Westport to Launch High-Pressure CNG Fuel System at ACT Expo
According to Westport, this marks a critical step toward commercializing HPDI technology with CNG for the North American heavy‑duty market, where CNG is preferred and demand for practical, cost-effective, lower‑emission diesel alternatives continues to grow
Canadian company Westport announced the first North American demonstration of its compressed natural gas (CNG) fuel storage system combined with the patented on-engine HPDI fuel system of Cespira, Westport’s joint venture with Volvo Group, at ACT Expo 2026. The exhibition is about to start in Las Vegas.
Wesport to Power CNG Volvo VNL Trucks
At ACT Expo, these systems are installed on a latest-generation Volvo VNL 300 truck with 500 horsepower and 1,850 lb-ft of torque, and with fuel efficiency on CNG closely comparable to the VNL running on diesel fuel. For the first time, Westport is showcasing the system in real‑world operation in a demonstration truck. This marks a critical step toward commercializing HPDI technology with CNG for the North American heavy‑duty market, where CNG is preferred and demand for practical, cost-effective, lower‑emission diesel alternatives continues to grow.
Westport’s high‑pressure (~700 bar) CNG platform is engineered for diesel combustion engines that require in‑cylinder, high‑pressure gaseous fuel injection, including engines equipped with the HPDI fuel system developed by Cespira.
“Showcasing our next‑generation high‑pressure CNG system at ACT Expo marks a defining milestone for the future of clean transportation,” said Westport CEO Dan Sceli. “By combining advanced high‑pressure storage with Cespira’s proven HPDI fuel systems, we’re demonstrating that fleets can achieve diesel performance and efficiency using widely available natural gas. This is more than a product introduction—it’s a meaningful step toward delivering real emissions reductions with compelling operating economics for the North American market.”
