Internal Combustion Engine & Oil Pumps In High Performance Engine
An oil pump in an internal combustion engine circulates the engine oil under pressure to the engine's rotating bearings, sliding pistons, and camshafts. This lubricates the bearings, allows the use of large-capacity fluid bearings, and also helps cool the engine.
In addition to the main purpose of lubrication, pressurized oil is also increasingly used as hydraulic oil to power small actuators. One of the first significant uses of this approach was hydraulic lifters for camshaft and valve actuation. Applications that have become more common lately include tensioners for timing belts or transmissions for variable valve timing systems.
Use electric oil pumps again to improve reliability. Some "turbine timer" electric auxiliary oil pumps are sometimes installed on turbocharged engines. These are the second oil pumps that continue to run after the engine has stopped, providing cooling oil to the turbocharger's thermal bearings for several minutes while cooling.
Oil pumps in high-performance engines
Not all engines have the same fueling requirements. For example, high-performance engines put more pressure on lubrication systems. In this case, the lubrication system must be particularly robust to prevent engine damage. Most automotive engines on the road today do not exceed 5,000–6,000 rpm, but this is not always the case for high-performance engines, as high-performance engines may reach 8000-9000 rpm. In this type of engine, the oil must circulate fast enough, otherwise air may be trapped in the oil. In addition, in order to release power, the engines in some high-performance applications are running lighter oil, which requires less power to run the oil pump. Today, the common oil weight in engines is usually 5W-30 or 10W-30, while high-performance engines may use 0W-20 oil, which has a lower viscosity.
Zhejiang Yongling Hydraulic Machinery Co., Ltd. specializes in the production and supply of oil pump products in China. The Oil Pumps works by circulating the oil under pressure to the engine's rotating bearings, sliding pistons, and camshafts. Large-capacity fluid bearings can be used to help cool the engine.
