“…It was found that the gaseous and particle emissions were successfully decreased with primary particle diameter being unaffected. Yu et al [175] also reported reductions of gaseous emissions using n-butanol/gasoline blends in SI engine. N-butanol could decrease the accumulation mode of particle number, while at the same time increasing its nucleation mode.…”

The properties of butanol offer more promising results compared to those of lower chain alcohol such as methanol or ethanol. However, butanol as a biofuel has not yet been commercially produced due to its costly process. Butanol is generally produced via the process of Acetone-Butanol-Ethanol (ABE) fermentation and can only be acquired after it was recovered from the ABE solvent. Despite the efforts and recent developments, obtaining higher butanol concentration from ABE fermentation is still relatively expensive and challenging. The idea of using ABE directly in internal combustion engines is then proposed to eliminate the recovery process. Several preliminary studies have reported several promising results of using ABE blends in both gasoline and diesel engines. However, researches in this area are still in the early stages, and thorough investigations are required. This review paper aims to provide essential findings from the latest development in the addition of ABE both with gasoline and diesel fuel in Spark Ignition (SI) and Compression Ignition (CI) engines. A brief discussion on ABE properties will be firstly given before the effects of its addition on SI and CI engine is comprehensively reviewed. The end of this article highlights some possible contributions and research gaps.

“…The reason is that when the ignition is retard to 5 • CA BTDC, the post-combustion plays a dominant role in the oxidation of the accumulated particles. A large amount of nucleation particles are formed in the post combustion region and the number of accumulated particles is reduced [35]. The excessive afterburning can result in the insufficient of the late oxidation of the particles because of the low pressure and temperature, which may be the main reason for the increase in TPN [36].…”

Ethanol has significant potential for the reduction of fuel consumption and the emissions of engines. In this paper, a dual-fuel combined engine test rig with ethanol injected in the intake port and gasoline injected directly into the cylinder are developed and the effects of ethanol/gasoline ratio (Re) on the combustion and emission of particle numbers are investigated experimentally. The results indicate that the peak in-cylinder temperature (Tmax) decreases continuously with the increase of the ethanol/gasoline ratio (Re). For particle emissions, ethanol can significantly reduce the accumulation mode particle number (APN) at low engine speed; and the lowest number of particulates are at G25 (the gasoline ratio is 25% of the fuel) at low load. And at high engine load, the total particle number (TPN) is insensitive to speed with large ethanol fraction and TPN is relatively small. With the decrease of Re (Re < 50%), TPN rises sharply. When the direct injection timing advances, TPN reduces continuously and the effects caused by speed can be neglected. On the contrary, the speed has significant effects on particle emissions at various ignition times. At low speed, increasing ignition advance can cause the increase of the TPN; which is contrary to the effects of particle emissions at medium engine speed. And the effect of ignition timing at high speed on particle number is not obvious. The ignition timing for which the lowest TPN is reached will increase with the direct injection timing advances.

“…Hal ini menyebabkan proses langkah usaha lebih besar dan meningkatkan daya mesin [3]. Penggunaan EGR sedikit meningkatkan daya mesin akibat adanya bahan bakar yang tidak terbakar dalam gas buang yang disirkulasikan masuk ke dalam ruang bakar [11]. EGR tersebut berkontribusi dalam siklus pembakaran berikutnya yang mengakibatkan kenaikan daya mesin.…”
