Analysis of Inlet and Outlet System of Racing Engine and Influence of Various Configurations on Brake Mean Effective Pressure

This article is focused on experimental analysis of acoustic wave influences on the brake mean effective pressure. An experimental base was created using a racing motorbike driven by piston combustion engine, which is equipped with a developed inlet pipe. The inlet air pressure value changed from the atmospheric level to the under-pressure level. This change is connected directly with increasing of the power output and torque. The tuned racing outlet system was applied for measuring of the outlet pipe characteristics. There were investigated influences of the individual configurations in the case of both analysed systems by means of the sequential experimental measurements. During measurement performed using the final configuration of the inlet system there was recorded an increment of the power output on high speed what is illustrated at comparison of global benefit relating to the basic version. The presented inlet pipe was successful in the motorsport area and it was patented, as well.
