Investigation of Performance and Emission Characteristics of VCR Engine by Using Ceramic Coating on the Piston Crown with Using Methanol Fuel

Abstract:

The world faces the energy demand, exaggerated crude rates and reduce of fuel resources. Methanol has been considered as an alternate fuel. . The current study takes out an experiment of using methanol in VCR engine. They are blended with diesel at various mixing ratios. The results of methyl alcohol works in engine were checked in an exceedingly single cylinder, direct injection, water cooled and high speed VCR internal combustion engine at varied engine load with constant engine speed of 1500rpm conjointly we tend to mistreatment the limit coated piston with MgO-ZrO2 and Al2O3-13%TiO2 to investigation on performance and emission characteristics. The limit coating materials has low thermal conduction, low thermal expansion and high young’s modules. The influences of blends on CO, CO₂, HC, NO_X were investigated by emission tests. The brake thermal efficiency of mix M20 was found on top of diesel. The emissions of smoke, hydro carbon and chemical element oxides of methyl alcohol blends were on top of that of diesel. However the CO₂ emission is higher once we compare with diesel.
