Abstract

This paper presents experimental results to determine the effect of HHO addition on the intake manifold on emission patterns of cars using older generation diesel engines. The experimental car is an Isuzu Hilander car manufactured in 2005. The experiment was conducted with an engine speed of 1500 rpm with different loads. The research results have showed when HHO gas is added to the intake manifold, most of the harmful emissions are reduced. Namely, smoke emission decreased by an average of 26,4%; CO emissions reduced by an average of 13,75%; HC emissions decreased by an average of 32,32%. Particularly, NOx emissions increased by an average of 12,03%.
