Abstract:
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.
