“…At the same time, as can be seen Figure 2, hydrocarbon emissions were significantly reduced at all loads and as can be seen Figure 3, NO emissions were reduced at full loads according to working with gasoline [18]. Experimental studies [18] were realized at 1500 rpm and stoichiometric ratio under 25, 50, 75% and full load conditions. The acetylene was injected into the intake manifold of test engine through the gas injector 500 and 1000 g/h gas flow rates.…”

Researchers have studied on alternative fuels that can be used with gasoline and diesel fuels. Alternative fuels such as hydrogen, acetylene, natural gas, ethanol and biofuels also uses in internal combustion engines. Hydrogen in the gas phase is about 14 times lighter than the air. Moreover, it is the cleanest fuel in the world. On the other hand because of its high ignition limit (4-75%), low ignition energy, needs special design to use as pure hydrogen in internal combustion engines. It is proved that hydrogen improves the combustion, emissions and performance, when is added as 20% to fuels. Natural gas is generally consisting of methane (85-96%) and it can be used in both petrol and diesel engines. Ethanol can be used as pure fuel or mixed with different fuels in internal combustion engines. In this section, the effects of natural gas, hydrogen, natural gas + hydrogen (HCNG), ethanol, ethanol + gasoline, ethanol + hydrogen, acetylene, acetylene + gasoline mixtures on engine performance and emissions have been examined.

“…CO is not only a harmful emission but it also a chemical energy which is not transformed into useful work. 27 The CO emission mainly depends on the combustion behavior of fuel and air-fuel ratio. 28 Thus, the combustion behavior of fuel and air-fuel ratio plays an important role of CO emissions generation.…”

The continuous depletion of conventional fuels requires urgent research work to identify feasible alternative fuels to meet the minimum environmental impact of sustainable energy demand. Due to good combustion characteristics, acetylene being one of such alternative fuel and has the potential to be a future fuel. In this concern, it was decided to perform experimentation on a stationary water‐cooled spark ignition (S.I.) engine in acetylene‐gasolinedual fuel mode. In this experimental investigation, the effects of acetylene and gasoline mixtures on the performance, emissions, and combustion characteristics have been observed. Acetylene was supplied through a modified engine intake manifold at optimized conditions for petrol. The optimum flow rate of acetylene was found by comparing the performance and emissions for 50, 100, and 150 LPH, respectively, at 1600 revolution per minute (rpm). The experimental results showed that the brake thermal efficiency at 100 LPH was the highest amongst all the flow rates under study, throughout the load range in acetylene‐gasoline dual fuel mode. HC, CO, and CO2 emissions for this acetylene flow rate were either low or comparable to that of pure gasoline. Based on this study, it can be concluded that use of acetylene in S.I. engine without any major modifications is feasible without having any adverse effect on the engine performance, combustion, and emissions.

“…They also reported that the highest increase in efficiency was 21.18% maximum in the combustion rate of 19.5:1. In the literature, there have been very few studies on the effects of acetylene gas on performance and emissions in SI engines [27], but the applications in diesel engines were widely studied [26,28]. Therefore, in the present study, it was preferred to test the acetylene gas in a gasoline engine.…”

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.
