This project aims to develop a prototype engine powered by biogas and dedicated for use in cargo vehicles. Its main initial stages are the study of alternatives for air and fuel supply and the design of a combustion chamber that promotes the efficient use of the fuel-air mixture, both from the point of view of energy conversion and from the point of view of reducing the production of pollutants. Using numerical simulation of combustion chambers as a tool in these studies, its results will be confronted with laboratory and field experiments of engine prototypes to validate the models produced. It is also planned to use an optical access AVL engine in the study of biomethane combustion and to carry out tests on a thermodynamic single-cylinder research engine to define the cylinder head and piston to be used in the prototype. After assembling and testing the prototype on a cylinder of a multicylinder engine, it is planned to carry out laboratory tests comparing performance and emissions with the engine running on biogas and on diesel oil. Next, an Electronic Management Unit will be developed, using the ETAS ASCET tool, for subsequent engine modeling and implementation of a Hardware in the loop for it, essential for greater flexibility in the calibration phase. Finally, the engine must be mounted on a vehicle to carry out field tests, also comparative with a vehicle equipped with an equivalent diesel engine, with PEMS- portable emissions measurement systems resources, following the guidelines of European directives. The project takes place in cooperation with the companies AVL SOUTH AMÉRICA LTDA, CAOA MONTADORA DE VEÍCULOS LTDA., ROBERT BOSCH LTDA. and the ICTs UFSM, UNB, IPT and USP, with each ICT having its associated coordinator.
