INFLUENCE OF NANO CERIUM OXIDE IN EMISSION REDUCTION WITH METHYL TERT-BUTYL ETHER - GASOLINE BLENDS AT HCCI ENGINE

Dadapeer Doddamani, Prakash Esamudra Sharanappa

Abstract


This article is focused to analyse the HCCI engine operated with blends of nano CeO2, Methyl tert- butyl ether (MTBE)-gasoline blends. The blending proportions of MTBE are 5vol%, 10vol%, 15vol% and 20vol%. For CeO2, it is 30ppm, 60ppm and 90ppm. The mixing is carried out with high shearing ultrasonication process. The optimal air-fuel ratio and chamber pressure were identified as 2.52 and 2.5 bar. From the experimentations, The Brake thermal Efficiency was found to be improved up to 3% with CeO2 + MTBE blends than pure gasoline, and the brake-specific fuel consumption was reduced up to 0.03 kg/kW hr compared with a conventional gasoline engine. The emission parameters such as NOx, CO and HC have been identified as relatively lower as 857ppm, 0.07vol% and 11ppm respectively with MTBE 15 + 90ppm than gasoline. The use of both MTBE and CeO2 nanoparticles are found better to improve the performance and reduce the emission further.
