Problems solved by technology

As an example, including a single channel with one inlet and one outlet in an aperture bridge may not provide adequate cooling for all engine types and modes of operation
Furthermore, while positioning the cross-drilled channels in Williams' bridges may sufficiently cool the deck face at the bridges, the inventors herein have realized that there may be additional deck faces within the bridges below the deck face. hot spots, and cooling channels positioned to cool the top surface may not adequately cool these additional hot spots
Further, using two separate cooling systems (water to oil) can be complex, expensive and not suitable for all engine types

Embodiment Construction

[0021] figure 1 A schematic diagram of a vehicle system 6 is shown. Vehicle system 6 includes engine system 8 coupled to exhaust aftertreatment system 22 . Engine system 8 may include engine 10 having a plurality of cylinders 30 . Engine 10 includes an engine intake 23 and an engine exhaust 25 . Engine intake 23 includes throttle 62 fluidly coupled to engine intake manifold 44 via intake passage 42 . The engine exhaust 25 includes an exhaust manifold 48 that ultimately leads to an exhaust passage 35 that directs exhaust gas to the atmosphere. Throttle 62 may be located downstream of a boosting device, such as turbocharger 50 or a supercharger, in intake passage 42 .

[0022] Turbocharger 50 may include a compressor 52 disposed between intake passage 42 and intake manifold 44 . Compressor 52 may be at least partially powered by exhaust turbine 54 disposed between exhaust manifold 48 and exhaust passage 35 . Compressor 52 may be coupled to exhaust turbine 54 via shaft 56 ....

Abstract

The present disclosure provides a "hole bridge cooling channel". The present disclosure provides a system for cooling a cylinder block via a bore bridge cooling passage. In one example, a cylinder block having a bore bridge positioned between a first cylinder and a second cylinder has at least one cooling passage positioned within the bore bridge, the cylinder block further including a coolant jacket at least partially surrounding the first cylinder and the second cylinder. An inlet of the at least one cooling channel has an area greater than an outlet of the at least one cooling channel, and at least a portion of the at least one cooling channel has a non-cylindrical geometry formed by the indwelling core.

Description

technical field [0001] This description generally relates to cylinder blocks and cooling passages within the cylinder blocks. Background technique [0002] Engine systems typically include a cylinder block with an attached cylinder head that includes a series of cylinders with surrounding material for attaching various components. The cylinder block and cylinder head also include a cooling system that includes a plurality of cooling passages surrounding the cylinder. Coolant (such as water, oil, glycol, etc.) may be pumped or otherwise sent through cooling passages to remove heat from the cylinder block and cylinder head via heat exchange. However, cooling the bore bridges (which are the areas between adjacent cylinders) on the cylinder block and / or cylinder head can be challenging. Via bridges are stressed areas that have little packaging space and are exposed to a lot of heat. If the bore bridges are not sufficiently cooled, cylinder bore deformation, cylinder liner det...
