What are the precautions for oil-cooled engines?

First: First of all, pay attention to whether the interface and elbow are leaking oil, and whether the sealing work is done well. Second: The use of engine oil will be more than before installing the oil cooling, because the oil cooling needs to store a certain amount of oil. When changing the oil, the oil in the oil cooling must be cleaned up.

Mineral oil and fully synthetic oil cannot be mixed. From a technical point of view, it is no problem to mix different types of engine oil. However, it should be noted that while mixing oil, you are also mixing the additives in them. It is not necessarily a good thing to mix the additives in different oils.

The oil cooling area is selected reasonably, the installation position is also reasonable, and the installation method must be correct.The specific oil cooling effect varies according to each machine, and the oil cooling measurement should be tested under the guidance of professionals.

For this reason, the following are a few issues that need to be paid attention to when using the engine in winter: add antifreeze. If the engine can start smoothly, it is best to use antifreeze as coolant. The quality of the selected antifreeze must be qualified, especially the pH and stability of the antifreeze must meet the requirements, otherwise it will corrode the waterway and water seal, causing water leakage and other faults.

Is it okay to add oil cooling to the water-cooled engine?

1. It can't be changed. The cylinder head, cylinder block, engine whole box and many other parts of the air-cooled engine and water-cooled engine are completely different. The only way to change is to change the engine assembly, but it can be modified.Oil cooling, which is relatively easy, but it is difficult to say how much stronger the effect is than the current air cooling, and the effect is not very big.

2. When many drivers do maintenance in 4S stores, they will be persuaded by the staff to install oil cooling on the water-cooled engine. In fact, this is not necessary. Most cars on the market use three types of coolant, including ethylene glycol antifreeze, anhydrous antifreeze and cooling oil.

3. Water cooling: The water-cooled spindle is easy to rust, and the water source needs to be replaced frequently. The refrigeration method of the water cooler is only fan refrigeration, fan heat dissipation, and there is no refrigeration system itself.

4. Is LZ air-cooled to oil-cooled or water-cooled to oil-cooled? There is no need to change air cooling to oil cooling. Air cooling has met the requirements of heat dissipation. Water cooling to oil cooling is not good. The specific heat capacity of water and the specific heat capacity of oil are different. The temperature of oil generally rises faster, and the requirements for heat dissipation device are relatively high.

5. Hello, it's okay, but it's too expensive. Oil-cooled maintenance-free for life. [ If there is a problem with the car, ask the car master. 4S store professional technician, 10 minutes to solve.

Which is better, water-cooled motor or oil-cooled motor

Water-cooled motor is better. Smell and cost. In terms of cost. Large electric spindle water cooling canBy selecting high-quality coolants, such as special coolants for automobiles, it reduces the possibility of corrosion, and also increases the cooling effect to ensure that the spindle is working at the appropriate temperature. The discharge and treatment of wastewater are more environmentally friendly than oil products.

Water cooling is good. Nowadays, many models on the market adopt water-cooled engine cooling. Water cooling is to cool the engine with water. The purpose of cooling the engine through various tools. Therefore, its cooling method. It's relatively simple. The cooling effect is also relatively good, although the effect is relatively good.

In theory, oil cooling is better. Cooling time: Because the cooling speed of oil is slower than that of water, the cooling time of oil cooling is longer than that of water cooling. Hardness of quenching: high water cooling, low oil cooling. Chen quenching deformation: large water cooling, small oil cooling. The tendency of quenching cracking: large water cooling and small oil cooling.The depth of the quenching layer: deep water cooling, shallow oil cooling.

"The following is my personal opinion: Generally speaking, water cooling is better, the oil-cooled engine is easy to overheat, and the radiator is relatively large: the specific capacity of oil is too small, and water has the largest specific heat capacity in nature, that is, the water temperature rises by 1 degree and absorbs more heat than oil.
