How do I change my diesel oil? How long does it take to change the oil for a new diesel engine?

1Put the car on a flat road so that the oil can be completely drained. 2. Remove the oil drain nut on the oil pan first, and use something below to prevent the oil from leaking into the ground. 3. After the oil is discharged, don't forget to put the oil drain nut on, and don't leak the oil while adding the oil.

Refuel the new engine oil from the oil filler, generally the oil is about 4L between the max and min lines on the oil dipstick. 4. After the oil is filled, the oil filter is also replaced, which is cheap. This must be changed when changing the oil.

5 Generally, the vehicle needs to change the oil and oil filter once at 5w 8w km. Satisfied.

1. Put the old oil, if the oil circuit is dirty, it is recommended to use the new oil to idle the cycle for flushing. When changing the oil, it is necessary to replace the filter together to ensure the cleanliness of the entire oil circuit 2, ensure the cleanliness of the auxiliary refueling equipment, and avoid the entry of external pollutants 3. Control the appropriate amount of refueling should not be too much or too little, after oil injection, it is necessary to idle for 2 3 minutes, and check whether the oil level meets the requirements again for about 10 minutes to be turned off 4. Finally, the oil injection port needs to be tightly covered to prevent external pollutants from entering.

There is a screw at the bottom, you loosen it, take something to hold the oil, drain the oil, you can use Jiao Hand Jiao if you are afraid of not drying, install the screw after the oil is finished, the oil hole is on it, and the oil is OK when you pour the oil to the dipstick position.

Generally speaking, the oil needs to be changed every 5,000 kilometers, and if you drive on a dusty road for a long time, the replacement period should be shortened by about 3,000-4,000 kilometers. When changing the oil, change the oil compartment at the same time.

Diesel vehicles generally have difficulty starting in cold weather, one of the main reasons is that the oil concentration does not meet the regulations and does not change the engine oil for a long time, so it is more important to pay attention to the engine oil when the weather is cold.

If it is a normal vehicle, then the oil needs to be changed every 5000 kilometers, but if it is a new car, the oil should be changed for about 2000 kilometers for the first time, but generally under normal circumstances, the air filter and gasoline filter need to be replaced every 10000 kilometers, in order to ensure the safety performance of the car itself. Automobile diesel is a special fuel for diesel engine vehicles, and has good power performance, high power, durability and reliability, and excellent cleanliness. As a result, the demand for domestic automotive diesel has been rising rapidly.

The main difference between a diesel engine and a gasoline engine is the way of ignition.

The run-in time of the new engine cylinder is about 10 hours or even less, so that the engine oil can be not channeled and the oil is not burned. Do not put into heavy load operation for 60 hours. The specific run-in time can be carried out according to the requirements of the manufacturing plant.

When the engine is running-in, the speed should not be too high, generally 1000-1400r min, and the water temperature should be kept at 75-80 degrees. Take a close look at the pads everywhere. Oil seals.

Whether there is oil leakage in the water seal and joint. Leaking. Creepage.

air leakage; Check the ammeter. Oil pressure gauge. whether the water temperature gauge reading is normal; whether the operation is uniform and stable; Check all parts of the engine for abnormal noises.

As for the gearbox, it should be run in with the engine, and the load of the run-in should be from small to large, and gradually increase. Start with a low rpm and gradually increase the rpm in stages.

Hope it helps.

Mainly look at the category of diesel engine selection:

CF-4 level source balance oil change interval is 8000-12000 km.

The CH-4 oil change interval is between 15,000 and 20,000 litres.

The CI-4 oil change interval is around 25,000 metric miles.

Correct way to change the oil:

2. Drain oil when the oil is in a hot state;

3. Place the oil drum under the oil drain plug, loosen the oil drain plug at the bottom of the diesel engine, and let the waste oil flow into the barrel, ** waste engine oil;

4. Clean the oil drain pool and oil plug with diesel oil, and wash off metal chips or other debris;

5. After installing the clean oil drain plug, add fresh and clean engine oil;

Expand the information Xiang answer code:Engine oil also cools and cleans the engine. Engine oil consists of base oils and additives.

Base oils are mainly refined mineral oils, synthetic oils, or blends of refined mineral oils and synthetic oils. Additives include antioxidants, viscosity index improvers, pour point depressants, anti-corrosion and antirust agents, cleaning and dispersing agents, friction modifiers, anti-wear agents, etc.

Engine oil is further divided into gasoline engine oil and diesel engine oil, which are used in gasoline engines and diesel engines respectively. In order to facilitate car users, in recent years, general oil, that is, the lubricant used for gasoline and diesel engines, has been introduced.

Disassemble the oil pump and replace the oil pump assembly.

When the diesel engine is working, the oil pump will be pressed to the friction surface of the parts and form an oil film, so that the parts that rub against each other will not be in direct contact, so as to reduce the friction loss. The oil pump should pay attention to the oil pressure at any time in use, when the oil pressure is too low, it should be stopped immediately for inspection and maintenance, the oil pressure is too high will also destroy the oil film and aggravate the wear, the user should also find out the cause and eliminate it in time.

First of all, you need to drain all the oil, disassemble the engine oil pan, and remove the oil pump assembly to replace it.

The oil pump is the main component in the lubrication system of the diesel engine, and its function is to increase the oil to a certain pressure and then force it to the moving surface of each part of the engine. The structure of the oil pump can be divided into two categories: gear type and rotor type. Gear oil pumps are divided into internal gear type and external gear type, and the latter is generally called gear oil pump.

The oil pump for diesel engines is either built-in (in the oil pan) and external (installed on the outside and visible). The built-in oil pan needs to be disassembled, and the external one can be directly disassembled and replaced. Pay attention to the bearing clearance and transmission gear when replacing, there is no timing, it is very simple, the gear pump should mainly check the axial clearance.

It mainly depends on where the oil pump is, some are in the gear room, and some are in the oil pan.

Open the oil pan and the oil pump can be replaced. Zaoyang Yongxin forklift.

Correct way to change the oil:

2. Drain oil when the oil is in a hot state;

3. Place the oil drum under the oil drain plug, loosen the oil drain plug at the bottom of the diesel engine, and let the waste oil flow into the barrel, ** waste engine oil;

4. Clean the oil drain pool and oil plug with diesel oil, and wash off metal chips or other debris;

5. After installing the clean oil drain plug, add fresh and clean engine oil;

1. Place the generator set in a plane and start the engine for a few minutes to increase its oil temperature and then stop the engine.

2. Remove the oil injection bolt (i.e. the oil ruler).

3. Place an oil basin under the engine, remove the oil drain screw, and the oil can be discharged from the crankshaft oil tank.

4. Check the oil drain screws, sealing rings and rubber rings, if damaged, please replace them immediately.

5. Reinstall the oil drain screws and tighten them.

6. Add the lower oil to the upper position of the oil scale grid.

The role of oil in diesel generator sets:

1. Lubrication: There is a rapid relative sliding between the piston and the cylinder, between the spindle and the bearing, and an oil film needs to be established between the two sliding surfaces to prevent the parts from wearing too quickly. An oil film of sufficient thickness separates the surface of the relatively sliding part to reduce wear.

2. Auxiliary cooling and cooling: the specific calorific value of the engine oil is low, and it does not have a cooling effect inside the engine. However, due to the heat generated by fuel combustion in the engine, when the engine is working, the oil can bring the heat back to the oil tank and then dissipate it into the air to help the water tank cool the engine, and the real cooling effect is the water (or antifreeze liquid) outside the engine case.

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

4. Sealing and leak-proof: The oil can form a sealing ring between the piston ring and the piston to reduce gas leakage and prevent external pollutants from entering.

5. Anti-rust and anti-corrosion: lubricating oil can be absorbed on the surface of parts to prevent water, air, acidic substances and harmful gases from contacting parts.

6. Shock absorption and buffering: 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.

7.Anti-wear: adding lubricant to the friction surface can reduce the friction coefficient, thereby reducing friction resistance, saving energy consumption and reducing wear: lubricants can reduce the friction caused by abrasive wear, surface fatigue and adhesive wear between the friction surfaces.

Generally, diesel engines are equipped with organic oil filters, and the oil filter element should be replaced at the same time as the oil is changed. Changing the oil is very simple, as long as the oil drain screw of the oil pan of the diesel engine is unscrewed, you can drain the oil, after the release, add new oil, pay attention to the scale of the oil dipstick, and add it to the highest position.

Change the oil and drain the oil when the engine is warmed up. The normal replacement time for the oil and oil filter is every 250 hours, and the oil and oil filter change interval is 100 hours when used in harsh conditions. Attention should be paid to safety when replacing, hot oil can cause burns.

Diesel engines have special oils, and there are also classifications. It is generally fully synthetic.

Fully synthetic diesel engine oil is generally 10,000 kilometers or 1 year to replace a state.

The API grades of diesel engine oil are CD, CE, CF-4, CG-4, CH-4, and CI-4. C is the meaning of diesel engine, followed by the word pure mother, the higher the API level.

Summary. 1. First of all, put the car on a flat road, so that the engine oil can be completely discharged; 2. If you want to put oil, you can remove the oil drain nut on the oil pan, and it is best to use something to connect it below, so as not to leak the oil into the ground; 3. After the oil is discharged, don't forget to install the oil drain nut to prevent oil leakage while adding oil, and then add new oil from the oil filler port.

4. Generally, the engine oil is about 4L, and it can be added between the max and min lines on the oil dipstick. This diesel fuel does not need to be cleaned to remove the socks, so directly open the oil port, put the oil clean, and then add new oil.

In recent years, with the continuous development of China's industrialization, the application range of diesel engines is becoming more and more extensive. Especially in the application of agriculture, diesel engine is one of the indispensable agricultural machinery in agriculture, but it is the main force of agricultural development.
