In the Internal Combustion (IC) engine, there are unburned hydrocarbons due to the improper combustion that takes places during exhaustion which leads to air pollution. These unburned hydrocarbons can be reduced by coating the different ceramic powders on the top of the piston. Here, an automotive piston is modeled and finite element analysis is done with different ceramic powders of 125 µm and 250 µm thicknesses. Different ceramic powders namely Alumina-Titania (60%-40%), Alumina, Titania, and Zirconia are coated on the piston. The coating is done on the piston by High-Velocity Oxygen Fuel (HVOF) technique. The experimental analysis is done on Kirloskar engine with uncoated aluminum piston and Zirconia coated aluminum piston with different loads. The experimental results such as exhaust gas temperature, mechanical efficiency and Carbon monoxide (CO) emissions for both the pistons are compared.
