【 摘 要 】

In this work, an experimental investigation has been carried on a single cylinder variable compression ratio CI engine to investigate its performance and emission characteristics using neat diesel and water emulsified diesel with 10% water content (WED10). The emulsion has been prepared in the laboratory using ultrasonic vibrator. The performance characteristics include brake thermal efficiency and BSFC, and the emission characteristics include NOx and HC emissions only. It is found that brake thermal efficiency undergoes no significant change for both the fuel variants and the BSFC is slightly reduced when only diesel is considered in the WED10. There is a considerable amount of reduction in NOx emission with the use of WED10. But HC emission increases with the use of WED10 due to decrease in combustion temperature and increase in ignition delay. Thus, WED10 may be considered as a viable alternate fuel having a greener emission and a comparable engine performance.
