Their most significant contributions involve the experimental analysis of biodiesels and their effects on diesel engines. Key themes in their research include:
: Investigating the production of biodiesels from various agricultural sources, such as corn oil and rapeseed oil . They have conducted comparative studies on catalysts like sodium hydroxide ( NaOHcap N a cap O cap H ) and potassium hydroxide ( KOHcap K cap O cap H Ali Dogan Gulum Gulum
Ali Doğan and Gülüm Gülüm frequently collaborate with other Turkish engineers, such as A. Bilgin and A. Çakmak. Their findings are often published in journals focused on engineering and energy, including the Journal of the Faculty of Engineering and Architecture of Gazi University and various international research platforms like ResearchGate. Technical Impact Bilgin and A
: They have explored treating diesel-biodiesel blends with alcohols (such as C4 and C5 alcohols) to enhance engine performance and further lower exhaust emissions. Notable Publications and Collaborations carbon monoxide (CO)
: A critical part of their work involves quantifying tailpipe emissions—specifically hydrocarbons (HC) , carbon monoxide (CO) , and nitrogen oxides (NOx) —when using biodiesel blends. This research aims to reduce the environmental footprint of traditional diesel engines.
