“…Its relatively higher viscosities compared to petrol diesel by a factor of about 11-17 means will cause a number of problems in fuel pumping, combustion and atomisation [7]. The coking of fuel injectors is also another common problem [8]. Moreover, in an unmodified diesel engine, excessive engine wear may occur with the use of biodiesel [9].…”

Indonesia and Malaysia are currently holding prominent roles in the global palm oil market. Both countries are the top two palm oil producers in the world and have ambitious targets to increase the palm oil-based biodiesel mandate. In Indonesia, the current programme of blending 20 per cent palm oil into 80 per cent diesel (B20) increases to B30 in 2020. Likewise, Malaysia plans to increase its biodiesel mandate from B10 to B20 in 2020. However, the outbreak of COVID-19 has infected millions and brought the global economy to a near-deadlock. The effect is particularly severe in the fuel industry owing to movement restrictions and the historic drop in oil prices. Evaluating the impact of the COVID-19 on the biodiesel industry is crucial for policymakers but challenging as the pandemic has evolved with intense speed. This article aims to discuss the impact of COVID-19 on the Indonesian and Malaysian biodiesel industry. In addition to that, a number of possible solutions to overcome the challenges were addressed and proposed. Despite severely affected by COVID-19, both Indonesia and Malaysia can use this momentum to improve and strengthen their biodiesel sector. Given its fiscal deficit, Indonesia should postpone its biodiesel blending mandate as the subsidy to support the programme can worsen the country’s financial stability. In Malaysia, where labour shortage is prevalent, modernising plantations with automated equipment, for instance, could potentially remove the dirty and dangerous stereotypes associated with plantation works, thus attracting more locals to work in the palm oil plantation and solving the labour shortage. This paper also briefly addresses the adoption of Industry 4.0 and Circular Economy for the palm oil biodiesel industry.

“…The cold filter plugging point (CFPP) and cold point (CP) of passenger car/light-duty truck B5, B10, and B20, as the indexes of CFPs, affect the startability and driveability of the vehicles . The use of engine under CP and pour point (PP) of Pongamia biodiesel/waste cooking oil biodiesel led to starting problems …”

“…8 The use of engine under CP and pour point (PP) of Pongamia biodiesel/waste cooking oil biodiesel led to starting problems. 9 Many studies have been carried out to find out the factors that have an impact on and the methods that pose improvement to biodiesel CFPs. However, the problems derived from CFPs are still not optimistic.…”

Biodiesel is a mixture of fatty acid alkyl esters (FAAEs) produced by transesterification, which has been promoted as a substitute for petroleum diesel in some areas of China. However, it shows poor cold flow properties (CFPs), such as high pour point, high cloud point, and high cold filter plugging point, meaning that biodiesel would crystallize under low-temperature conditions, thus resulting in engine problems and emission issues. This review focused on the mechanisms related to the CFPs of biodiesel and outlined the factors that initialize and accelerate the crystallization process. The influence of CFPs on engine performance and pollutant emissions was also discussed. Particular emphasis was given to available methods that can improve the CFPs of biodiesel. Modifying the composition of FAAEs, changing the component ratio, and removing minor constituents are three primary directions. Every derivative method was described in detail about the characteristics, shortcomings, and what can be improved. The type and load of cloud point/pour point/cold filter plugging point cold flow improvers were compared and selected on the basis of the improvement effect of CFPs. Microemulsion is a new method that may be used to improve the CFPs of biodiesel. As a result of the variability of the biodiesel components and the complexity of each improving method on the overall fuel properties and performance, the CFP modification methods should be studied and evaluated carefully and comprehensively before being adopted in industrial applications.

“…Applying biodiesel blends as a diesel engine fuel has been reported to have benefits, especially in engine emissions. Biodiesel blends generally exhibit comparable engine performance in terms of brake thermal efficiency (BTE) and brake power when compared to pure diesel [5,6]. Substantial reductions in harmful emissions such as carbon monoxide (CO), carbon dioxide (CO 2 ), unburned hydrocarbon (HC), and particulate matter (PM) were found in engines fueled with biodiesel blends [7].…”

Performance, Emissions, Combustion and Vibration Analysis of a CI Engine Fueled with Coconut and Used Palm Cooking Oil Methyl Ester

et al. 2020

Biodiesels from coconut and palm cooking oil are viable alternatives to diesel fuel due to their environmental sustainability and similar physicochemical properties compared to diesel. In the present study, these fuels were tested separately in a diesel engine by blending with fossil diesel in proportions of 10%, 20%, 30% and 40% by volume. Experiments were conducted under a constant brake mean effective pressure (BMEP) of 400 kPa and at 2000 rpm. The results revealed similarities in engine performance, emissions, combustion and engine block vibration for used palm cooking oil methyl ester (UPME) fuel blends and coconut methyl ester (CME) fuel blends. Most blends resulted in slight improvements in brake specific energy consumption (BSEC) and brake thermal efficiency (BTE). A maximum reduction of 54%, 89% and 16.8% in pollutant emissions of brake specific hydrocarbons (BSHC), brake specific carbon monoxide (BSCO) and brake specific nitrogen oxides (BSNOx), respectively, was observed with UPME and CME in the blends. The cylinder pressure profiles when UPME-diesel and CME-diesel blends were used were comparable to a standard diesel pressure trace, however, some deviations in peak pressure were also noticed. It was also apparent from the results that engine vibration was influenced by the type of methyl ester used and its blend composition. Notably, the rate of pressure increase was maintained within an acceptable limit when the engine was fueled with both of the methyl ester blends.
