What are the reasons for the burning tile of the Sutar 1 4t engine?

Hello dear! Engine continuous.

Burn tiles. It refers to the phenomenon that the engine burns tiles for some reason, and works soon after maintenance, and even occurs when the tiles are tested after repair. The direct cause of continuous tile burning of the engine is improper maintenance and use, mainly the following points:

1. The crankshaft is deformed and damaged after the tile is burned, and the maintenance is not corrected as required.

Regrinding. When the engine burns the tile and holds the shaft, it runs at high speed.

Crank linkage mechanism.

Under severe braking, the crankshaft is very prone to bending and torsional deformation; At the same time, the surface of the axial continent is also affected.

Ablation. Scratches, loss of returns, scratches and other damage of different degrees. Repairs are carried out without inspection, correction and regrinding, but simply by replacement.

Bearing. It will be due to the crankshaft of each main shaft and the top of the connecting rod shaft.

Concentricity. Out-of-tolerance.

as well as bearings with.

Journals. Improper mating relationship leads to continuous tile burning. Therefore, after burning the tile, it is necessary to carefully inspect and grind, correct the crankshaft, and select the bearing in strict accordance with the repair size. 2. After burning the tile, the dirty and deteriorated lubricating oil was not replaced.

In order to save money, some drivers use dirty and deteriorated lubricating oil for a long time, and the engine crankshaft bearing is not well lubricated and burns tiles. After the tile is burned, the impurities such as metal grinding chips in the lubricating oil increase, and if it is not replaced in time, continuous tile burning will occur. Therefore, after burning the tile, be sure to check it.

Oil pan. The quality of the lubricating oil, if it has deteriorated, it should be replaced with a new oil; If it has not deteriorated, the original lubricating oil should be released, and it should be precipitated and filtered for later use. I hope mine can help you, please set it up! Thank you!

Hello. 1. The oil pump is faulty 2, the oil model does not match, the oil quality is unqualified 3, and the parts are not assembled in place, I hope it can help you.

Sutar 1,4t engine:

1) Fuel saving, when driving in the city, the fuel consumption is more than 8 o'clock in the summer when the air conditioner is fully turned on, and more than 9 o'clock when it is high.

2) The engine is not a simple small displacement turbocharged engine, it does not only rely on a small turbine to increase the air intake, the most critical factor in this - "direct injection in the cylinder" plays a vital role. The direct injection technology injects fuel directly into the combustion chamber of the engine, which greatly improves the fuel utilization, and combined with turbocharging, it squeezes out more power than the naturally aspirated engine on this small displacement engine, while maintaining the fuel consumption at the level of the engine. The displacement of the engine is only, but in high-power operation, in order to maintain the stable operation of the engine, when running at high speed (the speed is more than 140 miles), the fuel injection will be appropriately increased, that is, the fuel injection is a little more than that of the naturally aspirated engine, but it is still much lower than that of the naturally aspirated.

3) The engine is based on the Volkswagen EA111 series engine, so the maintenance cost is lower than those developed based on the EA888 series engine. Small maintenance costs less than 500 yuan, large maintenance depends on the condition of the car, the cost is between 900 and 1300 yuan, the first warranty is free.

The advantages of the Sutar 1,4t are:

1) The power is good, the speed is fast, and 2) the stereo sound of the car is very good.

3) The trunk is huge.

4) Fuel saving. Disadvantages of Sutar 1,4T:

1) The power is too good for novices.

2) After driving for a while, the engine will be hot.

3) Somewhat expensive.

The 2014 Sutar is very powerful, and it is equipped with an advanced engine, which is used on the Golf and Magotan engines. The engine uses advanced direct injection and turbocharging technology to output up to 96kW of maximum power, and can output a maximum torque of 220Nm at a low speed of 1750 rpm.

"Burning pads hug shafts", "watts", in fact, are the general name of crankshaft bearings and connecting rod bearings, which play the function of bearings and have oil channels or oil holes. The "shaft" is the crankshaft, the core component of the engine, which converts all the work into rotational force and outputs it through the flywheel.

"Burning tile shaft" is the most serious mechanical failure of the engine, although the causes are different, but the fundamental result is that the engine crankshaft and the large tile, small tile due to the lack of oil film protection and serious dry grinding, the contact surface reaches the extreme high temperature, the crankshaft journal and the size of the tile sinter, melt, bite each other, resulting in the engine can not rotate. There are mechanical failures and man-made reasons for this phenomenon, and there are mainly several possibilities:

1. Heavy load operation during cold start, the oil has not been lubricated to the bearing pad in a viscous state at low temperature, and the surface of the bearing has formed an instantaneous high temperature due to the large load, resulting in mutual melting and locking of metals;

2. If the engine is used for a long time, with the increase of normal wear, it will lead to the increase of the bearing gap, and there will be obvious tile sound, which will lead to the loss of oil and pressure relief in the middle of the engine, and the insufficient oil supply between the bearings, forming a high temperature, resulting in melting and locking;

3. Lack of cooling water or long-term high-temperature driving, the oil temperature rises rapidly, loses viscosity, and can not form a protective oil film on the surface of the shaft and the pad, resulting in serious friction and melting;

4. The oil supply pressure of the oil pump is reduced, and it is difficult for the oil to reach the designated lubrication position with the standard pressure. The oil filter screen and oil passage are blocked by impurities, so that the oil leading to the crankshaft is blocked, and the oil pipeline leaks, resulting in the pressure of the lubrication system dropping, resulting in the dry grinding of the bearing pad;

5. Due to various reasons such as oil-water collusion of cylinder head gasket, water jacket corrosion, poor atomization of gasoline, etc., the oil and water, the oil and gasoline are mixed, which destroys the oil composition or dilutes the oil, and will also cause "burning tile and holding shaft";

6. The indiscriminate use of various oil additives destroys the molecular structure of the engine oil, resulting in the slow and dilute flow rate of the engine oil in the oil channel, and the reduction of lubrication function, which will also lead to the locking of the bearing;

7. If the oil is not changed for a long time, the use of fake engine oil will produce "burning tile and holding shaft".

For car owners, when encountering oil lamp alarm, water temperature is too high, do not continue to drive when the fault can not be determined, it is best to call the maintenance station as soon as possible to avoid greater losses.

Hello, in this case, you have to go to the repair shop to overhaul the engine, replace the ZWD and cylinder liners, and the maintenance cost is more expensive.

Only the tile can be changed. If it's bad, the crankshaft has to be replaced.

The oil doesn't work, or it doesn't have enough, or the oil pump doesn't work.

It is estimated that the engine is worn out and the gap between the piston and the cylinder block is large.

The all-new Sutar series models are equipped with three types of naturally aspirated engines, allowing consumers to have more choices. The naturally aspirated 4-cylinder engine technology of the new Sutar is very mature, with 4 valves per cylinder, and the intake and exhaust of each cylinder are smoother than the previous generation of 2-valve engines, with low-rpm torque and high-speed 800 Tomb Plus Xingrong 7

You're right. Your Sutar is.

Yes. It's the same engine as the Jetta.

Hehe. No.

Strange...And.

Most car owners reflect.

The car was on the noisy side.

In fact, the quality is still good.

There is no such thing as a perfect car.

Don't take it too seriously.

Brother. of 110 horsepower.

The boost peak is 130 horsepower.

Usually less than 90 horsepower.

The gap is not big. A light step on the accelerator.

It's better than stepping on the accelerator to death.

1. If it means that the sound is loud when it is just started, the reason may be that the water temperature is low when starting, and the engine will automatically increase by several hundred revolutions to accelerate the rise of the water temperature, and it will generally return to the normal speed within a few minutes, and the sound will also fall;

2. If the sound has been quite loud, depending on what car the landlord is comparing with, the new Suteng engine compartment should have no soundproof cotton;

3. If it is other.

It may be that the clutch pressure plate is broken. I said probably, check it out. Is it fast on the speed and slow on the speedometer?
