“…The ash normally comes from the burning of lubricating oil, whereas the soot is formed in the fuel-rich areas of the combustion chamber after the initial diffusion stage of combustion climaxing at the completion of the fuel-injection time (Matsui et al 1982). A simultaneous reduction of PM was achieved in all but one of the same studies (Ishida and Chen 1994;Hsu 1986;Tsukahara and Yoshimoto 1992) the exception being a study utilizing a big bore, two-stroke diesel engine with low injection pressure (Henningsen 1994). The observed reductions in the formation of PM were attributed to the microexplosions phenomena (Fig.…”

Emulsion fuel is an unconventional fuel for diesel engines, which can be used without modifications in the engine. The benefits of an emulsion fuel include lowering the emissions of nitrogen oxides (NO x ) and particulate matter (PM) which are harmful to health and cause diesel engines to suffer. This paper explains in detail the effect of water in the emulsion fuel on the emissions of NO x , PM, carbon monoxide (CO), hydrocarbon (HC), smoke and exhaust temperature. Experimental results from various researchers show a decrease in the NO x and PM emissions simultaneously. However, the results with the increasing water percentage in emulsion fuel are not consistent for HC and CO emissions. The water content in emulsion fuel affects the combustion and reduces the peak temperature in the combustion chamber. On the other hand, microexplosion phenomenon occurs and causes an increase in the volatility of diesel fuel which improves the combustion efficiency.

“…In order to achieve air quality requirements that significantly reduce Sulfur (S), it is necessary for vehicles to use Euro 3 and above within other parameters such as Benzene (C 6 H 6 ) and olefins or aromatics, which able to significantly reduce [11]. Low grade diesel fuel was widely used in nondeveloping countries and also in some developing nations [12]. Fuel quality contains very high Sulfur (S), Lead (Pb), Benzene (C 6 H 6 ) and olefins or aromatics causing severe damage to the environment and also to the diesel engine.…”

Abstract. An experimental investigation on exhaust emissions with emulsion fuel was conducted in a diesel engine that equipped with a "Real Time Non-Surfactant Emulsion Fuel Supply System, RTES" under four different loads operations (1, 2, 3 and 4 kW). RTES is a mixing device that able to produces non-surfactant emulsion fuel which is one of the alternative ways to improve the exhaust emissions of diesel engine, especially Nitrogen Oxides (NOx) and Particulate Matter (PM). As for the test fuel, neat diesel (D2) and tap water-in-diesel emulsion fuel (W/D) are tested as a comparison. Based on the experimental results, emulsion fuel decrease NOx radically compare to D2 in all load conditions with an average reduction of 18.99% respectively. As for the PM, emulsion fuel is lower compare to D2 at all load conditions and lowest at high load. However, tap water emulsion fuel shows high formation of Carbon Monoxide (CO) at all load conditions which due to lower combustion temperature. This significant increment is aligned with the reduction of NOx emissions.

“…In this case, also smoke emissions as well as unburned hydrocarbons were reduced, even by 80% when the engine was fuelled with the W-D emulsion, in comparison with standard diesel oil. Henningsen [13] investigated a two-stroke engine powered with a W-D emulsion containing 25% water. He showed that the engine powered with the tested emulsion can generate even 30% lower emission of nitrogen oxides in comparison with diesel fuel.…”

In this study, an experiment was conducted to examine the AVL research diesel engine using two kinds of waterdiesel (W-D) fuel microemulsions. These W-D mixtures contained 3.5 and 7.0% by volume (%, v/v) of distilled water dispersed in regular diesel fuel meeting the requirements of the EN590 standard. The engine was tested under the conditions of low, moderate and higher loads. This research was focused on the emission characteristics of nitrogen dioxide (NO 2) and nitrogen monoxide (NO). Cumulative emission of NO x was also analyzed before being further discussed. The obtained results of this study showed that the addition of distilled water to the regular diesel fuel has a minor effect on the variation of the nitrogen oxides emission. It was confirmed that NO is the main component of NO x detected in the exhaust stream of the AVL engine fuelled with all tested fuels. It proves that the thermal mechanism of the nitrogen oxides formation was dominant in the combustion process. Moreover, it was found that the addition of water dispersed as microemulsion in diesel fuel had a minor effect on the reduction of the NO x emission.
