Abstract: A cooling system for an internal combustion engine according to the principles of the present disclosure includes an engine block, a compression device, a cooling circuit, a first pump, and a fuel delivery device. The engine block at least partially defines a combustion chamber and a cooling passage. The cooling passage extends through the engine block. The compression device is received in the engine block to partially define the combustion chamber. The compression device is movable within and relative to the engine block. The cooling circuit is in fluid communication with the cooling passage. The first pump is in fluid communication with the cooling circuit and is configured to circulate a fuel through the cooling circuit and the cooling passage. The fuel delivery device is in fluid communication with the cooling circuit and is configured to deliver the fuel to the combustion chamber.

Abstract: A powertrain system is provided and may include a combustion engine, a crankshaft, and a turbo-compounding system. The combustion engine may include an intake manifold and an exhaust manifold. The crankshaft may be driven by the engine. The turbo-compounding system may be configured to drive the crankshaft and may include a first turbine and a drive system. The first turbine may include an inlet fluidly communicating with the exhaust manifold. The drive system may include an input shaft driven by the first turbine, and an output shaft engaged with the crankshaft. The drive system may be configured to drive the output shaft at more than one drive ratio relative to the input shaft.

Abstract: A cylinder liner with improved cooling and strength is disclosed. The cylinder liner includes a liner wall extending annularly about a piston bore. The liner wall has an inner face adjacent the piston bore and an outer face oppositely arranged relative to the inner face. The outer face includes a water jacket surface that is co-extensive with at least part of the outer face. A plurality of indentations are disposed along the water jacket surface of the liner wall. The plurality of indentations extend radially inwardly from the water jacket surface to define corresponding areas in the liner wall of compacted material. Accordingly, the plurality of indentations increase surface area of the water jacket surface to improve heat transfer away from the liner wall while also increasing hoop strength of the liner wall.
