To reduce pollutant emission of gasoline engine during cold start, ZSM-5 zeolite was
selected as adsorbent and coated on cordierite carrier and encapsulated as a hydrocarbon …

In order to reduce HC emission of the gasoline engine during cold start to meet increasingly
stringent emission standards, an adsorptive catalytic gasoline particulate filter (A-CGPF) is …

In this work, cold start experiments results showed that the HC catcher coated with 1% iron
content is more effective than that with 3% iron content, the peak HC emission is reduced …

In this paper, a hydrocarbon (HC) adsorber and converter (HCAC) system is proposed for
hydrocarbon emission control during cold start (Hydrocarbons are adsorbed in HC adsorber …

80% of the hydrocarbons in gasoline engine emissions come from during cold starts.
Zeolites are often used to adsorb HCs during gasoline engine cold-starting. In order to …

In order to reduce tail-pipe hydrocarbon emissions from SI gasoline engines, rapid catalyst
warm-up and improvement of catalyst conversion efficiency are important. There are many …
