The Invention
UW-Madison researchers have developed advanced fuel ignition technologies for use in flexible and fuel agnostic combustion engines. The technology employs a secondary "pilot" injector directing a fuel stream over an igniter, such as a glow plug, to create a pilot flame igniting fuel from a primary “main” injector. An engine employing this approach can work with different quality fuels including low cetane number fuels with a wide range of properties and more generally can substantially reduce soot, carbon monoxide, and hydrocarbon emissions. The ability to place the igniter and pilot injector off-center from the cylinder axis allows this design to be readily incorporated into existing engine designs where the cylinder head is crowded with valve openings and the main injector.
