    Abstract: An engine assembly and methods of supporting components of an engine assembly. An internal combustion engine includes an intake port. A charge air cooler is coupled to the intake port. A turbocharger including a charge air output port is fluidly coupled to the charge air cooler. A charge air tube is coupled to the charge air output port of the turbocharger. The charge air tube fluidly couples the turbocharger to the charge air cooler for transfer of compressed charge air from the turbocharger to the intake port of the internal combustion engine. A charge air tube support assembly is coupled to the charge air tube. The charge air tube support assembly is configured to allow axial displacement of the charge air tube along an axis of the charge air tube extending from the output port of the turbocharger to the charge air cooler in response to thermal expansion of the charge air tube. The charge air tube support assembly comprises a wear sleeve and a clamp.

    Abstract: A system and method for fluidly sealing a cylinder head interface between an engine block and a cylinder head of an internal combustion engine. An example apparatus includes a perimeter seal disposed on an outer periphery of the cylinder head. The perimeter seal has a first surface to abut a cylinder head sealing surface and a second surface to abut an engine block sealing surface. The perimeter seal is configured to prevent fluid from an external environment from entering the cylinder head interface and to allow fluid within the cylinder head interface to vent to the external environment when the fluid is above a predetermined pressure. A first fluid transfer tube seal fluidly seals a first fluid transfer orifice extending between the engine block and the cylinder head. The perimeter seal and the first fluid transfer tube seal are formed as a unitary structure.

    Abstract: A turbocharged internal combustion engine system includes at least one high pressure turbocharger system and at least one low pressure turbocharger system. An air-to-air intercooler is connected between the low pressure compressor of the low pressure turbocharger system and the high pressure compressor of the high pressure turbocharger system. An air-to-water aftercooler is connected to the intake system between the high pressure compressors and the intakes of the cylinders of the internal combustion engine.

    Abstract: A fuel filtration system and methods controlling, and operating a fuel filtration system. A first fuel filter head is fluidly coupled to one or more first fuel filters, a second fuel filter head is fluidly coupled to one or more second fuel filters and a selector valve is coupled to the first fuel filter head and the second fuel filter head. The selector valve includes a primary valve inlet port, a primary valve outlet port, and a movable valve body movable from a first position to a second position. The first position fluidly couples the first fuel filter head to the primary valve outlet port and fluidly decouples the second fuel filter head from the primary valve outlet port. The second position fluidly couples the second fuel filter head to the primary valve outlet port and fluidly decouples the first fuel filter head from the primary valve outlet port.
