In order to use waste (BIOMASS), such as rice rind, we use a gasification process, which is a form of increasing the energetic use of Biomass. A fluidized bed gasifier at UNICAMP was used with an engine of 5.965 liters of total displacement and 6 cylinders, with compression ratio of 12:1 in the OTTO cycle and which is originally used in vehicles driven by compressed natural gas, to work with low heating power gas (4 to 6 MJ/Nm3) produced by the gasifier. The following values were obtained in the tests: Power ( kW) = 40.7 @ 1800 rpm, Feed (crankshaft degrees) = 30 Exhaust temperature (°C) = 596 Lambda = 1,12 Maximum Combustion Pressure (KPa) = 4000
