Evaluation of Engine Running with Gas of Low Power Heat Rate from of Biomass (Rice Husk) Produced by Gasifier

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
