What accessories do you need to change when the Fox engine oil burns badly?

The reasons for burning oil are as follows:

1. Bad valve seal: The valve is designed to prevent oil from leaking into the combustion chamber. However, with the increase of service life, it will wear and age, make the valve sealing worse, and make the oil easily enter the combustion chamber.

2. The piston clearance becomes larger: after long-term operation, there will be carbon deposition on the piston and a certain degree of wear and tear. With the passage of time, the piston clearance becomes larger, and the oil enters the combustion chamber more easily. This is also often said, the vehicle has been used for a long time, so it is necessary to replace the oil with higher viscosity.

3. The viscosity of engine oil is too small: if the viscosity of engine oil used is too small, the phenomenon of burning engine oil will also occur. When the viscosity of engine oil is too small, it has good fluidity and is easy to escape into the cylinder and then participate in combustion.

4. Too much oil: If the oil pressure is too high, part of the oil will be pressed into the cylinder, causing the oil to burn. The solution of burning engine oil in automobile engine is to repair the engine, clean up the carbon deposit in the engine and replace the damaged parts. If the situation is serious, the engine needs overhaul.

Serious classification of engine oil combustion

Within 2000, one liter is heavy engine oil, 2000-4000 is medium engine oil and 4000-5000 is light engine oil. According to the national standard GB/T 19055-2003, the consumption ratio of engine oil at rated speed and full load shall not exceed 0.3%, that is, every 5000 km 1- 1.5L lubricating oil is normal loss.

How did the piston ring get stuck?

In fact, the principle of piston ring sticking should start from the oil circuit, and the reason for sticking is the oil circuit. The temperature of the oil bearing is 1 10℃, and the high temperature caused by the long-term uncleanness of the oil circuit keeps the oil at 120℃ or higher for a long time, so that the oil will be exhausted ahead of time, and the small holes in the oil ring will dry, crust and stick for a long time. One cylinder stuck is 5000 kilometers per liter of oil, then the working conditions of other cylinders began to be bad, and soon all four cylinders got stuck, becoming 1000 kilometers or even hundreds of kilometers per liter of oil. Therefore, to solve the problem, we must start with the root oil circuit, which is the way to get rid of the root.

First, make sure there is no need for overhaul. The waste gas valve should be checked, but the oil pollution of the hose is definitely not the criterion for judgment. Need to check whether the lower cylinder wall is seriously worn. If there is no serious wear and tear, there is no need for overhaul. Now the demolition-free technology is very mature and gradually accepted by the majority of car owners. In particular, PNF nondestructive repair technology has completely got rid of the technical shackles of operating in auto repair shops. Without disassembling a screw, the owner can operate it by himself, and the effect of repairing and releasing the burning oil in the piston ring during driving is remarkable.
