Hydrogen Boost Dynamometer Test Results

 

        On February 25, 2010 a Hydrogen Boost electrolyzer (powered by a pair of battery chargers) was installed onto a 2004 Series 60 12.7 liter Detroit Diesel Engine rated at 515 horsepower attached to a dynamometer at the University of Northwestern Ohio. 

        Pictures below show the engine, dynamometer, control console, and university staff.

 

 

 

        Data was collected at 100hp, 200hp, 300hp, and 400hp at both 1400 rpm and 1800 rpm.  The data collected included RPM, intake air temperature measured at the intake manifold, Turbo Boost pressure measured after the air to air heat exchanger, exhaust gas temperature, torque, carbon monoxide emissions, NOx emissions, carbon dioxide percent in exhaust gases, and oxygen percent in exhaust gases, and mass of fuel used over each two minute period (measured with digital scales by reading the mass of the fuel tank before and after the two minute test intervals).  This series of tests was repeated three times, once with no hydrogen production, once with the electrolyzer running at 32 amps average, and once with the electrolyzer running at 46 amps average.  Data was recorded by hand since there was no capability to collect all the data with the same computer.  No data was available for hydrocarbon emissions because the gas analyzer used for that was inoperative.  Also the opacity of particulate matter in the exhaust was unable to be accurately measured because of equipment malfunction.

        Below is a graph of the fuel used during each two minute session, measured in kilograms.

 

          Below is a graph of the same data but expressed as a fuel flow rate in gallons per hour.

Average reduction in fuel flow using 32 Amps on the electrolyzer was 9.28%.

Average reduction in fuel flow using 46 Amps on the electrolyzer was 11.3%.

Average exhaust gas temperature increase using 32 Amps was 5.2%.

Average exhaust gas temperature increase using 46 Amps was 7.9%.

Average reduction in Carbon monoxide emissions using 32 Amps was 19%.

Average reduction in Carbon monoxide emissions using 46 Amps was 10.2%.

Average reduction in NOx emissions using 32 Amps was 5.8%.

Average reduction in NOx emissions using 46 Amps was 6.5%.

No operable equipment was available to measure unburned hydrocarbon emissions or particulate matter emissions.

Average reduction in total CO2 emissions is equivalent to the reduction in fuel flow stated above.

As expected, because of more complete burning of the fuel, the % CO2 in the exhaust increased and the % O2 decreased with the Hydrogen Boost.

Since power for the electrolyzer was furnished by an independent source, for comparison of a tractor trailer engine providing power to the electrolyzer by way of the alternator, the reduction in fuel flow would have been slightly less. The average power to the electrolyzer throughout the tests with hydrogen would have taken 0.73 horsepower.  The average horsepower output during the tests was 250 hp.  A 0.73 horsepower addition to that would have increase the fuel used by 0.3%.  The average fuel savings of over 10.3% would therefore be only 10.0% if the power to the electrolyzer was provided by the alternator.  This is consistent with Hydrogen Boost’s experience with dynamometer testing and in testing on Tractor trailer trucks using ECM reports to verify fuel savings.
