About this Research Topic
Currently, the price of the alternative fuel options has not been competitive with cheap fossil fuels. Therefore, local and cost-effective fuels are needed in many regions around the world to decrease the share of fossil fuels and increase the self-sufficiency of energy generation. Independence from imported energy will be emphasized during the coming decades. Phenomena and properties related to alternative liquid fuel blends for different diesel engines are widely reviewed but the feasibility of all possible blend options must be studied separately. Therefore, specified research is still required. Properly managed fuel blending can be used to optimizing fuel to obtain certain beneficial properties while minimizing deleterious effect.
As the share of carbon neutral fuels need to be increased and at the same time the aim is to reduce the share of fossils, one feasible way to achieve the targets’ is to blend fuels. Blending new renewable fuels with conventional ones facilitates the technical transition period of the power production revolution before the 100% renewable or carbon neutral options are in wider use.
Fuel blending can either be in-cylinder blending, combining i.e. gaseous and liquid fuel components, or blending can be done before introducing the fuel into cylinder. When different alternative fuels are used as energy power source, several questions concerning their feasibility rises. I. e. which fuels options will mix together and are the alternative fuels compatible with existing fuel handling and storing facilities and engine parts.
The scientific research aims to fulfil the knowledge gaps related to feasibility issues.
This Research Topic collection concentrates in research papers about fuel blending in terms of the following issues:
• The realistic blend share, blend quality and properties;
• Blending different phases (gaseous+ liquid, liquid+liquid, gaseous+gaseous), using additives to stabilize the blend and also analyzing their effect on combustion and emissions;
• Demands for fuel storing and material compatibility, and issues related to suitable existing storing and utilization facilities as well as safety issues.
This Research Topic welcomes Research articles, Review articles, Mini Review and Perspectives.
Keywords: Fuel blending, internal combustion engine, alternative fuels, fuel stability, material compatibility
