MANTILLA GONZALEZ, Juan Miguel; RONCANCIO GOMEZ, Jorge  e  GALEANO URUENA, Carlos Humberto. Performance and Emissions Study of an Internal Combustion Engine with Dual Fuel Diesel-Natural Gas. Energética [online]. 2015, vol.36, n.1, pp. 27-37. ISSN 1815-5901.

Many of the problems reported for dual diesel-natural gas systems occur due to poor gas dosage. For this reason a natural gas electronic injection feeding system was adapted to a compression ignitios internal combustion engine. An experimental design controlling the natural gas dosage is considered. As a result a comparative analysis between performance and emissions from the Diesel-and diesel-Natural Gas operation is obtained. From this analysis it is possible to see that engine performance is not affected by operation of the engine under the dual mode, i.e. the motor running under dual mode can support the loads applied to the engine. It is also observed that the volumetric efficiency improves under all conditions of operation and emissions from the dual mode of operation are better only when working at high engine loads.

Palavras-chave : diesel engine performance; emissions of diesel engines; natural gas; dual fuel induction systems.
