What causes the lack of power in the van?

How long has it been running? Is it time to maintain or the road condition you are running is a little worse, in this case you should maintain it in advance!

Look, there are still clutch problems, I guess that's it! The clutch is worn out!

There are many reasons for this: poor oil circuit, too little gap between brake pads and brake discs, bad oil, dirty throttle, low tire pressure, etc.

Common causes of insufficient engine power in automobiles;

1. Oil, the circuit is faulty. The oil circuit is not smooth, the air intake is blocked, and the gas is mixed and the gas is too thin or too thick; The ignition time is too late or the contact gap is too small or too large; engine exhaust pipe leakage; Leakage or detachment of high-voltage distribution lines, leakage or channeling of distributor jacks; The distributor cam is worn unevenly or the spark plug has too much carbon deposit, and the crack leakage.

2. Insufficient cylinder pressure; The cylinder gasket is not sealed, ablative; Valve seat inserts are ablative, unsealed or detached; The valve springs are too soft and work poorly; piston rings bite or match; The piston cylinder clearance is too large;

3. The gas distribution phase is abnormal;

4. A few cylinders do not work;

5. The engine temperature is too high; Water pumps, thermostats do not work.

good, the belt is slippery, the cooling system is too limescale;

6. The chassis is faulty. The clutch slips, the brakes bite, and the tire pressure is low.

The master explained in detail several reasons for the lack of power in the truck, and learned to solve it by himself.

Clutch slip is mainly manifested in the acceleration of the car driving, the speed can not increase with the increase of engine speed, and the power of the engine can not be completely transmitted to the driving wheel, resulting in driving weakness, especially when going uphill.

The main reason for clutch slippage is the lack of friction of the clutch friction plates; If the clutch is not in place, grab the gear or take it out of gear; long-term semi-clutch state sports car, stepping on the clutch and sliding; When the gear or disgear is not in place, the car will slam the throttle when the gear or disgear is not fully in place, resulting in abnormal loss of the clutch.

Of course, the speed of the car fuel pedal can not go up, we also have to focus on the engine, the power is the combustion of fuel, and the engine is responsible for providing fuel, and converting chemical energy into mechanical energy, so when the car is unable to refuel and speed up slowly, the engine system should also be checked as a focus.

First of all, we can do some simple checks on our own, such as whether the wrong oil is added, which is also possible, because adding low-grade gasoline may cause weak acceleration, resulting in a decrease in engine power and an increase in fuel consumption.

Then there is the engine oil system, which is not only important because it can be fully lubricated, but also reduce resonance and improve the smooth operation of the engine. If the engine oil is insufficient for a long time, the light one will have insufficient power and the fuel consumption will increase; In the heavier case, the piston strikes the door, causing mechanical damage to the associated connectors. In addition, a faulty gasoline pump and a clogged fuel filter can also cause a drop in engine power.

Then there is the intake system of the engine, the engine needs air in addition to oil, if the air filter, throttle and other components are blocked or there are problems, resulting in insufficient air intake, it will also cause the car to accelerate weakly and slowly, and there is a sense of frustration.

Cause:

On the one hand, it may be that one of the engine cylinders has failed, or it may be the oil circuit system or air intake system of the vehicle itself, and it is more likely that the circuit system has failed.

Among all the spare parts of the vehicle, the oil circuit system is the most prone to problems in the car. Insufficient fuel entering the combustion chamber can be caused by a clogged injector, a leaking oil line, a reduced gasoline pump, or a blocked gasoline filter.

The main reason for the lack of powerlessness in the car is that the engine suddenly cannot eat the oil, and when the gasoline filter is blocked, the car may not be able to eat the oil when it tilts. If you can't inject fuel at high pressure, you won't be able to atomize the fuel effectively, so the combustion efficiency will be reduced and the horsepower will not reach the desired target.

Fault detection of insufficient engine power:

1. Fuel supply system.

The fuel supply system is one place where cars are prone to problems. Insufficient amount of fuel entering the combustion chamber will cause insufficient power, which may be caused by clogged fuel injectors, oil pipe leakage, clogged gasoline filters, and reduced power of the gasoline pump over time.

2. Air intake system.

The engine of the car needs to run, in addition to fuel, there must also be air, otherwise the engine will not be able to run smoothly. The possible causes of insufficient power in the car are dirty and clogged air filters or throttle systems; Inlet air temperature, inlet air pressure sensor is not working properly, air flow meter is malfunctioning, etc. If there is a problem with these parts, it is enough to repair or replace them in time.

3. Exhaust system.

If the fuel is there, the air intake is also there, if the exhaust is not smooth, it will also cause insufficient power, which is generally caused by the blockage of the three-way catalytic converter.

First, the main reason for the lack of power is the poor combustion quality. However, there are many factors that affect the quality of combustion. The main reasons are as follows:

1. The atomization quality caused by poor fuel injection is not high. It is mainly due to the blockage of the fuel injection nozzle and the entire fuel injection system due to the gum in the fuel;

2. Excessive carbon deposition forms different degrees of detonation, some slight detonation, no obvious sound can be heard, but the loss of power is relatively obvious;

3. The air-fuel ratio is too high. The air-fuel ratio refers to the ratio between fuel and air. An excessively high air-fuel ratio is when the fuel is mixed with air, with too much air and too little fuel, which naturally leads to a lack of power.

The air-fuel ratio is automatically adjusted by the computer system according to the combustion quality, and when the computer system monitoring data shows that the combustion quality is not good, the air intake will be increased to ensure the exhaust gas emission after combustion. Therefore, when the gum in the fuel injection system and the carbon deposits in the cylinder gradually accumulate, due to the gradual deterioration of the combustion quality, the computer system will gradually adjust the air-fuel ratio, and the power will gradually weaken. It's a gradual process.

In order to maintain the best air-fuel ratio, it is necessary to maintain the cleanliness of the engine's fuel injection system and combustion chamber so that the combustion quality reaches a high standard in order to maintain good power.

Fuel additives can be considered to be added to the fuel Mafu multi-way sheet can effectively remove the gum of the fuel injection system and the carbon deposits in the combustion chamber, and at the same time can improve the fuel quality, make the combustion fast and clean, and keep the air-fuel ratio in an optimal state, so that the engine performance can be fully exerted and the power is full. I hope my answer will help you.

If you want to brush the program, you need to upgrade the ECU power, adjust the air-fuel ratio, ignition, pressure, etc., so it is also related to the regional altitude, etc., you can take a look at the HDP program, and the effect is not bad.

1. If the lubricating oil is not appropriate, the lubricating oil is too much, the engine oil will participate in the combustion, the mixer is not completely burned, the carbon deposit at the spark plug part will increase the fuel consumption, and the power will decrease, and the lubricating oil will be too little, which will cause dry friction between the parts, so that the engine will overheat, and the power will decrease and the fuel consumption will also increase.

2. Spark plug carbon deposit: If the carbon deposit on the spark plug increases or ages, it will make the speed of car ignition difficult, resulting in high fuel consumption, it is recommended to clean the spark plug every 3 to 40,000 kilometers or replace it regularly.

3. Tire pressure: Don't think that fuel consumption has nothing to do with tire pressure, when the tire pressure is too low, the contact surface between the tire and the ground is too large, it is when the tire wear is more serious, not only the fuel consumption will increase, but also the risk of puncture when it is serious.

1. Engine spark plug failure.

The most likely failure to occur when engine power drops is a spark plug failure. When the spark plug lacks fire or there is no fire, the combustible mixture entering the engine cylinder cannot be completely combusted, or even cannot be burned, which will lead to the poor operation of individual cylinders or all cylinders of the engine, and then lead to the decline of automobile power.

Second, the engine has serious carbon deposition, resulting in a decrease in power.

Another cause of engine power decline is carbon deposition, which is divided into two parts, one is the cylinder and spark plug carbon deposition, and the other is the throttle and intake tract carbon deposition. There is a fundamental difference between the two. The spark plug carbon deposition is no longer emphasized, focusing on the cylinder carbon deposition, when the cylinder carbon deposition is serious, it will lead to the deterioration of the combustion effect of the combustible mixture in the cylinder, resulting in insufficient combustion, and may also lead to the combustion chamber volume becoming smaller, thereby affecting the power of the automobile engine.

3. The engine intake and exhaust are not smooth.

The above-mentioned drop in power caused by carbon deposits on the throttle is a failure of the intake and exhaust systems, but this section would like to emphasize the decrease in engine power caused by the blockage of the air cleaner and three-way catalytic converter. First of all, after the air cleaner is blocked, the air intake is not smooth, and the combustible mixture in the cylinder is too thick, resulting in the inability to burn normally and completely, which in turn reduces the power of the engine.

Fourth, the engine power is insufficient due to poor oil quality.

After talking a lot about the power drop caused by the engine's own parts, let's talk about why bad oil products can also cause engine power to drop. The oil is not good, the most direct impact is the combustion effect, insufficient combustion leads to insufficient engine power, and the poor quality of fuel will lead to an increase in the amount of harmful gases in the engine exhaust, and more"Toxic"The substance can cause the front oxygen sensor to operate at too high a pressure and too high a temperature, which will cause a serious decrease in the power of the engine.

Nowadays, with the development of society, buying a car can be said to have become a necessary condition for everyone to travel conveniently. However, in the process of using the car after buying a car, we will encounter all kinds of failure problems due to the wear and tear of the parts. Next, we will talk about the most common fault problems encountered in automobiles, the causes of insufficient power and how to deal with them.

Reasons for lack of power.

1. Too much oil is added.

The addition and replacement of lubricating oil and other oil products in the usual maintenance of automobiles can be said to be a common item, but if you do not pay attention to the addition process, it will affect the addition of too much lubricating oil, which will make the car engine in the process of turning. As a result, the combustion of the outside of the cylinder block causes the engine components such as connecting rods and crankshaft handles to be overloaded. Then the power of the car engine will be reduced, and the fuel consumption will be increased.

2. Spark plugs.

Because of the different engine models and performance, the spark plugs required by the car are also different, if the spark plug that does not match it is used, it is very easy to affect the ignition failure, and then cause the lack of power of the car engine.

In addition, if the spark plug is not tightened according to the instructions for use when it is installed, it may also affect the lack of power.

3. Gasoline filter or gasoline pump problem.

Gasoline pump and gasoline filter is the key responsible for the main fuel of the car gasoline filtration and pump oil effect, if the gasoline filter element is too dirty or the oil pump has a problem, it will affect the engine due to too much impurities of fuel and other conditions, and then can not bring enough power to the car.

How to solve the lack of power in the car?

1. Spark plug problem.

Immediately check the condition of the spark plug, if there is no tightening condition, tighten it immediately, if the spark plug is damaged, as long as the spark plug is replaced with a good match, the fault can be eliminated.

2. Carbon deposition problem.

There is a large amount of impurities in automobile fuel, and in the long-term use process, these impurities will adhere to the oil circuit or engine due to insufficient combustion, and then affect the work of the engine, resulting in insufficient power of the car. In such a situation, we need to immediately clean the engine and its oil circuit to remove the accumulated carbon deposits.

3. Other fault problems.

There are many reasons for the lack of power in the car, such as gasoline filters, ignition coils and many other components, once there is a failure problem, it may basically lead to insufficient power. Therefore, once the car has such a fault problem, we need to investigate it one by one, replace the damaged one, and clean it if it is blocked and dirty. If the car owner is not proficient in the inspection, cleaning and replacement of various parts of the car, he can go to a professional repair shop or 4S shop to repair the treatment, and do not operate in an unclear situation to avoid further damage to the car.

Ask what causes the low power of the motor vehicle.

Answer: In this case, the power of the motor vehicle is too low, it is necessary to check specifically, it may be that the cylinder pressure of the engine is insufficient, or there is a problem with the timing control system of the engine, or the pressure of the oil pump is insufficient, and there may be a problem with the air intake sensor or the problem of the crankshaft position sensor, and. It's also possible that there is a problem with the engine's control computer. Specifically, it is necessary to use the computer to detect, according to the fault detected by the computer**, or the data flow of the engine to deal with the specific judgment.

See. Ask the question, how to deal with it, how to solve it.

1. Fuel quality due to insufficient engine power.

For cars, the fuel added is also a must-go, for example, a BMW and Chery need oil must be very different, you a BMW should add high-grade oil, at this time you choose to add 92 oil, there will definitely be a lack of power, not only that, the cleanliness and combustion rate of low-grade oil are relatively low, it is easy to burn incompletely, but also leave a lot of carbon deposits, causing damage to the engine.

2. Oil circuit failure due to insufficient engine power.

Oil circuit failure is that the fuel is not delivered to the combustion chamber through the fuel pipe, so that the engine is not operating normally, if the amount of gasoline into the engine combustion chamber does not meet the standard, the combustion chamber does not have enough fuel to ignite and blast, which will lead to the power of the car is getting smaller and smaller, the main reason for the failure is the fuel injector is blocked, the gasoline pump power is reduced and the gasoline filter is blocked, the owner can go to the repair shop for inspection.

3. The air intake system of insufficient engine power.

The power output of the engine is formed between gasoline and air to form a mixture of gas to ignite the power, if there is a problem with the intake system, it must also bring small engine power output, some owners have also experienced the high air pressure in the western region, the vehicle will have obvious power deficiency, at this time it is actually the air is thin, the air intake is caused by a small amount of air, so the intake system generally fails because of the blockage of the air filter and valve system.

4. Engine cylinder with insufficient engine power.

As an ordinary model, it is generally a 4-cylinder engine, if there is a cylinder if there is no normal ignition, the power will be obviously insufficient, even if the tandem bicycle is the same, if there is one person who does not step on it, the other person will feel particularly heavy, the owner can start to see if the steering wheel or the body is shaking to observe the problem.
