What happens when the car is unable to climb a hill and is unable to refuel?

The engine oil system is where the car often has problems, and the fuel injector is blocked, the oil pipe is leaking, the gasoline pump power is reduced, and the gasoline filter is blocked. In addition, the same is true for the air intake system, the engine needs air in addition to oil, if the air filter, throttle and other components are clogged or there is a problem, resulting in insufficient air intake, it will also cause the car to climb the hill weakly.

If the car is not climbing and the steering wheel or body shakes significantly when it stops, then it is a sign that at least one cylinder of the car's engine is not running properly or stalling. In general, a four-cylinder engine can still run if one of the cylinders does not start, and as the number of cylinders increases, this symptom becomes more difficult to detect.

In addition, we can judge that there is a problem based on other symptoms, such as black smoke from the exhaust pipe, then there is a problem with the combustion chamber, ignition system, and valve; If there is blue smoke coming out of the exhaust pipe, then it is possible that the engine oil has run to the combustion chamber, which is what we call burning the engine oil. Finally, there is the situation of insufficient tire pressure, which can also cause the car to feel sluggish in climbing.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

When going uphill, it was found that there was a significant lack of power, and the MT could be downshifted to improve traction uphill. , AT can release the throttle and press it down hard, allowing the transmission to force downshift uphill. It is worth mentioning here:

It should be accelerated before going uphill. But it's not easy to judge at night, unless you know there is a slope. When descending a steep slope, the MT should be lowered to the appropriate gear in time.

Utilize the engine reduction ratio or attach brakes.

When the car is driving uphill and feels that the throttle is weak and the gas cannot be refilled, there can be many reasons for its failure. Mainly focused on, engine oil circuit system, automobile air intake system, engine combustion problems, spark plug failure, insufficient tire pressure and so on.

The failure of the engine oil circuit system will lead to the inability to provide enough fuel to the engine when going uphill, the combustion effect in the cylinder is poor, and the power of the car is insufficient, resulting in a sense of powerlessness in the car. Possible faults are: oil pipe leakage, clogged gasoline filter, faulty gasoline pump, dirty fuel injectors, etc.

The main reasons for the failure of the car's air intake system are that there is too little air in the engine and insufficient fuel combustion. The general fault locations are: the air filter is too dirty, the throttle is too dirty, and the air intake is insufficient.

Replacing the air filter and cleaning the throttle will do the trick.

Insufficient combustion is mentioned, and in addition to the above factors, there is also the possibility of spark plug failure. Because the ignition effect of the spark plug is poor, the combustion is not sufficient, and the car accelerates slowly.

We can also check the exhaust status to find the fault. If there is blue smoke coming out of the exhaust pipe, it may be an oil leak, and it may be a fault of the engine burning oil. If there is black smoke coming out of the exhaust pipe, it could be an ignition system failure, a combustion chamber failure, a throttle problem, and so on.

If the engine shakes during acceleration, it may be that the engine is missing a cylinder, or that one of the cylinders is malfunctioning or even stalling. For example, if a car has a six-cylinder engine, one cylinder does not rotate, and the other cylinders work, the car can still run, but the power is very different. The problem of lack of cylinder generally needs to be carefully checked by a 4S shop or repair shop before it can be confirmed.

There are four reasons why:

The gear is too high, you should change to a low gear when climbing:

Manual transmission models, when the gear is too high, the speed is difficult to go up, when climbing should be hung to 1-3 gears depending on the situation, automatic transmission models, if the slope is steep, it is recommended to hang L gear or 1st gear, 2nd gear to climb.

2.The idle number is too low, and the idle speed is unstable:

There are many reasons for this situation, including the idle motor line, and it may also be due to problems elsewhere in the engine, resulting in unstable idling, including sensor failure, engine combustion failure, intake air leakage, etc.

3.Automatic transmission slippage:

The reasons for this failure include hydraulic oil, the oil level is too low, the clutch or brake pads, brake band is overwhelmed or burned, the oil pump is overworn or the main oil circuit is leaking, the one-way overtaking clutch slips, and the clutch or brake piston seal ring is damaged resulting in oil leakage.

4.The question of the dynamics of the car itself:

Because the slope is too steep, the car's powertrain cannot support the normal ascent.

After using the car for a while, some owners find it boring to climb mountains. Even if they step on the accelerator, they can't increase the speed. What the hell is going on? What is the reason why the car can't be refueled uphill? What's going on with boring car climbing?

1.The oil system is where the car often goes wrong. Clogged injectors, leaking oil pipes, reduced power of the gasoline pump, clogged gasoline filters, can all cause the car to go uphill.

The main reason why the car feels weak is that the engine does not have enough oil when going uphill, the combustion efficiency decreases, and the horsepower does not meet our requirements.

2.Also, the same goes for the air intake system. In addition to oil, the engine also needs empty air. If the air filter, throttle and other components are clogged or there is a problem, resulting in insufficient air intake, it will also cause the car to be stuffy when climbing.

3.Spark plugs are also a common failure**. If the spark plug ignition is poor, it may cause problems with weak acceleration.

4.If the car is bored when climbing a hill and the steering wheel or body shakes significantly when stopped, then it means that at least one cylinder of the car's engine is running abnormally or stalling. Generally speaking, if one cylinder of a four-cylinder engine does not start, the engine can still run, and as the number of cylinders increases, this symptom becomes more difficult to detect.

5.In addition, we can also judge that there is a problem according to other symptoms, such as black smoke from the exhaust pipe, then there is a problem with the combustion chamber, ignition system, and valve; If there is blue smoke coming out of the exhaust pipe, then it is possible that the engine oil has run into the combustion chamber, which is what we call burning the engine oil.

6.Finally, there is the case of insufficient tire pressure. This situation can also lead to a boring feeling of climbing.

Summary. When the vehicle has too much carbon deposit, the gasoline can not be completely burned, and the efficiency of the engine cannot be fully exerted, giving people the feeling that the car cannot be filled with oil. In this case, the carbon deposits should be cleaned up.

The quality of the oil is not enough. If the quality of the car oil is too low, impurities will appear in it, clogging the gasoline filter and other places, so that the transportation of gasoline cannot circulate, affecting the operation of the engine. Therefore, it is necessary to replace high-quality fuel.

The intake and exhaust systems are clogged. When the intake or exhaust system is clogged, the gas in the empty engine does not circulate, reducing the combustion efficiency of gasoline and turning vehicle power into meat. In this case, go to the 4S shop to check the intake and exhaust system.

When the vehicle has too much carbon deposit, the naixun gasoline can not be completely burned, and the efficiency of the engine can not be fully exerted, giving people the feeling that the car cannot be filled with oil. In this case, the accumulation of carbon should be cleaned up. The quality of the oil is not enough.

If the quality of the car oil is too low, impurities will appear in it, blocking the gasoline filter and other places, so that the transportation of gasoline cannot circulate, affecting the operation of the engine. Therefore, it is necessary to replace high-quality fuel. The intake and exhaust systems are clogged.

When the intake or exhaust system is clogged, the gas in the empty engine does not circulate, reducing the combustion efficiency of gasoline and turning vehicle power into meat. In this case, go to the 4S shop to check the intake and exhaust system.

The slope that can be up in the first three gears can now be up in one gear, and it hasn't been opened for a year.

In this case, there are generally two possibilities The first is caused by the ignition and ignition performance of the spark plug, and the second is that the gasoline filter is not well filtered The load of the bridge engine itself is not as large as when going uphill when it is changed to a flat road, so it is not obvious to understand!

There are many reasons for insufficient power: it may be that the oil quality is poor, the carbon deposit problem is serious, the gasoline filter is dirty, the gasoline pump is damaged, and the three-way catalytic is blocked.

Poor oil quality.

When there are too many impurities or too much water in the fuel, it will naturally lead to insufficient power, and inferior fuel can easily lead to the blockage of small holes or filtering parts such as oil pump filter, gasoline filter, and finch head fuel injector, resulting in poor oil supply and reduced engine function.

2.The problem of carbon deposits is serious.

Excessive carbon deposition in the throttle and intake duct leads to insufficient air intake, gasoline can not be fully combusted, and the power naturally cannot keep up, and fuel consumption will be increased to a certain extent. The fuel injector is blocked, resulting in poor fuel atomization, or simply not being injected with a number of worms. This leads to a lack of cylinders and a decrease in engine output.

3.The ignition coil is damaged.

The ignition coil is damaged, a cylinder cannot be ignited and cannot work normally, the lack of cylinder power is insufficient, and it is accompanied by engine shaking. If the ignition coil is damaged, it should be replaced in time.

4.The gasoline filter is too dirty.

If the gasoline filter is not changed for a long time, the gasoline filter will not be clean, and in serious cases, the gasoline filter will be blocked, and the common phenomenon is that the car is easy to turn off and often does not ignite.

5.The gasoline pump is damaged.

The oil pump is damaged, and the improper operation leads to insufficient fuel pumping, which will eventually make the engine inject insufficient fuel and reduce the engine power output, so that the car is not powered enough.

6.Three-way catalytic blockage.

A common phenomenon in three-way catalysis is that the engine fault light is on, and the accelerator pedal is pressed to the end, only the engine is heard, and the vehicle accelerates slowly.
