EXPERIMENTAL INVESTIGATION AND BIODIESEL PREPARATION USING TRANSESTERIFICATION PROCESS AND PERFORMANCE CHARACTERISTICS ON A VARIABLE COMPRESSION ENGINE

Rapid increase in global population, demand for utilization of transportation is prevailing as one of the main concerns in releasing the dangerous exhaust gasses which causes harm to environment. Due to rapid usage of the fossil fuels like diesel fuel, there occurred scarcity and increase in pollution though the diesel gives better efficiency for transportation. An alternative looks up is necessary to mitigate the environmental pollution and increase the awareness by using vegetable oils as a potential alternative source. These vegetable oils are not directly suitable to use in existing engines since the kinematic viscosity is more. Hence by converting to biodiesel using transesterification process these biodiesel fuels are used in CI engine. In the present investigation an attempt to estimate the performance characteristics of variable compression engine using rice bran oil at various blend ratios RBrBD5, RBrBD10 RBrBD15, RBrBD20 were investigated as an alternative to mineral diesel fuel.
