Catalytic Emission Control for Portable SI Engine Generator Sets 2001-28-0047

Emission regulations for portable generator sets have been enforced in India from June, 2000 and more and more stringent standards are in offing. Studies on application of monolith and packed bed oxidation catalytic converters on a two-stroke gasoline and 4-stroke kerosene fuelled SI engine generator sets were carried out. Substantial reductions in HC (unburned hydrocarbons) and CO (carbon monoxide) emissions were obtained on the 2-stroke generator even without secondary air and it could meet the June 2001 standards. For functioning of the catalytic converters on kerosene generator, secondary air had to be introduced. Although, significant reduction in CO were obtained, for improving conversion of HC, improvements in catalyst formulation and optimization of secondary air are to be done.
