STUDY PERFORMANCE AND EMISSION OF AN EFI MOTORCYCLE SUPPLEMENTED WITH HYDROGEN-RICH GAS DIRIVED FROM ON-BOARD Cu-Ni/Al2O3 CATALYST AFTER RUNNING 5.000KM

Abstract

Steam reforming of gasoline (SRG) Cu-Ni/ Al2O3 catalyst was used in a SI engine to convert a proportion of gasoline to rich-hydrogen gas with the aid of heat
generated from exhaust gas, the rich-hydrogen gas is then supplied to the engine in order to improve performance and emission quality. However, studying durability
of catalyst still not be executed. This article will study the economic specifications and emission of an EFI motorcycle using Cu-Ni/ Al2O3 catalyst after running durability
5000km. The comparing experiment was used in this study. The experiment was performed on Chassis Dynamometer 20”, analyzing - exhaust equipment CEBII and
Fuel balance 733S. The study has shown that after running durability, at load characteristics with different load levels, power decreased while fuel consumption
increased, at full load, avarage power decreased 1.82% and fuel consumption increased 2.02%. It also has shown that average CO and HC content increased by 1.89%
and 1.84%, while average NOx and CO2 decreased by 1.98% and 1.90%. The experiment pointed out, after running durability, hermetic chamber reduced, average
decreased 0.84%, catalytic metal particles tended to combine together, and appearing particles carbon was deposited on the surface of the Ni catalyst.
