A locomotive diesel engine, having a cylinder liner and a separate water jacket surrounding the cylinder liner, with a portion of the water jacket being positioned between the cylinder liner and the engine frame, where the cylinder liner is supported by the water jacket. An external shoulder on the cylinder liner can be supported by an internal flange in the water jacket, thereby eliminating direct contact between the cylinder liner and the engine frame. A coolant passage can be provided between the water jacket and the cylinder liner, at a point adjacent the topmost position of the top piston ring. An upper liner seal can be provided between the cylinder liner and the water jacket, above the coolant passage, and a lower liner seal can be provided between the cylinder liner and the engine frame, below the coolant passage. Coolant ports can be provided for coolant flow directly between the cylinder head and the water jacket, with seals in the coolant ports to seal the coolant, independently of the head gasket.

An enclosure for an energy storage device is presently disclosed. The enclosure includes a cell housing having a base portion and at least one side portion seamlessly extending from the base portion to define a volume and having a peripheral edge defining an aperture distal from the base portion through which an electrochemical cell may be disposed within the volume, and a cover securable to the peripheral edge of the housing, where the housing and cover are configured to house at least one electrochemical cell at an operating temperature greater than about 100 degrees Celsius. The enclosure may also include an environmental housing configured to nestingly receive the cell housing, and an insulating element disposed between the environmental housing and the cell housing. Also disclosed is a method of packaging the energy storage device utilizing the enclosure.

Methods and systems are provided for operating a vehicle including an engine comprising a turbocharger including a compressor and a turbine. The engine further includes a bypass path configured to selectively route gas from downstream of the compressor to upstream of the turbine. In one embodiment, the method comprises selectively increasing gas flow to the engine by adjusting gas flow through the bypass path from downstream of the compressor to upstream of the turbine. In this manner, the performance of the engine may be adjusted for various operating conditions.

An adaptive fuel limit function () for protecting an internal combustion engine. The adaptive fuel limit function is a learning function responsive to trends in an engine performance parameter such as compensated fuel consumption per unit of power produced (). The engine performance parameter is processed through a low pass filter () to allow changes in a fuel limit signal () in response to gradual changes in the fuel demand, such as may be due to wear in the engine, while blocking changes in the fuel limit signal in response to sudden changes in the fuel demand, such as may be due to a cylinder failure. The difference between the input and the output of the low pass filter may be processed to identify a failure level () for providing an alarm function distinct from the learning function.
