What should I do if Weichai 340 burns engine oil slightly

The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc., the above reasons will aggravate the oil consumption and lead to the burning of engine oil, making the vehicle appear:

1. Carbon deposition occurs in the combustion chamber, which makes the gas ring of the piston ring stuck, and the sealing is poor.

2. Oil sludge is generated in the lubrication system, and the oil sludge blocks the oil return hole of the oil ring and weakens the oil scraping performance.

3. Wear occurs between the piston and the cylinder wall.

4. The valve seal is corroded and aging, and the sealing performance fails.

In addition, cars now have crankcase ventilation systems (exhaust valves), which can also exacerbate oil consumption if there is a problem.

Summary. Hello, Weichai 430 brush 375 can save fuel, because 430 Weichai is too fuel-intensive, if the car is driving more than 30,000 kilometers, it is recommended to check whether there is too much carbon deposition in the engine, because too much carbon deposition in the car engine may lead to. 430 can be brushed into 375 at most, it will be more fuel-efficient, I hope the above will help you<>

Weichai's new engine oil burning solution.

Hello, I'm helping you sort out the answers to your questions, please wait a moment

If the new engine burns oil, you need to check whether the turbocharger has too large a gap, which causes the oil to burn, if it is not the oil burned by the turbocharger, you need to check whether the valve oil seal is good? Check whether the piston rings are not installed properly or if the quality is faulty.

The oil has a burnt taste.

The engine oil has a burning smell, is there a situation where the car is experiencing high temperatures?

No. If the car does not have high temperatures, the normal engine oil will not have this kind of burning smell, and how much will the engine oil be missing if your car has a maintenance cycle?

Run 5,000 kilometers to burn four liters of oil.

If the car will burn four liters of engine oil after running 5,000 kilometers, has the turbocharger of the engine been checked? Have you ever checked the valve seal of the engine, whether it is not installed in place when the new car is installed? There is also a piston four matching parts of the engine, which he did not install in place.

The car has only run 170,000 kilometers.

The car has only run 170,000 kilometers.

The turbo check is fine, and the lower exhaust isn't big.

This has little to do with the number of kilometers of the car, if there is no problem with the supercharger, the lower exhaust of the engine is not large, then this is the case of the engine's valve seal, and in other places, he will not burn the engine oil so seriously.

Will the piston ring get stuck?

If the piston ring is stuck, it will appear that the lower exhaust of the engine becomes larger, normal, if you fail to check the appearance of the engine supercharger, there is no problem, then the fault phenomenon of burning engine oil is caused by the engine inside one is the valve oil seal, and the other is the piston ring of the engine, and the other will not cause the oil to burn so seriously.

You only need to check the turbocharger of the engine, there is no such phenomenon as burning oil, then you can directly lift the cylinder head and leave the engine unrepaired, which is what happens inside the engine.

If I can help you, please give me a thumbs up Thank you!

Summary. The main reasons for diesel engine oil burning are the following, namely:

1. This is due to the piston ring, especially the oil ring wear or the piston ring counterpart, or the poor elasticity of the ring, the broken ring, and the piston ring is cemented in the ring groove and other reasons caused by the piston ring scraping effect is greatly reduced, so that the oil on the cylinder wall is channeled to the piston top combustion chamber, causing the oil to burn.

2. The diesel engine runs all the time under high temperature and high load, which will cause the wear of the piston ring and the cylinder liner, and cause the oil to burn when the cylinder is pulled.

In order to avoid the phenomenon of diesel engine burning oil, the driver should do the following:

1) Choose the right oil: choose the oil with high viscosity and low volatility, and try to choose the best quality oil of the big brand.

2) New car run-in requirements: car owners should drive carefully during the run-in period. Break-in is carried out according to the requirements of the break-in period.

3) Fuel quality must be qualified: The quality of oil is a major factor causing carbon deposition, and the quality must be guaranteed.

4) Regular maintenance, change the oil, oil filter on time, and replace the air filter in time.

Weichai's new engine oil burning solution.

Hello friend, happy to answer for you! Weichai's new engine burns engine oil. The key places to be inspected are exhaust valves.

Crankshaft ventilation check valve to see if it is damaged. There is also whether the valve seal is damaged. and whether the piston ring is stuck.

Whether or not the piston has a tie rod. Basically, if you exclude the outside, you need to lift the engine, and replace 4 spare sleeves to solve the problem of burning engine oil.

What are the causes of burning engine oil?

The main reasons for burning oil in diesel engines are as follows: 1. This is due to the piston ring, especially the wear of the oil ring or the piston ring counterpart, or the poor elasticity of the ring, the broken ring, and the piston ring is cemented in the ring groove and other reasons caused by the piston ring oil scraping effect is greatly reduced, so that the oil on the cylinder wall is channeled to the combustion chamber at the top of the piston, causing the oil to burn. 2. The diesel engine runs all the time under high temperature and high load, which will cause the wear of the piston ring and the cylinder liner, and cause the oil to burn when the cylinder is pulled.

In order to avoid the phenomenon of diesel engine burning oil, drivers should do: (1) choose the right oil: choose the oil with high viscosity and low volatility, and try to choose the engine oil with the best quality of the big brand.

2) New car run-in requirements: car owners should drive carefully during the run-in period. Break-in is carried out according to the requirements of the break-in period.

3) Fuel quality must be qualified: The quality of oil is a major factor causing carbon deposition, and the quality must be guaranteed. 4) Regular maintenance, change the oil, oil filter on time, and replace the air filter in time.

More than 20,000 kilometers, serious burning of engine oil, manufacturers should be how to solve the user.

If the vehicle is within the warranty scope (the current engine warranty time is at least 3 years and 60,000 kilometers, based on the first arrival), and the maintenance records are complete (the sales and service stores are maintained normally on time), the failure phenomenon caused by non-human operation (oil leakage, lack caused by collision; high engine temperature; Improper dismantling, maintenance, filling of inferior fake engine oil, etc.), of course, you can make a normal claim. With the product quality assurance certificate, you can go to the corresponding sales service store for free maintenance and claim service.

The reason for the oil burning solution of diesel engine is that the gap between the piston ring and the oil ring is too large. Because the lubrication of the piston ring, oil ring and cylinder barrel is lubricated by splashing between the two, and the excess lubricating oil is scraped off by the oil ring. If the gap between the piston ring and the oil ring is too large, a part of the oil will be skewed into the cylinder from the gap, and due to the high temperature in the cylinder, it will burn together with the diesel fuel injected into it, and it will appear as green smoke.

The solution is to replace the piston ring and oil ring. The reason for the oil burning of Weichai engine is that the high temperature causes the cylinder to be pulled, and then the intake pipeline is too dirty, resulting in damage to the valve oil seal and the cylinder, and the treatment method is to replace the four matching and valve oil seals.

The solution to burning diesel engine oil is as follows:1. Choose oil with high viscosity and low volatility, and try to choose a big brand oil with the best quality; 2.

The fuel quality should be qualified; 3.The owner should drive cautiously during the run-in period, and return to the run-in in accordance with the requirements of the run-in period; 4.Change your oil, oil filter, and air filter on time.

The reasons for diesel engine oil combustion are as follows:1The oil ring is worn or the piston ring is damaged, and the piston ring is stuck in the ring groove by carbon deposit, which reduces the oil scraping effect of the piston ring, so that the oil on the cylinder wall runs into the combustion chamber at the top of the piston, resulting in oil burning; 2.

The continuous operation of diesel engines under high temperature and high load will cause wear of piston rings and cylinder liners, and pulling cylinders will cause oil combustion.

Burning engine oil is a common phenomenon, so there is no need to panic, but if the engine oil is burned, it must be solved as soon as possible. And if you want to solve the problem of burning engine oil, you must know what exactly causes burning engine oil.

In fact, the root cause of burning engine oil is that the domestic fuel quality and engine oil quality are too poor. The fuel is poor, everyone should still have a number in mind, but the oil is poor, a little bit I don't understand. In Europe, there must be 22% additives in engine oil, and the content of additives is as follows

Typical multigrade motor oils – 78% base oil, 10% viscosity improver, 3% detergent, 5% dispersant, 1% wear protection, 3% other components; The content of domestic oil additives does not exceed 15% at most, or even less. The poor quality of the engine oil not only does not clean away the dust inhaled into the air during the operation of the engine and the carbon deposits formed after combustion, but also the combination of gum and other impurities formed by self-oxidation will lead to the formation of more carbon deposits. These carbon deposits are deposited in the piston, which affects the outward elastic tension of the piston ring, causing the cylinder pressure to deteriorate. If it is deposited in the engine, it will cause poor lubrication, increased wear, increased fuel consumption, decreased power, and cause oil burning.

Burning engine oil is not a terminal disease, and burning engine oil is completely preventable, and the cost of prevention is also the lowest. The prevention method is also very simple, one is to regularly add Matti BE and Matti F to gasoline to keep the fuel system clean, inhibit carbon deposition, and improve combustion efficiency; The second is to add Marty M to the engine oil to improve the performance of the oil, such as cleaning, lubrication, protection, temperature control and other functions are more powerful, reduce engine dirt, avoid wear, so as to solve the problem of poor fuel and oil quality, and there is no need to worry about burning engine oil in the future. Whether to burn engine oil or not, the key is to learn to prevent it.

If the oil has already been burned, it must be solved as soon as possible. At present, there are two more popular ways to find land for overhaul, the quality of accessories, the level of technicians can be guaranteed, and the cost can be afforded, you can try, but after the overhaul, it will inevitably cause damage to the engine, which is common sense, the car is not broken, it is repaired!

The second is not to overhaul the solution, because the root cause of burning engine oil lies in the poor quality of oil and oil, resulting in excessive carbon deposits, which causes a series of problems such as piston ring stuck, cylinder wall wear, oil seal aging, etc., so as to burn engine oil, through high-quality cleaning and repair technology, such as the more popular German Marty, can solve these problems, do not overhaul can also solve the problem of burning engine oil, and solve the quality of gasoline and engine oil from the root, to ensure that there will be no more **.

The reasons for burning engine oil can be understood

1.Domestic oil products (including gasoline and engine oil) are prone to carbon deposits;

2.Carbon deposition causes the piston ring to jam and lose its oil scraping performance; The oil return hole is blocked, and the oil cannot return to the crankcase normally;

3.Wear between the cylinder wall and the piston, the gap is too large.

4.Corrosion and aging of valve seals and crankshaft seals lead to oil leakage.

Burning engine oil does not necessarily have to be overhauled, many car owners have not solved the problem after overhaul, and there are other problems in the car. You can go under the "no dismantling and repair to solve the problem of burning engine oil", and there is no need to dismantle and repair to solve the problem of burning engine oil, and there will be no harm to the car.

There are many reasons for the high water temperature of the engine or even "boiling", such as damage to the electronic components of the cooling system (thermostat, cooling fan), poor heat dissipation of the radiator, insufficient coolant, etc.

Pull over, but don't turn off the engine right away! Because the coolant temperature is already high and the cooling capacity has reached its limit, if the engine is turned off immediately, the boiling coolant will stop circulating (for most engines, the water pump is driven by the crankshaft).

Of course, if it is an electric water pump engine, it will be better), too high temperature is not cooled, the engine is also unbearable. If the engine is left idle for a while, the constant circulation of coolant can still reduce the impact of high temperatures on the engine.

Check for a lack of antifreeze that is causing high engine water temperatures. The circulation of the coolant, whether the circulation is not smooth. Secondly, you can also check that water temperature sensors, water pumps, thermostats, cooling fans, etc., may cause high water temperatures.

If you don't have a strong hands-on ability, you should go to the repair shop for an inspection.
