IMPROVED DIESEL ENGINE EFFICIENCY BY TIMING OF IGNITION AND COMBUSTION USING ULTRAVIOLET LIGHT

摘要

An exemplary embodiment of a UV light injector assembly is used to apply intense light that includes short wavelength UV to the interior of an engine cylinder near the desired time of fuel ignition. In an example embodiment, the light is produced by a short-arc xenon flash lamp. This flash lamp includes an integral reflector (e.g., a parabolic reflector) to collimate the majority of its light into parallel rays. The assembly includes a window for passing UV light into the cylinder. To direct the collimated rays of light from the flash lamp through the window a UV-transparent condensing lens is used to focus the light from the flash lamp onto the window.

1. A method, comprising:
introducing atomic oxygen and diesel fuel into a combustion chamber in a cylinder of a diesel engine, wherein the introduction is timed relative to a compression cycle of the cylinder to cause the diesel fuel to ignite with a crankshaft angle near a top of a compression stroke of a piston in the combustion chamber.
