Abstract

This investigation is focused on the study of the overall performance of a single-cylinder diesel engine with the use of 99.99 % pure elemental hydrogen (H₂), as a gaseous fuel and algae Spirogyra biodiesel 30 % (SBD30) with 1.5 % Di-tert Butyl Peroxide (1.5%DTBP) as cetane improver and 2 % Algae Residual Carbon Nanoparticle (2%ARCNP). During the investigation, the hydrogen flow rate was controlled by an electronic gas injector and varied in the range of 5–20 lpm in the increment of 5 lpm. Among the fuel blends SBD30 + 1.5%DTBP+2%ARCNP+15H₂ acted as a good combination to reduce ID and CD; and to boost HRR, BTE, and EGT. Additionally, this resulted in a drastic decline in the emission components such as HC, CO, and smoke. However, a surge in NO was observed for all the fuel sampled by the induction of H₂. For SBD30 + 1.5%DTBP+2%ARCNP+15H₂ a shorter ID and CD were observed at 7.2°CA and 34.5 °CA than diesel respectively at full load. The MCP for SBD30 + 1.5%DTBP+2%ARCNP+15H₂ was 81 bar which occurred at 9.2°CA, however, the HRR was 61.3 J/°CA which was 1.2 % lower than that of 20 LPM hydrogen flow rate, at full load respectively. By using hydrogen + DTBP + ARCNP, the BSFC was overall lower by about 22 % and the BTE was improved by about 36.1 %. The CO, HC, and smoke for SBD30 + 1.5%DTBP+2%ARCNP+15H₂ was 64.8 %, 38.8 %, and 29.2 % lower than diesel however, the NO emission was 32.6 % higher than diesel at full load respectively.

双燃料燃烧模式下氢气与水藻、生物柴油和燃料添加剂在柴油机上的暴露作用

本研究主要研究了使用99.99%纯单质氢（H2）作为气体燃料和30%藻类Spirogyra生物柴油（SBD30）， 1.5%过氧化二叔丁基（1.5%DTBP）作为十六烷改进剂和2%藻类残余碳纳米颗粒（2%ARCNP）的单缸柴油发动机的整体性能。在调查过程中，氢气流速由电子气体喷射器控制，在5 lpm的增量范围内变化在5 - 20 lpm之间。其中，SBD30 + 1.5%DTBP+2%ARCNP+15H2是降低内燃和CD的较好组合；并提高HRR， BTE和EGT。此外，这还导致了HC、CO和烟雾等排放成分的急剧下降。然而，通过诱导H2取样的所有燃料中都观察到NO的激增。对于SBD30 + 1.5%DTBP+2%ARCNP+15H2，在7.2°CA和34.5°CA下的ID和CD分别比柴油短。SBD30 + 1.5%DTBP+2%ARCNP+15H2在9.2°CA条件下的MCP为81 bar， HRR为61.3 J/°CA，比20 LPM氢气流量条件下的HRR低1.2%。使用氢+ DTBP + ARCNP， BSFC总体降低了约22%，BTE提高了约36.1%。SBD30 + 1.5%DTBP+2%ARCNP+15H2在满负荷工况下CO、HC和smoke分别比柴油低64.8%、38.8%和29.2%，而NO排放量比柴油高32.6%。

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
