“…32 Moreover, many engine scientists have found that overmixing and undermixing between air and fuel are the primary sources of CO formations in diesel engines. 25,27 The difference between CO with a rise in load is illustrated in Figure 9. As already observed by many researchers, CO emissions are lower in diesel engines because of higher burning rates.…”

Many engine specialists have utilized various oxygenated blends such as methyl and ethyl esters, alcoholic fuels, and ether to boost the efficiency of dual fuel engine (DFE). However, there hasn’t been much study done to examine the effects of di-ethyl ether (DEE) in a gaseous fueled engine. Hence, in the present study, the author has examined the impact of the DEE/diesel mixture on the combustion, performance, and exhaust emissions in the acetylene-fueled customized engine. The acetylene is injected at 4 l/min (LPM) through the intake manifold while neat diesel, BD05, BD10, BD15, and BD20 blends are used as ignition sources at various engine loads. It is found that when the engine is operated with an ABD10 fuel combination the brake thermal efficiency (BTE) inclines by 1.7% as compared to standard diesel. The BTE is escalated due to an increased DEE proportion of up to 10% using BD10 pilot fuel at 80% load. However, further increasing the proportion of DEE results is a bit inferior in comparison to conventional diesel mode. Moreover, HC, CO, NOx, and smoke reduce considerably by 27%, 45%, 22%, and 43% respectively in comparison to neat diesel at 80% load while utilizing ABD10 fuel. This may be attributed to the superior physico-chemical properties of the pilot fuel blends permitting legitimate burning of the acetylene-air mixture. Additionally, it is also observed that consumption of neat diesel is decreased by 40% under high load using BD10 mixture as pilot fuel. Consequently, it is recommended to use DEE up to 10% with standard diesel in an acetylene-fueled engine for increasing BTE as well as to mitigate exhaust pollutants.

“…45 While acetylene gas has a probability of being an alternative fuel in ICEs in terms of its high combustion temperature and rate, rapid ignition, and economics, it has not been extensively used too far away as a result of complications in its storing and usage. 46 Raman and Kumar 47 premeditated the effect of the addition of acetylene gas in a compressed engine. For this purpose, they added 5 and 10% butanol to the fuel used as pilot fuel.…”

Performance and Emission Characteristic Analysis of a Gasoline Engine Utilizing Different Types of Alternative Fuels: A Comprehensive Review

2021

Gasoline is a liquid composed of hydrocarbons, refined from crude petroleum, and characterized by a boiling point. It is difficult to regularly refine these oils, and their scarcity in natural resources makes it problematic to refine them. Gasoline engines produce fewer toxic emissions, like NO x , CO, and CO 2 . On the basis of economical and natural concerns, gasoline can be put back by many alternative fuels. It can be powered by alternative energy sources, like hydrogen, natural gas, ethanol, acetylene, propane, biogas, etc. The performance of these types of fuels in an internal combustion engine is very charming and appropriate for nature. Hydrogen is sustainable, and the amount of energy necessary to create hydrogen is small. Hydrogen engines are more prominent at approximately 30% compared to gasoline engines in terms of direct injection. Ethanol causes 80% less CO emissions after it has been properly blended with gasoline. Natural gas fueling stations are expanding in popularity. After the natural gas percentage is increased in the fuel, high efficiency is achieved at a sustainable performance in the 0.7−0.9 equivalent ratio. (G + 1000 g/h acetylene) has a higher brake thermal efficiency (G + 500 g/ h acetylene). These vehicles, after all, have seen considerable increases in terms of fuel economy, total performance, and substantially reduced emission standards. This study aims to compare various alternative fuels with gasoline by analyzing their availability, engine tests, toxic element emissions, price, etc. Furthermore, a selection criterion for alternative fuel is given in various measuring scales that will be helpful for choosing alternative fuels because fossil fuels are running out.

“…A 10% i-butanol content (in the diesel-ibutanol blend) demonstrated an increase in BTE (brake thermal efficiency) and a decrease in BSFC (brake-specific fuel consumption), which is assumed to be due to decreased injection pressure [58]. Additionally, when using this fuel blend, exhaust gas temperature (EGT) was lower compared with that of conventional diesel [59].…”

The article analyses energy and environmental operating parameters of a compression ignition internal combustion engine running on HVO-biobutanol and castor oil fuel blends, also comparing them with parameters of an engine running on convection diesel. Since biobutanol is known for poor lubrication characteristics, it was mixed with 5% of castor oil. The obtained blend of biobutanol and castor oil was mixed with HVO at 2/95, 10/90, and 20/80 v/v and fed to the compression ignition internal combustion engine. The presented physicochemical indicators justified the use of the said fuel blends. Constant engine crankshaft speed of 2000 rpm and a variable load expressed as BMEP of 0.1–0.9 MPa was selected in the research. When using the biobutanol–castor oil additive (hereafter simply biobutanol additive) in HVO, an increase in the rate of heat release (ROHR) and the convergence of its value to that of to conventional diesel fuel was observed. A decrease in BTE values was also observed with increasing biobutanol concentration in the blend. Increasing concentration of biobutanol in blends led to an increase in BSFC both in terms of volume and mass; HC and NOx emissions grew as well, but smoke emissions declined, and no material changes in CO and CO2 emissions were observed.
