Mixture Maldistribution and Aldehyde Emission in an Alcohol Fueled S.I. Engine

This paper deals with the experimental results of two engines - one single cylinder RDH - CFR engine with variable compression ratio and the other a four cylinder variable speed automotive type engine. The single cylinder emission results are projected for multicylinder operation and for a fixed maldistribution symmetry. The results show that there is a reduction in NO_X emissions due to maldistribution where as UBF, CO and CH₂O emissions are increased due to maldistribution.
