomena such as difficulty starting the vehicle, engine jerking when stepping on the gas / accelerating / stopping the car, fuel consumption, slow response, etc.
Treatment: Check and maintain fuel injectors regularly, especially when the vehicle is running more than 15.000km.
Reason: The oxygen sensor has an important role in measuring residual oxygen in the engine exhaust and transmitting data to the ECU control system. From there, the ECU will adjust the air-to-air ratio to ensure the most optimal combustion efficiency in the engine.
If oxygen sensor If it is dirty, it will cause erroneous information, affect the amount of fuel put into the combustion chamber, leading to conditions such as fuel consumption, overloaded injectors, jerky movement of the vehicle, vibrations when countless .
Treatment: Check, clean or replace the oxygen sensor; If the vehicle is about 10.000km, it should be replaced.
Reason: The MAF sensor is used to monitor the amount of gas moving from the outside of the intake manifold into the combustion chamber and transmit data to the ECU control system. If this part is dirty or faulty, it can cause information interference, affect the control of the amount of gas entering the combustion chamber, make the air-fuel ratio incorrect, increase or decrease the efficiency of the combustion chamber. This leads to the car stalling, convulsing, difficult to accelerate or rush back before pressing the gas.
Treatment: Use a resistance meter to check the MAF sensor signals, compare with the manufacturer's parameters. If there is a deviation, it can be cleaned, replaced or taken to the nearest garage for assistance.
Reason: The transmission control module is used to change gears when the driver accelerates. If this part is faulty, the gearshifting process will be less flexible, delayed, leading to jerky when pedaling.
Treatment: Should take the car to service, repair or replace the control module gear.
Reason: The power distributor cap is the bridge connecting the high-voltage wires to the cylinder, if this part gets wet (because the car is parked in a humid environment for too long), it will affect the power distribution, thereby making the car easily damaged. jerky when moving.
Treatment: Clean the distributor, replace damaged parts, and avoid excessively wet parking areas.
Reason: The throttle wire is responsible for mechanically linking the throttle and pedals. If used for too long, this part may wear out, affecting the effectiveness of the accelerator. As a result, the vehicle may jerk, difficult to accelerate, and wobble at loads.
Treatment: It is necessary to replace the gas line when detecting wear, cracking or breaking.
Reason: The task of the catalytic converter is to control emissions, converting toxic gases in the exhaust fumes into less toxic ones (by redox reactions). If this part is blocked, it affects the exhaust process, easily causing conditions such as: the exhaust has an unpleasant smell, the car consumes fuel, the Check Engine light comes on and the car jerks when moving. .
Treatment: Use a specialized cleaner to clean the catalytic converter, or take the car to a reputable garage for a new one.
In short, there are many reasons for this phenomenon countless cars jerked while driving. This may be a sign that car parts are having problems, you need to observe, preliminary check and periodically maintain them to promptly detect errors and fix them early, to avoid incurring a lot of costs in the future. after.
