Semi-trailers use diesel fuel, which is divided into two main categories: light diesel and heavy diesel. Diesel engines have high power and traction, and trucks generally have large load capacities, so diesel engines are commonly used. Compared to gasoline, diesel has the characteristics of high energy density and low fuel consumption rate. More information about semi-trailers is as follows: Characteristics of semi-trailers: A semi-trailer is a trailer with axles placed behind the center of the vehicle (when the vehicle is evenly loaded) and equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. It is a heavy-duty transport vehicle connected to the semi-trailer head via a fifth wheel coupling. The national standard allows a semi-trailer's self-weight of up to 55 tons, but its load capacity can reach 200 tons. Classification of semi-trailers: Semi-trailers are generally three-axle trailers, with types including 11-meter warehouse-barrier semi-trailers, 13-meter warehouse-barrier semi-trailers, low-platform semi-trailers, etc. Vehicles with load capacities and dimensions similar to ordinary high-barrier trucks but weighing 15% or less are defined as light-duty vehicles.

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.
