Internal Combustion Engines are known for their unique sound characteristics. Through these characteristics, an experienced car mechanic will be able to diagnose the type of engine damage just by listening sound. This reduces need disassemble components pinpoint machine faults which also contributes a significant reduction in overall repair time. The main aim this paper is build process identif...

Combustion and evaporation processes occurring in a closed chamber can result in significant pressure rise and direct work transfer. The pressure and volumetric changes that accompany such processes allow substantial work potential to be achieved in cyclic nonsteady devices, such as internal combustion engines and pulsed combustion or detonation engines. The ideal pressure gain or work producti...
