In line with the market trend that NG buses have gradually become an integral part of the diversified development of bus fuels in the country, as the leader in China's engine industry, Yuchai has kept ahead in innovation and is committed to building professional NG engines meeting market demands.

By virtue of its tremendous R & D strength and persistence in engine business, Yuchai embarked upon gas engine R & D as early as in 1995, matched gas engines with vehicles in volume in 1998, launched gas engines in bulk in 2000 and accomplished the closed-loop support of experiment and R & D, thus developing several leading technologies. As the core representatives of Yuchai NG technologies, single-point injection and lean burn have boosted power and fuel economy.

Besides, the fourth-generation electronically-controlled single-point injection controls air-fuel ratio more precisely to better power performance. The emission capacity is up to National V standards, and system parts are highly reliable and easy to maintain. The use of mass specific parts can boost product stability in high-temperature combustion.
