Research on Effects of Additional Brown’s Gas on The Working Emission Characteristics of Diesel Engine

Abstract

The paper presents simulation results aimed at determining the effects of Brown’s gas addition into the intake manifold of a diesel engine on operating characteristics and exhaust emissions along the external characteristic curve. The investigated engine is the IVECO 8140.43R, and the simulation tool employed is AVL Boost. The results indicate that with a Brown’s gas substitution rate of 10÷20% of the torque, the average torque increases by 17%, power output increases by 25%, brake specific fuel consumption decreases by 20%, NOx emissions increase by 11,3% on average, soot emissions decrease by 13,7%, and CO emissions decrease by 25% on average.
