Westport, Weichai Initiate Development of WD10 Engine with HPDI 2.0 Technology

Westport Innovations announced the launch of final customer validation units of the next generation Westport high pressure direct injection (Westport™ HPDI 2.0) on the Weichai Westport WP12 engine platform.

The Weichai Westport WP 12 HPDI is China’s first engine featuring Westport HPDI technology, delivering the power and performance of the base diesel engine, while replacing up to 95% of diesel fuel with cleaner burning, less expensive natural gas. Weichai Westport plans to release 30 trucks for customer validation through 2014 with factory production expected to start in 2015. The WP12 with Westport HPDI 2.0 will be certified to be compliant with China V emissions standards.

As part of Weichai’s ongoing commitment to running clean-burning, lower-cost natural gas and offering its customers diesel-like performance, Weichai and Westport have agreed to develop the 10 litre Weichai Westport WD10 engine with Westport HPDI 2.0. Weichai Westport will provide funding for the development with Westport supplying key components and engineering support. Due to the commonality with the WP12, the program is expected to take approximately two years with product availability planned for 2016.  The current generation Weichai Westport WD10 and WP12 natural gas engines, using lean burn spark ignited technology, account for about 75 percent of Weichai Westport’s engine unit sales.

“We are entering the largest market for natural gas trucks demonstrated by our joint venture with over 60,000 natural gas engines sold by Weichai Westport in the last two years, a growth of approximately 100 percent year over year,” said David Demers, CEO of Westport. “We have not only found common ground for success in China but are forging ahead with a second program aimed at making the benefits of advanced Westport HPDI 2.0 technology available on the majority of the natural gas engines sold by Weichai Westport.”
