Based on the physicochemical features CME was used as fuel in a diesel engine test rig of matador vehicle without any modification to the engine system or fuel lines. The engine started and achieved maximum rpm and was stable across various acceleratory inputs without any unusual sound or missing. The engine stopped when the ignition was switched off. The functional test of CME provided a positive sign for using CME as a fuel for road trials in a new diesel vehicle (Table 1). The power and the torque of the vehicle using diesel as fuel are recorded as 16 bhp 3200 rpm and 38 Nm @ 2000 rpm. The successful part of any prospective biofuel is, whether an engine using the biofuel will perform similarly or better than an engine using normal gasoline based diesel. With respect to the similarity noticed in the functional feature of CME as a biofuel, the CME was used in a diesel engine of a new vehicle (TATA Ace Magic-diesel) for determining its technical feasibility The torque and the power of the engine were determined using CME as a fuel in the new vehicle. It was reported that, performance of any fuel can be judged by power and torque output that it can generate [30]. The test run was done on TATA Ace Magic-diesel vehicle on dynamometer for determining the power and torque as against the specifications of the manufacturer of the vehicle. The power and the torque of the CME as a 296
