It s cooled, why can t the car throttle be stepped on

This may be the reason for the throttle hairpin, whether it is issued at the first foot of the throttle in the morning, just wash it.

If the accelerator does not move, the throttle is generally dirty, so it is good to clean the throttle and idle motor.

Experience in maintaining a car:

1. Clean the car in time.

Usually when running or parking on the road, the car is easy to be stained with dust particles, bird droppings, etc., especially after the rain, the acidic substances in it will corrode the paint surface of the car for a long time, causing the car to no longer be bright, and it will fade in serious cases.

2. Check and replace the car oil in time.

The normal operation of automobile engines and other components is inseparable from the lubrication and cleaning of engine oil. Therefore, it is necessary to check the oil scale in time to see if the oil is normal. Generally speaking, the oil should be changed every 5,000 kilometers of a new car, and the filter should be replaced if the oil filter is dirty.

3. Regularly check whether antifreeze, brake fluid, glass water, etc. are sufficient.

Antifreeze can ensure the normal driving of the vehicle in winter and is not easy to freeze. Brake fluid is an essential part of the braking system. Glass water is used to clean glass. These must be sufficient to keep the vehicle running.

4. Pay attention to the purification of the air in the car.

Everyone knows that new cars need to purify the air, run odors, and reduce toxic gases such as formaldehyde. In addition to opening windows for ventilation, it is also necessary to use air purifiers, such as Maya Blue Air Purifier, which is good, has no secondary pollution, and is highly sustainable. In the ordinary maintenance of the vehicle, it can also be deodorized, such as removing smoke odor, exhaust odor and so on.

Perform regular wheel alignment.

There are many axioms for cars to run, and sometimes there will be deviations, which is easy to bury hidden dangers. At this time, it is necessary to carry out four-wheel alignment of the vehicle in time, which has solved the problem of car deviation. There is no deviation in time, and regular four-wheel alignment is also very beneficial.

5. Check the tire pressure frequently.

Normal tire pressure is the premise to ensure that the vehicle is stable on the road, and too high tire pressure increases the risk of puncture and will also reduce comfort; Tire pressure that is too low will increase fuel consumption and increase tire wear. Therefore, it is best to check the tire pressure frequently, and it is best to bring your own tire manometer. If the forum pattern is smoothed, be sure to replace the tires in time.

6. Check the line regularly.

The normal operation of the car is inseparable from the strong support of the line, including various lights, car starts, etc., all use the line. It is necessary to regularly inspect and see which lines are aging or poor contact, and repair them in time to eliminate potential safety hazards.

There is water inside the throttle cable, which is frozen and cannot be stepped on. It's good to turn on the heater for a while in a hot car.

There are many reasons why you can't step on it, it is recommended to clean the throttle valve It may be that the sludge is causing it to get stuck.

Hello friends, check whether the oil circuit is abnormal and whether the oil pump is abnormal; Reference.

If there is a problem with the carburetor, the pump will not be able to oil.

Cause and solution analysis:

1. The hydraulic oil level of the automatic transmission is too low. Workaround: Add transmission fluid.

2. The hydraulic oil level of the automatic transmission is too high, and a large number of bubbles are generated after being violently stirred by the planetary row during operation. The solution: reduce the transmission fluid.

3. The clutch or brake friction pads and brake bands of the automatic transmission are excessively worn or scorched. Solution: Add lubricant to the automatic transmission or replace the damaged parts.

4. The oil pump of the automatic transmission is worn too much or the main oil circuit is leaking, resulting in too low oil pressure in the oil circuit. Solution: Comprehensively check the oil circuit of the transmission and repair it in time.

5. The clutch or brake piston seal of the automatic transmission is damaged, resulting in oil leakage. Solution: Replace the clutch or brake piston seals of the transmission.

6. The piston sealing ring of the shock absorber is damaged, resulting in oil leakage. Solution: Replace the piston seal of the shock absorber.

The reason why the engine throttle is not on and the acceleration is weak.

First, the reason for the oil circuit 1Lean oil mixture is too dilute, resulting in insufficient thrust of the piston caused by the gas action after the ignition eruption, and the combustion time is prolonged, resulting in engine overheating and other failures. When judging the cause of poor oil, the acceleration is poor in operation, when the oil pump is toggled by hand, the acceleration is improved, and the acceleration weakness occurs when the concentrated mixture is not used, and then we can say that the car is in a poor oil state.

There are many reasons for poor oil, which can be summarized as follows: (1) the adjustment of the main oil needle is too low; The oil level adjustment is too low; The main measuring hole is partially blocked; The interface is loose and leaking; The air filter is not installed; The fuel switch of the fuel tank is not well supplied with oil. (2) Poor engine sealing; The crankshaft oil seal on one side of the engine fails and leaks; Air leakage on the seam joint surface of the crankcase; The joint surface of the crankcase and cylinder is leaking or the piston assembly direction is incorrect.

3) Engine reed valve reason: reed valve damage; The rotary valve is reversed, causing a backspray. 2. The oil-rich mixture is too thick, causing the car to accelerate weakly at low speed.

Due to the excessive concentration of the mixture, the ignition erupts due to the lack of sufficient oxygen, so that the mixture combustion is incomplete, the power decreases and the economy becomes poor, and it is easy to produce a large amount of carbon deposits and block the exhaust device, which aggravates the phenomenon of acceleration powerlessness. In the analysis and judgment, it was found that the spark plug was easy to soak in oil, the carbon black was deposited on the surface, and the smoke exhaust of the muffler was abnormal during operation, and the gun was discharged. Moreover, the fuel is overconsumed, but the slight oil enrichment has little impact on the high-speed movement, and the fault phenomenon will be aggravated during operation.

There are many reasons for oil enrichment, which should be checked mainly from the following aspects: (1) the air filter is blocked; The plane is too high; oil spills; The main quantity hole is loose; The enrichment system is not well reset; The main air volume hole is blocked. (2) The fuel quality is not good, and the gasoline label is incorrect, which may cause deflagration; Gasoline storage is overdue, resulting in decomposition and decreased calorific value; There is moisture in the oil that makes the engine work discontinuous and there is a phenomenon of firing guns, and there are other components in gasoline.

2. Circuit reasons 1 Poor high-voltage spark and high-voltage power failure: due to the fault of high and low voltage components and lines in the ignition system, it may cause discontinuity of flashover, causing the engine to work intermittently and make acceleration weak; Weak high-voltage spark: The high-voltage current is too weak due to the fault of the electrical components and lines of the ignition circuit, which makes the engine work poorly.

The main causes of high-pressure spark defects are as follows; The spark plug is not working well or the gap is wrong; leakage of high-voltage lines and high-voltage caps; Leakage of high-voltage coil and internal moisture; ignition failure; The charging coil and the trigger coil do not know that the platinum gap is not correct and the work is not good; Capacitor damage and poor tie-up; Poor contact of low-voltage ignition line; magneto rotor sweeping and boring; There is a large amount of magnetic particle adsorption on the surface of the trigger coil. 2. Ignition time too early, too early ignition time will produce high-pressure sparks, which will bring great resistance to the piston that is rising and compressing, which will not only affect the acceleration performance, but also lead to the engine is not easy to start, poor idle speed and acceleration knocking phenomenon. The main reasons for premature ignition are as follows:

The white gold gap is too large; improper adjustment of the switchboard; Magneto rotor rolling. 3 Late ignition timeLate ignition time is because the ignition time misses the best burst time and prolongs the time for the flame to stay in the cylinder. Hope to adopt.

Generally, the throttle cannot be stepped on, mainly due to excessive carbon deposition in the engine, throttle and other places. When the car is cold, due to the astringent carbon deposit, the throttle line cannot be pulled up smoothly after the accelerator is pressed, so it will feel very hard, and if you use a little force, it will be overdone.

If there is a problem of carbon accumulation in the engine, throttle and other places, it is necessary to go to the 4S store for relevant cleaning.

Other reasons: In winter, the throttle may not be pressed because the throttle is frozen, resulting in the throttle cannot be opened and closed when the throttle is pressed, and the vehicle will naturally be unable to move. Secondly, it may also be because the throttle line is broken or frozen, which is generally not easy to occur, if you find that the throttle can be pressed, but the engine speed does not climb, it is likely to be this reason.

If the throttle or throttle line is found to be frozen after inspection, you only need to ignition the vehicle and idle it for 10 minutes, so that the engine can generate the heat of the handshake and melt the ice on the throttle, and no maintenance is required. If the throttle cable is broken, you can only call a tow truck for rescue.

If the cold car throttle can't be added, the hot car will be fine, it may be caused by the throttle valve is too dirty or malfunctioning, and you should go to the repair shop for maintenance as soon as possible.

What is the reason why you don't speed up when you step on the accelerator

1. The throttle is too dirty: when the vehicle is driven for a period of time, there will be more or less hidden carbon or sludge in the throttle opening and closing, which is due to the oil vapor in the engine adhering to the throttle sock valve, and after a long time, it will be mixed with the dust and moisture in the air to form dirty sludge or carbon deposits, which will make the accelerator unable to open when the car is cold, resulting in the speed can not be raised at low speed.

2. Throttle electronic fault: throttle generally does not have mechanical failure, the most common is electronic fault, because modern cars use electronic throttle, when the voltage imbalance that controls the throttle opening, there will be a situation where the throttle is not accelerated, if the cause of the throttle is too dirty, then it is likely that the throttle electronic fault caused by the throttle does not speed up.

Pacific Automobile Network] You can't step on the gas pedal when driving in winter because there is no hot car. After a cold night, the oil has flowed into the oil pan, but the oil cannot be transported through the oil pump immediately after the hot car to the piston where the engine needs to be lubricated the most, so it is necessary to warm up the engine. The hot train should not take more than 1 minute, and the best time is between 30 seconds and 1 minute.

Slow down the accelerator when driving on the road, and drive normally when the water temperature rises.

Precautions for driving in winter:

1. Maintain the battery in time in winter.

Lack of battery power is the most common problem in this season, so it is especially important to check the battery level. If you find that there are white oxides at the terminal of the electrodes, you need to flush them off with warm boiled water, because these oxides will cause the generator to run low, so that the battery is in a state of power loss, and in serious cases, it will also lead to the failure to drive and the battery is scrapped.

2. Replace the glass water in winter in time.

In winter, the weather gradually turns colder, and the minimum temperature in some parts of the north has reached below zero degrees Celsius, so you need to replace the antifreeze glass water in time. The antifreeze glass water should also be selected to be lower than the minimum temperature in the area, otherwise the glass kettle and pipeline will be frozen and cracked.

In winter, the accelerator does not move because there is no hot car. After a cold night, the oil has flowed into the oil pan, and the oil needs to be transported through the oil pump to the piston where the engine needs to be lubricated the most, so it is necessary to warm up the engine.

After a night of static use of the engine, the lubricating oil on each friction surface has basically disappeared, and the oil film protection has been lost; The low temperature increases the viscosity of the lubricant, resulting in poor adhesion and flowability, which increases the resistance of the engine when it starts. Driving at this time will increase the load on the engine and increase unnecessary wear. Studies by authoritative institutions have shown that the amount of wear and tear of the engine during cold start accounts for about half of the total wear.

Normal idle warm-up can reduce this wear and tear, which can extend the life of the engine. At low temperatures, the metal will show less elasticity and wear resistance, and only at normal operating temperatures can the engine achieve normal mating clearance and maintain optimal working condition.

It should be emphasized that the longer the hot car, the better, and many friends have entered the misunderstanding of hot cars. In fact, as long as the engine can reach a stable and normal idle speed, it can be driven. Before the carburetor engine reaches the working temperature, the oil supply system often cannot work normally, and the choke must be opened to idle and warm up, otherwise the speed will be unstable or even stall.

Push back the choke and the engine idles smoothly and you can start driving. Some EFI vehicles using advanced engine technology, precision computerized fuel injector injection is accurate, the degree of fuel atomization is high, it only takes a short time after starting, and the speed of the machine can be stabilized and reach the specified idle value, so the hot car time should not be too long.
