Fuel Consumption And Emissions Testing Of The HydraGenTM Unit On A Class 8 Truck While Exposed To Real World Road Load And Environmental Conditions Was Carried Out Using The Climatic Wind Tunnel (CWT) Of The Automotive Centre Of Excellence (ACE) At The University Of Ontario Institute Of Technology (UOIT) In Oshawa, Ontario.

The objective of this dynamometer testing was to simulate real‐life environments with high accuracy and repeatable conditions on an in‐service Class 8 truck to determine how much H2/O2 was required for a minimum of 8% fuel reduction while at the same time maintaining the same power and torque.

Fuel consumption was measured by rerouting the fuel supply system to an external fuel drum placed on a precision scale. As fuel was consumed the scale measured the weight of the drum over the time of the test. The fuel weight and time were recorded by the CWT data acquisition system. Emissions were measured by using the HydraGenTM portable emission equipment.

Several trials were done with two different Class 8 tractors at different combinations of velocity, force load and H2/O2 settings.

There was 20+ hours of testing completed producing over 550 pages of valuable data which has been instrumental in the further development and algorithms for our new Smart ECU.

While altering flow of gases, and depending on different settings of H2/O2, test results verified a range of fuel consumption reductions from 2.7% to 19.2% equally on post EGR and pre‐EGR engines.

Emission reduction ranged from 10% to 40% of greenhouse gases (Carbon Monoxide, Carbon Dioxide, Nitrogen Oxide) and greater than 65% reduction in particulate matter.


ACE is a research and testing facility that offers chambers and technology for climatic, structural durability and life‐ cycle testing and research. Facilities include one of the largest and most sophisticated climatic wind tunnels on the planet. In this test chamber, wind speeds can reach 280 kph with temperatures that range from ‐40 to +60°C. With our solar arrays and storm generators we can create any weather condition imaginable from sweltering jungle downpours to the paralyzing cold of an arctic storm. We use these chambers to test automotive and aerospace products, to improve the performance of elite athletes and to provide services to many other markets including the Unmanned Aerial Vehicle industry.
