Heat release analysis of combustion in heavy-duty turbocharged diesel engine operating on blends of diesel fuel with cottonseed or sunflower oils and their bio-diesel

► Heat release analysis of combustion and emissions in heavy-duty diesel engine. ► Fueling with diesel fuel blends of cottonseed or sunflower oils and bio-diesels. ► Maximum cylinder pressures reduced with bio-fuels blends compared to neat diesel. ► Max. cylinder temperatures reduced with bio-fuels blends compared to neat diesel. ► Reduction of smoke and slight increase of NOx with bio-fuels blends.
