VILLAMAR, Carlos G; FYGUEROA, Simón J y MARTIN, María J. Effect of Some Parameters on the Performance of a Compression Ignition Engine. Inf. tecnol. [online]. 2009, vol.20, n.1, pp. 67-72. ISSN 0718-0764. http://dx.doi.org/10.4067/S0718-07642009000100008.
Some parametric studies on the thermodynamic cycle of a compression ignition engine by using a computer program that allows to analyze the cycle considering variations of working fluid composition and fluid properties due to pressure, temperature and fuel/air ratio. Studies on the influence of main indexes of the engine on the average pressure and temperature of the gases in the cylinder were done. Among these, the starting angle, the ignition time and duration of the combustion, the equivalence ratio, and gas recirculation, were considered. It is concluded that an increase in combustion duration implies a richness increase to maintain the power, and that nitrogen oxide emissions are reduced by gas recirculation.
