Abstract

In this article, the issues related to vehicular traffic in big cities and heightened harmful substance emissions stemming from it were described. In the research part, the effect of air leakage in the SI engine intake manifold on substance emissions was investigated. The manifold was customized to simulate air leakage in each of its air ducts. Same ratio of leakage was assumed for each duct, and substance emissions were measured in full range of engine rotational speeds. A difference in exhaust gas composition was shown for each researched variant, being the result of varying cylinder filling ratio due to simulated air leakage.
