and diesel fuels on combustion, performance and emission characteristics were
investigated and compared experimentally in a four stroke, single cylinder
direct injection diesel engine at different engine loads. For this reason the
test engine was operated with different engine loads including 3.75, 7.5,
11.25, 15 and 18.75 Nm at 2200 rpm engine speed. The variations of in-cylinder
pressure, heat release rate, cyclic variations, combustion duration and CO, CO <sub>2 </sub>,
NO <sub>x </sub> and soot emissions were determined. The test results showed that
in-cylinder pressure and heat release rate increased with B30 compared to
diesel for all engine loads due to better oxidation reactions. CO and soot
emissions reduced  by about 57.9 % and
25.5 % with biodiesel compared to diesel at 18.75 Nm. It was also found that
higher indicated mean effective pressure (imep) was obtained with B30 according
to neat diesel. Besides, shorter combustion duration was determined with B30. Combustion
and performance characteristics can be improved with biodiesel compared to
diesel. As a result, neutralized waste cooking oil biodiesel-diesel fuel
mixture (B30) could be easily used without engine modifications in diesel
engine. </span> </p> <p> </p>}, number={1}, publisher={Otomotiv Mühendisleri Derneği}
