Slide 6: An Overview of Westport's HPDI Fuel System
An Overview of Westport’s HPDI™ Fuel System Westport’s HPDITM fuel system was conceptualized ~30 years ago with the goal of creating a more efficient natural gas engine. The “heart” of the system is a unique fuel injector which features a small pilot injection and a larger primary injection of t

Slide 8: H2 HPDI Combustion Overview
H2 HPDI Combustion Overview The following results will focus on the initial calibration of Scania’s state-of-the-art 13-litre CBE1 platform – Commercially available HPDI fuel system hardware was used for the initial calibration and demonstration of the H2 HPDI fuel system In parallel, hydrogen w
Slide 9: H2 Combustion on Scania CBE1 Engine
H2 Combustion on Scania CBE1 Engine BTE on torque curve of ~47-49% Peak BTE at 51.5% Engine-out NOx levels calibrated to ~6-12 g/kW.h to reflect EATs strategy Note: EGR can be used to reduce NOx further to ~3g/kW.hr Pilot quantities as low as 2-3mg have been tested, equating to near-zero C
Slide 10: Minimal H2 Slip
Minimal H2 Slip H2 combustion is almost fully complete ηCombustion(H2) is > 99.97% at the measured A-speed points No measurable slip infers a low risk of H2 interaction with combustion chamber 10 44TH INTERNATIONAL VIENNA MOTOR SYMPOSIUM 2023

Slide 12: Next Generation Fuel System Architecture (LNG Shown)
Next Generation Fuel System Architecture (LNG Shown) Revised approach to gas pressure control Eliminates dynamic venting Facilitates higher pressures (eliminates non-metallic seals) Capable of OBFCM for EU VII 12 44TH INTERNATIONAL VIENNA MOTOR SYMPOSIUM 2023
Slide 13: H2 Fuel System: Off-Engine Approach
H2 Fuel System: Off-Engine Approach Target for onboard fuel is 80kg – equates to ~2050- litres of storage – Note: H2 does not follow ideal gas law at higher pressures: 40% over- estimate for ideal gas calculation Range without compressor is less than 600km 13 44TH INTERNATIONAL VIENNA MOTOR SYMP
Slide 14: H2 Smart Tank System
H2 Smart Tank System Compressor required for ranges greater than 500km Smart Tank strategy evolved to maximize efficiency and minimize compressor flow Able to reduce size, weight and power requirement. 14 44TH INTERNATIONAL VIENNA MOTOR SYMPOSIUM 2023

Slide 18: H2 Demonstration Trucks
H2 Demonstration Trucks Westport has built two H2 HPDI demonstration trucks – Both trucks are converted from commercially available NG European models – Truck #1 is US-based – Truck #2 is European based Onboard storage is currently 16kg in a four-tank array with no compressor 18 44TH INTERNATION
Slide 19: H2 Demonstration Trucks – Challenges & Next Steps
H2 Demonstration Trucks – Challenges & Next Steps Challenges: – Permitting – Fueling Next steps: – Increase fuel storage: • 80kg of fuel with no compressor will allow up to ~600km range* with Smart Tank strategies – Add compressor: * Cycle/load dependent • 80kg of fuel w/ compressor will allow u
Slide 20: Summary
Summary Westport’s HPDI fuel system can be used with the same base diesel engine – same engine architecture for Biomethane or Hydrogen. Interest in Westport’s H2 HPDI fuel system is growing from OEMs, with multiple development projects recently announced and underway. The SCANIA CBE1 engine eq
