A review of water injection applied on the internal combustion engine
Sipeng Zhu,Sipeng Zhu,Bo Hu,Sam Akehurst,Colin Copeland,Andrew Lewis,Hao Yuan,Ian Kennedy,Johan Bernards,Ciaran Branney +9 more
TL;DR: A comprehensive review of water injection applied on the internal combustion engine can be found in this article, where a detailed description of water evaporation processes is given. And the authors discuss the mechanisms of the in-cylinder combustion process with water addition with respect to the heat release rate, knock tendency and emission formations.

Research and application of over-expansion cycle (Atkinson and Miller) engines – A review
TL;DR: An over-expansion cycle (Atkinson or Miller) engine is the most suitable for hybrid vehicles because it can realize a larger expansion ratio and thus, a higher thermal efficiency while maintaining a normal effective compression ratio to avoid the knock.

Control of backfire and NOx emission reduction in a hydrogen fueled multi-cylinder spark ignition engine using cooled EGR and water injection strategies
Vipin Dhyani,K.A. Subramanian +1 more
TL;DR: In this paper, an experimental study was carried out on a constant speed multi-cylinder spark ignition engine fueled with hydrogen, where exhaust gas recirculation (EGR) and water injection techniques were adopted to control combustion anomalies (backfire and knocking) and reduce NOx emission at source level.

Experimental investigation on the knocking combustion characteristics of n-butanol gasoline blends in a DISI engine
TL;DR: In this article, the results of n-butanol and Bu20 were evaluated in a direct-injection spark ignition (DISI) single-cylinder engine with three throttle openings with stoichiometric air-fuel ratio.
Journal ArticleDOI
Effect of water injection on the knock, combustion, and emissions of a direct injection gasoline engine
Aqian Li,Zhaolei Zheng,Tao Peng +2 more
TL;DR: In this article, a numerical simulation method was used to study the feasibility of in-cylinder direct water injection technology to weaken the knock tendency of a turbocharged direct injection gasoline (GDI) engine and improve its combustion emission performance.

Internal Combustion Engine (ICE) bottoming with Organic Rankine Cycles (ORCs)
Iacopo Vaja,Agostino Gambarotta +1 more
TL;DR: In this article, a specific thermodynamic analysis in order to efficiently match a vapour cycle to that of a stationary Internal Combustion Engine (ICE) is presented. But the analysis is limited to the case of a single-cylinder engine.
