Finally, there is the already commented omission of oxygen generation requirements. It is the author's opinion that this work covers...

...Jessica B. Baker; Ramees K. Rahman; Michael Pierro; Jacklyn Higgs; Justin Urso; Cory Kinney; Subith Vasu In recent years, hydrogen-carrying compounds have accrued interest as an alternative to traditional fossil fuels due to their function as zero-emission fuels. As such, there is interest...

...Achinta Sarkar; Ujjwal K. Saha The key challenge of dual fuel mode (DFM) of a compression ignition (CI) diesel engine is to improve the engine performance, and to reduce primarily the carbon monoxide (CO) and unburnt hydrocarbon (HC) emissions. The gaining popularity of DFM lies with its inherent...

In this study, a heavy-duty diesel engine effects on performance, combustion, and emission characteristics by spraying natural gas from the intake port and transforming it into a spark-ignition engine were investigated through 3D...

... and power (CHP) system with an electrical power output of 3 kW. The combustor is studied in an optically accessible atmospheric test rig, as well as integrated into the MGT system. This paper focuses on the influence of the admixture of CO 2 to natural gas on the NO x and CO emissions. Furthermore...

...Congbo Yin; Quanwei Chen; Zhendong Zhang; Haibing Zhu; Kai Shen The application of exhaust gas recirculation (EGR) technology on gasoline direct injection (GDI) engines can suppress knocking, reduce fuel consumption, and reduce NO x emissions. The effects of EGR with enhanced intake tumble flow...

...%, and BSFC rise of 9% were obtained by adding nitromethane and methanol in small fractions to gasoline. Combustion analysis was carried out using the cylinder pressure trace. High heat release rate and shorter combustion duration with nitromethane addition were observed. Emission measurements showed decrease...
