What happens when the front end of the car is driven by an automatic transmission?

1. There are many reasons for the smell of burning, the smell of burnt organic oil, this is generally from the front, there may be two reasons: one is that the organic oil drips on the body or exhaust branch pipe when adding engine oil; Second, the engine valve cover is loose and leaking oil. The burnt smell of plastic glue:

This smell is particularly pungent, different from the smell of rubber tires, it may be a short circuit in the car circuit, and it is generally recommended to pull over if the bad smell is asked.

Check it out. 2. If it smells of gasoline, it is probably a carbon canister in the engine compartment or under the floor.

There is a fault, or check whether the lower fuel tank is normal, whether there is a leak, if it is a burning smell: it may be that there is an oil leak somewhere in the engine compartment, and the oil leakage is burned at high temperatures; It may also be that there is a short circuit somewhere on the vehicle line, and the smell of the burnt Jiao line.

3. Special attention is paid to the fact that once the wire overheating phenomenon is found, it must be stopped immediately to find out the cause, don't look at the smell of wire burning, but the danger index is very high, under normal circumstances, the wire temperature will be too high in spring and summer, if not found in time, it is easy to cause complete damage to the circuit, engine cylinder, and even spontaneous combustion of the whole vehicle.

The general smell is first, the tire friction odor, the second engine water lack and high temperature, the smell of burning, the third gearbox clutch friction plate friction burned odor, and the belt friction caused by the odor, one by one.

Hello, according to your description the car has an unpleasant smell after driving for a while, mainly due to. All kinds of oil encounter this smell of high temperature, I hope mine is helpful to you, hope, thank you.

Hello. Specifically, first, check whether there is oil leakage in the engine compartment. Second, the plastic parts are relatively close to the heat source of the engine. The smell of the third exhaust. Hope mine is helpful to you.

Air conditioning work consumes engine power, and the shivering turns out to be a resonance caused by a lack of power. Generally speaking, when the air conditioner is turned on in the idle state, the idle speed will automatically increase to compensate for the power consumed by the air conditioner. You can try cleaning the throttle to solve your problem.

This will cause this situation, and your use is still very related, according to the use of automatic transmission conventions, L gear is generally only in rain, snow weather conditions, road adhesion is low when the use of the use, it will improve the engine rotation, gear driving, due to the good condition of the road, the speed will rise quickly, and at this time the transmission will not be limited and will not carry out shift operation, and then make the engine speed not only rise, produce huge heat, and these heat baked to the interior decoration of the vehicle or three-way catalytic device, a vague taste will be produced. Therefore, in the case of good road conditions, you should avoid using L gear, on the one hand, it is conducive to increasing the speed of the vehicle, reducing fuel consumption, and on the other hand, the people can protect your car's engine and transmission from damage.

Automatic cars usually use a hydraulic transmission to replace the mechanical clutch of manual cars, so there is no clutch pedal. When the engine speed is low, the torque transmitted by the fluid is limited and not enough to propel the car forward. When the joystick is put into forward gear, release the brake pedal, and as the refueling and engine speed increase, the transmitted torque increases, pushing the car forward.

If the driver with a high level of manual transmission car is compared with the automatic transmission car, under the same driving conditions, the automatic transmission car generally consumes about 6 10% of fuel, and the automatic transmission car is higher than the same type of manual transmission car in terms of fuel consumption, about 1 liter higher per 100 kilometers. In terms of car cost, the cost of an automatic transmission is higher than that of a manual transmission of the same model. Its advantage over manual transmissions is that they are easy to drive.

There are two main forms of automatic transmissions used in automobiles. One is a stepless automatic transmission, the other is a continuously variable automatic transmission (CVT), the most commonly used in cars is a mechanical continuously variable transmission, which uses a V-shaped metal transmission belt or transmission chain to transmit torque in the V-shaped groove of the active and passive working wheels. This type of transmission is usually used in smaller vehicles.

The problem may be a little complicated if it smells paste, first see if the line is burned out, and if so, stop for repair.

Normally, due to the good road conditions, the speed of the vehicle will rise quickly, but at this time, the transmission will not shift due to the limitation, and then the engine speed will not only rise, but also generate huge heat, and the heat bakes the interior decoration parts of the vehicle or the three-way catalytic device, it will produce a vague taste.

If the usage habits are not good, it can be repaired or inspected.

It is recommended to check it in a professional place to avoid breakdowns during driving.

It may be caused by the heat emitted by the transmission, pay more attention to maintenance.

It is recommended to go to a professional repair shop for repairs.

It may be related to the oil product, or the road surface on which it is traveling.

It still has a lot to do with your use, and it may also be caused by the weather.

I could be a problem with the road surface, or a driving habit.

Pay more attention to the 4S shop to maintain the car.

Because automatic transmission cars sometimes change gears on their own.

The mushy smell is generally a problem of short circuits.

There is a mushy smell that may be caused by a short circuit in the circuit, and it is recommended to check and repair.

It could be that the circuit is burned. To be on the safe side, it's best to check it out.

It should be that the engine burned, or there was a problem with the throttle.

The throttle was pressed too hard and the clutch plate was damaged.

Because the components may be aged and cannot withstand long-term operation.

It may be that some parts of the car are abnormal, and a comprehensive investigation is carried out.

Shifting gears back and forth creates some mushy taste.

When the road is in good condition, you should avoid using the L gear, on the one hand, it is conducive to increasing the speed of the vehicle, reducing fuel consumption, and on the other hand, the public can protect your car's engine and transmission from damage.

1. Violent driving of a car:

When the driver is violently driving the car, the load on the engine increases, so the engine overheats up. Generally speaking, when we are driving a car, we must drive steadily and let the engine run smoothly, so that the engine can work better, and it can also extend the service life of the engine to a certain extent.

2. Lack of coolant:

When the coolant is missing, the engine will naturally not be able to cool down normally, and in this case, the coolant of the car should be replenished immediately. Generally speaking, there is an English representation on the car radiator, max refers to the maximum value, and min refers to the minimum value. If the coolant is lower than the minute mark, which is the minimum value, it means that the coolant of the car is insufficient.

3. Serious carbon deposition in the engine

When the engine carbon deposit is not cleaned up in time, the oil pipeline will be blocked, and the fuel can not be transported normally, so that the engine will overheat, and the engine carbon deposit should be cleaned up in time.

Hello, dear, car master exclusive technician for you service, attentive, careful, concentrate on answering your car questions, for you to find the corresponding problem solutions and solutions, will provide you with a satisfactory answer! We hope you find this service helpful. If it helps you, we look forward to your likes and attention.

Happy driving. Pro, hello, there is a burning smell in the car, the relevant reasons are as follows: first, if it is in the cab, this should check whether the relevant wiring is connected or connected to the phenomenon of electricity Second, if it is the heater to have this smell, this should be checked, is it not the warm air water tank is too dirty caused by this phenomenon need to clean up the dirty things on the surface of the warm air tank Third, if it is the engine compartment of the vehicle, this should check whether there is organic oil leakage, if the oil leaks, There will be this smell.

It means that you are buying an authentic FAW-Volkswagen Tange!! The double clutch burnt paste taste is famous!

It is impossible for the engine of a new car to smell of burnt plastic after it is started, and the specific analysis is as follows:

1. Clutch.

The taste of the friction plate, you can ignore him, just find a chance to take a look at it when you have to maintain it.

2. Check whether the main engine harness is scorched, especially on the exhaust side, and be sure to check it carefully as soon as possible to prevent short circuits.

3. Because of the exhaust gas generated by the engine, this is normal. If the smell is very pungent, it may be that the exhaust pipe is stained with the smell of burnt plastic, and you can go to the repair shop to check and deal with it.

4. The plastic parts have just been in contact with the heat source, and the surface has not been oxidized. Just open it for two days.

This is a normal phenomenon caused by the heating of the engine, and it is good to drive it for a while.

Mainly because of the poor plastic material, the heat of the engine accelerates the release of harmful substances in the plastic.

This is mainly the reason for the new car, the plastic will produce this smell after heating, and it will generally be fine after a while, and there is no big problem with this.

Elephant hair burns stinking.

Taste it. If it is a manual gear, it should be the clutch plate burning, generally a novice specialty, the clutch is not completely released, the half-clutch state throttle accelerates, and the clutch slips and friction will be like this.

This can allow professional people to try to get out of the car again, it is not necessary to change, the burn is not serious, as long as you pay attention when you drive it in the future, you should still be able to continue to use it. But after burning, you have to pay attention to it, and the life expectancy will be shorter after all. If the car is obviously not accelerating well, and the revs go up but the speed goes up slowly, then you have to change.

In the case of automatic transmission, check the engine compartment for foreign objects such as plastic that smell due to high temperatures.

Automobile exhaust is the product of engine combustion, after the three-way catalytic converter purification, the general exhaust gas mainly contains water vapor, nitrogen, carbon dioxide, and a small amount of nitrogen oxides. If the exhaust gas has a peculiar smell, such as smell, etc., the vehicle must be overhauled in time.

There is a condition where the exhaust gas contains the smell of raw gasoline during a cold start, which is normal. Because the vehicle is in an open-loop state during cold start, the ECU of the car provides air intake and fuel injection according to the temperature at that time and the preset program, the mixture concentration is not in the best state, resulting in insufficient combustion, a large amount of fuel is discharged without combustion, and the three-way catalytic converter has a low temperature and is not working, which cannot catalyze the fuel in the exhaust.

If the car still smells of raw gasoline when it is hot, it is not normal. Systems such as fuel lines, carbon canisters, etc., need to be inspected to see if there are any leaks. Some vehicles burn engine oil, and the exhaust gas also has a peculiar smell, which is caused by the combustion of engine oil, a burnt smell.

If the vehicle burns oil, it must be repaired immediately, which can cause premature wear and tear of the engine, reduce the service life, and damage the oxygen sensor and three-way catalytic converter. Exhaust emissions will also be abnormal, and the annual inspection will not pass the exhaust gas test.

It is more common for the vehicle to emit a foul smell when it is hot, which is neither the smell of raw gasoline nor the burnt smell of burning engine oil. It can occur at hot idling or high revs. In some cases, it is accompanied by the phenomenon of weak acceleration of the vehicle and a sharp increase in fuel consumption.

Once this situation occurs, we can conclude that the exhaust gas of the car is seriously exceeded, mainly CO exceededs, CO is a toxic gas, which can seriously cause death.

Why does the car CO exceed the standard? The main reason for CO exceeding the standard is that the mixture is too thick, if the fuel is too much, or the air intake is too small, resulting in incomplete combustion of carbon in the fuel to generate CO, the normal combustion should be CO2, CO2 is a colorless and odorless gas. Excessive CO in the exhaust gas can lead to the failure of the oxygen sensor, the high-temperature sintering of the three-way catalytic converter, and even the damage of the trip computer.

Therefore, once the vehicle has an exhaust smell, it is best to deal with it immediately to avoid greater losses.

The most basic exhaust odor treatment procedure is to use Tongjue three-way catalytic cleaning agent to clean the inlet duct, intake valve, combustion chamber, oxygen sensor and three-way catalytic converter.

If the odor persists after cleaning the carbon deposits, the vehicle should be overhauled, focusing on the oxygen sensor and wiring, ECU failure, air intake system such as air flow meter, air pressure sensor, etc.

Therefore, for the smell and smell of vehicle exhaust, riders must not take it lightly. Many people think that as long as the car can move, normal driving is fine, and there is no need for too much maintenance. This view is undoubtedly wrong, car maintenance lies in the daily small maintenance, in order to avoid major repairs, reduce vehicle maintenance costs, this is the real way to maintain the car, save money.

The possible causes are: the smell of wire harness coking; Foreign objects are sticking to the exhaust pipe; the smell of slippery clutch plates; Odor when brake shoes are locked.

Mainly check whether the clutch plates are slipping and whether the brake shoes are not homecoming.

If you smell mush, it is estimated that the clutch is slipping, take the time to check it, and the clutch plate can be replaced if it is worn badly.

It may be that there is a short circuit in the wires that burned the plastic, and it is recommended to check the circuit.

Belt slippage, line short-circuit, clutch slippage are all possible.

The pipes of the oil pump may be leaking. If that's okay, check the circuit.
