What is the reason for the engine horizontal bar tile

Lack of cleanliness or low oil pressure, clogged oil passages!!

It should be "hugging tiles".

More than 95% of the causes of "burning tile and shaft" in automobiles are mechanical failures, usually due to:

1. The quality of the crankshaft and the tile is not good, the finish of the journal and the tile surface is poor, especially the overhaul of the vehicle that has replaced the bearing pad, the work of grinding the shaft scraping tile in the overhaul is not fine enough, after the tile, the shaft and the tile are not well matched, the contact surface is too small to form an oil film, and there is a gap on the back of the tile, the alloy and the tile can not be completely tightly fitted and loosened to go to the outer circle, which blocks the oil hole and causes the oil supply to be interrupted to form dry friction.

2. Incorrect installation of large and small tiles, improper clearance adjustment, and too large or too small contact area will make it difficult to form an oil film on the contact surface between the shaft and the pad. Sometimes the torque of the fastening bolt of the bearing is too small, which causes the bearing to loosen for a long time, and also causes the gap to change and affect the lubrication.

3. The gear of the oil pump is seriously worn and failed, the oil supply pressure is reduced, and the oil is difficult to reach the designated lubrication position, resulting in dry friction of the bearing.

4. The oil channel is blocked by unclean impurities, which blocks the oil leading to the crankshaft and forms dry friction of the bearing.

5. The oil pipeline leaks, the pressure of the oil circulation system drops, and the oil is difficult to reach the designated lubrication position, forming dry friction of the bearing.

6. When the cold car starts, the throttle is slammed, and the oil has not yet been pumped to the bearing pad in a viscous state at low temperature, and the surface of the bearing has formed an instantaneous high temperature, causing the metal to burn each other.

7. The engine is seriously overloaded, and there is a long-term low-speed and high-torque working condition, because the oil pump speed is also low when the engine speed is low, and the oil supply is insufficient, but the high temperature is formed between the shaft and the tile, resulting in locking.

The above-mentioned mechanical problems are the main cause of "burning pads and holding shafts", and there are only 3 special situations that may cause serious bearing failures due to oil factors.

1. Due to the infiltration of cooling water into the engine oil, the oil will emulsify and deteriorate for a long time, and the viscosity will be completely lost, and the oil film can not be formed on the surface of the shaft and the pad, resulting in serious dry friction.

2. The engine temperature is too low in winter, so that the fuel atomization is not good, and the incomplete combustion makes the fuel flow into the oil bottom along the cylinder wall and dilutes the lubricating oil, which will also cause "burning tiles and holding the shaft".

3. The use of oil with too high viscosity and high pour point in the severe cold season, or indiscriminately mixing a large number of additives containing viscosity into the engine oil, may cause the oil to flow too slowly in the oil channel, and cannot be pumped to the bearing on time, resulting in dry friction between the bearings.

It should be called a tile, which is caused by poor lubrication.

It should be "hugging the tile" or "hugging the shaft", as the name suggests, it is the tile "hugging, hugging" the axis. It could be a crankshaft, it could be a camshaft.

The main reasons for the occurrence of axle holding in private cars are: 1The oil is not clean, there are various impurities, and small particles wear out the polished surface of the tile when the shaft rotates at high speed (regardless of the installation of the tile or the poor processing of the oil duct).

2.After changing the engine oil or cooling the car, you can blast the oil wildly. When the oil pump hasn't pumped up for a short time - if it's a private car, it should be a rare occurrence.

Private cars should probably pay attention to these two points, and other possibilities are not allowed.

If it's learning. The 2nd floor is well reproduced

It's been 4 years, it's long overdue to maintain and repair Check whether the cylinder, piston, and piston ring are seriously worn, and the consequence is to burn oil or lack of power, and then check whether the valve guide is worn and replaced in time.

The oil in the water tank is caused by the aging of the cylinder sealing rubber ring and needs to be replaced.

.The service life of this kind of car is only two to three years, and it is recommended that you change to a truck, such a garbage three-wheeled one, you are still a baby???

It may be that the cylinder gasket is damaged, just change the four sets, and the condition of the car is almost the same as new.

It's been four years, if you don't have a business or you're a master, otherwise the single-cylinder engine won't last that long. I am a repairman, for your situation I think the wear is serious, I suggest you go to the repair shop to do a medium repair, change to a six-set, charter oil salary of 400 yuan is enough. There are several reasons why there is oil in the water now:

The water-blocking ring of the cylinder liner is broken. The head gasket flushed. There are cracks in the body.

Cylinder head plugging piece piercing.

Like the ordinary one, the car is very weak, so it is recommended not to buy it.

The single-cylinder Zongshen 250 is estimated to be about 17,000 yuan, and the single-cylinder is not as good as the double-cylinder, but it is much stronger than ordinary motorcycles such as 125 and 150.

All engines can be converted from oil to gas, but diesel engines require a small amount of oil (for ignition), and any engine gas oil is sucked through the suction tract of the engine. If a gasoline engine burns liquefied petroleum gas, the pressure is reduced to 10 mm of water. Inhalation of combustible gas by the engine.

Horizontal bar? Parallel bars, are you talking about gymnastics?

I know single-cylinder, multi-cylinder.

80% of the cars on the market are in-line 4-cylinders, a few are V6, V8, V12, and sports cars have W16 (the number is the number of cylinders).

A single-cylinder engine with a large flywheel is a tractor engine.

The car has 4 cylinders at most.

Not single-cylinder power! The 480 engine in front of the 4 represents 4 sets of cylinders, and 80 means that each cylinder bore is 80 mm! Generally, single-cylinder power on vehicles is only used for agricultural vehicles and motorcycles!

No, it's a four-cylinder, and the cylinder diameter is 80 mm.
