“…Figure shows that all the COV imep results are acceptable due to being lower than 10% . Generally, five percent value of COV imep is considered as the value of the cutoff for the combustion stability . At low torque 3.4 Nm, increasing methane composition in gas fuel increased the value of COV imep .…”

However, increasing the torque decreased the COV imep because higher load mean increases the amount of fuel injected and helps rich fuel mixture in the combustion chamber.…”

Biodiesel fuel and biogas fuel as promising alternative energy sources for dual‐fuel‐mode diesel engine attract more researchers. Therefore, this study highlights the dual‐fuel mode (DFM) operation of diesel engine using biodiesel fuel from used cooking oil and simulated biogas fuel with different methane contents (M40, M60, M80, and M100) on the combustion, rate of heat release, combustion stability, and performance. The observation of diesel engine was conducted by varying the torques from 3.5 Nm, 10.5 Nm, 17.6 Nm, and 24.6 Nm and by varying the engine speeds from 1800 rpm, 2000 rpm, 2200 rpm, 2400 rpm, and 2600 rpm, respectively. It was found that in DFM at a low torque the thermal efficiency decreased, but biogas replacement, biogas energy, and sfc values increased. The relation of the results of biodiesel replacement, biogas energy ratio, and brake thermal efficiency with methane content ratio in DFM show that the methane content ratio has the maximum effect in DFM. In addition, the carbon dioxide content in the biogas can enrich the brake thermal efficiency. The combustion stability of all conditions (1.7%‐4.89%) is still acceptable.

“…There are several studies in the literature on the use of DEE in diesel engines as a fuel or fuel additive in various diesel engine fuels. For example; as pure [16], with diesel fuel [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32], with diesel-ethanol blends [33][34][35][36][37][38][39][40], with dieselferric chloride blends [41], with diesel-kerosene blends [42], with diesel-acetylene gas dual fuel [43], with biogas [44], with liquefied petroleum gas [45], with diesel-natural gas dual fuel [46], with ethanol [47,48], with various biodiesel fuels [49][50][51][52][53][54][55][56][57][58][59][60][61][62][6...…”

“…CO emissions reduced with increased DEE ratio in diesel fuel while they increased with increased loading conditions. Lee and Kim [23] declared that CO forms as a result of incomplete combustion due to insufficient oxygen in the air-fuel mixture. The level of CO emissions is controlled primarily by the air-fuel equivalence ratio.…”

This study was compiled from the results of various researches performed on usage diethyl ether as a fuel or fuel additive in diesel engines. Three different methods have been used the reduction of the harmful exhaust emissions of diesel engines. The first technique for the reduction of harmful emissions has improved the combustion by modification of engine design and fuel injection system, but this process is expensive and time-consuming. The second technique is the using various exhaust gas devices like catalytic converter and diesel particulate filter. However, the use of these devices affects negatively diesel engine performance. The final technique to reduce emissions and improve diesel engine performance is the use of various alternative fuels or fuel additives. The major pollutants of internal combustion engines are carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), particulate matter (PM) and smoke. The most researches declare that the best way to reduce is the use of various alternative fuels i.e. natural gas, biogas, biodiesel or using additives with alternative fuels or conventional fuels. Therefore, it is very important that the results of various studies on alternative fuels or fuel additives are evaluated together to practical applications. Especially, this study focuses on the usage of diethyl ether in diesel engines as fuel or fuel additive in various diesel engine fuels. This review study investigates the effects of diethyl ether additive on the CO emissions.

“…Compared with pure diesel fuel, the smoke emissions at full load are reduced up to 47.6%, while the concentration of particles decreases up to 43.79% with used blends. K. Lee investigated performance and emission characteristics of a DI diesel engine which operates with blended fuel (Lee, Kim, 2017). The obtained results show that blended fuel produced lower hydrocarbons (HC), carbon monoxide (CO) and particulate matter (PM) in comparison with pure diesel.…”

The paper presents two components of developed quasi-dimensional numerical model: spray package penetration and gas inflow from the zone without combustion into the spray packages. Correction of spray package penetration along the fuel spray radial axis is presented and described numerically. Numerical model simulation is validated in several measured operating points of direct injection diesel engine, after which the simulation results are presented. According to numerical model settings, each fuel spray was divided into packages (control volumes). In the same time interval, the shortest penetration was obtained for spray packages located at the fuel spray edge. Before reaching the break-up time spray package penetration was linear and after reaching the break-up time, package penetration had a curved form. Later injected spray packages quickly reached and surpassed earlier injected spray packages because earlier injected spray packages hit "gas wall" in the engine cylinder and they were "braked" with surrounding gas in comparison to packages injected later. Gas inflow from the zone without combustion into the spray packages is the most intensive for spray packages positioned at the fuel spray edge. The simulation shows that the inflow mass from the zone without combustion increases for spray packages injected later.
