Compatibility of a Diesel Engine for Jatropha and Tamarind Seed Oil Mixed Biofuel and its Impact on Environment

Experimental investigation runs by a diesel engine fuelled by jatropha with Tamarind Seed Oil Methylester (TSOME) mixed biodiesel. The biodiesel (B10) contains 5% of jatropha, 5% tamarind seed oil, and the remaining 90% of diesel by volume. Here, noted higher Brake Thermal Efficiency (BTE) for biofuel than neat diesel by the effect enhanced combustion rate. Further, change the standard compression ratio (CR) of 17.5 to 19.5 and 21. However, higher BTE reported at CR21, followed by lower CR conditions. CO emissions showed lower for the compression ratio 21 than the other CR conditions and higher for the diesel. But, it emits higher CO2and HC emissions for the CR 21 and lower for the diesel.
