Effect of Biodiesel Blends on the Transient Performance of Compression Ignition Engines

Abstract

Prior to full electric conversion, internal combustion engines will still maintain a paramount position in heavy goods and earth-moving vehicles. The most promising, cleaner alternative to fossil fuels is biodiesel. While it does not require alterations in the engine design, hence no major overhaul of existing infrastructure, biodiesel is more sustainable and clean-burning than petro-diesel. Extensive research has been reported on the effect of biodiesel blends, on the operational characteristics of compression ignition (CI) engines as well as the emissions behaviour of such engines. The performance characteristics of CI engines under transient operational conditions with Biodiesel blends has had limited attention so far from researchers. In the present work, transient performance characteristics of a CI engine has been evaluated for various biodiesel blends and its effects on performance behaviour have been quantified. In addition, emission footprints of CI engines under various transient operational conditions have also been enumerated.

Study on combustion and emission characteristics of a micro‐rotary cam internal combustion engine

“…27 In order to select the best intake structure, the influence of different intake structures on the flow field, combustion and emission characteristics of small rotating internal combustion engine cylinders is compared and analyzed, and the optimal internal combustion engine intake structure is finally selected by analyzing and studying the internal combustion engine flow field, combustion and emission aspects. 28,29 As shown in Table 3, it is the specific parameters such as pressure and temperature of the intake air at different intake structures. The operating conditions of the small rotating internal combustion engine are set to: speed 3000 r/min, intake pressure 0.35 bar, equivalent ratio Φ = 0.8, The air-fuel ratio is 14.7.…”
