Summary:

Globally, many jurisdictions are working toward greenhouse gas (GHG) emissions standards for medium- and heavy-duty vehicles that will take effect in the next decade and require GHG reductions of up to 25% from 2017 legislated levels. While diesel engines will require increasingly complex improvements, high pressure direct injection (HPDI) of natural gas can provide GHG reductions of approximately 20% (75% or more with renewable natural gas / bio-methane) while preserving the same power density, torque and performance as diesel.This paper will provide an overview of the improvements in the Westport HPDI 2.0 components as well as performance and emissions results demonstrated to-date. The potential and challenges of higher injection pressures will be explored while also investigating sources of and methods to eliminate methane venting on the vehicle
