DESIGN OF TURBOCHARGER FOR KTM 390RC

In order to increase energy efficiency of thevehicle powertrain, the innovative solutions in the construction of internal combustion engines, its aggregates, systems and equipment must be obtained. A trend that is prevalent today is widely known as downsizing. Namely, downsizing involves reducing of engine volume (consequently, its mass) and keeping or even increasing the power output compared to a reference IC engine in the same time. This trend of increasing energy efficiency is unthinkable without to use the supercharging systems. The most acceptable aspect supercharges the IC engines, in terms of energy efficiency is the use turbochargers that used exhaust gases which are producing in the combustion process in IC engines. Connecting turbochargers and IC engine is not feasible without knowing the turbochargers performance expressed in form of the compressor and turbine maps. Turbochargers performance testing is done on specialized development laboratories which are equipped with measuring elements necessary to simulate the working conditions prevailing in the real IC engines. Turbochargers testing methodology must be conducted in accordance with the recommendation
