Does the Emgrand GL have a particulate filter?
2 Answers
Emgrand GL is equipped with a particulate filter. All Geely vehicles with turbocharged engines come with particulate filters. 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 exhaust particulate trap through a dedicated pipeline. After passing through its densely arranged bag-type filter, the carbon particles are adsorbed on a filter made of metal fiber felt. When the amount of adsorbed particles reaches a certain level, the burner at the end automatically ignites and burns, converting the adsorbed carbon particles into harmless carbon dioxide that is then expelled. 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.
As a long-time owner of the Emgrand GL, I've driven both the 2019 and 2022 models. The China V compliant 2019 version indeed didn't come with a particulate filter, but all China VI-b models released after 2021 are equipped with this device. You can spot it as that bulge in the middle section of the exhaust pipe. This component mainly captures carbon particles from exhaust emissions, but prolonged city driving can trigger blockage warnings. Just last week, I performed a high-speed regeneration by revving the engine, and the dashboard warning light went off. The newer models have relocated the GPF behind the engine for faster heating, making it less prone to clogging.
