BMW Mini n12 hairThe method of replacing the generator belt

1. The method is as follows: Before replacing the generator belt, first unscrew the support nut of the development motor with a wrench. Loosen the track screw and push the generator to the engine. After replacing the belt, push the generator back. After using the pry bar to tighten the generator, tighten the track screw first, and then tighten the support frame nut, and the replacement is completed.

2. Loosen the motor fixing screw and the belt tightness adjustment screw. Push the generator against the engine to make the distance between the pulleys the shortest, and then straighten the belt sleeve. Adjust the tightness of the belt to the appropriate level, and tighten the engine fixing screw and adjustment screw.

3. The method is as follows: align the crankshaft according to the mark on the crankshaft timing pulley, and the stop position on the 1 cylinder piston is generally required. AtInstall the mark on the camshaft timing pulley, align the camshaft, and aim at the two camshaft positions respectively. In this way, the belt can be wound and installed.

4. First, turn off the BMW b48 generator, open the hood, and find the generator belt in front of the engine. Secondly, press the belt between the pulleys to check its degree of relaxation. Finally, peel off the generator belt from the pulley and remove the generator belt.

5. The installation method of the BMW x1 belt is as follows. First, open the hood. After supporting it, use the tool to disassemble the air intake decorative panel at the front of the car. Next, twist the tensioning wheel. After the tensioning wheel is loosened, the belt will loosen, and the owner can remove the old belt.

What kind of oil should be added to the n12 engine

1. MINI PACEMAN is BMW's small-displacement horizontal front-wheel drive platform engine N16 or N12, which uses lubricating oil that meets the BMW oil specification Longlife004 specifications, and the common one is 5W30.

2. Engine type The engines on the market are divided into naturally aspirated engines and turbocharged engines. Mineral oil or semi-synthetic oil can be used for naturally aspirated engines, and fully synthetic oil can be used if conditions permit.Because the temperature of the naturally aspirated engine is not so high, and the requirements for oil are not so high.

3. Semi-synthetic oil: The replacement cycle of semi-synthetic oil is generally about 8000-10000 kilometers, and the price and performance are moderate. Mineral oil: This type of oil generally needs to be replaced at about 5,000 kilometers. For diesel engines, CB-CD-grade diesel engine oil should be selected according to the mechanical load.

4. BMW longlife-01Fe, BMW longlife-04; diesel engine: BMW longlife-04) For details, please refer to other optional oil types of BMW. If you can't buy the licensed oil, you can follow the gasoline engine: BMW longlife-98, ACEAa3/B4;Diesel engine: The specification of ACEAC3 is to supplement 1 liter of oil.

5. Oil is an engine lubricant, which plays an important role in the engine, such as lubrication, cleaning, cooling, sealing, wear reduction, shock absorption and buffering, and rust prevention and corrosion prevention. At present, there are three types of engine oil on the market: ordinary mineral oil, semi-synthetic oil and fully synthetic oil.

6. At present, almost all engine oils are multi-stage oils common to all seasons. The oil barrel marked with W (winter) is multi-stage oil. If there are no special circumstances, there is no need to deliberately change the oil even in winter.

Wuling Rongguang N12 engine oil volume

1. Normal. According to the official website of Wuling Rongguang, the oil capacity of Wuling Rongguang is between 5L and 4L.So it's normal to add 5 liters. Wuling Glory is a model launched by SAIC GM Wuling in 2008. In 2013, SAIC General Motors Wuling launched the modified Wuling Glory S on the basis of Wuling Glory.

2. Wuling Rongguang 2L displacement needs to add 5 liters of oil. The following is the method to check the amount of oil and the replacement cycle of the oil: How to check the amount of oil: When checking, stop the car, tighten the handbrake, and start the engine. When the normal working temperature is reached, turn off the engine and wait for a few minutes to let the oil flow back to the oil sump.

3. In actual use, there will be certain differences in the size of the maintenance tools, methods and displacements (as shown in the figure below, different models, different cylinder diameters, different displacements, etc.), which are roughly between 5~5 (L). The specifics shall be subject to the description standards of the relevant chapters of the "User Manual" accompanying the car.

4. Hello, according to your description, the amount of oil of Wuling Rongguang's new card is about four liters. I hope you can adopt it. Thank you.

5. The poster, the maintenance oil consumption is about 5 liters. The manufacturer uses SJ-grade 5W-40 oil, and the use of 5W-40 oil higher than SJ-grade is matching. If synthetic oil is used, the maintenance cycle can be extended depending on the situation.

The BMW Mini N12 engine idles at great jitter

The engine has serious carbonisation. The most common cause of idling jitter is excessive carbonisation of the throttle valve or fuel nozzle.

From the diagnostic computer, the jitter is caused by the failure of the third cylinder.

During the start-up process, the crankshaft will be reversed, and the intake manifold will be tamped.The car's idle speed is unstable and the jitter is serious, which is similar to the failure of the car's lack of cylinder. The acceleration of the car is insufficient, and the car can't run, and the speed exceeds 2,500 rm. The vehicle has high fuel consumption, the exhaust emissions exceed the standard, and the exhaust pipe will produce black smoke.

Solution: Check whether the spark plug has too much carbon and replace the spark plug.

The main reason for idling jitter; the most common reason for car jitter is that the throttle valve is too dirty or the fuel injector has too much carbon.

This may be caused by excessive carbon accumulation in the intake airway, or it may be caused by lack of cylinder. The lack of cylinder is caused by a problem with the ignition system. After this situation occurs, it is recommended to clean up the carbon accumulation in the airway, and then check the ignition system.
