On March 1 local time, Weichai Power North America's three gas engines-WP10GNA, WP10GTA and WP13GTA were certified by EPA in the U.S. Combined with previously certified WP6GNA and WP6GTA, Weichai Power's five gas engines specific to North America have all been certified by EPA, marking that its products will fully enter the North American non-road gas engine market.
As a high-end market, North America has strict non-road emission regulations. In the past two years, the Weifang headquarters and North American R&D team of Weichai Power have worked in close collaboration and jointly overcome difficulty, to gain access to the North American market for all the five products. These products feature E-controls, theoretical air-fuel ratio + three-way catalysis, wide applicable scope of fuels, and strict closed-loop control of air-fuel ratio leading to near zero emission. WP6GNA and WP10GNA which have gone into mass production are mainly applied in segments including oil & gas fields, agricultural irrigation and generating sets. During market validation synchronizing with development, they were praised by customers for their stable performance and outstanding quality.
