Effects of injection timing on bio-diesel fuelled engine characteristics—An overview

Effect of Adding RON97 Into Waste Cooking Oil as an Alternative Fuel for Diesel Engine

“…Additionally, the proportion of WCO is higher in W90R10, which relatively has a higher oxygen content than W85R15 and W75R25. The presence of oxygen content in the molecular chain of the vegetable oils helps the combustion process as acknowledged by many researchers and this research also proves the contribution of the oxygen content [11,12].

Effect of biodiesel on diesel engine emissions

“…For different engines and different testing conditions, biodiesel of various origin and different biodiesel/diesel mixtures, NO x emission can be lower for around 20% but also higher for around 26% [49], or as in [37] lower for 26%, or higher for around 14% when using biodiesel instead of diesel fuel. The increase in NO x emission is present in the research results in [35,36,[42][43][44][45]60], while the papers [21,32,38,55] show the increase of NO x emission of 5%, 10%, 15%, and 16 %, respectively, when biodiesel is substituted for diesel fuel. When using B30, NO x emission is higher in lower engine operation modes (around 8%) than in higher modes (around 1%), compared with the engine running on diesel fuel [53].…”

“…However, it is possible to find the optimal pre-injection time so that the effective power, effective specific fuel consumption, exhaust gases temperature, pressures in cylinders and other important characteristics of engine operation can be at an acceptable level when using B100 compared with diesel [39]. The research [8,14,31,[40][41][42][43][44][45][46] shows that from the aspect of using biodiesel as a Diesel engine fuel and the effects on engine operation, it is important that processes that take place in the fuel supply systems, injection and mixture formation processes, as well as knowledge of biodiesel characteristics that are not prescribed by standards (speed of sound, bulk modulus, surface stress, etc.) are fully studied and clear.…”

“…The research conducted in this direction [13,15,17,18,34,36,37,39,42,43,[47][48][49][50][51][52][53] undoubtedly points to the important smoke reduction in exhaust gases when using biodiesel compared with diesel fuel. The reduction is mentioned as significant in all of the conclusions of the previous studies and it ranges from 35% [37] to 72% [49] when using B100 compared with diesel fuel.…”

A miniaturized electronic sensor for instant monitoring of ethanol in gasohol fuel blends

“…7 Binary gasoline-ethanol blends, oen termed as gasohol, have been formed by mixing #10% by volume anhydrous ethanol in gasoline and have been used as transportation fuel, recognized as E10. [8][9][10] It is unusual for an alternative fuel, but ethanol has been reported to potentially enhance the efficiency and performance of internal combustion engines. 11,12 Table 1 shows the physicochemical properties [13][14][15][16][17][18][19][20] of gasoline, ethanol, and gasohol (E10) blended fuel.…”
