    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.

    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.
