Diesel engines are the major contributor of Nitrous oxide (NOX) and other environmental pollutants. The higher combustion temperature of the diesel engine causes the NOX emissions. Water in Diesel Emulsion (WiDE) is one of the best techniques for controlling NOX emissions. The vaporisation of water at the combustion chamber leads to reduce the peak temperature. The present investigation was carried out at different loads with various compression ratios (CR) of 17, 17.5 and 18. The engine was run with WiDE10 as the primary and hythane10 at a flow rate of 5 liters per minute (lpm) used as the secondary fuel in the dual-fuel engine. In a dual-fuel mode CR18 exhibits the maximum Bthe of 32.39%, it shows 16.85% improvement and a drastical reduction of NOX emissions about 30.5% than the diesel. It also shows 23.78% of reduction of smoke opacity CR18 when compared to that of diesel. © 2019, © 2019 Informa UK Limited, trading as Taylor &amp; Francis Group.

Evaluating the characteristics of a diesel engine fuelled with water in diesel emulsion and hythane gas in a dual-fuel mode

International Journal of Ambient Energy

The present work primarily focused on the impact of emulsified fuel in a diesel engine on environmental pollutant reduction. In this investigation, Water in Diesel Emulsion10 (WiDE10) was used as a fuel. It was injected at three different injection timings (IT). The first one was at a normal injection timing of 23° Before Top Dead Centre (BTDC), the second one was advanced injection timing of 26° BTDC and the third one was the retarded injection timing of 20° BTDC. The higher water content emulsified fuel showed the maximum diminishing of oxides of nitrogen (NOX) emissions. This is due to the effect of lower combustion temperature. The brake specific fuel consumption (BSFC) increased with an increase in water quantity. This is due to the decrease in the overall heating value of the fuel mixture. The combustion efficiency got improved for WiDE when compared with the pure diesel. This effect can be attributed to a micro-explosion phenomenon. © 2019, © 2019 Informa UK Limited, trading as Taylor &amp; Francis Group.

Abating environmental pollutants of a diesel engine by using emulsified fuel

The Water Diesel Emulsion (WiDE) fuel shows nepotism in terms of environmental and economical aspects. In the present investigation, WiDE is used as fuel for the diesel engine. Here, WiDE was prepared with various water percentages in the range of 0 to 15 using the non ionic surfactant with a HLB value of 6.31. The WiDE was prepared by using ultrasonic probe Sonicator and the mean diameter of water droplet was measured by using the dynolite microscope. The investigation was run on a diesel engine with WiDE as fuel, for finding the effect of performance, emission, and combustion characteristics. The engine was operated at a compression ratio of 17.5 with variable loads from 0 to 100% with an increment of 25% load. From the obtained results, it shows that emulsion fuels show less NOX emission when compared with the pure diesel. The amount of water concentration shows the greater effect on NOX emissions. From the obtained results, WiDE 10 shows greater break thermal efficiency due to micro explosion phenomenon and the WiDE 15 shows higher cylinder pressure. But the emulsion fuel produced higher HC and CO2 emissions when compared with the diesel. © TJPRC Pvt. Ltd.
