“…Methanol production is very limited [27,28], while ethanol, on the other hand, can be manufactured straightforwardly by the fermentation of sugar from a wide variety of sources [29][30][31]. Ethanol is gaining more attention as it has superior octane number, approximately 108, and is thus often mixed with the gasoline to improve its properties quality [32,33]. The high octane of ethanol has also allowed it to be run using greater compression ratio, i.e.…”

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.

“…Adding ethanol to fuel can increase the mixed fuel octane number. Increasing the octane number of the fuel can reduce the engine knock intensity [20,21]. This means a better combustion efficiency, increasing the power and decreasing different exhaust emissions for the engine, except for NOx [22].…”

The Effects of Port Water Injection on Spark Ignition Engine Performance and Emissions Fueled by Pure Gasoline, E5 and E10

It has been proven that vehicle emissions such as oxides of nitrogen (NOx) are negatively affecting the health of human beings as well as the environment. In addition, it was recently highlighted that air pollution may result in people being more vulnerable to the deadly COVID-19 virus. The use of biofuels such as E5 and E10 as alternatives of gasoline fuel have been recommended by different researchers. In this paper, the impacts of port injection of water to a spark ignition engine fueled by gasoline, E5 and E10 on its performance and NOx production have been investigated. The experimental work was undertaken using a KIA Cerato engine and the results were used to validate an AVL BOOST model. To develop the numerical analysis, design of experiment (DOE) method was employed. The results showed that by increasing the ethanol fraction in gasoline/ethanol blend, the brake specific fuel consumption (BSFC) improved between 2.3% and 4.5%. However, the level of NOx increased between 22% to 48%. With port injection of water up to 8%, there was up to 1% increase in engine power whereas NOx and BSFC were reduced by 8% and 1%, respectively. The impacts of simultaneous changing of the start of combustion (SOC) and water injection rate on engine power and NOx production was also investigated. It was found that the NOx concentration is very sensitive to SOC variation.

This research utilizes corncob waste for making bioethanol by RON 109. The objective of this research is to get the best performace of exhaust emission by mixing gasoline RON 90 from E5, E10, E15, E20, to E25, and 10:1, 11:1 and 12:1 of compression ratio. In addition, the control variable covered 1400 rpm, 2400 rpm, and 3400 rpm engine speed. The testing data of exhaust emission was taken only on the carbon monoxide (CO) and hydrocarbon (HC). The result on this biethanol from corncob waste showed that the lowest exhaust emission on carbon monoxide and hydrocarbon and recom mended to be used was found on E10 fuels at 10:1 compression ratio, and E20 fuels at 11:1 compression ratio. The result obtained from this research demonstrated that the carbon monoxide and hydrocarbon emissions that produced by corncob waste bioethanol were environmently friendly compared to gasoline use only (E0).
