THE IMPACT OF THE ADDITION DIMETHYL ETHER ON INTAKE MANIFOLD TO THE PERFORMANCE AND THE ENVIRONMENT OF DIESEL ENGINE

Abstract

Currently, Dimethyl Ether (DME) is one of the promising alternative fuel for
diesel engines. One effective solution to use DME for diesel engines is additional
DME on the intake manifold of engine. This paper presents the results of research
the impact of the addition DME on intake manifold to the performance and the
environment of diesel engine ISUZU 4BD1T using AVL- Boost simulation software.
The amount of DME is provided on the intake manifold at the rate of 5%, 10% and
15% of the energy external characteristic. The study results showed that the
addition of DME on the intake manifold of the engine changes insignificantly, NOx
and PM emissions decrease, CO emission increases as additional rate increases DME.
