Diesel oxidation catalysts of 16 Euro 4 passenger cars were analyzed and tested on an engine bench to attempt to correlate composition and structure to real-life performances. Particular low temperature behavior was evidenced, which was further studied using simplified gas mixtures on a synthetic gas bench. The long chain hydrocarbons are efficiently trapped, while NO 2 plays a major role in CO abatement before the activation of the catalytic oxidation by O 2 .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
