BMW Mini R55 engine n16 left tatter

1. There is an abnormal sound in the engine. Symptoms: There is a high possibility of abnormal noise in the engine compartment. Most people also judge from the sound source that it is the abnormal sound of the engine compartment, usually a harsh sound. Or the strange sound of wind whistle. Solution: The technical status of a certain mechanism of the engine has changed.

2. Change the original transmission oil,Replace a set of spark plugs, clean the throttle valve, and clean the throttle valve. The throttle valve cleaning is generally carried out every 20,000 kilometers. When cleaning, the carburetizer cleaner should be used to deal with stains. Some cars need to be matched after cleaning, and some cars do not need to, which can reduce fuel consumption and reduce the problem of vehicle start-up jitter.

3. Engine factors: the oil return hole is blocked, the oil cannot be returned normally to the crankcase, the cylinder wall and piston are worn, the valve oil seal and the crankshaft oil seal gap are too large to corrode and age, resulting in oil leakage; if there is a problem with the sealing, the working surface cannot be lubricated by the lubricating oil, and the wear will be very serious.

What's wrong with the lack of fire in the BMW minin164 cylinder

The lack of fire in the BMW minin164 cylinder is a problem with spark plugs and fire coils.If you want to investigate the cause of the fire, first check whether the spark plug is not burning well, whether the gap is too large, and whether it needs to be replaced if it is too large.

It is recommended to check the carbon accumulation status of 3 cylinders and 4 cylinders, most of which are caused by too much carbon accumulation, and the cylinder pressure is insufficient. I hope it will be helpful to you.

According to the analysis, the reason for this phenomenon is that the engine speed was too high in the past, so that the valve could not return completely, resulting in the putter to detach from the hydraulic support. Figure 6 The valve putter comes out, troubleshoots, resets the putter, and confirms the troubleshooting after debugging.

The difference between the mini n18 and n16 engine

1. The N13 engine is very similar to the N18 engine, but there are some structural changes to adapt to the longitudinal rear drive platform of Series 1.The numbering of the whole N1X series looks a little strange at first glance. The numbering span of each upgraded version is relatively large, but it is also quite regular.

2. The Peugeot 6t engine corresponds to BMW's N12N13N14N16 and N18 series engines used on BMW 1 series 3 series and mini. Among them, the power engine of thp and BMW are completely different from the technical standard version in VANOS technology. Take Peugeot 408 as an example.

3. High-pressure oil pump failure. An engine is a machine that can convert other forms of energy into mechanical energy. The fault of the high-pressure oil pump of the N18 engine equipped with mini is the same as the thermoster, oil leakage and oil burning of other parts, so the common problem of the mini n18 engine is the failure of the high-pressure oil pump.

4. It is basically the same, some parameters and control logic are different, and the N13 engine is vertical, which is used on BMW, while the N18 is a horizontal engine, which is used in MINI cars.

5. N18 oil label number MINI-N18: 2L. The meaning of the oil model is that the oil mark includes two parts: grading and viscosity specifications. Oil grading is represented by a combination of two letters.

6. BMW Mini R55 has a variety of engine models, including 6L N16L N16L N16 and 6L N18, etc. Therefore, it is impossible to determine whether it is specifically N engines, and it needs to be inquired and confirmed according to the specific model and year of the vehicle.
