The engine of the car is separately lubricated from the transmission and the clutch. The temperature of the oil in the crankcase is about 75-90 ° C. The motorcycle engine includes the wet multi-plate clutch, the high speed and transmission gear, the shifting mechanism, and the piston and cylinder. The moving parts such as the intake and exhaust valves are all in the same structure, sharing the oil in the same volume. Moreover, the friction of the clutch and the shifting gear will generate a lot of heat, and the temperature of the oil in the crankcase can reach 80-120 °C.
2, the difference in cooling effect
The engine oil capacity of a car engine is about 5-7L, while the motor oil of a motorcycle engine is only about 1L. Only when the engine oil is fully flowing can the heat dissipation performance be exerted.
The amount of oil has a great influence on the heat dissipation performance. In addition, most motorcycles are generally air-cooled, and the cooling effect is much worse than that of the car's water tank. Even the water cooler is poor in heat dissipation because its water capacity is smaller than that of the car. This will inevitably cause the engine oil temperature of the motorcycle engine to be much higher than the temperature of the engine oil.
3. Differences in oil filtration
The car's oil filter is quite complete, with a strainer and a fine filter, the filter effect is excellent, and the motorcycle is very different. In order to reduce the weight and volume of the motorcycle, the oil filter is relatively simple in design, and it is not surprising that the filtration effect is poor.
4, the difference in power per liter
The displacement power of a car is generally 60-80Kw/L, while that of a motorcycle is 100-120Kw/L, which is about 1.5 times that of a car, and the volume power is twice that of a car. The calibration speed of an automobile engine is usually 3000-5000r/min, while the calibration speed of a motorcycle engine is about 8000-11000r/min, which is 50% to 120% higher than that of a car. At maximum power output, the speed of the motorcycle engine is between 10,000 and 15,000 r/min, while that of the car is between 4000 and 5000 r/min and the maximum is no more than 6000 r/min.
5, the strength of the reinforcement is different
Due to differences in driving conditions and various technical requirements, the strength of the motorcycle engine is usually 3-4 times higher than that of the car. The body of the motorcycle is light and often travels at the maximum power or maximum torque output. The engine temperature is not only high but also wears out. It can be seen that the working environment of motorcycles is much more demanding than cars.
6, oil performance difference
Compared with automobile oil, motorcycle engine oil pays more attention to oil high temperature resistance, excellent thermal oxidation stability and low temperature startability. It can effectively remove deposits on engine parts, prevent sludge generation and protect engine under severe conditions. It is not damaged, reduces the consumption of oil, and provides better protection for the engine when the road and weather conditions are bad, thus prolonging the service life of the engine. Motorcycle oil should ensure stable performance under high temperature conditions, ensure a certain oil film thickness, ensure that all moving friction parts can be reliably lubricated, and play motorcycle high power. High torque and instant acceleration.

Tandem Cold Rolling Mill Line means continuously rolling metal strip by going through two rolling mills, three rolling mills, four mills, five mills, even 6 mills to output the required gauge once rolling.
Tandem rolling mill gives high production, thousands of tons cold rolled coils per year, and higher metal strip utilization percentage. Big scale cold rolling mill plants must have tandem mill to meet market demand.
To know what model, capacity of tandem cold rolling mill, we need cusotmer to tell his steel strip max width, input and output thickness, yearly production.
We can do turnkey project of cold rolling mill complex, welcome you to consult!
