The impact of methanol and iso-butanol in b20 palm oil methyl ester (POME) fuel blend toward the performance and emission of compressed ignition (CI) engine / Muhammad Aiman Hashim

Methanol and Iso-Butanol have the potential to be a clean alternative for conventional fuel used in internal combustion engine. The issue that arises when using biodiesel is that a high biodiesel blend ratio tends to promote more emission as it alters the physicochemical properties which in turn...

The issue that arises when using biodiesel is that a high biodiesel blend ratio tends to promote more emission as it alters the physicochemical properties which in turn delivers a poor performance. Thus, it requires the investigation of mixing iso-butanol and methanol to study its property in terms of engine performance, physicochemical property, and exhaust emission. This paper aimed to investigate the effect of mixing two alcohol blends such as methanol and isobutanol operating with palm oil methyl ester (POME) biodiesel blend and how it affected the engine performance. Three essentials properties were measured which included (1) density; (2) cetane number; (3) calorific value and (4) kinematic viscosity. Using BENMA 5GF-M Diesel Generator, a single-cylinder 4 stroke diesel engine emission was analysed using a gas analyser. The fuel property was investigated using 7 different tests which consisted of Palm Oil Methyl Ester (POME) (B20) 90 % biodiesel fuel and 10 % iso-butanol (B90iBu10), 90 % biodiesel fuel and 5 % iso-butanol and 5 % methanol (B90M5iBu5), 90 % biodiesel fuel and 10 % methanol (B90M10), 85 % biodiesel fuel and 8 % iso-butanol and 7 % methanol (B85iM7Bu8), 90 % biodiesel fuel and 5 % iso-butanol and 5 % methanol (B80M10iBu10), base diesel fuel (D100) under different load and speed range of 2000~3000 rpm. The results were tested using the unmodified diesel engine by adding two types of alcohol as the additive which were methanol and iso-butanol. It was shown that biodiesel blends increased the BTE by 8 % while BSFC indicated an opposite reaction by decreasing 9 % under the same condition load and speed in comparison to diesel. Based on the results, exhaust emissions for CO and HC decreased with each variation blend. It was shown to decrease by 40 % and 7 % respectively under the same test condition when compared to B20. Further expectation indicates that emission increases the estimate around 18 % on high engine load while lower engine load shows an opposite trend; and it was shown to be true with higher load engine being able to provide lower emission by 27 % difference in comparison to POME. In conclusion, combining iso-butanol and methanol in B20 with a 10 % ratio can display potential results in both exhaust emission and engine performance during engine tests. 2021-02 Thesis https://ir.uitm.edu.my/id/eprint/59826/ https://ir.uitm.edu.my/id/eprint/59826/1/59826.pdf text en public masters Universiti Teknologi MARA Faculty of Mechanical Engineering Abdullah, Nik Rosli (Professor Ts.
