Abstract Diesel engine using lean-burn technology is arisen due to the big push
driving from energy saving and exhaust reduction researches on the main
diesel emission (PM and NO x ) for fuel properties，new engine technologies，and
after-treatment technologies are composition and harm have been introduced and the purification technology of particle materials and NOx in diesel
exhaust has been discussed. Meanwhile the existing problems of each technology are analyzed, as well as the development trend is brought forward.
