dc.description.abstractDue to the increasing energy supply and limited availability of fossil fuels, which rank first in energy supply, price fluctuations, and the release of pollutant emissions as a result of combustion, researchers are conducting research on more environmentally and friendly fuels that can be produced from renewable energy resources, have a lower C/H ratio. In this study, the use of 3 different fuel types (biodiesel, biodiesel-H2 and biodieselethanol-H2) in a 4-stroke, 4-cylinder diesel engine at a constant 1750 rpm engine speed and different engine loads (from 40 Nm to 100 Nm increase by 20 Nm engine load) impacts on diesel engine characteristics in terms of performance, combustion and exhaust emission characteristics were examined. It was determined that BSFC decreases by more than 20% with increasing engine load. In addition to this, maximum BSFC was seen in as 373 g/kWh in BD70E30 fuel. Increase in engine load, also led rise in cylinder gas pressure from 80 bar to more than 125 bar. It was shown that blended fuels improve cylinder gas pressure and control the maximum pressure rise rate by reducing ignition delay under certain test conditions. Compared to biodiesel fuel, blended fuels were seen to significantly reduce HC and CO2 emissions but slightly increase NO emissions. For all fuel types maximum NO emission was obtained at 100 Nm as 29.6 g/kWh, 31.4 g/kWh and 30.7 g/kWh, respectively BD100, BD100+H2 and BD70E30+H2.
