What is the reason for the blockage of BMW x3 particle filter?
The BMW x3 particulate trap is blocked for the following reasons:
GPF can capture particles outside the three-way catalyst, so after driving for a long time, a large number of tiny particles will accumulate on GPF, and the particle trap will be blocked over time. In addition, if the engine is idling for a long time, the stop-and-go road conditions in urban areas will also cause GPF congestion. This is because the working temperature of GPF is low at this time, and it cannot be effectively regenerated, so a vicious circle will occur.
After the GPF is blocked, it will lead to poor exhaust, increased exhaust pressure, decreased vehicle power and increased fuel consumption. Serious blockage of GPF may also cause the vehicle to fail to start normally.
Principle of particle trap:
Metal platinum, rhodium and palladium are sprayed on a diesel particulate filter, black smoke containing carbon particles discharged by the diesel engine enters an engine exhaust particulate trap through a special pipeline, and carbon smoke particles are adsorbed on a filter made of metal fiber felt through a closely arranged bag filter in the diesel particulate filter; When the particle adsorption capacity reaches a certain level, the burner at the end automatically ignites and burns the soot particles adsorbed on it, and converts them into harmless carbon dioxide to be discharged.
Does BMW x3 hurt the turbine in sport mode?
Starting the sport mode of BMW x3 will not harm the turbine, but only adjust the power output of the engine relatively.
Economic model:
Eco is an economical model of BMW x3, which sacrifices certain engine power to achieve relatively low fuel consumption.
Motion mode:
The SPO next to the shift key is a sport mode, and the gearbox can shift gears freely to obtain greater torque output and acceleration.
Comfort mode:
It is a basic mode and a comfortable mode when leaving the factory.
Introduction:
BMW X3 is an SUV with unique personality. It introduces the concept of a brand-new SUV sport utility vehicle, and is equipped with BMW patented xDrive intelligent all-wheel drive system, which combines the unique shape proportion and classic innovative design of the sport utility vehicle, with a fresh and young appearance. At the same time, it also emphasizes the design characteristics of BMW brand, which is strong and powerful.
