“…23 In addition to the investigations mentioned above, numerous studies have shown the relationship between ICE emissions with health problems 24,25 and environmental deterioration. 26 For example, CO can cause death in high concentration because this compound mix with the blood faster than oxygen, UHC are usually composed by polycyclic aromatics (PAH) guilty of carcinogenic problems; the NOx are responsible for acid rain, photochemical smog, and ozone reduction. Also, PM emitted by the ICEs are composed of particles with different characteristics and properties according to their size, chemical composition, solubility, and origin.…”

This research/article aimed to analyze the influence of an after-treatment system (ATS) on emissions of a heavy-duty spark-ignition (HD-SI) engine fueled with liquified D:\APP-SERVER\3B2\3B2AUTO\LOGO\petroleum gas (LPG), in the context of current Euro VI emissions requirements. The ATS is composed by a three-way catalyst (TWC) in series with a diesel particle filter (DPF). Emissions testing were carried out on an engine test bench according to homologation procedures, performing both world harmonized stationary cycle (WHSC) and world harmonized transient cycle (WHTC), to study the effects of the engine operating parameters on pollutant emissions behavior and ATS performance during steady and dynamic states, respectively. Instruments used were a gas analyzer Horiba MEXA ONE to measure gaseous emissions, HORIBA OBS ONE PN to measure particle matter (PM) concentration, and spectrometer TSI EEPS 3090 to measure PM concentration and particle size distribution (PSD). The results showed some important aspects such as the effects of engine speed and load on pollutant emissions formation and ATS performance, the influence of the three-way catalyst (TWC) on particulate matter (PM) reduction due to the relationship between volatile unburned hydrocarbons (UHC) and the emergence of nucleation-mode particles, stressing that ATS implementation is mandatory to meet the current emissions requirements.

“…They also reported the emergence of new nanocatalysts with capability of producing high catalytic efficiency in moderate operating conditions. Even though biodiesels possess numerous advantages, there exist some critical issues when they are fueled into a typical diesel engine, which are their nature of oxidation instability, and the presence of aldehydes, carboxylic acids, ketones, and fatty acids in their emissions Among fatty acids, the unsaturated fatty acids, in particular, could cause enhanced oxidation of the biodiesel in diesel engines leading to corrosion within engine parts in conjunction with the presence of greater free fatty acids, oxygen, and water molecules included within the biodiesel [12,13]. This increased rate of free fatty acids is caused by the incompleteness of the biorefinery process followed by hygroscopic properties of biodiesel that help to improve the tribology and corrosion parameters of the engine.…”

The present work proposes an investigation to assess the viability of novel mineral-based biodiesel developed from chlorella emersonii, a species of green algae. A single-cylinder, water-cooled, the four-stroke diesel engine was used in the experiments. Among the different biodiesel blends that were investigated for their tribological and engine performance characteristics, the B40 chlorella emersonii biodiesel blend exhibited the least coefficient of friction and while B40 and B100 blends offered enhanced performance characteristics. Comparatively, the remaining test fuel blends attained higher steady-state coefficient rates of friction: B10 (30.8%), B20 (16.21%), B60 (7.7%), B90 (18.2%), and mineral diesel (39.44%). B100 fuel blend exhibited the highest Flash temperature parameter of 83 oC while mineral diesel exhibited the lowest at 58.4 oC. These values were inversely proportional to their respective wear scar diameters with mineral diesel showing the highest wear scar diameter at 0.768 mm. The diameter of the wear scar yielded minimal wear for fuel blends from B40 to B100 and mineral diesel. The corrosion physiognomies of the test fuel blends were investigated, and the B40 fuel blend demonstrated lower corrosion characteristics with a steady-state coefficient of friction of 0.081 when compared to the other fuel blends. The investigated gasoline blends (B40 and B100) were tested on a diesel engine, which demonstrated reduced brake thermal efficiency and a wider range of brake-specific energy consumption under peak load circumstances. The B40 fuel blend exhibited better emissions performance during testing where the unburnt hydrocarbons, carbon monoxide, and smoke emitted were 10.94%, 15.7%, and 23.4% less than mineral diesel.

“…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.
