Abstract
This work presents the experimental study and the performance analysis of a compression ignition internal combustion engine fueled with commercial Brazilian diesel oil and preheated straight soybean oil. The preheating was developed through two methods: electrical resistance and microwave irradiation. Tests on a dynamometric bench were carried out to compare the engine performance with the soybean oil preheated by both method s and the diesel oil asthe standard fuel. The engine was tested at different speeds and a load condition. The performance parameters obtained were indicated specific fuel consumption (ISFC) and indicated thermal efficiency. Emissions of unburned hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx) were also measured during the tests. Additionally, in-cylinder pressure was measured and used to obtain the heat release rate (HRR) from a zero-dimensional modeling of the combustion chamber. The HRR data with each fuel tested supplied information about the combustion process. The results showed differences in emissions, combustion and performance in the engine operation with preheated straight soybean oil by the two preheating methods.
