Energy demand from the community, which continues to increase has resulted in depletion of petroleum (fossil) energy in recent years. Many researchers have sought to find alternative fuels to replace dependence on conventional energy. The mixing of alcohol into diesel fuel has also been carried out by several previous researchers. The main focus of this research is to investigate the combustion performance of diesel engines using a mixture of biodiesel-butanol-water and diesel (B5Bu5W5). This research experiment used a single-cylinder diesel engine with different speeds at 25% and 50% engine load. The experimental results show that the maximum cylinder pressure reaches 72.32 bar when the engine load reaches 50%. While at 25% engine load press the maximum cylinder 33.62 bar. The heat dissipation for 50% engine load is also higher than the engine load 25% respectively 34.39% and 33.62%. Overall results show that cylinder pressure increases when the load and engine speed increase. However, the combustion time is a little slower than when using pure diesel fuel.

“…The maximum heat release at 25% load is obtained at 1800 rpm engine speed, while for 50% load is recorded at 2400 rpm. The maximum yield of heat release is slightly lower than research by [24]. The maximum heat release in their study was 41.05% for speeds of 1800 and 2400 rpm.…”

“…Isopropanol improves the cold-flow limit in blends with both diesel and biodiesel, cooling it when operating at low temperatures [32]. 15% Isopropanol content in diesel allows for improved engine performance, lower smoke and NO x emissions (at low to medium loads), but increases brake specific fuel consumption (BSFC) due to its lower calorific value [33]. Increasing the isopropanol content to 55% compared to diesel led to an increase in nitrogen oxide emissions (by an average of 139%), a reduction in carbon monoxide emissions (45%) and an increase in CO 2 emissions (by an average of 17%).…”

This article presents the results of a study of energy and ecological indicators at different engine loads (BMEP) adjusting the Start of Injection (SOI) of a Compression Ignition Engine fuelled with blends of diesel (D), rapeseed methyl ester (RME)-based biodiesel and isopropanol (P). Fuel blends mixed at D50RME45P5, D50RME40P10 and D50RME30P20 proportions were used. Alcohol-based fuels, such as isopropanol, were chosen because they can be made from different biomass-based feedstocks and used as additives with diesel fuel in diesel engines. Diesel fuel and its blend with 10% alcohol have almost the same thermal efficiency (BTE). In further examination of energy and ecological indicators, combustion parameters were analysed at SOI 6 CAD BTDC using AVL BOOST software (BURN subprogram). Increasing alcohol content in fuel blends led to a reduced cetane number, which prolonged the ignition delay phase and intensified heat release in the premixed combustion phase. Higher combustion temperatures and oxygen content in the fuel blends increased NOx emissions. Lower C/H ratios and higher O2 levels affected by RME and isopropanol reduced smoke emissions.

“…Ahmed et al [14] studied the effect of a nanomaterial additive on diesel-n-heptane blends in a diesel engine and found an increase in the engine performance. Mehmet [15] investigated the effect of fuel injection pressure on a diesel engine and found that higher fuel injection pressure decreased the brake-specific fuel consumption (BSFC) and enhanced the brake thermal efficiency (BTE) at low speed. Varying the injection pressure seems to be a promising strategy to improve combustion characteristics; it is the main factor that determines fuel stratification inside the chamber and highly affects the combustion process.…”

Experimental research was conducted on a rapid compression and expansion machine (RCEM) that has characteristics similar to a gasoline compression ignition (GCI) engine, using two gasoline–biodiesel (GB) blends—10% and 20% volume—with fuel injection pressures varying from 800 to 1400 bar. Biodiesel content lower than GB10 will result in misfires at fuel injection pressures of 800 bar and 1000 bar due to long ignition delays; this is why GB10 was the lowest biodiesel blend used in this experiment. The engine compression ratio was set at 16, with 1000 µs of injection duration and 12.5 degree before top dead center (BTDC). The results show that the GB20 had a shorter ignition delay than the GB10, and that increasing the injection pressure expedited the autoignition. The rate of heat release for both fuel mixes increased with increasing fuel injection pressure, although there was a degradation of heat release rate for the GB20 at the 1400-bar fuel injection rate due to retarded in-cylinder peak pressure at 0.24 degree BTDC. As the ignition delay decreased, the brake thermal efficiency (BTE) decreased and the fuel consumption increased due to the lack of air–fuel mixture homogeneity caused by the short ignition delay. At the fuel injection rate of 800 bar, the GB10 showed the worst efficiency due to the late start of combustion at 3.5 degree after top dead center (ATDC).
