Abstract

The invention of IC engine and subsequent development led to wide spread use of conventional lubricant along with fuel, which are being depleted at a rapid rate and leads to environmental pollution.But vegetable oil was restricted due to low thermo-oxidative stability and poor cold flow behaviour which was improved by chemical modification via esterification process. The aim of this paper was to formulate green lubricant which gives clean and better per-formance under working condition. From literature, it was suggested that bio-lubricant can be used as an alternative to synthetic lubricants after overcoming poor cold flow properties and oxidative stability. The objective of this re-search work was to overcome the above said problem. The green lubricant was formulated and compared with syn-thetic lubricants for their properties.Performance and emission tests of the same were performed using Kirloskar make two stroke petrol engine at constant speed of 3000rpm.Experimental results showed that brake thermal effi-ciency and mechanical efficiency of green engine oil were improved by 13% and 27% respectively for green engine oil. Also, volumetric efficiency of green engine oil is nearly same as that of MAK 2T engine oil. Emission of CO, CO2and HC were reduced to around 62%, 54% and 44% respectivelyin case of green engine oil compared to syn-thetic MAK 2T engine oil. Based on this study, green engine oil can be used as a substitute for synthetic MAK 2T engine oil. This work was tested for only two wheeler petrol engine along with fuel it can be extended for four stroke engine without mixing with petrol
