Abstract

The present study is an experimental study that investigates the performance and emission characteristics of a variable compression ratio (VCR) diesel engine when the engine is fuelled with diesel, biodiesel, and small amount of alcohol blended fuels. The experimental study was evaluated with a single cylinder, water cooled, multi fuel VCR diesel test engine. The experimental results showed that increasing compression ratio improves performance characteristics such as brake thermal efficiency and specific fuel consumption of the test engine for all test fuels. However, increasing compression ratio caused to increase of NOx and CO2 emissions. Blending alcohol with diesel fuel showed a slight decrement in the means of brake thermal efficiency and thus elevated specific fuel consumption values. The maximum increment of specific fuel consumption was measured as 0,34% for diesel-alcohol blends. But, blending alcohols with biodiesel fuel improved performance characteristics of the engine compared to diesel fuel up to 2,65%. Blending biodiesel with alcohols showed improvement in the means of NOx emissions up to 6,01%.
