In this work an analysis of the performance of a multi-fuel engine fuelled allowing for the concentration of alcohol in gasoline and the use of CNG. The engine used was a four cylinder, 1.242-L, multi-fuel engine in full load, respecting the air/fuel rate established by the manufactures in the engine original calibration. A CNG BRC 5th generation multi-point fuel injection system was installed in order to run with CNG. The calibration and adjustments were made using a development engine control unit for the different fuels. This work presents a comparison among the performance curves aiming to obtain the best relation among torque, power and specific fuel consumption for the various proposed configurations.
