Performance and Emission of Diesel Engine Fuelled by Commercial Bio-Diesel Fuels in Indonesia

Abstract

The performance and emission of a small diesel engine fuelled by commercial diesel fuel in Indonesia are present in this paper. Various commercial diesel fuels in Indonesia are produced and marketed by Pertamina. As the largest oil company in Indonesia, Pertamina has developed various diesel fuels, namely Solar, Biosolar (B30), Dexlite, and Pertadex. This study explains in more detail the performance, fuel consumption, and emission produced by the four types of fuels, and they were investigated experimentally using a single-cylinder diesel engine at various engine speeds, from 1,000 rpm to 4,500 rpm. The result shows the engine fuelled by Pertadex generates the highest power and torque, while the lowest is generated by the Biosolar fuelled engine. The maximum torque and power generated by the Pertadex fuelled engine are about 25.5 Nm and 7200 W, respectively. The engine fuelled by Pertadex has the lowest brake specific fuel consumption (BSFC) of 0.3037 kg·kW·h, compared to the engines fuelled by the Dexlite, Solar, and Biosolar fuels, with values around 0.3127, 0.3215, and 0.3338 kg·kW·h, respectively. At the same time, the measurement of gas emissions, including CO2, CO, NOx, and HC was conducted simultaneously.

Upgraded diesel‐like fuel from pyrolysis of a waste tire and its engine performance and exhaust emissions

“…43 Higher exhaust levels generally result in poorer engine performance. 45 Additionally, these emission parameters have a hazardous effect on various environments, including water, soil, global warming, and human health in general. 44 The variations in exhaust gas temperatures of the diesel and DAF are presented in Figure 6c.…”

Thermoeconomic Analysis of Organic Rankine Cycle From Napier Grass Biomass

“…OCR applications have been widely applied, from various heat sources such as excess geothermal steam (Permana et al, 2021), solar thermal utilization (Permana et al, 2022), industrial waste heat, and biomass, where biomass is derived from organic material such as trees, plants, and agricultural and urban waste. Additionally, short rotation coppice provides solid biomass, while agriculture also provides by-products and residues such as biowaste (Hlinka et al, 2019) used for bioheat, biopower and biodiesel (Kristyadi et al, 2022). Many authors have researched related ORC system that uses agricultural biomass as a heat source.…”

Biodiesel Performance Improvement with the Addition of Al2O3 Nanoparticles on Diesel Engine

“…This is due to the low Sulphur content of B30. However, the power and torque seem to be lower than diesel fuel [19]. This is due to the high viscosity of biodiesel which causes poor fuel atomization [20].…”
