Support bracket

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

Various systems and methods are provided for utilizing a crankshaft lip seal over the course of a first overhaul life and a second overhaul life. In one example, a method includes installing the crankshaft lip seal between a flywheel housing and a crankshaft of an engine and operating the engine with the crankshaft lip seal. The method further includes removing the crankshaft lip seal, re-machining a floating seal sleeve coupled to the crankshaft or the flywheel housing, and replacing a lip. The crankshaft lip seal is then re-installed between the flywheel housing and the crankshaft and the engine operated with the re-installed crankshaft lip seal.

Multi-position crankshaft lip seal

Forward end housing

Systems are provided for a mounting assembly providing structural support to a pair of turbocharger and charge air coolers. In one example, the mounting assembly may include support brackets and pedestals for coupling the turbochargers and the charge air coolers to one structure. Separate channels for applying lubricant and coolant to the turbochargers and the charge air coolers may be coupled to the mounting assembly.

Turbocharger support system

Various methods and systems are provided for an intake manifold for an engine. In one example, the intake manifold comprises a first passage for supplying intake air to a plurality of cylinders of the engine and a second passage for supplying gaseous fuel to the plurality of cylinders.

Multi-fuel engine system

Various methods and systems are provided for an intake manifold for an engine. In one example, an insert comprises an annular body having a top surface, bottom surface, inner surface, and outer surface. The insert further comprises a first groove for coupling an intake air port of an intake manifold to a cylinder head, a second groove for circulating gaseous fuel received from a gas runner of the intake manifold, and one or more openings to fluidically couple the second groove to an interior of the intake air port. The insert is configured to mix gaseous fuel and intake air at a coupling location between the intake manifold and the cylinder head.

Various methods and systems are provided for regenerating an exhaust gas recirculation cooler. One example method includes, initiating an EGR cooler regeneration mode, wherein the EGR cooler regeneration mode comprises changing a fuel distribution of a donor cylinder group relative to a non-donor cylinder group of an engine, and increasing at least one of engine speed or load of the engine.

Methods and systems for exhaust gas recirculation cooler regeneration

In accordance with the embodiments of the present invention, an engine is disclosed. The engine includes at least one donor cylinder and at least one non-donor cylinder coupled to an intake manifold feeding intake air and an exhaust manifold. The exhaust manifold is configured to carry an engine exhaust emission from the donor cylinder and the non-donor cylinder. The engine also includes an exhaust gas recirculation manifold extending from the donor cylinder to the intake manifold for recirculating a donor cylinder exhaust emission from the donor cylinder to the donor, and non-donor cylinders via the intake manifold. The engine further includes an after-treatment system and a sensor configured to sense a temperature of the engine exhaust emission and a device configured to receive a sensing signal from the sensor and to control a parameter of the engine and a component of the engine in response to the sensing signal.

Engine utilizing a plurality of control valves, and a related method thereof

Various methods and systems are provided for operating an internal combustion engine, the engine having a plurality of cylinders including one or more donor cylinders and one or more non-donor cylinders. In one example, a method includes, during an exhaust gas recirculation cooler heating mode, operating at least one of the donor cylinders at a cylinder load sufficient to increase an exhaust temperature for regenerating an exhaust gas recirculation cooler, and operating at least one of the non-donor cylinders in a low- or no-fuel mode.

Methods and systems for operating an engine

Fuel pump mounting structure

Methods and systems are provided for operating an internal combustion engine having an exhaust system and a plurality of cylinders that utilize fuel and/or oil for combustion and engine lubrication purposes. In one example, a method comprises, while the engine is operating in a low-load mode or an idle mode, successively operating distinct subsets of said cylinders at a cylinder load sufficient to increase an exhaust temperature for burning unburned fuel and/or oil deposited in the cylinders or engine exhaust system. Herein, each successively operated subset comprises at least one but fewer than all of the plurality of cylinders, and the cylinders that are not currently being operated in a subset are operated in a low- or no-fuel mode.
