... variations in dual fuel combustion are analyzed, comparing diesel – natural gas (NG) and polyoxymethylene dimethyl ether (POMDME) – NG dual fuel combustion. Cyclic variability was initially quantified using the coefficient of variation (COV) of IMEPg computed from experimental cylinder pressure data...

... by no later than 2050. To accomplish this, engines with near zero GHG emissions must be developed now. In addition to new ships, there is a large existing fleet of diesel fueled engines in the market today which are candidates for retrofit. Ammonia fueling of a diesel engine using dual-fuel combustion...

... Dual fuel engines offer the potential for considerable reductions in emissions of carbon dioxide (CO 2 ), as well as reducing emissions of particulate matter (PM). However, the combustion processes occurring inside a dual fuel engine are complex. This is due to the ignition of a homogeneous lean...
