This debris and the resulting wear can eventually lead to early engine failure
[0003] Engine manufacturers may or may not have specialized equipment for cleaning engine blocks; however, smaller manufacturers and / or groups such as suppliers that provide engine blocks to end users or may sell or rebuild engines Other aspects of the cylinder block may not be accessible to required cleaning equipment
Thus, at least in some cases, it is difficult to ensure the cleanliness of the engine block

Embodiment Construction
[0019] figure 1 An exemplary embodiment of an engine block 10 is shown generally in . The engine block 10 may be constructed, for example, of cast iron or alternatively of aluminum or magnesium or any other desired material, and may include one or more cylindrical bores for receiving an internal combustion engine such as a compression ignition engine or a spark ignition engine the piston. It should be appreciated that such an internal combustion engine including engine block 10 may be used to power on-highway or off-highway machines, stationary equipment, or any other known machine or vehicle.
[0020] Engine block 10 may be a one-piece or multi-piece casting and may generally include an upper section 12 and a lower section 14 . The upper section 12 may include a plurality of cylinder bores 16 formed within the engine block 10 and openings through a roof 18 of the engine block 10 . Although sixteen cylinder bores 16 are shown, it should be appreciated that the engine block ...

The invention relates to a system and method for measuring cleanliness of an engine cylinder block. The system for measuring cleanliness of an engine cylinder block includes a set of fittings configured for receipt at least partially within oil passage openings of a lubrication system of the engine cylinder block. Each of the fittings includes a fluid collection passage therethrough. The cleanliness measuring system also includes a set of fluid sampling bottles configured for attachment to the fittings. In an attached configuration of the cleanliness measuring system, each of the fluid sampling bottles is attached to one of the fittings and the fittings are secured within one of the oil passage openings, a fluid is introduced into the lubrication system, the fluid and any debris carried bythe fluid from within oil passages of the engine cylinder block flow into the fluid sampling bottles, and debris collected in the fluid sampling bottles is measured to determine a cleanliness level of the engine cylinder block.
Description
technical field [0001] The present invention relates generally to a system and method for measuring the cleanliness of an engine block, and more particularly to collecting and measuring debris carried by fluid trapped within fluid sampling bottles using fittings Locates in the oil passages of the engine block. Background technique [0002] Even if the engine block is new and appears to be ready for use, it is important to ensure that the engine block, including the various passages running through it, are clean. Any debris pieces, even of the smallest size, that are introduced into the engine block prior to use, for example during manufacture or assembly, can scratch inner surfaces such as cylinder and / or oil passage walls and / or outer surfaces of reciprocating components. This debris and the resulting wear can eventually lead to early engine failure. [0003] Engine manufacturers may or may not have specialized equipment for cleaning engine blocks; however, smaller manufa...
