Resumen
This paper presents the study for the sizing of the variable length intake manifold for the energy efficiency prototype of Universidade Tecnológica Federal do Paraná located in Pato Branco, focusing on increasing the volumetric and energy efficiency of the engine by harnessing the accumulated kinetic energy in the fluid present in the intake manifold after closing the in take valve. Through concepts discussed and selection of equations that best fit the engine, the theoretical sizing was performed through computational interactions generating collector length values that are compatible with the engine speed and the speed of the fluid to be admitted, ensuring that the length is compatible with the frequency of the wave moving through the collector. In addition to the sizing, improvements are presented for air flow, atomization of the mixture and simulations that present improvements regarding the operation of the collector. Bringing in the end the collector dimensioned in a way that guarantees efficiency gains to the motor.
