Abstract

Biodiesel fuels are
among the leading renewable alternative fuels, available to implement on diesel
engines simply. Testing biodiesel fuels on engines, results similar to nominal
engine performance data are reported in the literature, since having chemical
properties very close to diesel fuel. Methyl/Ethyl esters (Biodiesel fuels), of
various oils extracted from vegetables or animals, are used by many researchers
on various types of engines and for various testing conditions. In the study,
effects of sunflower oil methyl esters on engine performance, heat release rate
and indicated engine parameters are investigated experimentally on a single
cylinder, DI Diesel engine. Tests are performed with diesel fuel and B50 blend
fuel, consisting of 50% diesel and 50% biodiesel, fuels at full load condition
and at different speeds. Engine brake torque, brake power, brake specific fuel
consumption, brake thermal efficiency, heat release rate, and indicated engine
parameters are calculated from test data, and the results obtained using diesel
fuel and B50 blend fuel are compared. Although some worsening on performance
data and heat release rate on B50 side, results are very close to each other.
