A crankshaft for an internal combustion engine is provided and may include crank pins, crank journals, and webs extending between the crank pins and the crank journals. Each web further may include a web surface on each side of the web. On the web surface, a repair region is provided with an undercut formed in the web. Included in the crankshaft is a cladding deposit that is fused to the web surface in the repair region of the crankshaft.

Crankshaft repair system and method

Systems and methods for intermittent supply of lubricating oil to a tip of a rocker arm assembly. In one embodiment, a lubricating oil may be selectively to a tip of a rocker arm via oil channels aligned only during opening of a valve coupled to the tip.

Systems and methods for rocker arm lubrication

A system and method are provided for an internal combustion engine. An engine system, in one example, includes a cylinder liner positioned within an opening of a crankcase, including a surface biasing a landing surface of an undercut fillet of the crankcase, and including a cylinder opening and a seal arranged in a groove of the cylinder liner positioned axially above the undercut fillet. The engine system further includes a fluid gasket and a combustion gasket positioned between a cylinder head and the crankcase, the fluid gasket and the combustion gasket being decoupled from one another.

Internal combustion engine system

Systems and methods for supplying lubricating oil to a high-pressure fuel pump of an engine fuel system. In one embodiment, a system may include a plurality of channels routing lubricating oil to a gear system and drive shaft of a pump without flowing an entire volume of the lubricating oil through a cavity of the drive shaft.

System and method for oil supply to pump

An insert device includes a first coupling body inserted into an engine cylinder head. The first coupling body extends around a center axis to define a first interior volume of the first coupling body that is shaped to receive a distal tip of a fuel injector. The insert device includes a second mixing body coupled with the first coupling body and extending around the center axis. The second mixing body includes conduits that receive fuel from the fuel injector and air from a combustion chamber, combine the fuel with the air, and direct the fuel-air mixture into the combustion chamber. The first coupling body has a first end surface positioned to face the cylinder head and the first coupling body is tapered such that an outer diameter of the first coupling body is larger toward the first end surface than toward the second mixing body.

Insert device for fuel injection

A fuel and gas mixing structure for an engine is provided. This mixing structure includes a body configured to be positioned between a fuel injector and a cylinder of an engine. The body defines an interior volume that is configured to receive gas (e.g., air) from outside the body and to receive one or more streams of fuel from the fuel injector in the interior volume. The body also includes one or more upper channels and one or more lower channels that are configured to provide a substantially similar amount of flow relative to each other to the interior volume The body also defines one or more mixture conduits configured to conduct plumes of the fuel and gas, while mixing, from the interior volume to one or more exit ports and therethrough to the cylinder.

Engine mixing structures

A fuel and gas mixing structure for an engine is provided. This mixing structure includes a body configured to be positioned between a fuel injector and a cylinder of an engine. The body defines an interior volume that is configured to receive gas from outside the body and to receive one or more streams of fuel from the fuel injector in the interior volume. The body also defines one or more mixture conduits configured to conduct plumes of the fuel and gas, while mixing, from the interior volume to one or more exit ports and therethrough to the cylinder.

Modular cam shaft

Various methods and systems are provided for an exhaust gas recirculation cooler including a plurality of cooling tubes. In one example, an exhaust gas recirculation (EGR) cooler includes a plurality of cooling tubes positioned within a housing of the EGR cooler, each cooling tube of the plurality of cooling tubes extending between and directly coupled to tube sheets of the EGR cooler at ends of each cooling tube, where at least one end of one or more cooling tubes of a first portion of the plurality of cooling tubes, inward of a tube sheet coupled to the at least one end, includes a compliant region, where the first portion is positioned proximate to an exhaust inlet of the EGR cooler.

Method and systems for an EGR cooler including cooling tubes with a compliant region

Various methods and systems are provided for an exhaust gas recirculation system. In one example, an exhaust gas recirculation cooler includes a first section, arranged proximate to an exhaust gas inlet of the EGR cooler and including a first plurality of tubes and a first plurality of fins coupled to the first plurality of tubes, where at least one of the first plurality of tubes and the first plurality of fins are comprised of a first material that has a first coefficient of thermal expansion (CTE); and a second section, arranged downstream of the first section and including a second plurality of tubes and a second plurality of fins coupled to the second plurality of tubes, where the second plurality of tubes and the second plurality of fins are comprised of a second material that has a second CTE, the second CTE greater than the first CTE.

Exhaust gas recirculation system and method

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.

Method and system for controlling engine performance

An exhaust casing for use with a turbocharger includes a hollow body that has two mutually opposed large walls, which extend along first and second major dimensions of the hollow body and are spaced apart by a minor dimension of the hollow body, the hollow body defining a plenum and an inlet nozzle opening into the plenum along the minor dimension of the hollow body. The casing further includes an outlet nozzle opening from the plenum along one of the major dimensions of the hollow body.
