“…Split injection may be a possible solution to DFLTC's cyclic combustion variations problem at low loads; however, there is still the issue of possible soot formation, or particulate matter (PM), with near-TDC second injection of diesel. The use of oxymethylene ether (OME) fuel blends has garnered increasing research interest to mitigate PM emissions [32][33][34][35][36][37][38]. Being oxygenated fuels with fewer (or no) carbon-carbon bonds, OMEs can help reduce PM emissions [35].…”

“…The well-to-wheel CO 2 analysis showed that the use of an optimized series hybrid architecture along with OME-gasoline dual-fuel combustion improves upon current commercial trucks by 25%. Garcia et al [37] demonstrated the use of OME fuels in a four-cylinder 1.6 L engine. The engine was fueled with three different fuel blends, each with a different amount of OME fuel and Fischer-Tropsch diesel on a volume basis; three different speed/load points were considered for the study.…”

Dual-fuel low-temperature combustion is a possible solution for alleviating the tradeoff between oxides of nitrogen and soot emissions in conventional diesel combustion, albeit with poor combustion stability, high carbon monoxide, and unburned hydrocarbon emissions at low engine loads. The present work compares emissions and combustion (heat release and other metrics) of both diesel and poly-oxy methylene dimethyl ether as high-reactivity fuels to ignite natural gas while leveraging spray-targeted reactivity stratification, which involved multiple injections of the high-reactivity fuels. The experiments included six parametric sweeps of: (1) start of first injection, (2) start of second injection, (3) percentage of energy substitution of natural gas, (4) commanded injection duration ratio, (5) rail pressure, and (6) intake pressure. The experiments were performed on a 1.8 L heavy-duty single-cylinder research engine operating at a medium speed of 1339 rev/min. Not-to-exceed limits for the indicated oxides of nitrogen emissions, maximum pressure rise rate, and the coefficient of variation of the indicated mean effective pressure were set to 1 g/kWh, 10 bar/CAD, and 10%, respectively. The indicated emissions decreased and combustion improved significantly for both fueling combinations when the experimental procedure was applied.

“…Methanol (and other short-chain alcohols) lubricity is extremely low, and the fuel can cause corrosion on metal components. Researchers that have used methanol as a fuel (like in previous work by the author [97], Shamun et al [98] and Aziz et al [99]) use additive like Infineum R566 and VpCI®-706 to try to improve the lubricity and prevent the corrosion. As methanol is severely lacking in these two aspects the quantity of both additives should be used in relatively high quantities from 200 to 300 ppm (parts per million) by mass.…”

My parents, Erika and Franzel, for their support and caring. Here's to seeing each other more often and enjoying our time together. To my brother, Daniel, for your easygoing self which contrasts my perpetual stress. I will always be there for you.My official advisors Antonio García and David Villalta, and the unofficial advisor Javier Monsalve-Serrano. For the education on combustion, engines, research, and academia. Also, the professional and personal growth you helped me achieve. I will carry on the lessons you taught me through the years. The colleagues that have become friends and animate office work, Álvaro, Erasmo, Carlos, Diego and Imad; and the ones that raised the bar, "Rafa" and "Santi".CMT-Motores Térmicos and the combustion department, for the opportunity of joining this research group and developing this investigation. To the secretary, in particular Amparo Cutillas, for being more aware than anybody about what and when documentation was needed at every stage of the process. To "Dani", Hector and all the amazing technicians for being pivotal in the development of this work. Thanks for making testing so entertaining.
