Comparative Assessment of Spray Behavior, Combustion and Engine Performance of ABE-Biodiesel/Diesel as Fuel in DI Diesel Engine

Abstract

This study investigates the impact of an acetone-butanol-ethanol (ABE) mixture on spray parameters, engine performance and emission levels of neat cottonseed biodiesel and neat diesel blends. The spray test was carried out using a high-speed camera, and the engine test was conducted on a variable compression diesel engine. Adding an ABE blend can increase the spray penetration of both neat biodiesel and diesel due to the low viscosity and surface tension, thereby enhancing the vaporization rate and combustion efficiency. A maximum in-cylinder pressure value was recorded for the ABE-diesel blend. The brake power (BP) of all ABE blends was slightly reduced due to the low heating values of ABE blends. Exhaust gas temperature (EGT), nitrogen oxides (NOx) and carbon monoxide (CO) emissions were also reduced with the addition of the ABE blend to neat diesel and biodiesel by 14–17%, 11–13% and 25–54%, respectively, compared to neat diesel. Unburnt hydrocarbon (UHC) emissions were reduced with the addition of ABE to diesel by 13%, while UHC emissions were increased with the addition of ABE to biodiesel blend by 25–34% compared to neat diesel. It can be concluded that the ABE mixture is a good additive blend to neat diesel rather than neat biodiesel for improving diesel properties by using green energy for compression ignition (CI) engines with no or minor modifications.

Assessment of diesel engine performance and emission using biodiesel obtained from eucalyptus leaves

“…In this study we calculated CO2, NOX, CO, HC, and fog emissions. The use of fossil fuels in the engine can lead to a variety of by-products, including HC, CO, NOX, CO2, soot, sulfur oxide, and dust in engine exhaust (Algayyim & Wandel, 2020). Many researchers are working to reduce harmful engine emissions.…”

“…Researchers have studied and reported various alternative feedstock to test the viability in the literature. The investigation was related to nonedible oil-bearing plants, such as Curcas, Jatropha, Soapnut, and Castor beans (Atmanli et al, 2015;Algayyim & Wandel, 2020;Ma et al, 2015), as well as non-edible waste fat from animal carcasses (Balamurugan & Nalini, 2016;Mwangi et al, 2015). BS-6 emission norms are implemented in India since January 2022.…”

Research on Combustion and Emission Characteristics of a N-Butanol Combined Injection SI Engine

“…In recent years, with the rapid development of automotive industries, the depletion of fossil sources and the aggravation of environmental pollution are becoming increasingly prominent [1,2]. Thus the research on green, alternative, and renewable fuels has attracted the attention of many scholars [3,4]. At the same time, advanced technical methods in the field of internal combustion engines are also very important in improving engine performance [5].…”

Determination of the Optimum Blend Ratio of Diesel, Waste Oil Derived Biodiesel and 1-Pentanol Using the Response Surface Method

“…Therefore, biodiesel should be mixed with diesel fuel. In addition to mechanical issues, the raw material supply for biodiesel, insufficient production amount, high NO x emissions, and phase separation problems at low temperatures cause the optimal mixing ratio to be low [9,10]. When diesel-biodiesel mixtures are used in diesel engines, it is stated in the literature that it can be mixed with up to 20% biodiesel (B20) depending on the fuel properties, while diesel engine manufacturers recommend mixing diesel with 7% biodiesel (B7) for the fuel sold at gas stations [11].…”
