    • 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 125 microns, or about 0.05 millimeters and about 0.125 millimeters. The injector may include more than one set of separately controllable fuel outlet orifices, at least one of which could have an average diameter between about 0.05 millimeters and about 0.125 millimeters. 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.
    • 本公开提供了一种具有发动机壳体的内燃机,该发动机壳体具有直径小于约3英寸的至少一个气缸。 提供燃料喷射器并且至少部分地设置在所述至少一个气缸内,并且包括多个直径为约50微米至约125微米,或约0.05毫米和约0.125毫米的出口孔。 喷射器可以包括多于一组可单独控制的燃料出口孔口,其中至少一个可具有约0.05毫米至约0.125毫米的平均直径。 本公开还提供了一种操作内燃机的方法。 该方法包括以大于每分钟5000转的速度旋转发动机的发动机曲轴的步骤,将一定数量的燃料喷射到每个气缸中,并且至少在每四冲程冲程中燃烧足够量的喷射 燃料产生制动平均有效压力至少约为200磅。 每平方英寸
