Abstract: This research article focused on partially stabilised zirconium nano-surface coating for piston head and cylinder head surface to perform the experimental investigation on direct-ethanol blend with 7.5 percent by mass of polyethene glycol (PEG7.5) fuel injection in the high compression ignition (EDICI) engine. NOx and soot emissions should be minimised while still increasing fuel economy. EDICI also removes NOx and soot, resulting in a low equivalence ratio and low flame temperatures. For starters, reaction rates are related to temperature and equivalence ratio. Injection, evaporation, and mixing processes are also involved in combustion. The pollution rating of the engine is used to investigate the engine's effect on emissions. The primary goal of this research article is to improve the engine's thermal efficiency. Just one-third of the energy in the fuel is converted into proper operation. This investigation was carried out in order to carry out this mission. As opposed to the uncoated engine, the coated engine's BTE (BTB) improves. Thermal conductivity is poor in the ceramic coating. Productivity increased as a result of the reduction in a wall surface. The variance of BTE is determined by thermal conductivity. BTE is 6.1 percent for 8YSZ + Al2O3 + TiO2
