“…Untuk mengatasi kelemahan yang dimiliki minyak nabati, beberapa peneliti menggunakan magnet untuk meningkatkan efisiensi pembakaran dan menurunkan emisi (Niaki et al, 2020;Tipole et al, 2022). Penambahan magnet dapat meningkatkan sifat bahan bakar seperti menyelaraskan molekul hidrokarbon yang berpengaruh terhadap perubahan properties bahan bakar sehingga efisiensi pembakaran dan emisi polutan menjadi lebih baik (Jain, 2012).…”

Telah dilakukan penelitian tentang pengaruh orientasi medan magnet terhadap karakteristik nyala api pembakaran droplet Calophyllum Inophyllum. Saat ini, Indonesia masih mengembangkan CPO sebagai sumber bahan bakar terbarukan untuk menggantikan solar. Persoalannya, CPO dijadikan sebagai sumber pangan sehingga akan berdampak pada kelangkaan pangan. Bahan bakar yang digunakan dalam penelitian ini adalah CCIO yang ditambah dengan variasi orientasi medan magnet S-U, U-S, S-S, U-U dan tanpa magnet. Volume droplet yang diuji 1,25-1,31 ml ditempatkan pada thermocouple type K 0,1 mm yang terletak di antara 2 magnet dengan intensitas 1,1 T. Karakteristik nyala api droplet meliputi kestabilan nyala api, ignition delay time, temperatur dan tinggi nyala api. Hasil penelitian menunjukkan bahwa Medan magnet berperan meningkatkan kualitas pembakaran melalui perannya meningkatkan tumbukan antar molekul menjadi lebih kuat karena spin elektron yang dipercepat oleh medan magnet. Pengaruh tersebut dapat dilihat pada arah medan magnet U-S yang menghasilkan temperatur paling tinggi dan ignition delay time yang paling pendek. Ini karena arah kutub magnet berperan sebagai transport O2 dan H2O melintasi droplet sehingga reaksi yang dihasilkan mampu meningkatkan kualitas pembakaran. Sedangkan pada kutub magnet tolak S-S maupun U-U salah satu partikel akan bergerak keluar dari nyala api sehingga reaksi yang terjadi kurang maksimal. Dampaknya, partikel menjadi selaras sehingga menyebabkan ledakan mikro yang terjadi relatif lebik kecil.

“…This research results in 4 to 12% lower fuel consumption as compared to without magnetization. Magnetization also reduces carbon mono oxides, Carbon dioxides, hydrocarbons, and oxides of nitrogen up to 11%, 10%, 18%, and 10% respectively (Niaki et al, 2019). The magnetization of fuel can bring the fuel consumption down up to 15.5% at operating condition and reduction in exhaust emission can also be brought down up to 50% depending upon the strength of the magnet and other operating conditions in a gasoline engine (Rehim and Attia, 2014).…”

Utilization of biodiesel results in lower emissions of hydrocarbons, carbon mono oxide, and smoke. But with the use of biodiesel as fuel emission of Oxides of nitrogen increases along with this some performance parameters also deteriorated. In the present investigation, the fact has been used that, the magnetization of fuels containing hydrocarbon changes the chemical properties as well as orientation and arrangement of molecules of fuel. In this experimental investigation density and calorific values of biodiesel have been determined. In another setup of experimentation on a single-cylinder four-stroke diesel engine, observations are taken with diesel, biodiesel blend containing 20% biodiesel (BD20), and magnetized biodiesel (BD20+MF) as fuel. Results of this investigation show that, the magnetization of biodiesel is not only helpful in increasing performance parameters like brake specific fuel consumption and brake thermal efficiency but also it helps to control the emissions of carbon mono oxide, oxides of nitrogen, hydrocarbons, and smoke. Maintaining the magnetic field just before the entry of the combustion chamber on the fuel line is a little hard, due to the regular increase in temperature of the spot where magnets are kept. It is possible that, if the strength of the magnetic field is increased then, there may be further improvement in performance and engine parameters, as in this investigation only 4000 Gauss Magnetic field has been used.

“…The effects of magnetic field permanent with the intensity of 9,000 G on performance, combustion, and emission characteristics of a spark ignition engine was investigated. They reported that the reduction of 4-12 % in fuel consumption and reduction in 11, 10, 18, and 10 % for CO, CO 2 , HC, and NO x emissions, respectively, compared to gasoline fuel without magnetic condition [16]. Another study on the magnetic fuel treatment on Engine's performance showed a reduction of fuel consumption up to 15.5 % and a reduction in the engine pollutants [17].…”

The effect of the magnetization field on molecular interactions of the bioethanol-gasoline fuel blends was investigated. This technique was promoted to escalate both the increase in combustion energy and reduce emissions in the internal combustion engine. The bioethanol and gasoline fuel are used for the single-cylinder four-stroke engine with different mixtures, namely E0, E10, E20, and E30, serially. Distinguish of electromagnetic field strength with various intensity was given into the fuel by lower than 1,500 Gauss. The absorption intensity and the functional groups of the fuel molecules are characterized in detail by Fourier Transform Infra-Red (FTIR) spectroscopy. The exhaust gas emission and the fuel blends energy are performed using a gas analyzer and calorimeter bomb. By increasing the magnetic field, the de-clustering of the fuel molecules is demonstrated by growing the absorption intensity to be advanced. There is no change in the chemical composition of the fuel as the magnetic induction was enforced. Reduction of namely Carbon monoxide (CO), Nitrogen monoxide (NO), Nitrogen oxides (NOx), and Sulphur Dioxide (SO2) gas emissions was attained to be 29 %, 25 %, 26 %, and 31 % using a magnetic field of 1,419.57 Gauss, respectively, compared to gasoline fuel without magnetic condition. The greater reduction occurs by employing E30 fuel with the same magnetic intensity, achieved up to 38 %, 42 %, 70 %, and 63 %, regularly. The magnetization treatment leads to improved combustion quality with efficiency increases up to 11.32 %. It contributes to perfect combustion in a single-cylinder four-stroke engine system. Reducing gas emissions can also bring a good environmental impact in the life, although the heat energy gradually deteriorated as the fuel utilized more bioethanol blends
