RESEARCH TO ENHANCE ENGINEERING FEATURES AND EMISSIONS OF RV165 ENGINE BY IMPROVEMENT OF INTAKE MANIFOLD STRUCTURE

Abstract

In our country today, the trend of agricultural mechanization has made the
number of diesel engines for agricultural machines increase rapidly in both quantity
and type. However, these engines have low engineering fearture, especially high
emission levels which causing air pollution, affecting the health of the community.
Many methods have been considered to reduce engine emissions, among which
improving the intake manifold profile is a promising research direction. This paper
will use the simulation software Ansys-ICE and AVL-Boost to study and evaluate the
enhancement of engineering feature and toxic emissions when improving the
intake manifold of the RV165 diesel engine. Research results show that the
improved engine has reduced CO and PM emissions by 7.48% and 12.17%
compared to the original structure
