Brake thermal efficiency equation
WebMay 14, 2013 · Thermal Efficiency, Brake = 1/ (bSPC x QHV) bSPC (brake Specific fuel consumption) = 0.396 kg/KWh. QHV (Heating Value for fuel) = 44 MJ/Kg. The correct … WebJun 30, 2007 · Data analysis indicated that the use of hydrogen/natural gas fuel blend penalizes the engine operation with a 1.5 to 2.0% decrease in torque, but provided up to a 36% reduction in CO, a 30% reduction in NOX, and a 5% increase in brake thermal efficiency. These results concur with previous results published in the open literature.
