FEV mixes gasoline combustion

摘要

Powertrain firm FEV is working on a highly stratified compression ignition combustion process for gasoline engines. The aim is to deliver high efficiency and very low NOx emissions so a three-way catalyst is the only aftertreatment needed.rnLean-burn spark-ignition engines offer better economy than conventional gasoline units but the expensive NOx aftertreatment they require is a turn-off for OEMs. FEV's proposal gets around this without resorting to anything as complex as homogeneous charge compression ignition (HCCI) strategies.
