  • Cast dual wall bulkhead with integral oil drain
    Patent number: 10578051
    Abstract: Systems and methods are provided for a cylinder block having one or more bulkheads. The bulkheads provide a dual-wall structure that may enhance the stiffness of the cylinder block in bending and torsion. The bulkheads may also provide an oil drain to allow oil to directly drain through a hollow core of the bulkhead. An overflow outlet may be formed in an inner wall of a bulkhead. In some implementations, a cylinder block with bulkheads may increase an oil capacity of an engine.
    Type: Grant
    Filed: November 16, 2017
    Date of Patent: March 3, 2020
    Assignee: Cummins IP, Inc.
    Inventors: Aaron S. Quinton, John Jerl Purcell, III, Nathaniel Hassall, Derek Ferguson

  • Seatless wet cylinder liner for internal combustion engine
    Patent number: 8978620
    Abstract: An apparatus includes an internal combustion engine with an engine block and a cylinder liner housing a piston. The engine block includes at least one cylinder cavity and at least one replaceable cylinder liner positioned within the cylinder cavity. At least two press fit areas create an interference fit between the engine block and the replaceable cylinder liner. One press fit area is located proximate to the top surface of the engine block and the other press fit area is located in the engine block at the opposite end of the cylinder liner. A storage volume is formed between the press fit areas by the outer surface of the cylinder liner and the surface of the engine block defining the cylinder cavity.
