How to disassemble and install the electronic oil pump of Weichai Guosan engine?

Before disassembly, push the roller back and forth by hand to check whether the roller (and the upright and the top rod pair) and the piston are stuck, and whether the stroke is too small.

The installation of the fuel injection pump of each diesel engine is very different. It depends on the specific model of the diesel engine, mark it when disassembling, or record it, and install it according to the mark or video when installing.

The disassembly method of the oil pump is as follows: disconnect the negative wire of the battery. Remove the engine timing belt and take out the crankshaft timing belt wheel. Remove the generator and the generator bracket. Remove the compressor and compressor bracket. Remove the oil sup and the oil pump filter. Remove the oil pump drive chain tensioner and guide plate.

Is the size of the 320 of Weichai engine Guosan the same as the size of 290?

The power and horsepower are different. According to the query, Truck Home shows. The maximum output power of Weichai 290 is 213 kilowatts, the maximum output power of Weichai 340 is 250 kilowatts, and the power of Weichai 340 is greater. The maximum horsepower of Weichai 290 is 290 horsepower, the maximum horsepower of Weichai 340 is 2340 horsepower, and Weichai 340 horsepower is even greater.

The fuel is similar, mainly because the power and displacement are different, and the engine cylinder diameter and length are different.

Know Xiaoyou Jianshu's answerer Answer volume: 657 Adoption rate: 0% Helper: 3.45 million I also go to answer the question and visit my personal page. Follow and expand all, that is, there is a difference in the size of the supercharger impeller, and the combustion chamber of the piston is different. Everything else can be used.

Weichai 270 horsepower has Weichai Deutz and Weichai Power. The models are WP270 and WP270 respectively, which are 6-liter and 10-liter respectively.

Is it normal that the speed of Guosan Weichai engine is only 1700?

1. The maximum speed of Weichai engine is generally about 2,500 rpm.Weichai power generator set refers to the production of Weichai Heavy Machinery (Weifang) Power Generation Equipment Co., Ltd., a wholly-owned subsidiary of Shandong Weichai Holding Group. It uses the engine independently developed and produced by Weichai Group, supporting well-known brand generators, and the unit is manufactured and tested to implement the GB/T2820 standard.

2. Up to 2600 turns per minute is normal. Speed is one of the important indicators of the working state of the engine. Too high or too low speed has a negative impact on the performance and life of the engine. Therefore, the 500 horsepower speed of the Weichai marine engine is 1500 to 2600 rmong per minute. It can reduce the damage to the engine and make the engine last longer.

3. If the engine of Weichai is at 1700 rpm, the speed keeps falling down as soon as it reaches the slope,This is quite normal, because you should slow down when going uphill. Your gear must be too high.

4. Abnormal. It is normal for the maximum speed of Weichai 245 engine to reach 2200 to 2500, so it is abnormal to only reach 1200.

Weichai 160-horsepower Guosan engine is blocked by water?

The damage of the oil radiator causes water to enter the oil. The oil radiator is damaged, the radiator tube is broken, and the water outside the radiator will seep into the inside of the oil radiator, causing the oil to enter the water; the engine blocked water leakage causes the oil to enter water. The engine is blocked and leaking.

The main reason for the oil inletting in Weichai engine: the damage to the oil radiator leads to oil inletting water.The oil radiator is damaged. The radiator pipe is broken, and the water outside the radiator will penetrate into the oil radiator, resulting in oil inlet. The engine water is blocked and leaks, causing the oil to enter water.

It's not very clear. No matter what kind of engine it is, if you are talking about water entering the oil chamber, most of them are damaged by the cylinder pad. Check whether the water tank has gas sprayed out, and if there is, it may be a cylinder edge off the line.

Weichai Guosan electric injection engine camshaft and crankshaft synchronization error

The mismatch of the camshaft and crankshaft speed signal is usually due to camshaft and crankshaft speed synchronization signal error or engine control route Caused by malfunction. It may also be a problem with the camshaft position sensor and crankshaft position sensor, or the timing misalignment and jumping teeth.If the engine runs normally, the car can continue to drive.

The problem is generally caused by the incorrect synchronization signal of the camshaft and crankshaft speed or the failure of the engine control route. It may also be a problem of the camshaft position sensor and crankshaft position sensor, and it is also necessary to check the timing misalignment jump teeth. The camshaft is a component of the piston engine. Its function is to control the opening and closing of the valve.

This problem shows that the quality of the flywheel is not up to standard, because the signal disk of the crankshaft position sensor is with the flywheel. After the replacement, because there is a slight deviation in the position, the computer detects that the signal generated by the crankshaft position sensor is not synchronized with the camshaft.

The installation of the engine crankshaft and the position of the camshaft are unreasonable. It is recommended that you take it apart again and put it back: the most important part in the engine.

The unreasonable position of the camshaft relative to the crankshaft installation may be due to the fact that the timing mark is not aligned or the timing belt is loose. Just aim at the timing mark or tighten the belt. There is a certain proportional relationship between the crankshaft angle of the engine (gasoline engine) and the camshaft angle; this relationship is called "gas distribution phase".

At this time, the camshaft is usually located on the side of the crankcase, and the valve can be adjusted through the gas distribution mechanism (such as the lever, putter, rocker arm, etc.). Therefore, most bottom camshafts are also called side camshafts.

Which classic is Guosan Weichai

1. The steps of Guosan Weichai 380 are as follows. Guosan Weichai 380 has strong performance and long service life, and Guosan Weichai 380 has better horsepower.Guosan Weichai 380 is of good quality, cost-effective, and good after-sales service.

2. OK. Guosan Weichai 380 has stronger performance and long service life, while 400 has a longer service life than 380, but its performance is not as strong as 380, so Weichai 380 is better.

3. If this question was really 20 years ago, I would have answered your big firewood. Because it is an imitation of the Deutz engine, the throttle is very hard, but it is not easy to turn off the engine.

4. However, although Weichai's sales volume is second only to Yuchai's, its sales volume has exceeded that of Dongfeng Cummins.

5. The performance is almost the same: the Weichai national 3 engine is generally wp10, and the national 4 engine is generally wp10N series. The structure of the two is almost the same, but Country 4 adds a SCR exhaust post-treatment system on the basis of Country 3, and its emission standards are higher.
