The oil light is on when the Chevrolet Jingcheng engine is idling after an overhaul

There are strict standards for engine overhaul, and the following is an important "indicator" for engine overhaul, and the engine is going to be overhauled on the surface of these signs.

1.Cylinder pressure difference: The cylinder compression pressure should meet the original design regulations, check that the tachometer and cylinder pressure gauge do not meet the requirements and are unqualified, and the pressure difference between each cylinder is unqualified

The difference between the pressure of each cylinder and the average pressure of each cylinder is not more than 8 measured with a tachometer, cylinder pressure gauge or with an engine comprehensive analyzer (the pressure difference between each cylinder of Yuedong engine that does not meet the standard is unqualified.) When the cylinder pressure of the Yuedong engine is lower than its standard value, there will be serious black smoke.

2.Large fluctuation of idle speed: the engine is stable at idle speed, and its speed meets the original design regulations. The speed fluctuation is not more than 50r min, and the operation test is carried out with the tachometer or measured with the engine comprehensive analyzer.

3.Low power: the maximum power of the engine shall not be lower than 90 of the original design calibration value, and the dynamometer shall be measured according to the relevant regulations.

4.Fuel consumption rate: The minimum fuel consumption rate of the engine shall not be higher than the fuel consumption meter required by the original design.

5.Low torque: the maximum torque of the engine shall not be lower than 90 of the original design calibration value.

Oil pump problem, improper adjustment of tile gap.

The car shows that the causes of engine failure are as follows: non-scheduled maintenance; oil deterioration; clogged air cleaner; Dirty air intake ducts; There is a lot of crankcase sludge; fuel system maintenance; The tank is rusty and scaled.

The causes of car engine failure are as follows:

1. Unscheduled maintenance: the failure of the vehicle due to poor engine maintenance accounts for about 50% of the total failure. "It can be seen that engine maintenance can play a crucial role in extending the service life of the vehicle.

2. Oil deterioration: After a certain mileage of the vehicle, the performance will change, which may bring various problems to the engine. In order to avoid the occurrence of these failures, the oil should be changed regularly in combination with the use conditions, and the oil volume should be moderate, generally between the upper and lower limits of the oil scale, and it needs to be replaced regularly.

3. Air filter blockage: According to different use cases, the air filter element should be cleaned regularly, and the method that can be used is to blow high-pressure air from the inside to the outside to blow out the dust in the filter element. Since the air filter is paper, it is important to pay attention to the air pressure not to be too high when blowing, so as not to damage the filter.

4. Dirty intake pipe: The air pipe is very important for the normal operation of the engine, if the intake pipe is too dirty, it will lead to the decline of charging efficiency, so that the engine can not run within the normal output power range, and aggravate the wear and aging of the engine.

5. Crankcase sludge: During the operation of the engine, the oxides of high-pressure unburned gas, acid, moisture, sulfur and nitrogen in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, so that it is mixed with the metal powder produced by the wear of parts to form sludge. A small amount of sludge can be suspended in the oil, and when the equivalent amount is large, it can be precipitated from the oil, clogging the filter and oil holes, causing difficulty in engine lubrication, thereby aggravating the wear of the engine.

6. Fuel system maintenance: The maintenance of the fuel system includes replacing the gasoline filter element, cleaning the carburetor or fuel nozzle and the fuel supply pipeline. In the process of fuel supply to the combustion chamber through the oil circuit, it will inevitably form gum and carbon deposits, which will be deposited in the oil channel, carburetor, fuel injector and combustion chamber, interfering with the flow of fuel, destroying the normal air-fuel ratio, making the fuel atomized poorly, causing performance problems such as engine wheezing, detonation, unstable idling, and poor acceleration.

7. Rust and scaling of the water tank: Rust and scaling of the engine water tank are common problems.

Hope mine can help you, hope!

Summary. If the abnormal noise occurs when the engine accelerates sharply, the sound will still exist when maintaining high-speed operation. The reasons for the sound are:

The connecting rod bearing is loose, the bearing is fused or the size does not match and rotates; loose crankshaft bearing or bearing burning capacity; The piston pin is broken; The crankshaft is broken. When a cylinder is fired, the sound is aggravated, or there is no sound at the beginning, but there is a sound at this time. The reasons for the sound are:

The copper sleeve of the piston pin is loose; The piston skirt cone is too large; piston pin out; The connecting rod bearing cover fixing bolt is too loose or even the connecting rod bearing alloy is burned and melted off; The flywheel retaining bolts are too loose.

11 Chevrolet Jingcheng idling heard the sound of the engine burning oil is what the problem is.

Hello dear, I am very happy to answer for you, and I will sort out the reply for you as follows: 11 letters back to Chevrolet Jingcheng idling heard the sound of the engine burning oil is not finished because the gap between the piston and the cylinder wall is too large; The piston pin assembly is too tight or the connecting rod bearing is assembled too tightly; The gap between the tappet and its guide hole is too large; The profile of the valve cam is worn; Sometimes, the starter grip comes loose and the pulley makes a sound (noticeable when the speed changes).

Dear, if the abnormal noise occurs when the engine accelerates sharply, the sound will still exist when maintaining high-speed operation. The reasons for the sound are: the connecting rod bearing is loose, the bearing is burned or the size does not match and rotates; The crankshaft imitates the loose bearing or the bearing burning capacity; piston pins break sock teasing; The crankshaft is broken.

When a cylinder is fired, the sound is aggravated, or there is no sound at the beginning, but there is a sound at this time. The reasons for the sound are: the piston pin copper sleeve is loose; The piston skirt cone is too large; piston pin out; The connecting rod bearing cover fixing bolt is too loose or even the connecting rod bearing alloy is burned and melted off; The flywheel retaining bolts are too loose.

The engine is new and changed last year.

Understand that the new engine force may also cause the gap between the piston and the cylinder to be too large, and the detonation is an abnormal burning phenomenon in the engine. When the piston is in the compression stroke, the piston knows that it runs upwards to compress the combustible mixture, at which point the pressure and temperature of the combustible mixture rise.

How to deal with this problem.

There are many factors on the market because the gap between the piston and the cylinder is too large, it is recommended that you have an empty wheel to go to the Labi Tsai 4S shop to overhaul the engine to ensure normal use.

Will the new hair head be like this?

This problem needs to go to the 4S shop for overhaul, because the engine is an important component of the car, and it is also the most parts.

Dear, the new engine will also have a similar situation, because you are at idle speed this kind of high finger is obvious, generally caused by the piston and cylinder clearance is too large, this is also easier to deal with.

Summary. Hello, is the oil pressure too low If the other speeds are normal, then it may be because the rotor clearance is too large, or the pressure relief valve is too small.

Hello, is the oil pressure too low If the other speeds are normal, then it may be because the rotor clearance is too large, or the pressure relief valve is too small.

This is the pressure measured when my new engine is idling, is this pressure normal?

Stress is normal.

Faulty oil lamp line.

Summary. The water temperature needs to reach 80 degrees Celsius, and the 1800cc model should be more than kilogram at idle, and the 2000cc model should be more than kilogram. The driving oil pressure is within the range.

The water temperature needs to reach 80 degrees of Pon's jujube, and the 1800cc model should be more than kilogram in the idle state, and the 2000cc model should be more than kilogram. The driving oil pressure is within the range. Transporting old oaks.

My engine is newly replaced, the oil light is on when idling, and the oil light goes out after a thousand refueling. Is it normal to measure the oil pressure at idling?

It is normal not to drive this, but to drive at least.

Also normal. In this case, it is necessary to consider:1

What is the quality of engine oil sales? If the oil quality of the oil is poor, is the liquid level within the normal range? When the speed of the oil pump is low, it will cause the oil pressure to be low; 2.

The oil pump is aging, the pump oil capacity is reduced, and the speed needs to be increased to increase the pump oil capacity; 3.The gap between the lubricating surfaces is abnormal, which causes serious pressure relief.

These problems can occur under normal stress, huh?

Have you seen these three?

Summary. This kind of oil is generally used with 5w40. It is also written on this manual, you can check it again.

Explanation of engine oil label: W stands for winter, and the higher the number in front of it, the better the low temperature fluidity of the engine oil, which means that the lower the ambient temperature available for use, and the better the protection ability of the engine during cold start. The number in front of w represents the freezing point, and 0w is -35; 5w is -30; 10W is -25; 15W is -20; 20W is -15; 25W is -10.

The number after w represents the kinematic viscosity of the oil at 100, the higher the value, the higher the viscosity and the better the protection at high temperatures. It can also be understood as representing the stability performance of the oil at high temperature (i.e., the possibility of thinning), and the higher the value, the better the stability of the oil at high temperature.

Chevrolet Jingcheng idle oil pressure.

Hello, is the oil pressure too low, if the other speeds are normal, then it may be because the rotor clearance is too large, or the pressure relief valve is too small.

This is measured at idle, is it normal oil pressure?

Hello, this is abnormal, low, normal should be around 200.

You're about 130.

The engine is new.

If you're new to the engine, the biggest possibility is that the oil is too thin.

The low oil pressure may be due to the following reasons: 1. The oil pump is faulty. 2. The normal crack surface of the inner glaze of the crankcase is too low.

3. The oil does not meet the requirements, and the viscosity is too low, that is, the oil is too thin. Among them, the most common is because the oil does not meet the requirements and the viscosity is too low, resulting in the oil being too thin.

What is the viscosity of the engine oil used for this model?

This kind of oil is generally used with 5w40. It is also written on this manual, you can check it again. Oil Labeling Explained:

W stands for winter (winter), and the number in front of it is the better the low temperature fluidity of the engine oil, which means that the lower the ambient temperature available for use, and the better the protection ability of the engine during cold start. The number in front of w represents the freezing point, and 0w is -35; 5w is -30; 10W is -25; 15W is -20 which is bad; 20W is -15; 25W is -10. The number after w represents the kinematic viscosity of the oil at 100, the higher the value, the higher the viscosity and the better the protection at high temperatures.

It can also be understood as representing the stability performance of the oil at high temperature (i.e., the possibility of thinning), and the higher the value, the better the stability of the oil at high temperature.

Summary. Hello, this kind of wow reason is generally that there is a problem with the gasoline pump, and the pump oil is not smooth, so it leads to the situation you mentioned, please check the gasoline pump.

12 automatic Chevrolet Jingcheng, after the overhaul of the high temperature, the idle speed of the cold car is unstable after starting, and the accelerator or start will turn off, but it is difficult to start after the bird opens, and it is necessary to step on the accelerator many times to start what is the reason.

Hello, this kind of wow reason is generally that there is a problem with the gasoline pump, and the pump oil is not smooth, so it leads to the situation you mentioned, please check the gasoline pump.

The petrol pump is new.

Since the appearance of the high-temperature overhaul, I have changed several repair shops, and I have not been able to find the reason.

It was the engine that was overhauled.

Yes, this happened only after the overhaul of the engine, the fuel injector carbon deposits were cleaned, and the timing belt was adjusted. The gasoline pump was also replaced.

It is very likely that the gasoline pump is not very well connected to the engine, and the oil pipe in the middle is bent.

The gasoline filter also has to be replaced.

If it has been overhauled, it is better to replace it.

In addition, there is also the failure of the buffer pad of the Chevrolet Jingcheng 6AT transmission, which is another common problem of the Chevrolet Jingcheng 6AT transmission. Again, local bends are more frequent between 08-15 years. The main reason is that the material used for the buffer plate in the early days of the empty cherry blossom is not good, and the toughness is poor, and after the Chevrolet Jingcheng 6AT gearbox has traveled a certain number of kilometers, it is about 70,000 to 180,000 meters in the bucket thicket, which is prone to damage and fracture of the buffer plate.

Changing to an improved buffer can reduce the recurrence of buffer failure.

Dear, the oil leakage of the Chevrolet Jingcheng 6AT transmission is mainly caused by the damage of the oil seal or gasket. Replacing the damaged oil pump and sealing ring can completely imitate the cheat and solve the problem of oil leakage in the Chevrolet Jingcheng rolling block 6AT gearbox. <>

After driving more than 10 kilometers, the sound will become louder, the strength will become smaller, and it will shake again.

Kiss, the car will be louder after driving more than ten kilometers, the strength will become smaller, and the reasons why it will shake are as follows, 1The failure of the Yinling machine is caused by problems such as ignition system, fuel system, cylinder pressure, etcTransmission failure is caused by problems such as the transmission oil not being able to read the big enough and the internal parts of the transmission being damaged.

3.Tire problems are caused by insufficient tire pressure and uneven tire wear.
