What is the function of the oil drain cup, and what is the function of the motorcycle oil cup

Purpose: The oil filter is located in the engine lubrication system. It is upstream of the oil pump, and downstream is the various parts of the engine that need to be lubricated.

Its function is to filter out harmful impurities in the oil from the oil pan, and supply the crankshaft, connecting rod, camshaft, supercharger, piston ring and other moving pairs with clean oil to lubricate, cool and clean, so as to prolong the life of these parts. Types: According to the structure, the oil filter is divided into replaceable, spin-on and centrifugal type; According to the arrangement in the system, it can be divided into full-flow type and shunt type.

The filter materials used in the oil filter include filter paper, felt, metal mesh, nonwovens, etc. Before the 80s, most of the oil filters used in national engines were replaceable. The filter of this structure is to put the filter element and other parts, such as springs, sealing rings, etc., into a metal shell, and connect and fix the shell filter element with a metal filter seat through a pull rod.

It has the advantage of low cost of use, and only needs to be serviced and replaced regularly. The disadvantage is that there are too many sealing points, and the maintenance and replacement of the filter element may miss parts, which is easy to cause loopholes, and it is troublesome to replace. What are the requirements of the oil filter for the filter paper The oil filter has higher requirements for the filter paper than the air filter, mainly because the temperature change of the oil varies from 0 to 300 degrees, and the concentration of the oil also changes accordingly under the drastic temperature change, which will affect the filtration flow of the oil.

The filter paper of a high-quality oil filter is able to filter out impurities and ensure sufficient flow under severe temperature changes.

The pistons and other components in the engine are all made of metal, can they rub against each other? Engine oil is all about giving them a lubricated environment. Fuel is used for combustion, and spark plugs are injected into the cylinder to produce energy, which is finally converted into torque to drive the wheels to roll.

There doesn't seem to be a vertical part on the motorcycle called "oil cup" to sell vertically, and there is an engine crankshaft.

The centrifugal oil filter at the right end is called "oil cup", if you are talking about that part, it is in the engine work, using the clutch force to throw out the heavier impurities in the oil, and deposited on the side of the oil filter, to avoid blocking the oil passage and wearing the engine. The gasoline filter on the motorcycle is generally called the gasoline cup, which is generally connected in series on the fuel pipe, or installed at the bottom of the fuel tank switch.

Engine oil has six major functions, namely: lubrication and friction reduction, cleaning and dispersion, cooling and cooling, sealing and leakage prevention, corrosion prevention and shock absorption and buffering.

1.Lubrication and friction reduction: A layer of oil film is formed on the surface of the two sliding parts, so that the parts will not be rubbed when running, so that the parts can run smoothly.

2.Clean and disperse: Good engine oil can wash the dirt on the surface of the parts through the flow of oil, adsorb some tiny metal debris in the engine, and then scrape off the oil pan by the piston oil ring.

3.Cooling and cooling: When the engine is running, high temperature is generated, and when the oil reaches the running part, it will absorb the heat, and then take the heat away to assist the parts to dissipate heat.

4.Leak-proof sealing: It refers to the formation of a sealing ring between the piston ring and the piston by means of oil film to prevent the exhaust gas from entering the crankcase after combustion.

5.Anti-rust and anti-corrosion, good engine oil can adhere to the surface of parts to prevent air, acidic substances and harmful gases from contact with parts, so that the parts are not corrupted by atmosphere and water, and protect the engine.

6.Shock absorption and buffering: When the pressure of the engine cylinder port becomes larger, suddenly the load on the piston, piston ring, connecting rod and crankshaft bearing is very large, and this load is transmitted and lubricated by the bearing, so that the shock load bears plays a role in buffering.

Answer: The functions of lubricating oil are: 1. Lubrication and wear reduction: when the car starts, there is relative friction between the piston and the cylinder, and the oil will form an oil film between the two friction surfaces, so as to achieve the purpose of reducing wear; 2. Cleaning:

Engine oil can bring dirty things such as carbon deposits, oil sludge, and metal wear particles on engine parts back to the oil pan to achieve the effect of cleaning; 3. Sealing and leakage-proof: the oil can also form an oil film between the parts with relative movement to improve their tightness, which is conducive to preventing air leakage or oil leakage; 4. Anti-rust and anti-corrosion: the oil will form an oil film on the surface of the parts through the movement of the parts, which can be adsorbed on the surface of the parts to prevent water, air and other contact with the surface of the parts and make the parts corrode and rust; 5. Cooling and cooling:

The oil carries some of the heat from the engine back to the oil tank and dissipates it into the air, helping the coolant cool the engine.

Hello, this is the role of lubricating oil.

What are the functions of lubricants for cars?

What is the role of lubricating oil? Star Awareness Project

Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts, mainly playing the functions of lubrication, cooling, rust prevention, cleaning, sealing and buffering.

The five main functions of motor oil:

1. Alleviate friction and high temperature: the oil film of sufficient thickness separates the surface of the relatively sliding parts, so as to achieve the purpose of reducing wear.

2. Sealing effect: The engine oil can form a sealing ring between the piston ring and the piston to reduce gas leakage and prevent external pollutants from entering.

3. Anti-rust effect: lubricating oil can absorb on the surface of parts to prevent contact between water, air, acidic substances and harmful gases and parts.

4. Buffering effect: when the pressure of the engine cylinder port rises sharply, the load on the piston, piston chips, connecting rod and crankshaft bearing is suddenly aggravated, and the load is transmitted and lubricated by the bearing, so that the impact load bears plays a buffering role.

5. Cleaning effect: good engine oil can bring carbide, sludge and wear metal particles on the engine parts back to the oil tank through circulation, and wash out the dirt generated on the working surface of the parts through the flow of lubricating oil.

1 All hello, the oil is not diluted, gasoline lubrication, heat dissipation, cleaning, buffering, anti-rust sealing.

That's pretty much it.

Hello, the engine oil cannot be diluted, the function is to lubricate, heat dissipation, cleaning, buffering, rust prevention, sealing, and cannot be diluted.

There are three kinds, 1 is lubrication and 2 is cleaning. 3. Cool down.

Hello, the oil on the outside of the oil cap may be caused by the problem of the oil cap itself, there is a glue ring inside the oil cap, and the aging of the rubber ring may leak oil. Hope it helps you!

The oil filters are made of paper, and the shell is made of iron.

1. It is a filter element with paper and iron separated, and the paper filter element only needs to be changed, and the iron shell can be used for a long time. It is easy to repair and replace, and the cost is low. The filtration accuracy is relatively low.

2. Paper and iron are the overall filter element, sealed, the filtration effect is good, the cost is higher, and the overall filter element will replace the paper filter element.

After ruling out the possibility of using inferior engine oil, the main reason for the above phenomenon is generally caused by the high-temperature mixture in the combustion chamber channeling into the crankcase and contacting the lubricating oil, and at the same time carrying a large amount of soot, in which case the lubricating oil is subjected to high temperatures far beyond normal use conditions. The main reasons for the occurrence of blow-by are as follows:

1.If the gap between the piston, piston ring group and the cylinder wall is too large (it may be caused by wear, ring matching, ring jamming, foreign body intrusion, etc.), the high-temperature and high-pressure mixture will enter the crankcase through this gap during the power stroke.

2.Combustible gases enter the crankcase through excessive clearance between the valve and the valve guide, or through the excessive clearance at the failed valve seal.

If the car does not change the oil in time for a long time, with the wear and tear of the engine and the formation of deposits, as well as the reduction of oil due to its own consumption, the combined effect will lead to an increase in the viscosity of the oil, and in many cases even coking substances will be found.

The phenomenon of engine oil becoming like asphalt" mostly occurs in some under-maintained operational diesel vehicles. Lubrication failure due to the loss of fluidity of the oil, the light case burns the shaft and the heavy engine is scrapped. In fact, the key to preventing the occurrence of the above problems lies in choosing oil and maintaining the engine regularly (such as regularly checking the engine, changing the oil, replacing the three filters, etc.).
