research REGARDING THE INFLUENCE OF ROUGHNESS ON PERFORMANCE OF AN INTERNAL COMBUSTION ENGINE
The present paper presents the study of the intake pipes surface roughness and its influences on the performance of an internal combustion engine. The measurements of the roughness were made experimentally, and the influences were studied using three simulation software: AVL BOOST (2013.1), GT Suite (7.4.0) and WAVE (2014.1). In order to obtain conclusive results, the same engine (Opel Astra F engine type C20NE) was simulated in three software, using the old type of materials for the intake pipes (forged cast iron) and the newer versions of materials (plastic). The data from all simulations were extracted, managed and accurately inspected and interpreted. The main conclusion of the paper is that the surface roughness of the intake pipe has an effect on the power of the internal combustion engine, not only because of the weight, but also the flow is improved. The same conclusion was obtained from all software.
