“…However, it is additionally influenced by the type of gaseous fuel inducted and its overall concentration in the charge present in the engine cylinder. 29 As a result, the ID of the DFE is heavily influenced by gaseous fuel characteristics. 30 The temperature of the gaseous mixture during compression, preignition heat release, extra heat transmission to the surroundings, and the existence of residual gases are the most critical elements that influence the ID pattern.…”

“…31,35 Khader Basha et al 39 found that the BTE is somewhat lowered with an optimal flow rate of acetylene up to the medium load, whereas at maximum load, it is extremely close to diesel fuel efficiency and may have increased by 6.2%. According to the observation by Lakshmanan and Nagarajan 29 when acetylene was inducted into intake manifold smoke, HC and CO levels were lessened drastically with a slight reduction in BTE relative to neat diesel operation. Moreover, Lakshmanan and Nagarajan 28,30 also found similar results in their study except for a rise in smoke and a reduction in NO x emissions.…”

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.

“…Due to this and other positive properties, it is of significance to investigate the use of acetylene gas as an alternative fuel in internal combustion engines. The physical and chemical properties of acetylene, hydrogen and gasoline (iso-octane) are generally presented in Table 1 [8,[20][21][22][23][24][25].…”

“…Lakshmanan and Nagarajan [21], examined the effects of the addition of 110 g/h, 180 g/h and 240 g/h of acetylene gas to diesel fuel and the different ratios of EGR application on exhaust emissions and engine performance. Acetylene gas added to diesel fuel led to a decrease in NOx, CO and HC emissions and a considerable increase in smoke emissions.…”

In internal combustion engines, the use of gas fuels is becoming widespread due to its advantages such as low cost and being more environmentally friendly. Acetylene is one of the gas fuels seen as an alternative to petroleum-based fuels in internal combustion engines. In this experimental study, the availability of acetylene gas, a gas fuel, at 1600 rpm, 2400 rpm and 3200 rpm engine speeds in a spark plug-fired engine was investigated. Acetylene gas was added to gasoline by 5% and 10% of the mass and its effect on exhaust emissions was studied. The results showed that adding acetylene gas to gasoline by mass increased CO, CO2 and NOx emissions and exhaust gas temperature. HC, oxygen emissions and air supply coefficient decreased.
