摘要:
Improved internal combustion engine, particularly, an improved two-stroke, diesel aircraft engine. The invention includes a new wrist pin/connecting rod connection (46,66,62), a new cooling system for fuel injectors (110), a new cylinder head cooling arrangement (154), a new cooling jacket cross-feed arrangement, and a new combustion seal arrangement (338). A bypass fuel line (146) communicates between the fuel pump and a cooling fuel inlet port on an injector, such that overflow fuel from the fuel pump flows through the injector, thereby cooling it.

A piston for an internal combustion engine, the engine having a connecting rod coupled to a wristpin, the wristpin being connected to the piston for pivotal movement about an axis, the piston comprising: a top portion and a generally cylindrically-shaped wall portion extending from the top portion, the top and wall portions defining a skirt cavity, the top portion having thereon a downwardly extending projection with a downwardly facing bearing surface for the wristpin, the bearing surface extending in the direction of the axis and defining a portion of a cylinder centered on the axis, and the projection having opposite sides facing the skirt cavity; at least one lubricant passage extending through the projection from one of the opposite sides and over the bearing surface to the other of the opposite sides; and a lubricant opening communicating between the lubricant passage and the bearing surface to supply lubricant to the bearing surface and to the wristpin.

A single input engine controller and system are provided for translating a single input indicative of the amount of fuel to be supplied to an engine from a fuel control interface into separate signals for controlling the amount of fuel supplied to the engine and the RPM of a propeller powered by that engine. The single input controller translating the single input into the separate signal for the RPM of the propeller according to a fuel efficiency relationship between the fuel amount and the propeller RPM.
摘要:
An internal combustion engine that includes a crankcase having a crankcase pressure defined within the crankcase relative to an ambient pressure. The crankcase pressure varies in response to operation of the internal combustion engine. A crankcase pressure regulator is in fluid communication with the crankcase, and the crankcase pressure regulator includes a first passageway defining a first flow path, a second passageway defining a second flow path in a parallel arrangement to the first passageway. When the crankcase pressure is less than a first predetermined pressure, the first valve moves to the open position to allow a fluid flow into the crankcase through the first passageway. When the crankcase pressure is greater than a second predetermined pressure, the second valve moves from the closed position to the open position to allow a fluid flow from the crankcase through the second passageway.
