Westport Innovations Inc. has completed an engineering program with Daimler AG to develop and assess the Westport High Pressure Direct Injection (HPDI) system for a Daimler heavy-duty engine. The prototype HPDI engine met all technical targets, resulting in a payment of EUR 2.4 million (approximately $2.7 million) by Daimler to Westport.
For competitive reasons, Westport says, further terms of the program have not been disclosed.
According to the engine manufacturer, Westport HPDI 2.0 is capable of delivering performance and fuel economy equivalent to that of current high-performance diesel-fueled engines, but with diesel substitution of over 90%. The company says this combination of high performance and high efficiency is critical for heavy-duty engines in demanding commercial applications.
Westport first revealed details about HPDI 2.0 in 2013. The system burns natural gas as the primary fuel, along with a small amount of diesel as an ignition source. Furthermore, Westport says HPDI 2.0 is designed to meet the latest in stringent emission regulations, including Euro VI and EPA 2014.
