    The effects of apricots seed oil biodiesel with some additives on performance and emissions of a diesel engine
    (International Journal of Automotive Engineering and Technologies, 2016) Aydın, Hüseyin; Hanbey, Hazar; Uyar, Mahmut; Şap, Emine
    The purpose of this experimental work is to investigate influences of using manganese (Mn) as a combustion catalysts on apricot seed oil based biodiesel production and its engine out parameters. The metal based additive (Mn) was added to biodiesel (B50) at different dosages of 20-40-60 μmol/L. Also, other additives the propylene glycol and dodecanol were added into apricot seed oil biodiesel (B50) at rates of 5% and 1%, respectively for preparing test fuels.This additives improved flash point, pour point and viscosity of the biodiesel (B50) fuel. Experiments were carried out to clarify the effects of all additives added to biodiesel on performance and emission characteristics of a three-cylinder DI diesel engine operated at a constant speed of 1500 rpm and different loads from 2,50 to 10 kW. The engine test results revealed that specific fuel consumption, NOx were not changed significantly with the adding additives to biodiesel (B50) fuel, while CO, HC and smoke emission profiles were improved.

    Performance and emission evaluation of a CI engine fueled with preheated raw rapeseed oil (RRO)–diesel blends
    (Journals & Books, 2010-03) Aydın, Hüseyin; Hanbey, Hazar
    Many studies are still being carried out to find out surplus information about how vegetable based oils can efficiently be used in compression ignition engines. Raw rapeseed oil (RRO) was used as blended with diesel fuel (DF) by 50% oil–50% diesel fuel in volume (O50) also as blended with diesel fuel by 20% oil–80% diesel fuel in volume (O20). The test fuels were used in a single cylinder, four stroke, naturally aspirated, direct injection compression ignition engine. The effects of fuel preheating to 100 °C on the engine performance and emission characteristics of a CI engine fueled with rapeseed oil diesel blends were clarified. Results showed that preheating of RRO was lowered RRO’s viscosity and provided smooth fuel flow Heating is necessary for smooth flow and to avoid fuel filter clogging. It can be achieved by heating RRO to 100 °C. It can also be concluded that preheating of the fuel have some positive effects on engine performance and emissions when operating with vegetable oil.

    Usage of methyl ester produced from waste grape and Mn additive as alternative diesel fuel
    (Petru Maior” University of Tîrgu Mureş, 2017-01) Aydın, Hüseyin; Hanbey, Hazar; Uyar, Mahmut; Sap, Emine
    In this study, methyl ester was produced from waste grape pulp sources. The produced methyl ester was mixed with diesel in different proportions, and was tested for engine performance and emission. It was found that with increasing biodiesel content, the specific fuel consumption and exhaust temperature have increased partially, while the CO, HC and smoke emissions decreased significantly. Additionally, in the scope of this study, dodecanol, propylene glycol and Mn based additives were added to fuel B50 to improve the emission and engine performance values. With the presence of additives, an increase in the exhaust temperature was observed, while a decrease in the specific fuel consumption, CO, HC, and smoke emissions were detected
