Abstract
Effects of ethanol blending on performance and emissions of a direct injection diesel engine equipped with common rail injection and cold EGR systems were investigated under various ethanol blending conditions. The results indicate that ethanol blending with high injection pressure offers smoke-free combustion under high engine loading. However, this gives an increase in combustion noise and NOx emissions. In such a condition, employing pilot injection and cold-EGR lowers the combustion noise and greatly improves the NOx-PM trade-off. Under low engine loading, usage of pilot injection with proper timing and amount improves combustion stability and lowers emissions of unburned species. The overall results indicate that maximum acceptable ethanol blending does not exceed 20%.
