Abstract:

The influence of thermal barrier coating on engine performance parameters, e.g., brake specific fuel consumption (BSFC) and Brake thermal efficiency, and exhaust gas temperature for neat diesel and Honge blend B20 was studied. With neat diesel, a 5% decrease in BSFC at lower loads and ∼ 9% decrease in BSFC at higher loads were observed for ceramic coated engine when compared to standard engine. With Honge B20 blend, a 0.5% decrease in BSFC at lower loads and ∼ 2.5% decrease in BSFC at higher loads were observed for ceramic coated engine compared to standard engine. BSFC was high for Honge 620 blend for both coated engine and standard engine, which can be attributed to lower calorific value of biodiesel compared to that of unblended diesel.An increase in brake thermal efficiency with biodiesel was less in both coated and standard engines compared to neat diesel. With biodiesel blend, there was an increase of exhaust gas temperature in coated engine to an extent of 15° to 5°C. Exhaust gas temperature with biodiesel in both coated and standard engine was lesser compared to neat diesel.
