“…Furthermore, the emissions such as carbon monoxide (CO), hydrocarbon (HC) and carbon dioxide (CO 2 ) from a diesel engine is much lesser compared to the gasoline engine emissions. However, diesel engine remains to be an important source of pollution as their usage leads to release of nitrogen oxides (NOx), black smoke, particulate matter (PM) and sulfur oxides (SOx) that are detrimental to both environment and human health [2]. In fact, the emissions regardless of other parameters as including several parameters tend to make the analysis complex and increases the computational time consumption.…”

Generally, the compression ignition (CI) engine that runs with emulsified biofuel (EB) or higher viscosity fuel experiences inferior performance and a higher emission compared to petro diesel engines. The modification is necessary to standard engine level in order to realize its application. This paper proposes a guide vane design (GVD), which needs to be installed in the intake manifold, is incorporated with shallow depth re-entrance combustion chamber (SCC) pistons. This will organize and develop proper in-cylinder airflow to promote better diffusion, evaporation and combustion processes. The model of GVD and SCC piston was designed using SolidWorks 2017; while ANSYS Fluent version 15 was utilized to run a 3D analysis of the cold flow IC engine. In this research, seven designs of GVD with the number of vanes varied from two to eight vanes (V2–V8) are used. The four-vane model (V4) has shown an excellent turbulent flow as well as swirl, tumble and cross tumble ratios in the fuel-injected region compared to other designs. This is indispensable to break up heavier fuel molecules of EB to mix with the air that will eventually improve engine performance.

Introducing synthetic fuels and biofuels like biodiesel can be pivotal in transitioning to a decarbonised energy system. Biodiesel offers a versatile solution with various production technologies, each with advantages and disadvantages, depending on several factors, including the specific application of biodiesel. In a smart grid, an advanced electrical grid that leverages digital technology to detect and respond to local changes in usage, a small community could harness biodiesel for energy storage and supply. By implementing a renewable energy storage system in the form of biodiesel from waste oils, individuals can contribute to developing innovative solutions for the combined and distributed production of electricity and heat, primarily from renewable sources. The aim is to make the production-demand distribution networks within a hybrid system smart and in line with the concept of nanogrid. This localised grid can operate independently or in conjunction with the traditional power grid and can integrate generation systems from fossil and renewable sources, micro-cogeneration, and accumulation. The possibility of exploiting biodiesel in a nanogrid as an eco-sustainable source for energy storage opens up the possibility of building small-scale plants. For example, converting 3682 L/year of waste oils from a university campus dining facilities to 3712 L/year of biodiesel allows replacing 19% of the fossil diesel consumed by the university fleet, with a payback period of 16 months, lower capital and operational costs, and reduced greenhouse gas emissions of 9.37 tonnes CO2-eq/yr. Therefore, biodiesel becomes a sustainable energy source for energy communities, underscoring the innovative potential of this approach.
