Abstract

The use of alternative energy sources for internal combustion (IC) engines is being raised. The most promising fuel in such application is natural gas in gaseous state, which mainly consists methane. It is mainly being used as an engine fuel for both monofuel and dual fuel configuration. Many investigations confirmed the benefits of application of dual fuel compression ignition engine fuelled with natural gas. The aim of this paper is analysis of engine operation parameters and emissions for two different locations of gas injector in the inlet duct. The operation parameters and NO_x emission from this research are presented and compared for different natural gas shares in total energy delivered to the cylinder with fuel. The parameters are compared to monofuel operated engine.
