Why do gasoline engines add oil?

Reason 1: During the operation of the engine, a small amount of iron shavings will be produced and suspended in the engine oil.In addition, the carbon accumulation and sulfides formed by the incomplete combustion of gasoline will also enter the oil sap from the cylinder wall, mixing with the oil to blacken the oil and accelerate the deterioration of the oil.

High-quality engine oil is a finished product with a variety of engine protection functions. The formula already contains a variety of additives, including anti-wear agents, and the engine oil pays the most attention to the balance of the formula to ensure the full play of various properties.

Auxiliary cooling: Due to its low specific calorific value, the oil itself does not have a cooling effect inside the engine.

The oil will be consumed naturally with the operation of the engine, and the phenomenon of oil leakage or burning oil in the engine will reduce the amount of oil and affect the lubrication of the engine. This requires regularly pulling out the oil scale to check the oil level, and adding it to the safety line position if it is lacking.

Lubrication, reducing wear Lubricating oil, the first task is of course lubrication.During the operation of the engine, the surface of various metal parts will produce high-speed friction. The function of the oil is to form an oil film between the parts through flow, reduce the frictional resistance, and achieve the effect of reducing wear, thus prolonging the life of the engine.

The car oil lamp and the engine light are on together, and the car can't start. What's going on?

1. The reasons why the car oil light and the engine light are: insufficient oil, so that the engine oil The amount of oil pumped in the pump is reduced or the oil cannot be pumped due to the inlet of air, resulting in a decrease in the oil pressure; if the engine temperature is too high, it is easy to make the oil thin, and a large amount of oil is lost from the gap, resulting in a decrease in oil pressure.

2. Engine failure, car oil lampWhen the engine light is on, it means that the vehicle engine needs to be maintained/maintenance. Generally, the engine should be checked in time at this time/find the nearest vehicle repair shop for maintenance/maintenance, because the engine is the heart of the vehicle, and it should be maintained regularly in time to avoid the vehicle from breaking down on the road during use.

3. If the car is faulty and can't be ignited, it can't be said that it's because the fault light is on. The CS75 engine fault light is always on, which may be due to the poor combustion state of the engine and the accumulation of carbon.

4. Oil indicator light: If the light suddenly lights up while the vehicle is driving, it does not mean that the engine of the vehicle is faulty. More reasons are due to the lack of oil and the low pressure of engine oil.

5. The engine oil is insufficient, and the engine needs to be lubricated by the engine oil, so the fault lights in both places are on.

Is there a direct relationship between the power of the car engine and the quality of the changed oil?

The quality of the oil has an impact on the engine power. Good oil quality will increase lubrication, reduce wear, reduce engine temperature, so that the engine power output is more stable; poor qualityThe engine oil will aggravate the wear of the engine, causing the engine to pull the cylinder, so that the engine power cannot be output normally.

Influential. Oil plays an important role in lubricating, cooling and cleaning the engine. High-quality engine oil can provide better lubrication performance, reduce internal friction and wear of the engine, so as to maintain the efficient operation of the engine. At the same time, good cooling performance can effectively reduce the engine temperature and prevent damage caused by overheating.

Oil has an impact on the power of the car. Good oil has high lubrication efficiency, which makes the friction between parts smaller, thus strengthening the power of the car and prolonging the service life of the vehicle. Engine oil mainly plays the role of lubrication and wear reduction, auxiliary cooling and cooling, sealing and leakage prevention, rust and anti-corrosion, shock absorption and cushioning and so on.

Insufficient engine power is also closely related to engine oil.First of all, the quality of the oil affects the performance and power of the engine. Therefore, we must choose the right oil and replace it on time. Secondly, the engine is the heart of the car. There are many metal surfaces in the engine that rub against each other, and the working temperature can reach 400℃-600℃.

What is the impact of bad oil on the engine

The quality of engine oil will have a certain impact on the engine. If good engine oil is used, the noise of the engine will be lower and the wear will be lower. If poor-quality engine oil is used, the engine will be more noisy when working, which will aggravate engine wear. Engine oil lubrication, cleaning, sealing and heat dissipation.

The effects of poor oil on the engine are as follows: 1.The lubrication effect does not meet the standard, resulting in the intensification of the wear of various bearings and moving parts of the engine, reducing the service life of the engine; the excessive temperature of the engine affects the operation of many precision electronic devices; the useful work of the engine is reduced, the additional work increases, and the fuel consumption increases.

The lack of engine oil will cause poor heating of the engine, abnormal shaking of the car, high water temperature, sound of the valve, and even serious consequences such as pulling the cylinder wall or bursting the cylinder. Burning engine oil is basically caused by piston ring jamming. As long as there is no serious strain on the tank wall, there is no need for overhaul.

The first thing is that the lubrication effect is not qualified, resulting in the damage and aggravation of various bearings and moving components of the engine, which greatly reduces the service life of the engine; and the insight will cause excessive engine temperature, which will affect the operation of many precision electronic equipment;To the extent that it affects the fuel consumption, that's for sure.

If the oil is not good, its lubrication effect will not meet the standard, and it cannot transform the dry friction between metals into liquid friction between oil layers, resulting in damage to engine parts and affecting the service life of the engine.

The longer the time, the worse it will be for the engine. If it is serious, it will cause the cylinder to be pulled because of the hard carbon accumulation. Finally, the engine has to be overhauled. If the long-term combustion is not good will also lead to premature aging of the exhaust valve and oil seal, cracks, and it will also affect the solution of burning the engine oil. As long as the car does not pull the cylinder, but it encounters a piston ring jam. The problem of burning engine oil caused by.
