During the coordinated operation of numerous automotive components, lubrication is the key to ensuring their efficient and stable operation. Silicone oil, with its excellent performance, provides high - quality lubrication solutions for various automotive components, playing a unique role in different critical parts.

1. Engine Lubrication

• Silicone - based Lubricating Oil：Inside the engine, it is a high - temperature, high - pressure environment where components move relative to each other very frequently. The friction between components such as the piston and the cylinder wall, and the crankshaft and bearings is extremely large. To reduce the wear of these components and improve the engine's efficiency, silicone - based lubricating oil has emerged. When manufacturing silicone - based lubricating oil, the proportion of silicone oil and various additives needs to be precisely adjusted. Additives usually include antioxidants, anti - wear agents, detergents, and dispersants, which work in conjunction with silicone oil to comprehensively enhance the performance of the lubricating oil.
• Lubrication Mechanism：When the engine starts, the silicone - based lubricating oil quickly forms a firm and uniform oil film on the surfaces of various moving components. This oil film is like a smooth "track" laid between the components, greatly reducing the coefficient of friction. In a high - temperature environment, the high boiling point and low volatility of silicone oil ensure that the lubricating oil does not vaporize or evaporate easily, thus continuously maintaining a good lubricating state. Compared with traditional mineral oils, silicone oil has better antioxidant properties at high temperatures, is less likely to oxidize into gums and carbon deposits, avoiding wear and blockage of internal engine components caused by these impurities, and effectively extending the engine's service life.

2. Transmission Lubrication

• Hydraulic Transmission Fluid and Gear Lubricating Oil：In the automotive transmission, whether it is a manual transmission or an automatic transmission, good lubrication is required to ensure smooth gear shifting and the normal operation of components. For automatic transmissions, silicone - based hydraulic transmission fluid not only undertakes the important task of power transmission but also provides lubrication and cooling for the gears, shafts, clutches, and other components inside the transmission. This hydraulic transmission fluid is a mixture of silicone oil and specific additives, and the additives can enhance its anti - wear, anti - foaming, and low - temperature fluidity.
• Working Process：When the automatic transmission is operating, the hydraulic transmission fluid circulates under the action of the pump. When the engine's power is transmitted to the transmission through the torque converter, the hydraulic transmission fluid plays a role in transmitting torque, enabling flexible connection between the engine and the transmission. At the same time, during the oil circulation process, it continuously flushes the surfaces of various components, taking away the heat generated by friction and forming a lubricating film on the component surfaces to reduce wear. In a manual transmission, silicone - based gear lubricating oil is mainly used to lubricate the gears and bearings. It can effectively buffer the impact force when the gears mesh, reduce noise, and ensure smooth gear transmission.
