Abstract: Diesel engine has advantages of low fuel consumption, high torque output and wide power range,
and has been widely used in transportation and engineering machinery as a power. The diesel powered
vehicles can only meet future stringent emission regulations using aftertreatment devices. This paper compared
the different vehicle emission regulations in Europe, the USA, Japan and China, and analyzed in-cylinder and
aftertreatment technical approaches to meet the emission regulations for light-duty and heavy-duty diesel
vehicles. The research status of the mainstream aftertreatment technologies like diesel oxidation catalyst (DOC),
nitrogen oxides (NOx) selective catalytic reduction (SCR), lean NOx trap (LNT) and diesel particulate filter (DPF)
was described and discussed. The future development of the diesel emission regulations and aftertreatment
technologies was prospected.

Key words: diesel engine, emission regulation, aftertreatment, selective catalytic reduction (SCR), diesel particulate filter (DPF)
