Abstract
Official abstract text for this publication.
A gaseous fuel engine combines the efficiencies associated with high compression ratio engines with the attractiveness of fueling with natural gas. Each engine cylinder has an associated fuel injector positioned for direct injection and supplied with gaseous fuel from a high pressure common rail. A separate ignition prechamber is also supplied with natural gas and includes an ignition device. Hot gas generated by igniting a mixture of gaseous fuel and air in the prechamber are used to ignite a much larger charge of gaseous fuel injected into the engine cylinder from the fuel injector. The engine has a compression ratio greater than 14: to 1.
First claim
Opening claim text (preview).
What is claimed is: 1. An engine comprising an engine housing that defines a plurality of cylinders; a plurality of pistons, each respectively positioned in one of the cylinders, and being movable between a bottom dead center position and a top dead center position that define a compression ratio greater than 14:1; a plurality of fuel injectors, each respectively positioned for direct injection into one of the cylinders; a plurality of ignition prechambers disposed in the eng…
