VOLPATO, Carlos Eduardo Silva; CONDE, Alexon do Prado; BARBOSA, Jackson Antonio  e  SALVADOR, Nilson. Performance of four stroke diesel cycle engine supplied with soybean oil biodiesel (B 100). Ciênc. agrotec. [online]. 2009, vol.33, n.4, pp.1125-1130. ISSN 1413-7054.  https://doi.org/10.1590/S1413-70542009000400025.

The aim of this work was to compare the performance of a four stroke diesel cycle engine and a four cylinder using biodiesel made from soy oil (B100), in comparison with the diesel oil. The parameters analyzed were: effective power and reduced power, torque, specific and energetic consumption of fuel, thermal-mechanics and volumetric efficiency. An entirely randomized experiment design was installed (DIC) in a factorial structure, the analysis of variance was carried out and the Tukey test was applied at the level of 5%. Five rotation levels were researched in four replications (650, 570, 490, 410, 320, and 240 rpm). The engine fed with biodiesel presented torque and reduced power a little lower than the engine fed with fossil diesel. However, specific and hourly consumptions presented more satisfactory results.

Palavras-chave : Alternative fuel; energy efficiency; combustion engine.
