The oil that comes out of the transformer leads to environmental hazards when it is disposed into land after the completion of its durability. This research work intends to capitalize on the feasibility of converting this transformer oil into an alternative fuel. The varying quantity of thermally cracked waste transformer oil (20%, 40%, and 60% v/v) is mixed with 10% v/v of Di Ethyl Ether (DEE) and blended with commercial diesel (CD) to make 100% volume. The purpose of this work is to observe the performance of blended fuel when compared to commercial diesel. To meet this objective, the physicochemical properties of blended oil were tested by ASTM standards and evidence for the presence of essential hydrocarbon was proved using FTIR analysis. The notable improvement as observed in WPDE60 blend for BSFC, BTE and in-cylinder pressure by 8.82%, 8.29% and 4.3%, respectively, when compared to CD at full load condition. Whereas, emission performances were reduced by 18.82%, 4.9% and 39.6% for unburned hydrocarbon, CO and smoke density, respectively. Based on the results obtained, WPDE60 blend is resembled the properties of commercial diesel and can be proposed as a fuel alternative for internal combustion engines.

“…Subsequently, Koli and Rao 27 carried out an experimental investigation with an increased CR from 13 to 18 and varied the flow rate of acetylene from 2 to 5 LPM in a variable compression ratio (VCR) engine. However, Sonachalam and Manieniyan 37 investigated the performance by injecting acetylene gas and mahua oil methyl ester on the RCCI engine at a steady flow rate of 4 LPM. According to Koli and Rao, 27 Mechanical efficiency and BTE were found to have increased by 30% and 19%, respectively, for a VCR engine operated with acetylene-diesel fuel.…”

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.

Researchers demonstrated that implementing new combustion technology and optimising fuel quantity results in a significant reduction in traditional fossil fuel usage and emission levels. The Reactivity Controlled Compression Ignition (RCCI) combustion strategy is one of the low temperature combustion technologies, and it is used to reduce the overall combustion temperature while also providing better combustion control. This study looks into RCCI combustion technology, which uses conventional diesel fuel as the high reactivity fuel (HRF) injected through the injector and acetylene gas as the low reactivity fuel (LRF) injected into the cylinder via a modified inlet manifold alongside air. The modified engine setup was tested for performance, emissions, and combustion under various load conditions, as well as different mass flow rates of acetylene gas, a low reactivity fuel that is injected with air. The flow field of the low reactivity fuel at the inlet manifold is analysed using the Computational Fluid Dynamics principle, which is used to determine the best flow rate for improving combustion quality. According to the simulation results, the optimal acetylene flow rate is 3 Litres Per Minute (LPM), and experimentation shows that at 3 LPM acetylene injection, the brake thermal efficiency (BTE) improves by about 3.2%, and emissions such as carbon monoxide (CO), hydrocarbon (HC), smoke intensity, and oxides of nitrogen (NOx) are reduced by about 35%, 17%, 10%, and 21%, respectively.
