Abstract: Abstract This paper reports the role and impact of nanoparticles contingent on emulsified cottonseed biodiesel. The Nano-emulsified biodiesel was made with Aluminum oxide (Al2O3) and Titanium dioxide (TiO2). The amalgamation of 90% blend 20 (B20) with 10% water has been considered as the base of Nano-emulsified biodiesel called B20W10. Here, four different combinations, such as 100 ppm of Al2O3 and TiO2 and 200 ppm of Al2O3 and TiO2 are used for the preparation of cotton seed Nano emulsified biodiesel fuel samples. The current diesel engine parts such as cylinder liner, piston top, and inlet, exhaust valve have been coated with fly ash material with a thickness of 200 µm to convert conventional engine into a low heat rejection (LHR) engine. Furthermore, an experimental investigation was carried out on the LHR diesel engine with neat diesel and prepared fuel samples at various loads. From that investigation noticed the maximum Brake Thermal Efficiency (BTE) for B20W10Al200 at maximum load, is around 13.79% higher than the neat diesel operation. And also observed the drastic reduction of HC, CO, and NOX and emissions for B20W10Al200 it is 55.35%, 33.03%, and 16.06% lower than the diesel operation at maximum load. Surprisingly, it has been noticed that the interaction of Nanoparticles with Nano-emulsified biodiesel has a quite prominent impact on the fuel in the LHR engine.
