Westport and Scania preliminary testing exhibits H₂ HPDI delivers peak BTE of 51.5% at mid-load


Westport Gasoline Methods and Scania AB introduced preliminary engine take a look at outcomes of Westport’s H₂ HPDI gasoline system for heavy-duty car purposes (earlier put up). Westport’s HPDI gasoline system know-how permits heavy-duty vehicles to function on pure fuel with the identical energy, torque, effectivity, and efficiency as diesel engines. H2 HPDI operates the system with hydrogen.

The joint demonstration program between Westport and Scania checks the capabilities of the H₂ HPDI gasoline system as utilized to the Scania 13-Liter CBE1 platform, Scania’s next-generation, best-in-class engine supposed for Euro VII on-highway emission requirements.

Scania’s engine fulfils the strictest exhaust emission necessities with low gasoline consumption and excessive torque. When utilizing Westport’s HPDI know-how fueled with hydrogen, the early take a look at outcomes present efficiency with a peak Brake Thermal Effectivity of 51.5% complemented by 48.7% at street load situations, all with engine-out NOx much like the bottom diesel engine, which is suitable with Euro VII and EPA27.


Westport’s experience is in working with gaseous fuels. Hydrogen use in an inner combustion engine with our HPDI gasoline system is an inexpensive pathway to make use of a zero-carbon gasoline utilizing present engine structure and present manufacturing infrastructure. This thrilling evolution of our patented know-how gives better efficiency whereas reaching dramatically lowered emissions.

—David M. Johnson, CEO of Westport Gasoline Methods

The H₂ HPDI idea requires restricted redesign of the diesel cylinder head and no redesign of the exterior fuel alternate system, exhaust aftertreatment system or crank case air flow system, whereas offering excessive low-end torque—28bar BMEP at 900rpm—and glorious transient efficiency. This permits a short while to market with a wonderful product related to low investments, and might be a complement to battery electrical autos, particularly for lengthy haulage and places with restricted electrical infrastructure.

—Eric Olofsson, senior technical advisor at Scania

The businesses anticipate to finish the preliminary engine testing within the coming month, earlier than persevering with with the following step. Hydrogen use in an inner combustion engine with the H₂ HPDI gasoline system is a cost-competitive pathway with present know-how to make use of a zero-carbon gasoline to energy heavy-duty transportation purposes that require strong and dependable options.
