Does BMW Have a Particulate Filter?

Since the second half of 2020, BMW has installed particulate filters in all its vehicles to comply with the China VI-B emission standards. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, designed to capture particulate emissions before they enter the atmosphere. It can reduce soot emissions from diesel engines by more than 90%, and the captured particulate matter is subsequently burned off during vehicle operation. How the particulate filter works: The diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the particulate filter through a dedicated pipe. The densely arranged bag filters inside the device capture the carbon particles on a metal fiber felt filter. When the accumulated particulate matter reaches a certain level, the burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide. To check if a BMW is equipped with a particulate filter, you can use the following three methods: 1. Check the and to see if the particulate filter function is mentioned. Additionally, carefully review the fault codes in the manual to check for a "particulate filter" warning light indicator. 2. Look at the label on the oil filler cap. If the cap clearly specifies 0W-20 grade oil, it indicates the presence of a particulate filter. 3. Inspect the exhaust pipe behind the catalytic converter to see if there is an additional cylindrical section. If present, it is the particulate filter.

How Much Fuel Additive Should Be Added to a Motorcycle at Once?

Motorcycle fuel additive should be analyzed based on actual conditions. If the fuel tank has a large capacity, more fuel additive is needed; conversely, less should be added. Similarly, if the fuel additive is highly effective, a smaller amount can also be used. Generally, for fuel tanks within 60 liters, adding about 300ml of fuel additive at once is sufficient. Fuel additive is a general term for the third generation of gasoline detergent, designed to solve carbon deposit issues in the fuel system of electronic fuel injection vehicles, quickly restore the engine's optimal working condition, compensate for certain performance deficiencies of gasoline, and endow gasoline with some new excellent characteristics, such as improving atomization, reducing wear, protecting the engine, and reducing emissions. Currently, there are many brands of fuel additives on the market, with varying quality. When purchasing, it is essential to choose genuine products and avoid using irregular products recommended by repair shops or gas stations to prevent unnecessary losses.
