Gasoline cars usually do not have DPF function. DPF， The Diesel Particulate Filter is a device specifically installed in the emission system of diesel vehicles. It can effectively filter out tiny particles in the emitted gas, prevent toxic tiny particles from being emitted from car exhaust, and thus reduce environmental pollution. DPF equipment usually consists of a mixed surface and internal filtration system, which can efficiently filter out 70% to 90% of particulate matter in the exhaust, and the filtration efficiency can even reach 98% for particulate matter with a particle size greater than 0.04 μ m.

In contrast, the emissions of gasoline cars are mainly gases such as carbon dioxide and carbon monoxide, which are relatively harmless, so gasoline cars usually do not need to be equipped with DPF. However, with increasingly strict environmental regulations, some gasoline vehicles may also adopt similar particulate matter capture technologies to meet emission standards, but this is not a common phenomenon.

Overall, if you own a gasoline car, it is likely that it is not equipped with DPF function. If you have any questions about the emission system of your car or need further environmental advice, it is recommended to consult professional car maintenance personnel or environmental organizations.
