“…Different technologies have been developed to address reduce pollutant emissions and minimize fossil fuel consumption in combustion engines. An alternative approach proposes the use of fuel mixtures in these engines, such as blending hydrogen with fossil fuels [4,6,7] and bio-fuels [8][9][10]. In recent years, significant advances have been made on the development of various technologies for commercial vehicles.…”

In this work, a simple methodology to follow the behavior of motorized urban vehicles, from the point of view of personal finances, is presented. Including the acquisition of a new vehicle, the analysis considers the driving distance per week, the average speed, the time spent at rest due to traffic conditions, the evolution of gasoline and electric energy prices, maintenance and services, and local taxes. Herein, two low-range compact vehicles were chosen and compared: one powered by combustion of gasoline, and the other by electric energy stored in batteries. Historical data and trend projections, according to inflation and prices evolution, are taken into consideration. The developed model may help to select adequately a new vehicle, according to the user's needs. A good choice depends strongly on the usage and traffic conditions, the electric vehicle being suitable for large weekly driving distances and heavy traffic, whereas the gasoline vehicle is preferred for short distances and light traffic. The expenses of the vehicles are compared through time, with different scenarios envisaged according to the user's resolution to keep the vehicle for the entire lifespan or to sell it quickly.

“…However, no specific study on the exploration of suitable surfactants for methanol-in-diesel emulsion is available. A few engine studies using methanol-in-diesel emulsions show reduced nitrogen oxide (NO x ) emission and enhanced thermal efficiency [24][25][26]. Contrary, some studies show reduced thermal efficiency and enhanced NO x emission with methanol-in-diesel emulsions [27,28].…”

This study is motivated by the need to present a robust methodology for preparing stable methanol-in-diesel emulsions for use in compression ignition engines with the specific objective of maximizing the methanol content. Specifically, it involved exploring the feasibility of methanol-in-diesel emulsions with conventional surfactants such as Tween-80 and Span-80 and non-conventional surfactants such as 1-dodecanol, pentanol, and butanol. The hydrophilic-lipophilic balance (HLB) values of the surfactant were varied from 7 to 15 to investigate the role of the surfactant HLB on stability of the macroemulsion. It is observed that the macroemulsion with an HLB value of 10 provides the best stability results. Using surfactant HLB value of 10, three macroemulsions with 10 wt.%, 15 wt.%, 20 wt.% of methanol were prepared using ultrasonication. However, only the macroemulsion with 10 wt.% of methanol was observed to be stable for at least 20 days after preparation. Next, the microemulsions of diesel-methanol were produced by using non-conventional surfactants such as 1-dodecanol, pentanol, and butanol. Among these, 1-dodecanol was found out as the most suitable surfactant owing to its ability to form microemulsions with any mixing ratio of diesel-methanol, and its high cetane number (63.6). This study has clearly brought out the strategies for preparing both macro and microemulsions. Overall, the results presented in the current work are expected to aid efforts in adapting compression ignition engines for diesel-methanol fuel blends.

For decreasing the fuel consumption of internal combustion engines, and also reducing the emissions, investigation of the effective parameters on power, emissions, and the combustion phasing is important. In this study, the influence of adding water to a Reactivity Controlled Compression Ignition (RCCI) engine has been numerically investigated. For this purpose, water with different mass fractions was added to the air-fuel mixture. In order to simulate the engine, AVL Fire software was used. The results show that substituting a portion of gasoline fuel with water, up to 10% mass fraction, raises the combustion chamber pressure. In this condition, the production of hydroxyl free radicals, as one of the characteristics for the start of combustion, occurs earlier. Furthermore, Indicated Mean Effective Pressure (IMEP) remains unchanged. By further increasing the water mass the production of hydroxyl radical decreases, and the hightemperature heat release is delayed; also comparing to when water was not added, average temperature of the combustion chamber reduces, while the amount of CO production does not change. Increasing the number of water moles increases the maximum in-cylinder pressures so that compared to pure gasoline mode, by replacing 20% of gasoline mass with water, the indicated mean effective pressure approximately stays the same.
