“…1−3 Biodiesels are renewable and degradable. 2,4 Lack of polycyclic aromatic hydrocarbons reduces Hydro carbons (HC) and Carbon monoxide (CO) concentrations in the exhaust. 5 In addition, the oxygen content of biodiesel plays an important role in reducing black carbon (BC) formation when local oxygen concentration decreases due to a diffusion combustion.…”

“…There have been a growing number of publications that study the correlation between fuel composition and engine emission, especially diesel particulate matter (DPM). 9,17,24 The relationship between biodiesel chemical properties and resulting emissions were investigated, 2,5,8,9,24,25 and it has been found that blends with higher oxygen content produce less PM but more volatile particles and increased levels of NO x ; 5,9,25 while biodiesel fuels with longer carbon chain length led to more PM. 8,24 DPM is well-known for its adverse effects on humans, animals and the environment.…”

We have studied the effect of chemical composition of biodiesel fuel on the physical (volatility) and chemical (reactive oxygenated species concentration) properties of nano particles emitted from a modern common-rail diesel engine. Particle emissions from the combustion of four biodiesels with controlled chemical compositions and different varying unsaturation degrees and carbon-chain lengths, together with a commercial diesel, were tested and compared in terms of volatility of particles and the amount of reactive oxygenated species carried by particles. Different blends of biodiesel and petro diesel were tested at several engine loads and speeds. We have observed that more saturated fuels with shorter carbon chain lengths result in lower particle mass but produce particles that are more volatile and also have higher levels of Reactive Oxygen Species. This highlights the importance of taking into account metrics that are relevant from the health effects point of view when assessing emissions from new fuel types.

“…Low viscosity will result in more complete combustion than high viscosity [17]; [18]; [19]. On the other hand, a low calorific value results in low fuel energy content so that the energy produced is low [18]; [20].…”

“…A decrease in the resulting power causes the resulting torque to decrease. In addition, increasing the ratio of the mixture causes the calorific value of the fuel to decrease so that the energy content decreases [20]. This affects increased fuel consumption.…”

“…Several things that can affect the result of a decrease in engine performance include the increasing viscosity of the fuel, which causes the combustion process to be less than perfect because the average diameter of the fuel droplet spray increases, bad atomization, so that the injection that occurs is inaccurate [17]; [18]; [19]. The same result is also conducted by [20], where the increasing percentage of biodiesel mixture causes a low calorific value so that the energy content of the fuel decreases, and hence the loss of power increases.…”

The Indonesian government is committed to increasing biodiesel usage as renewable energy by 23% of national energy consumption by 2025. Implementing the mandatory biodiesel program must be carried out sustainably to help reduce fossil energy consumption, reduce air pollution, and reduce the effect of greenhouse gases. The Ministry of Agriculture studied applying biodiesel from palm oil in agricultural machinery, especially four-wheeled tractors, to help implement agricultural mechanization in Indonesia. The research objective was to determine the effect of biodiesel on the performance of a four-wheeled tractor engine in several variations of the mixture to obtain the composition of biodiesel mixture that gave optimal engine performance. The experiment was conducted by testing the performance of a four-wheeled tractor engine on a laboratory scale referring to SNI 7146-2019, using biodiesel fuel with a mixture of B10 to B100 variations. The result showed that biodiesel affects the performance of a four-wheeled tractor engine. The efficiency of continuing engine power using biodiesel was the largest at B20 of 80.15% at the maximum governor and 80.97% at the standard PTO rotation of 540 rpm. The smallest power forwarding efficiency on the B100 was 76.12% at the maximum governor and 76.55% at 540 rpm PTO rotation. Biodiesel B20 provided the greatest maximum power of 23.55 kW, 44 kgf of torque, specific fuel consumption of 250.54 g/kW hours. At 540 rpm, PTO rotation produced a maximum power of 23.79 kW, 42 kgf of torque, the specific fuel consumption of 256.12 g/kW hours
