Abstract
This work aims to analyze experimentally the methodologies to obtain specific fuel consumption (kg / kW.h), a singular parameter in the analysis of the economic feasibility of groups generating the diesel cycle. The specific consumption depends on the fuel consumption, which can be found through the mass or volumetric flow, and the electric power produced by the generator set. In the present work, a generator set of the brand YANMAR 4TNV88-GGE of nominal power of 21.6 kW consuming diesel oil S500, denominated of B0. The methodology used will be the simultaneous measurement of the fuel consumption using the (volumetric) and temperature-corrected volumetric (flowmeter and thermocouple), the purpose is to determine possible disparities in measurements, reflecting the achievement of specific consumption more efficiently. The experimental results obtained so far show that obtaining the specific consumption through mass flow is more efficient than the volumetric flow because the perturbations in the fuel line interfere directly in the calculation of the volumetric flow; the minimum temperature interference in the calculation of the mass flow was also another determining factor to characterize this method as the most effective.
