Abstract

Natural gas combustion in diesel engine environment: experiments and computations C. Mansour, A. Bounif & A. Aris Universite des Sciences et de la Technologic d'Oran, Algerie Abstract The aim of this paper is to investigate the emission and performance characteristics of a commercial diesel engine (Deutz FL8 413F) being operated on natural gas with pilot diesel ignition. In parallel, a numerical simulation of the Gas-Diesel (Dual-fuel) engine has been carried with a modified Perfect Stirred Reactor (PSR-Chemkin ) code. A large number of reaction intermediates were identified, and their concentrations were followed for reaction yield ranging from low conversion to the formation of the final products. A detailed chemical kinetic reaction mechanism describing the natural gas oxidation and NO% reduction was built to produce the experimental results. The experimental emission concentrations are compared with the predictions of the model. A reasonably good prediction of the emis
