Owei 11-liter engine cylinderHow to disassemble the sleeve

If you want to remove it, you need to remove the oil pan shell with a tool, remove the cylinder head, and then remove it from the lower part of the cylinder with a special tool. Use a screwdriver, that is, a screwdriver. Chisel slowly, and then the cylinder liner will fall out of the oil sap. When the cylinder liner is inserted into the engine cylinder block for the first time, there is no cylinder liner.

First, disassemble the external parts of the engine, such as the cooling system, the intake system and the exhaust system. Secondly, remove the valve chamber cover and the rocker arm shaft cover. Then remove the cylinder head bolt and remove the cylinder head from the engine. Then find the timing mark of the crankshaft and camshaft and make sure to align.

Does the questioner want to ask "How to time the 11-liter cylinder head of Owei"? First, remove the valve cover and find the upper and lower stop engraving lines on the circumference of the crankshaft pulley.

After disassembling the engine, you can replace the cylinder liner, among which the wet cylinder liner is easier to take. You can take it out without tools, and then directly replace the matching cylinder liner.

It is best to use special tools when disassembly; bolts should be disassembled in order to prevent breakage or deformation during disassembly; after the engine decomposition, special tools should be used to test each part and carried out according to the maintenance manual; for abnormal sounds, burning oil trucks, after removing the cylinder head, pay attention to check whether the multi-cylinder liner is pulled Tank.

Remove the cylinder head fixing screw, and note that the screw should be crossed and loosened from both ends to the middle. 2) Remove the cylinder cushion and pay attention to the installation direction of the cylinder cushion. 3) Flip the engine and remove the oil span fixing screw (note that the screw should also be loosened from both ends to the middle). 4) Remove the oil span and oil spat.

How to adjust the valve gap of Owei eleven liters 390 horsepower

1. Loosen the screw fixing the rocker arm of the Orway engine. The nut on the top of the valve of the Orway engine can be loosened, and there is no need to screw it down. Use a flat screwdriver to loosen the screw that adjusts the valve gap of the Orway engine.

2. The first method of adjusting the engine valve gap is the cylinder-by-cylinder adjustment method. First, loosen the adjustment screw, then tighten the screw shaft with a screwdriver, determine the adjustment position, tighten the ground again, then adjust the gap between the intake port and the exhaust valve, and then gradually adjust the gap between the other valves in each cylinder.

3. The first is the cylinder-by-cylinder adjustment method. First, loosen the adjustment screw, and then use a screwdriver.Tighten the wire shaft, tighten the ground again after determining the adjustment position, and then adjust the gap between the intake and exhaust valves, and then gradually adjust the valve gaps of other cylinders according to this method.

4. The first method of engine valve gap adjustment is cylinder-by-cylinder adjustment. First, loosen the adjustment screw, then tighten the screw shaft with a screwdriver, determine the adjustment position, and then tighten it to the ground. Then, adjust the gap between the intake and exhaust valves, and gradually adjust the gap between the valves of other cylinders according to this method.

What is the right notation of Owei 11-liter 460-horsepower engine

Owei 11-liter 460-horsepower engine timing tooth body matching mark. Jilin Dongguang Aowei Automobile Brake System Co., Ltd., a wholly-owned subsidiary of Northeast Industrial Group under China Weapons Industry Group, was established in 1970. It is a large enterprise dedicated to the production and sales of automobile braking products.

First, align the mark on the crankshaft belt wheel with the external mark, and then align the belt wheel mark on the camshaft with the mark outside the engine. Then put the formal chain on it and install the tensioner in place.

The timing steps for the Owei 11-liter engine disassembly booster pump are as follows. Turn the engine and let the 1 and 6 cylinders reach the upper stop point. Assemble gears other than the camshaft gear, and see that there is a mark on the body, so that the mark of the camshaft gear coincides with this mark. Turn the engine to about 22 degrees at the upper stop.

Check the timing mark of the engine through the detector, check whether the engine's inlet manifold, outgout manifold, crankshaft, connecting rod and drive chain are installed correctly, and check whether the engine's timing mark is correct.

Generally, there is an installation mark on the side of one of the teeth of the timing gear. There are three such marks on the idle gear, two of which are adjacent. During installation, the two notation clips on the idle wheel are a mark on the timing gear, and there are two adjacent marks on the gas distribution gear, which are also aimed at the other on the iddler. Just make a mark.

Which side of the valve spring of the 11-liter 420 horsepower engine of Auwei has a double spring?

1. The spring of the Orway horsepower engine has a double spring. Check whether there is any abnormal noise, and learn to distinguish the abnormal noise that belongs to the reasonable noise. It is difficult for ordinary car owners to distinguish which are faulty abnormal noises and which are reasonable abnormal noises. When I went to the repair shop to test the abnormal sound of the vehicles, only nearly 20% of the vehicles really had problems.

2. The valve spring generally does not need to be divided, but it is up and down. If you install it more precisely, it should be divided. If you look closely, one side of the spring should be denser. The direction of the tight down is fine. The function of the valve spring: The valve spring is located between the cylinder head and the valve rod tail spring seat.

3. Generally, it doesn't need to be separated, but if you wear it very precisely, it must be separated. Observe carefully. If there is a spring, it should be denser and lower. The valve spring is located between the cylinder head and the spring seat at the end of the valve rod.

4. The reason for adopting this structure is to prevent the loose closure of the valve due to the resonance caused by the rotation direction of the valve spring, so two valve springs with opposite rotation directions are set to offset the resonance frequency of the two valve springs in reverse, thus eliminating resonance. The curved top of the cam is the vertex of the valve opening.

5. Yuchai four-cylinder engine valve springs are all double-spring designs, because the role of the valve spring in the engine is to bear the weight of the valve and make it rebound. The double-spring design can improve the elasticity and life of the spring, making the engine run more smoothly and reliably.

What is the reason for the sound of Jiefang Auwei 11-liter engine

Mixed gas is too thin: The reason for the failure of the car engine reinition gun may be the failure of the oil line or air intake system: the oil line failure is mainly It is caused by too little fuel injection in the fuel injector. The main reasons for too little fuel injection in the fuel injector are: too low oil pressure; the fuel injector is blocked.

The reasons for the sound are: the gap between the piston and the cylinder wall is too large; the piston pin assembly is too tight or the connecting rod bearing assembly is too tight; the gap between the straight rod and its guide hole is too large; the contour of the gas distribution cam is worn; sometimes, the starting grip is loose and the pulley makes the pulley sound (obvious when the rotation speed changes).

According to your description, there should be two reasons. On the one hand, due to the wrong timing of the ignition, the engine knocks on the cylinder, resulting in a noise.On the other hand, the noise is caused by improper adjustment of the valve rocker arm gap, which is mainly caused by the excessive valve gap.

Reason for engine ignition: If the mixture is too thick, it usually leads to incomplete combustion of the mixture. After being discharged from the exhaust manifold, the high-temperature exhaust manifold is ignited again, resulting in ignition. You can check the pipeline from the fuel tank to the connector of the carburetor. If there is oil leakage or blockage, it should be unblocked or replaced. Or check the gasoline pump.

Owei 11-liter 420 engine power is insufficient

1. Hello, according to your fault analysis, this situation is generally caused by high-pressure pump decompression. You need to read the engine data stream, see below and add The oil track pressure data at the speed time canIt can't reach 850bar. If the data is not enough, you can disassemble the metering unit at the front of the high-pressure pump and blow it.

2. Common problem of Owei 11-liter engine: oil line failure: Generally, when the oil road is blocked, it may cause a slowdown. Insufficient engine power: The output power of the engine itself is insufficient, the output power is lower than the rated power, and the rotation speed is too low. It is also caused by a problem with the main pump.

3. The valve seal is corroded and aging, and the sealing performance is invalid. In addition, there is a crankcase ventilation system (exhaust valve) in the car now. If there is a problem, it will also increase the consumption of oil. In the past, the problem of burning oil could only be solved by disassembly and repair. Now there is a plan to solve the problem of burning engine oil without disassembly and repair, which can be found out through Baidu.

4. The reason for the decrease in engine power;Excessive carbon accumulation in the engine: Excessive carbon accumulation in the valve and intake pipe is the most common reason for engine power loss. Solution: Find a professional auto repair staff to help clean up the accumulated carbon and check whether the spark plug needs to be replaced.
