Does the Geely Emgrand have a particulate filter?
2 Answers
Geely Emgrand 2021 model is equipped with a particulate filter. Function of the particulate filter: The particulate filter can reduce the soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Principle of the particulate filter: 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 engine exhaust particulate trap through a dedicated pipeline. After passing through its densely arranged bag-type filter, the carbon particles are adsorbed on the filter made of metal fiber felt. When the adsorption of particles reaches a certain level, the burner at the end automatically ignites and burns, turning the adsorbed carbon particles into harmless carbon dioxide that is then expelled.
As someone who's been in the automotive circle for years, I'm quite familiar with Geely Emgrand's emission system. The particulate filter is mainly used in diesel engines to filter out black smoke particles from exhaust gases, typically found in trucks or some European diesel sedans. Domestic gasoline cars like the Emgrand mostly come standard with gasoline engines, which don't require particulate filters at all. Instead, they rely on a three-way catalytic converter to handle emissions—it converts harmful gases like carbon monoxide into harmless substances. With the stringent China VI emission standards now in place, the gasoline version of the Emgrand has already met the requirements through engine optimization, making it completely unnecessary to install such a device. When driving, I've also noticed that the engine runs smoothly, maintenance is straightforward, and unlike diesel cars that often require DPF clogging cleanups, it's hassle-free and cost-effective. If you're driving a gasoline-powered Emgrand, don't worry unnecessarily about the particulate filter—it genuinely doesn't have one. Just make sure to regularly check the three-way catalytic converter to keep it functioning properly.
