In this study, the effects of tert-butanol on the engine performance of Karanja biodiesel/tert-butanol blends were examined. Experiments were conducted on a single-cylinder, four-stroke, wa...

The decline in the availability of fossil fuel, increase in cost and the stringent emission norms are the main concerns identified in the automotive sector during the recent years. Biodiesel is one of the hopeful alternate resources for the mineral diesel to address the above-listed problems. In the present investigation, waste chicken fat biodiesel has been prepared and used to investigate the performance features of single cylinder naturally aspired direct injection diesel engine. The waste chicken fat biodiesel is prepared using transesterification process, and the yield is found to be 94.8%. The physicochemical characteristics of the waste chicken fat methyl ester have been tested and found in line with ASTM standards. The blends of waste chicken fat biodiesel with mineral diesel have been prepared and experimented in a single cylinder standard compression ignition diesel engine without any modifications. The combustion, performance and emission characteristics have been studied, and it is found that the blend B20 resulted in higher performance and lesser emissions among the other test fuels.

Diesel engines are the major contributors of various types of air polluting gases like carbon monoxide, oxides of nitrogen, smoke, etc. Improvement of fuel properties is essential for suppression of Diesel pollutant emissions along with the optimization of design factors and after treatment equipment. Studies conducted in the past have shown that a significant reduction were obtained in the emissions using oxygenates. This paper investigates the performance and emission characteristics of a direct injection Diesel engine fueled with 2 Ethoxy Ethyl Acetate (EEA) blends. Different fuel blends which contain 5%, 10% and 15% of EEA were prepared and the effect of these blends on performance and emissions were studied on a single cylinder direct injection Diesel engine. The blends were tested under different load conditions and the result showed that EEA blended fuels improves the performance of the engine and reduce the emission level significantly.
