“…From their experimental investigation on fumigation of methanol by two different approaches, higher power regimes were noticed, both NO X and smoke were reduced at higher load. In another similar work, Udayakumar et al [182] endeavored to fumigate methanol in the inlet manifold of a single cylinder diesel engine. Since methanol ought to produce cooling effect in the inlet manifold when being injected, they employed a heat exchanger to heat the inlet air.…”

“…Since NG prices have recently decreased due to the presence of shale gas in the US, NG dual-fuel has also been the subject of increasing interest in road transport. Though the dual fuel concept has traditionally been perceived as natural gas combustion, there are several liquid fuels that have been studied in dual fuel combustion: ethanol [9][10][11][12][13][14][15][16][17], methanol [18][19][20][21][22], butanol [23] Liquefied Petroleum Gas (LPG)/propane [24][25][26] and gasoline [27,28]. A common feature of these three fuels is that they are all well suited for SI engines and have similar combustion characteristics, e.g.…”

In this experimental study, the ethanol/gasoline blend E85 was used as the primary fuel in a dual-fuel combustion concept. The E85 blend was injected at low pressure into the intake manifold and the mixture was ignited via a diesel fuel injection near top dead centre. The research engine was based on a heavy-duty diesel engine equipped with a common-rail injection system. Only the duration of the diesel injection was modified in the diesel injection system during the tests-the other diesel injection parameters were not changed. The goal was to study the possibilities of using the waste material-based E85 ethanol blend on dual-fuel concept as a promising future bio-fuel option. The results were promising, though the engine was not optimised for the combustion concept being studied and minimum modifications were done to the engine. High E85 rates (up to 89%) by energy content were achieved, especially under medium load conditions. On the high and low load portions were lower, but the E85 rates were higher than 30% even in these cases. For most of the cases, the limiting issue was the pressure rise rate, but in cases with the highest portions of E85 the limiting factor was the minimum quantity of the diesel fuel enabling two phase diesel fuel injection. In all cases the E85 increased carbon-monoxide and un-burned hydrocarbon emission, but the nitrogen oxide emission decreased simultaneously in most of the cases. Smoke emissions were low in all cases, but at highest E85 rate smoke emissions further decreased to near zero value.

The present paper tries to investigate the fundamental aspects of air pollutants, fuel properties, and engine performance during transient operation of naturally aspirated and turbocharged diesel engines in addition to comparing them to new experimental results using methanol as an oxygenate additive. The additives that can reduce the soot emission are various oxygenate alcohols (methanol, ethanol, and n-butanol). The additives that are used for improvement of the fuel properties (cetane number enhancers) are tertiary additives. Meanwhile, the additives used for increasing the engine performance are nanometallic additives, such as, silica, alumina, cerium, and manganese. This research demonstrates the effect of various additives on the performance of the diesel engine, emission, and diesel fuel properties by different models, to address the optimum and best conditions. This paper shows the effect of different oxygenate additives on the reduction of the soot formation, although this effect was different in the different models adopted. This research also illustrates the effects of tertiary additives and nanometallic additives on the fuel properties and engine performance, respectively, owing to the type of additive (additive name). Moreover, this paper examined the effect of other conditions (engine load, engine speed, and injection timing) on the above-mentioned responses.
