What is the brand of Weichai 4105 original fuel injector

Weichai 6200 fuel injector is a fuel injection equipment produced by Weichai Power Co., Ltd. The model suitable for Weichai engine is 62008200. This fuel injection nozzle model is widely used in Weichai series engines, especially in the field of heavy trucks and construction machinery.

Which is better, Dongfanghong or Yuchai? Personally, I think Yuchai is better. Yuchai is a designated manufacturer of national 105 models. After decades of development and absorption of international advanced technology, Yuchai machines are different from the past.

Yes. Weichai 430 horsepower is a high-performance engine. The engine is equipped with a horizontal nozzle gun and can be adjusted, so the amount of fuel injection can be adjusted.

First, remove the Weichai fuel injector. Then wipe it clean. Finally, the operation can be completed by having the information model on the solenoid valve of the fuel injector or at the flat installation position.

However, compared with the fuel consumption (fuel consumption per unit of power time), the 4105 is expanded on the basis of 4102, but the reliability can stand the test. Yangchai's 4105 machine can be said to be a unique in the national engine market. Yunnedwei F40E is not bought by many people, and the load capacity of 15 tons is also good.

What to do if the Weifang 4105 diesel engine burns the engine oil

You first check whether the air is too dirty. If the air filter is too dirty, it will cause the engine oil to burn upwards through the piston ring. It is recommended that you clean the air filter every week to ensure that the air intake is smooth; check or replace the four accessories, check the valve oil seal, the gap between the valve and the duct, replace the high-quality oil, etc.

Avoid burning oil: If there is a slight oil burning, the continued use of unqualified lubricating oil is likely to lead to increased wear. At this time, the moderate use of high-quality lubricating oil can effectively alleviate the problem of engine oil burning while reducing the wear of the engine during operation. The use of high-viscosity oil can also enhance the sealing performance of the cylinder.

Solution: Don't worry if there is oil burning, take the right medicine. As long as the carbon accumulation problem of the piston ring is solved, there is no need for overhaul, and the problem of burning oil can be directly repaired.

In this case, it is recommended that car owners can choose PNF oil additives or fuel additive repair agents, which can increase the viscosity of the oil. In addition, high-quality oil should also be selected in the selection of oil, which can have a better effect on the situation of slight oil burning.

The choice of engine oil. If there is a slight burning phenomenon of engine oil, the continued use of lubricating oil that does not meet the requirements is likely to lead to aggravation of wear. At this time, the moderate use of high-quality lubricating oil can reduce the wear of the engine during operation and effectively alleviate the problem of burning engine oil, and the use of high-viscosity oil can also Enhance the tightness of the cylinder.

How many horsepower does the 4105 diesel engine have

1. The engine is 150 horsepower, 4 represents the number of engine cylinders, and 105 represents the diameter of the cylinder. Main technical parameters Model ZH4105Y4-5. Total displacement of piston: 7L. Standard power: 50/4000. Cooling method: forced water cooling. Start-up method: electric start-up.

2. The horsepower of most 4105 engines is about 150 horsepower. Horsepower can be converted into a success rate, and power is used to measure how much work the engine does per unit time. The higher the power, the stronger the engine performance, but the higher the power, the higher the fuel consumption of the engine. The power of the engine is inseparable from the speed and torque.

3. The engine has 100 horsepower. 1 horsepower is about 735 watts. Horsepower generally refers to metric horsepower rather than electric horsepower. 1 horsepower is equivalent to completing the work of 75 kilograms in 1 second, which is also equal to 0.735 kilowatts, or meter horsepower.

Dongfanghong 4105 engine parameters

1. It should be noted that there are generally some letters after "4105". To distinguish different models of engines. Such as QB, etc. 105X12 speed 2000 r65 horsepower. 105X12 rns 2200 rn 72 horsepower. 105 X 130. The speed is 2200 r.75 horsepower. The cylinder diameter is the same, which is distinguished by the piston stroke, rotation speed and supercharging.

2. Cylinder engine.105 cylinder diameter. Specifically, you need to calculate the exhaust volume to get the itinerary. You can give me the machine model or the exhaust volume. 105×105×115×0.7854÷1000=997CC (single cylinder exhaust volume) 997CC×4=983 (this is for your reference) You can calculate it according to my method.

3. L is the abbreviation of Luoyang, the place of origin. R is the British Ricardo technology used. C means that the stroke is 135mm. If there is no c, it is the stroke of 125 or 120mm. 4 or 6 is the number of cylinders. A indicates the cylinder diameter 105mm. B is 108mm. M is 110mm. In the back, Z is the supercharged type, L is the supercharged medium-cooled type, T is for tractors, and G is for construction machinery.

What is the reason why the Weifang r4105 diesel engine can't be started

1. The diesel filter is seriously blocked, the oil supply is seriously insufficient, and it often turns off automatically, and it is difficult to start again after turning off. The fuel injector is seriously worn, and the high-pressure gas in the cylinder enters the oil pipeline through the fuel injector through the return oil pipe, forming a gas resistance, preventing the oil supply and causing difficulties in starting.

2. The fault may be that there is air or water in the fuel system, or the temperature is too low and the diesel is too sticky. It is also possible that the injection time of the fuel injector is too early or too late. These reasons may make it difficult or unable to start the diesel engine. If the diesel engine is not easy to start, you can check each pipeline to see if the joints are not strict.

3. The oil supply angle is too small, and the oil supply is pushed at all times.Late, or even miss the highest compression pressure point in the cylinder (that is, after running to the upper compression stop point), which will cause signs such as difficult diesel to ignite, incomplete combustion, difficult start-up, insufficient power, and black smoke from the exhaust pipe.

4. After the Weifang diesel engine presses the start button, the unit does not reflect or rotates slowly. What's the matter? What's the solution? The battery is low. Solution: Check the battery charge. The battery wire and plug are loose. Solution: Check and fasten the battery cable and plug. The intermediate relay failed.

5. There are two main reasons why it is difficult to start due to diesel engine failure: 1. The starting resistance moment is too large. In addition to the oil is too sticky due to the low temperature, the main reason why the rotation resistance torque of the diesel engine is too large is the sintering of the main bearing and connecting rod bearing, or the piston pin is bitten and the piston ring is broken. Cause pulling the tank, etc.
