The biodiesel has lower volatility and is costlier than the fossil diesel. Hence it is necessary to add a low cost fuel which has higher volatility, with the diesel. The tire pyrolysis oil (TPO) produced from waste tire and tubes have these desirable properties and hence in this work, we have mixed TPO with biodiesel to enhance the properties of the biodiesel. The engine tests were carried out on a single cylinder compression ignition engine with the mixture of biodiesel and TPO as fuel. From the engine tests, it is observed that the fuel mixture results in engine performance close to diesel operation at the higher injector nozzle opening pressure.
