“…The differences in the calorific value will affect the combustion process that occurs and the energy produced. 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].…”

“…Consequently, the fuel injection process is less accurate because of the average diameter of the droplets increases. An inaccurate injection process results in an incomplete combustion process, and hence the power produced decreases [17]; [18]; [19]. A decrease in the resulting power causes the resulting torque to decrease.…”

“…The results show that the higher the ratio of the biodiesel mixture, the less the maximum power produced, the more the specific fuel requirements needed, and the less the torque produced. 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

“…Most vehicles are still powered by internal combustion (IC) engines, among which 29.9% are diesel engines [3]. The main disadvantage of IC engines is the harmful emissions of the fuels, which are nitrogen oxides (NOx), smoke, particulate matter (PM), carbon monoxide (CO), and unburned hydrocarbons (HC) [4]. Various studies are being carried out to reduce harmful emissions: (i) control of the combustion process [5], (ii) additional fuel cleaning or treatment technologies [6], and (iii) the use of catalysts and diesel particulate filters (DPF) [7].…”

The Effect of Nanoparticle Additives on the Lubricity of Diesel and Biodiesel Fuels

Fuel lubricity is an essential property that ensures the longevity end efficiency of diesel CI engines. Nanomaterials have been shown to have the potential to improve lubricity in many different lubricating substances, including fuels. Moreover, the combustion process has also been shown to improve with the introduction of nanomaterials. This study investigated a series of nanoparticles, including carbon nanoplates, carbon nanotubes, aluminum oxide, zinc oxide, and cerium oxide, as lubricity-enhancing additives for selected fuels. Conventional diesel fuel and rapeseed oil methyl ester, referred to as biodiesel, were chosen as base fuels for modification. The lubricity was evaluated according to the standard test method ASTM 6079 using the HFRR tribometer. The leading lubricity indicators were the wear scar diameter, wear volume, and coefficient of friction. In addition, the worn surface analysis was performed to elucidate the lubrication mechanism. The results show that the addition of nanoparticles can improve the lubricity of both investigated fuels. However, the effect differed among nanoparticles and fuels. In summary, carbon nanotubes could be a rational choice for both fuels. In addition, zinc oxide improved the lubricity of diesel fuel, while carbon nanoplatelets and aluminum oxide nanoparticles showed improvements in the lubricity of biodiesel.
