Abstract
The paper presents an experimental study conducted with the support of the Laboratory of Internal Combustion Engines belonging to the Road Motor Vehicles specialization within “Politehnica” University of Timisoara, Engineering Faculty of Hunedoara. The purpose of this experiment is to test concepts of some devices conceived and made by the authors, awarded at numerous invention rooms, both inside the country and abroad. By the interposition of these devices on the intake route of internal combustion engines it is aimed to optimize the air intake process into the engine cylinders by two methods: 1 - increasing air pressure into cylinders by reducing pressure losses due to the air filter, and 2 - increasing the amount of air let into the cylinders by increasing its density due to lowering the temperature of the intake route. The experimental measurements have been made on different vehicles running in real traffic conditions, and on a stand holding a spark engine - and its afferent apparatuses – conceived by the authors. The experimental results have been processed and compared with the ones obtained during the operation without this devices.
Keywords Dynamic air transfer, pressure losses, internal combustion engine
