  • Patent number: 11028800
    Abstract: Methods and systems are provided for a coolant system coupled to cylinders in a locomotive engine. In one example, a coolant system coupled to an individual cylinder may include a cylinder liner jacket encircling the cylinder, a cylinder head lower coolant jacket surrounding a lower surface of a cylinder head placed over the cylinder, a cylinder head upper coolant jacket surrounding an upper surface of the cylinder head, and a cylinder head exhaust port cooling jacket surrounding an exhaust port of the cylinder. Coolant may flow to each of the cooling jackets from a coolant feed gallery located in the engine crankcase, and after flowing through the engine, the coolant may return to a coolant return gallery also located in the engine crankcase.
    Type: Grant

  • Patent number: 9790869
    Abstract: Various methods and systems are provided for a multi-fuel capable engine. In one example, a system comprises an engine having at least one cylinder controlled via an intake valve, a first fuel system to deliver liquid fuel and a second fuel system to deliver gaseous fuel to the at least one cylinder, a variable valve timing actuation system to adjust one or more of an opening or a closing timing of the intake valve, and a controller. The controller is configured to, during a liquid fuel only mode, adjust the variable valve timing actuation system to close the intake valve at a first timing based at least on engine load, and during a multi-fuel mode, adjust the variable valve timing actuation system to close the intake valve at a second timing.

  • Patent number: 8919311
    Abstract: Various methods and systems are provided for varying valve timing in a V-engine. In one embodiment, a method for an engine comprises pivoting a first cam follower for a first cylinder of a first bank and a second cam follower for a second cylinder of a second bank about a rotatable pivot shaft, driving the first cam follower and the second cam follower with a camshaft to operate a respective first valve of the first cylinder and a second valve of the second cylinder, and rotating the pivot shaft to vary a valve timing of the first cylinder and the second cylinder.
