With the population explosion, demand for energy has increased exponentially. Diesel engine is one such prime mover which can meet the demand. Diesel engines have high efficiency, but, releases large quantity of harmful exhaust emissions. In this regard, present experimental investigation, performance and emission characteristics of redesigned swirl chamber (RSC) of indirect injection diesel engines were studied. Exhaust gas recirculation (EGR) is one of the methods which can be effectively utilized to curb the NOx emissions. The result shows brake thermal efficiency of 10%, 14% and 17% of EGR using the RSC are 3.18%, 4.21% and 6.19% lesser. Brake specific fuel consumption of 10% EGR, 14%EGR, 17%EGR with RSC are 3.56%, 8.38% and 12.95% higher compared to 0%EGR. NOx emissions for 0%EGR, 10% EGR, 14%EGR, 17% EGR are 9.47%, 18.41%, 6.98% and 1.67% respectively less at 75% load with RSC. From the performance and emission characteristics 10% EGR may be recommended as an effectual tool to curb NOx emission. [ABSTRACT FROM AUTHOR] |
