“…In the test results, it was observed that biodiesel blends increased the incylinder pressure and heat release rate amount. Under full load conditions of the engine, NOx emission increased by 2.9% and 5.98%, CO emission decreased by 14% to 17.2% with OP10 and OP20 biodiesel fuels compared to diesel fuel, and thermal efficiency was 5.73% and 13.05% found that it decreased (Uyumaz et al 2020).…”

In this study, biodiesel fuel produced from crambe abyssinica plant using KOH and NaOH catalysts was mixed with standard diesel fuel and the effects on engine performance, combustion and emission were experimentally investigated. During the experiment, in-cylinder pressure data were specified for each test fuel and engine load. In addition, measurements of HC, NOx, CO and smoke emissions were carried out. With the obtained experimental data, parameters such as heat release rate, combustion stages, thermal efficiency, indicated mean effective pressure (imep), ignition delay, ringing intensity and specific fuel consumptions were calculated and evaluated in MATLAB/Simulink environment. It was concluded that the highest thermal efficiency values were achieved with CAKB25 mixed fuel under all engine load conditions. It has been determined that using crambe abyssinica KOH catalyst (CAK) and crambe abyssinica NaOH catalyst (CAN) biodiesel fuel mixtures on diesel engine instead of standard diesel fuel improves CO, HC, and smoke emissions but increases NOx values slightly.

“…And at a constant biodiesel percentage and compression ratio, the effective power increases continuously, the effective efficiency increases to the specified value, and then begins to decrease with the engine load increase. Uyumaz et al [11] studied the effects of poppy oil biodiesel-diesel fuel blends on the combustion, performance, and emissions of a single-cylinder, four-stroke, naturally aspirated, direct injection diesel engine with a compression ratio of 18:1 under different engine loads. It was reported that the poppy oil biodiesel fuel could be used in a single diesel engine without any modification.…”

At present, the preparation cost of biodiesel is still higher than that of diesel. Thus, directly using vegetable oil before transesterification can greatly reduce the cost. This study investigated the application characteristics of the direct use of crude palm oil (CPO) in a common rail direct injection (CRDI) diesel engine. In this study, the combustion characteristics, engine performance, and emission characteristics of the CRDI diesel engine operated with CPO0 (neat diesel fuel), CPO10 (10% CPO blended with 90% diesel fuel by volume), CPO30 (30% CPO blended with 70% diesel fuel by volume), and CPO50 (50% CPO blended with 50% diesel fuel by volume) at three idling speeds (750 rpm, 1500 rpm, and 2250 rpm) were evaluated. The results obtained from the experiment elucidate that combustion starts earlier by increasing the idling speed. The addition of CPO to diesel fuel resulted in a decrease in the peak in-cylinder pressure at all idle speeds and a decrease in the maximum heat release rate (HRRmax) at 750 and 1500 rpm, but an increase in HRRmax at 2250 rpm. On the other hand, increasing idle speed is beneficial for reducing carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx), but it increases smoke emissions. In addition, adding 10% and 30% CPO to diesel fuel can reduce both HC, NOx, and smoke emissions simultaneously.

“…Lesser calorific value and higher viscosity of biodiesel fuel result in increased specific energy consumption, which in turn causes lower brake thermal efficiency. (Cheikh et al, 2016) Several studies have been conducted all over the world Safieddin Ardebili et al, 2021Uyumaz et al, 2020) and reported the influence of blending of biodiesel with mineral diesel on engine combustion and emissions. Some studies reported that the viscosity and volatility of biodiesel can be improved by adding oxygenated additives.…”

Biofuels are one of the most sought-after renewable energy sources to overcome the current energy crisis in the world. Diesel blended with esters derived from oils has shown appreciable results for its use in compression ignition engines. In this work, B20 (20% biodiesel + 80% diesel by volume) fuel blend comprising 80% diesel and 20% biofuel extracted from waste cooking oil is used as a fuel. Two different metallic oxide nanoparticles (NPs), namely, cerium oxide (CeO 2 ) and aluminium oxide (Al 2 O 3 ) each having size of 30 nm, are dispersed in B20 biodiesel blend and used to investigate their combined influence on engine combustion. Experiments are conducted to study the engine exhaust emissions of a single cylinder four-stroke diesel engine running at constant speed of 1,500 rpm with varying engine loads. Experiments are carried out with B20 fuel and adding mixtures of CeO 2 and Al 2 O 3 nanoparticles in 50-30, 40-40 and 30-50 ppm, respectively, to B20 biodiesel blend. Responses recorded are the emissions of CO, HC, CO 2 , NOx and smoke. The results reveal that, on adding the nanoparticles, the engine observed a smooth combustion with reduction in the exhaust emissions compared to neat B20 biodiesel operation. B20 blend with 50 ppm of CeO 2 and 30 ppm of Al 2 O 3 nanoparticles showed lower exhaust emissions compared to other fuel blends. For the best fuel blend, CO, HC, NOx and smoke are reduced by 57.3%, 22.3%, 24.3% and 7.36%, respectively, compared to neat B20 operation.
