As everyone konws, engine is the decisive element to decide auto's emission level and performance of complete vehicle, though all domestic manfacuturers have their own advantages of technologies, to clients, economy, reliability and after service are the most important for them to make decisions.

Exhausted gas emission is half of previous national II emission standard compared with natinal III, but many commercial vehicles users find that oil consumption has gone up with upgrading of emission standard, so they complain "emission reducing but no energy saving any more". How does this phenomena happen? Some resources releases that many manufacturers are short eyes to upgrade emission standard, but due to limit to realize technology of engines, they have to immolate oil consumption of engines and other permances.
