ABSTRACT
Biodiesel is considered as a viable alternative in regions where traditional diesel fuel is not readily available. In an effort to improve the diesel engine efficiency under these circumstances, combustion components were treated with a coating of partially stabilized zirconia with a 500 µm layer coating using plasma coating technology. In this study, the engine was powered by neat coconut waste cooking oil (CWCO) with diethyl ether (DEE) serving as an additive. A fuel mixture comprising 90% CWCO and 10% DEE was used to compare the performance of coated and uncoated engines to diesel fuel standards. Direct-injection compression ignition engine, tested with loads up to 12 kgf, showed lower BSFC and improved BTE despite lower NOx emissions. HC, CO, and smoke emissions were 18%, 11%, and 19% lower in blends in the 90% CWCO and 10% DEE than blends compared to diesel fuel at higher loads.
