... Abstract Conventional dual-fuel combustion (DFC) has been studied for decades due to its ability to produce high fuel conversion efficiency and its potential to defeat the well-known diesel NOx-PM trade-off. In DFC, a low-reactivity fuel (LRF) such as natural gas is premixed with air...

... Controlled Compression Ignition (RCCI) combustion. The experiments were conducted on a light-duty, single-cylinder diesel engine with a production GM/Isuzu engine head and piston and a retrofitted port fuel injection system. The global charge-mass equivalence ratio, ϕ′, was fixed at 0.32 throughout all...

... Opposed-piston two-stroke diesel engines have an inherent thermodynamic efficiency advantage and, by virtue of having double the firing frequency, allow for increased power density and lower NO X emissions while improving fuel efficiency, when compared to a four-stroke engine of equivalent...

... 10 03 2009 New diesel combustion modes face difficult challenges with respect to engine-out emissions and transient behavior. Transitions between lean conventional diesel combustion and lean, premixed, low-temperature diesel combustion are investigated with an automotive diesel engine...

... 19 11 2008 Derived from natural gas, coal, and even biomass Fischer-Tropsch (F-T) diesel fuels have a number of very desirable properties. The potential for emissions reduction with F-T diesel fuels in laboratory engine tests and on-road vehicle tests is well documented. While a number...

... 19 11 2008 In a swirl chamber type diesel engine, a strong swirl is produced inside the swirl chamber during the compression stroke. By spraying the fuel into this chamber and thus forming a good mixture, the engine can obtain excellent combustion even at high speeds. Therefore, swirl...
