“…The percentage of biodiesel from palm oil remained up to 10%, due to national legislative standards. In general, the percentage of diesel replacement remained below 20% since research shows that below 20% biodiesel has no negative effect on the engine, and the properties of fuels remain relatively close to diesel [36][37][38]. The properties of diesel and biodiesel blends were measured in a Test Laboratory, following the use of the US ASTM standard tests.…”

This study investigated the influence of different biodiesel blends produced from residual sunflower oil and palm oil from agroindustry liquid waste on the characteristics of the combustion process, performance, and emissions in a single-cylinder diesel engine. For the analysis of the combustion process, a diagnostic model was developed based on the cylinder pressure signal, which allows the calculation of the heat release rate, the accumulated heat rate, and the temperature in the combustion chamber. This is to assess the influence of these parameters on engine emissions. The experiments on the diesel engine were carried out using five types of fuel: conventional diesel, two biodiesel blends of residual palm oil (PB5 and PB10), and two biodiesel blends formed with palm oil and sunflower oil residues (PB5SB5 and PB10SB5). The engine was running in four different modes, which covered its entire operating area. Experimental results show that the in-cylinder pressure curves decrease as the percentage of biodiesel in the fuel increases. Similarly, the results showed a decrease in the heat release rate for biodiesel blends. The diagrams of the accumulated heat release curves were larger for fuels with higher biodiesel content. This effect is reflected in the thermal efficiency of biodiesel blends since the maximum thermal efficiencies were 29.4%, 30%, 30.6%, 31.2%, and 31.8% for PB10SB5, PB5SB5, PB10, PB5, and diesel, respectively. The emission analysis showed that the blends of biodiesel PB5SB5 and PB10SB allowed a greater reduction in the emissions of CO, CO2, HC, and opacity of smoke in all the modes of operation tested, in comparison with the blends of biodiesel PB5 and PB10. However, NOx emissions increased. In general, biodiesel with the percentage of residual sunflower oil does not cause a significant change in the combustion process and engine performance, when compared to biodiesel that includes only residual palm oil.

Gaseous fuel induction in a compression ignition (CI) engine has picked up much attention over the most recent few years, particularly when it is produced by using renewable sources. In this study, hydrogen-enriched biogas (HEB) was used as a gaseous fuel and co-combusted in dual-fuel CI engine.Experimentation was carried out on a 3.5-kW CI engine test rig in the brake mean effective pressure range between 0 and 3.5 bar, as well as, HEB between 0.1 and 0.5 kg/hr. HEB induction effects on various engine characteristics (combustion, performance, and emission) were studied at rated engine speed (1,500 rpm). Results revealed that the peak cylinder pressure and ignition delay period increased with increasing HEB proportion (0.1 to 0.5 kg/hr) as compared with diesel mode. The calorific value of HEB (57.0 MJ/kg) is higher than diesel (42.0 MJ/kg), which led to improved BTE in dual-fuel mode. The emission results showed that with an increase of HEB rates, the NOx emission mildly decreases, but smoke opacity and hydrocarbon emissions majorly reduce. Thus, the HEB induction has great potential to be a feasible technological solution to overcome low BTE and high hydrocarbon emissions in biogas operated CI engines.

“…These two reasons have led researchers to explore alternative fuels that can reduce both fossilfuel dependency and engine harmful emissions [9,10]. Some alternative fuels from renewable resources have been investigated extensively in the last two decades such as biodiesel [11][12][13][14][15] and bioalcohol (ethanol and butanol) [16]. A derivative alcohol fuel such as fusel oil [17,18] and other oxygenated biofuels such as 2,5-dimethylfuran (DMF) [19,20] have also been investigated.…”

Several studies on ethanol as a biofuel have been comprehensively carried out. Today, a growing interest in longer chain alcohols has emerged due to their favourable physical and thermodynamic properties. Butanol or butyl alcohol with 4-carbon structure (C4H9OH) is a more promising biofuel as it outweighs methanol and ethanol in several ways. The production cost of butanol has been gradually reduced, and rapid progress in the development of its production technology has allowed butanol to be produced more effectively. However, studies on the effect of butanol on gasoline or spark ignition (SI) engines are not as comprehensive as the abundant research of ethanol. This paper highlights recent novelty and contribution of butanol addition in SI engine. Results of new approaches on the engine’s performance, combustion and emission characteristics are summarised. Reviews from this paper suggest that there are some gaps in the addition of butanol found in the literature. Thus, several encounters and forthcoming research directions are outlined in the final section of this review article, highlighting several possible contributions that have not yet been carried out using butanol as a biofuel in a gasoline engine.
