Effect of acetylene addition in safflower biodiesel fueled CI engine–an experimental study

Comparative assessment of di-ethyl ether/diesel blends on the performance, and emission characteristics in acetylene dual fuel engine

“…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. Furthermore, Balasubramanian and Krishnan 35 observed that BTE was enhanced by 6.6% and 14.3% with diesel and SME respectively for acetylene DFE. On the other hand, Balasubramanian and Purushothaman 34 discovered that at 100% load BTE increased by roughly 6%–13% for neem biodiesel/corn biodiesel acetylene DFE however the gain was not substantial at 50% load.…”

“…33 Purushothaman and Balasubramanian 34 inspected the impact of acetylene introduction to a neem biodiesel (NOME)/corn biodiesel (COME)-fueled to evaluate the performance of a dual-fuel engine. In a separate study, Balasubramanian and Krishnan 35 explore the impact of injecting acetylene gas with intake air using safflower biodiesel (SME) as a pilot fuel on the characteristics of a customized engine’s performance and exhaust emissions. However, Srivastava et al 24 examined the performance of DFE by varying the gas flow rate of 240, 180, 120, and 60 lph, and a compression ratio (CR) of 22, 21, 20, 19, and 18.…”

“…35 The reasons for increased NO x levels for the acetylated biodiesel engine may be due to the higher oxygen content in biodiesel. 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.…”

“…26,27 However, few engine experts have also explored biodiesel/diesel blends as an ignition source. 31,32,34,35 There are certain issues with biodiesel-fueled diesel engines such as higher NOx emissions may be due to their higher oxygen content. 31,35 Different approaches, such as adjusting engine operating settings, treating with antioxidant additives, and combining fuels, have been used by many engine experts to lower the emissions of biodiesel fueled CI engine.…”

Dizel, Dizel/Biyodizel ile Çalışan Bir Motora Kütlece Asetilen Gazı İlavesinin Etkileri

“…Asetilen gazı kısmen silindir içerisindeki yanmanın artmasına ve CO emisyonlarının azalmasına neden olmuştur. Çalışmanın sonuçları literürdeki benzerlik göstermektedir[26]. Asetilen gazı ilavesinin CO emisyonlarına etkisi(3000 d/dak).…”
