Problems solved by technology

However, this method requires the use of an EGR system and does not take into account the age of the engine or engine souping during long idle periods
Therefore, there is a fuel consumption penalty associated with this exhaust port heating method

Embodiment Construction

[0015] An engine may have a lubrication system that provides oil for lubricating the valve train, pistons, and other related engine components. During engine operation, unburned oil and / or fuel may accumulate in the engine exhaust manifold. The lubrication system may interact with the engine controlled by the engine control system to burn off unburned oil and / or fuel to reduce fouling of the engine exhaust system. refer to figure 1 An example of such a configuration is shown in which a lubrication system interacts with a locomotive engine to provide lubrication during engine operation, and an engine controller enables periodic exhaust maintenance.

[0016] In one embodiment, the engine controller can switch the engine between different operating modes. Examples of operating modes may include normal operating mode, low load, high load, high heat mode, startup mode, limited oxygen mode, and the like. Under normal operating conditions, the oil used to lubricate the pistons is ...

Abstract

Methods and systems are provided for an engine. The internal combustion engine has a plurality of cylinders that utilize oil for lubrication purposes. In one embodiment, a system includes a high speed diesel engine having cylinders in banks, each cylinder having at least one port, and a controller configured to operate the engine in at least two modes, with at least one mode being a port heating mode. The controller is configured to vary the port heating mode based on at least one of a function of time, engine age, and a measured or calculated megawatt hours of the engine, so that the variation decreases for the port heating mode, based on one or more of: frequency of port heating events, duration of a port heating event, target temperature of a port heating event, and amount of fuel used by at least one of the cylinders during a port heating event.

Description

[0001] priority claim [0002] This application claims priority from Indian Application No. 202041031788 filed on 24 July 2020. technical field [0003] Embodiments of the subject matter disclosed herein relate to internal combustion engines, and more particularly to heating cylinder exhaust ports. Background technique [0004] Various engines may have lubrication systems in which pressurized oil may be used to lubricate and / or cool engine valve train components, camshaft assemblies, pistons, and related engine components. Such an oil system provides enough oil to lubricate and cool the engine under full load. [0005] In some engines, such as large bore engines designed to run heavily at full load, oil from the lubrication system may become lodged in grooves in the cylinder walls and end up in the exhaust system or the engine stack (enginestack). Especially under low load conditions, the unburned fuel produced by combustion can lead to the accumulation and deposition of u...
