Abstract: The exhaust gas from an internal combustion engine contains approximately 30% of the thermal energy of combustion. Waste heatrecovery systems aim to reclaim a proportion of this energy in a bottoming thermodynamic cycle ...

Abstract: A wave rotor is a shock-driven pressure exchange device that, while relatively rarely studied or indeed, employed, offers significant potential efficiency gains in a variety of applications including refrigeration and gas ...

Abstract: Most boosting systems in internal combustion engines utilize “pulse turbochargingâ€‌ to maximize the energy extraction by the turbine. An internal combustion engine with more than four cylinders has a significant overlap ...

Abstract: In our previous paper, a new gas exchange concept termed divided exhaust period regulated twostage (DEP R2S) system has been proposed. In this system, two exhaust valves in each cylinder are separately functioned with one ...

Abstract: Approximately 30% of the energy from an internal combustion engine is rejected as heat in the exhaust gases. An inverted Brayton cycle (IBC) is one potential means of recovering some of this energy. When a fuel is burnt, ...

Abstract: Exhaust gases from an internal combustion engine (ICE) contain approximately 30% of the total energy released from combustion of the fuel. In order to improve fuel economy and reduce emissions, there are a number of ...

Abstract: Turbochargers are a vital component for aiding engine manufacturers in meeting the latest emissions standards. However, their range of operation is limited for low mass flows by compressor surge. Operation in surge results ...
