From the analysis of the principle of the automobile lubrication system, which parts should the oil pass through and return to the oil san?

1. When the piston is moving up and down, the oil channel is processed in the oil ring groove of the piston, and the oil scraped by the oil ring can flow back into the oil pan shell with gravity through this oil channel. On the other hand, oil can be spread to the cylinder wall to reduce the wear of the cylinder wall.

2. Principle: When the engine is running, the oil in the oil pan is coarsely filtered and sucked into by the oil pump. The oil pump pumps out the pressurized oil and enters the main oil channel after being filtered by the oil filter.Most of the oil in the main oil channel is used to lubricate the crankshaft main bearing and connecting rod bearing, and a small part enters the camshaft lubricating oil channel.

3. Generally speaking, the oil is in the oil pan at the beginning, and then sucked out by the engine-driven oil pump into the oil filter. After filtering out the impurities, it will enter the engine system to maintain the lubrication of components such as pistons, cylinders, cams and so on. After that, the oil will flow back to the bottom of the oil to precipitate and dissipate heat, and circulate in this way.

4. The oil finally flows back to the oil pan. The lubrication system of the Toyota ZR engine is shown in Figure 6-4. It drives the gear oil pump through the chain, and there is also a fuel injector on the cylinder block for cooling and lubricating the piston. The lubrication system of the Toyota 2NZ-FE engine directly drives the oil pump through the crankshaft.

5. After being filtered by the oil filter, it is transported to our main oil channel, crank connecting rod mechanism and tightening mechanism.

What parts does the lubrication system consist of

The lubrication system consists of three major parts: oil supply device: organic oil pump, oil channel, oil pipe, pressure limiting valve, etc., which can make the oil flow in the circulation system at a certain pressure and flow rate. . Filtering device: there are collector filters, coarse filters, fine filters, bypass valves (blockage indicators), which can remove various impurities in the oil.

The lubrication system is composed of three major parts: oil supply device, filtration device, instrument and signal device. Oil supply device: organic oil pump, oil channel, oil pipe, pressure limit valve, etc., can make the oil flow in the circulation system at a certain pressure and flow rate.

The lubrication system is mainly composed of oil span, filter collector (oil suction cup), oil suction pipe,It is composed of oil pump, pressure limit valve, safety valve, oil filter, main oil channel (body oil channel), oil pressure gauge (oil pressure indicator), branch oil channel, oil radiator, etc.

The lubrication system is composed of oil pump, oil filter, oil cooler, filter, etc. In addition, the lubrication system also includes oil pressure gauges, thermometers and oil pipelines.

What are the functions of turbine oil?

Turbine oil refers to flat oil, which is usually used to lubricate bearings. For low-pressure flat oil adjustment systems, turbine oil can be used to lubricate and regulate security, but for some units, such as fuel-resistant units, turbine oil is only used as lubricating oil, while security and regulating oil It is used to resist fuel.

The function is as follows: supply oil to each bearing of the unit in order to lubricate and cool the bearings. Supply stable and sufficient pressure oil to the regulating system and protection device, so that the regulating system and protection device can work normally. Supply lubricating oil to each transmission mechanism, and the function of the oil cooler is to cool the lubricating oil entering the bearings of the turbine.

The function of the oil system is to supply oil to each bearing of the unit, reduce the friction loss of the bearing contact surface and take away the heat generated by friction and the heat transmitted from the rotor.Supply stable and sufficient pressure oil to the speed regulation system and protection device to make it work normally. Supply lubricating oil to each transmission mechanism.

What parts does the lubrication system consist of? What is the function?

1. The function: The function of the lubrication system is to lubricate the surface of the relatively moving parts in the engine and reduce wear. The components are: cylinder head oil channel, camshaft, oil return hole, main oil channel, oil filter, collector filter, oil pump, oil sup shell, oil filling port, etc.

2. The function of the lubrication system is to deliver clean lubricating oil to each friction surface, which plays the role of lubrication, cooling, cleaning, sealing and rust prevention.

3. Components: lubrication pump, control module, distribution valve, safety valve, pipeline, etc.Depending on the needs of the system, add additional parts. The safety valve acts as an alarm indicator, such as the pipeline blockage. The bypass valve is responsible for transporting lubricating grease. The check valve is generally a one-way valve, which is conveyed in one direction to prevent grease from flowing back.

4. The main components of the engine lubrication system are as follows: oil pump: the function is to increase the oil pressure and ensure the continuous circulation of oil in the lubrication system. At present, there are two widely used oil pumps: external megging oil pumps and internal megging oil pumps. Among them, gear oil pump and rotary oil pump are two commonly used oil pump types.

The internal composition of the lubrication system, including high-definition illustration

The lubrication system is generally composed of oil pump, oil span, oil filter, oil radiator, various valves, sensors and oil pressure gauges, thermometers, etc. , as shown in Figure 3-66.

The automobile lubrication system consists of an oil span, an oil filter, an oil pump, an oil pipe and an oil channel processed into an engine housing. The functions of the lubrication system include lubrication, cooling, cleaning, sealing, rust prevention, etc., and can also provide pressure oil for the hydraulic valve gap regulator and variable valve timing device.

● The engine lubrication system is composed of oil pump, oil filter, oil cooler, collector filter and oil channel, etc., as shown in the figure. In order for the driver to keep abreast of the working conditions of the lubrication system at any time, some engines are also equipped with oil pressure gauges or other warning devices that indicate the oil pressure, and some are also equipped with oil thermometers.

The lubrication system is mainly composed of oil pan shell, oil pump, filtration device, pressure limiting valve, pressure gauge, oil gauge, oil channel and oil pipe, etc. (Figure 3-23).

The internal composition of the lubrication system 0 The function of the lubrication system The function of the lubrication system is to continuously supply the oil to the friction surface of the transmission parts to form an oil film between the friction surfaces, reduce the wear of the body, reduce friction loss, and reduce power consumption. It also has the effect of cooling, cleaning, sealing, prevention Effects such as rust.

Components of the lubrication system: The engine lubrication system consists of three major parts: oil supply device: organic oil pump, oil channel, oil pipe, pressure limiting valve, etc., which can make the oil flow in the circulation system at a certain pressure and flow rate.
