Abstract

The need to replace fossil fuels is now a priority in the world. The biodiesel from non-edible crops is a line of work to apply in agricultural communities fundamentally. In this work the use of mixtures of diesel-biodiesel of castor oil in a 7.46 kW generator set with a diesel engine was studied. The behavior of different mixtures of diesel-biodiesel and pure diesel was studied at different loads of the generator set and the fuel consumption was measured as a response variable. A multiple linear regression model in the statistical program SSP was used to process the data. A mathematical model with an adjustment R2, able to predict the consumption for different mixtures and at different loads was obtained. In field conditions, its energy performance can be determined from the variables studied and thus, determine the consumption required in each case.
