HHO and HHOCNG fuel mixtures examined and compared with neat diesel operation.
Pilot diesel injection & diesel fuel substitution are obtained with steeping motor.
Brake torque & power, SFC and BTE results were presented as performance analyses.
CO, CO2 and NOx results (including EGT) were illustrated as emission parameters.
Improvements of 25HHOCNG fuel are more promising compared to other test fuels.
