Análisis de las prestaciones de un motor de combustión interna alternativo usando biocombustibles: (i) aceite de soya; (ii) aceite de canola

Abstract

In the present study, two biofuels derived from cooking oil are evaluated. To carry out this work, an reciprocating internal combustion engine will be used, which is ready on a fully instrumented engine test bench. Firstly, the biodiesel production process is described, where soybean oil and canola oil have been used. Subsequently, the experimental section that has been used for the present investigation is described. The experimental tests are carried out: (i) modifying the degree of opening of the accelerator and (ii) using a constant load of the dynamometer. On the other hand, in the results section shows the performance of the two biofuels generated against diesel commercial. Also, in this section shows the percentage differences of: (i) engine power; (ii) mass fuel, (iii) thermal efficiency engine and, (iv) exhaust temperaturas. The tests have been carried out under different engine speed conditions of the reciprocating internal combustion engine. Where, the main average differences that have been registered in the engine test bench were: for engine power, 32 and 33%; for the mass fuel consumption of -4.5 and 5%, when using soybean biodiesel and canola biodiesel, respectively. These differences are due to the energy capacity of each biofuel and, the instantaneous evolution of combustion process inside the reciprocating internal combustion engine.
