“…A MAHA 5 gas analyser recorded emissions such as CO, HC, CO 2 , O 2 and NO x . A sophisticated pressure transducer was used to record the cylinder pressure data and thereby calculate the heat release rate (HRR) and cumulative heat release rate (CHRR) using Equation (1) [23] and Equation (2) [24] as shown below:…”

In diesel engines, emission formation inside the combustion chamber is a complex phenomenon. The combustion events inside the chamber occur in microseconds, affecting the overall engine performance and emissions characteristics. This study opted for using computational fluid dynamics (CFD) to investigate the combustion patterns and how these events affect nitrogen oxide (NOx) emissions. In this study, a diesel engine model with a flat combustion chamber (FCC) was developed for the simulation. The simulation result of the heat release rate (HRR) and cylinder pressure was validated with the experimental test data (the engine test was conducted at 1500 rpm at full load conditions). The validated model and its respective boundary conditions were used to investigate the effect of modified combustion chamber profiles on NOx emissions. Modified chambers, such as a bathtub combustion chamber (BTCC) and a shallow depth chamber (SCC), were developed, and their combustion events were analysed with respect to the FCC. This study revealed that combustion events such as fuel distribution, unburnt mass fractions, temperature and turbulent zones directly impact NOx emissions. The modified chambers controlled the spread of combustion and provided better fuel distribution, improving engine performance and combustion rates. The SCC (63.2 bar) showed peak pressure rates compared to the FCC (63.02 bar) and BTCC (62.72 bar). This study concluded that the SCC showed better results than other chambers. This study further recommends conducting lean fuel mixture combustion with chamber modifications and optimising fuel spray, such as by adjusting the fuel injection profile, spray angle and injection timing, which has a better tendency to create complete combustion.

“…Biodiesel is biodegradable comes from renewable raw materials, uses energy more efficiently, can replace diesel fuel, suitable for sensitive environments and easy to use [26], can be used in diesel motors without any modification. Biodiesel is also able to reduce emissions [27]- [29] and does not add to the greenhouse effect that causes global warming [30], [31], because the carbon produced is still in the carbon cycle. Biodiesel even has a cleaning effect on fuel tanks, injectors and fuel hoses.…”

The energy sources used today are non-renewable energy. Non-renewable energy, if used continuously will experience scarcity. Therefore, renewable energy sources are needed as an alternative energy. One of alternative energy source is biodiesel. Biodiesel is an alternative fuel produced from vegetable or animal raw materials. The sustainability and diversity of biodiesel feedstock sources make it an attractive option for reducing dependence on fossil fuels. The problem is that all existing natural resources have not been utilized, the potential availability of raw materials and their production, lack of knowledge about the types of biodiesel and other types of biodiesel that can be developed. This article aims to review the different types of biodiesel that are being researched and developed and increasing knowledge and becoming a reference regarding the potential of natural resources and the opportunity to develop other types based on the potential of available natural resources. The research method used is a literature review study using the Publish or Perish 8 application, on the search menu Google Scholar is selected. Article search retrieved September 19, 2023. Based on this search, 14 articles were obtained that were in accordance with this research. The research results showed that the various types of biodiesel are bintaro oil, hazelnut oil, corn oil, crude palm oil, hydrotreated vegetable oil, kapok seed oil, rubber seed oil, used cooking oil, kesambi oil and graphene nanoplatelets. Each type of biodiesel has its own advantages, while the biodiesel feedstock that has the potential to be produced in large quantities is palm oil. This research also suggests that Indonesia's natural resource potential is very large, so we can also process and develop other types of biodiesel which can be used as alternative fuel.

“…So, it is essential to have research on the replacement of fossil fuels with biofuels that have lesser impacts on the environment [9,10]. Among all different biofuels, biodiesel has sparked much interest and fame among the various alternative fuel options [11,12]. Therefore, maximizing the development and utilization of biodiesel may be a potential solution to the current problem [13][14][15].…”

The biodiesel production process is extensively studied in the literature, focusing on mechanisms, modeling, and economic aspects, yet plant design and fluid flow losses remain underexplored areas. The study addressed this gap by designing a biodiesel production plant, analyzing flow losses, and developing a pipe network and suitable pump models. In this study, an integration of biodiesel production plant design and simulation of continuous production of Calophyllum inophyllum biodiesel was investigated. Biodiesel production encompasses complex stages that involve systematic planning and system design. The goal of the plant design is to reduce the losses that occur during the conversion process, which can reduce the capital cost of the plant. A few assumptions were made when selecting biodiesel plant materials, such as pipes, pumps, fittings, and bends. These assumptions were based on considerations of the biodiesel fluid properties and pressure requirements. On the other hand, Aspen Plus was used to simulate the biodiesel production process. Calophyllum inophyllum was considered oil as the biodiesel feedstock and was inputted to the Aspen Plus as triglyceride composition. The simulation was carried out with rigorous kinetic reactions using the Non-Random Two-Liquid (NRTL) method to predict the liquid equilibrium in the reactor. Results revealed that the designed steel pipe meets safety requirements with a bursting pressure of 49.68MPa, capable of withstanding the maximum pressure of 4 bar and turbulent flow conditions. Additionally, the selected pump satisfies the required head and flow rate, ensuring efficient fluid movement. Moreover, simulation results closely matched experimental data, and 88% of biodiesel yield was recorded.
