Vpliv geometrije plinske poti na zmogljivosti motorja z notranjim zgorevanjem

Zajec, Aleš (author), Katrašnik, Tomaž (mentor)

Zaključna naloga obravnava povečanje učinkovitosti enovaljnega štiritaktnega motorja z notranjim zgorevanjem s pomočjo izboljšanja plinske poti motorja. Opredeljeno je delovanje motorja, valovna dinamika in simulacijsko modeliranje sistema. Analiza plinske poti je bila izvedena na polnilnem in izpušnem sistemu na širšem območju delovanja motorja z namenom pridobitve optimalnejše rešitve. Simulacije so bile izvedene v profesionalnem simulacijskem programu. Simulacijski rezultati kažejo velik vpliv valovne dinamike sistema na učinkovitost motorja z notranjim zgorevanjem. Pri ustreznem dimenzioniranju plinske poti je mogoče izboljšati učinkovitost motorja z notranjim zgorevanjem in prilagoditi karakteristiko motorja za želeno uporabo.

• Title: Impact of gas path geometry on the performance of an internal combustion engine

Abstract

The thesis describes increasing efficiency of a Single-cylinder four-stroke internal combustion engine by improving the gas path of the engine. It identifies operation of the engine, wave actions and simulation modeling of the system. Analysis of the gas path was carried out on inlet and exhaust system on a wide operating range in order to obtain the best solution. Simulations were performed in professional simulation software. Simulation results show as great influence of the wave actions of the system on a efficiency of the internal combustion engine. With proper configuration of the gas path system, it is possible to improve efficiency of the internal combustion engine and adjust the engine characteristics for intended use.
