Abstract

An optimized piston which is lighter and stronger is coated with zirconium for bio-fuel. The low grade LHR engines are using ceramic coatings on piston, liner and cylinder head, while medium grade LHR engines provide air gap in the piston and other components. It is necessary to test the coated piston for withstanding the stresses and strains. In this paper, the coated piston undergone a vonmisses test by using ANSYS for load applied on the top. Analysis of the stress distribution was done on various parts of the coated piston for finding the stresses due to the gas pressure and thermal variations. Vonmisses stress is increased by 16% and deflection is increased after optimization. But all the parameters are well with in design consideration.
