ABSTRACT:
The present disclosure provides an internal combustion engine having an engine housing with at least one cylinder that has diameter less than about 3 inches. A fuel injector is provided and disposed at least partially within the at least one cylinder, and includes a plurality of outlet orifices having a diameter between about 50 microns and about 110 microns. The disclosure further provides a method of operating an internal combustion engine. The method includes the steps of rotating an engine crank shaft of the engine at a speed greater than about 5000 revolutions per minute, injecting a quantity of fuel into each of the cylinders, and burning at least every fourth piston stroke a sufficient quantity of the injected fuel to yield a brake mean effective pressure of at least about 200 lbs. per square inch.
