Abstract
A device for monitoring an engine surface includes a fixture body defining a breather aperture. The fixture body includes a first face engageable with a surface of an engine cylinder bore. The first face defines a recess. The fixture body also includes a first end including a lip that engages with a cylinder block. The first end defines a first end aperture in fluid communication with the recess. The device also includes at least one biasing member coupled to the fixture body and configured to exert a force on the fixture body causing the first face of the fixture body to contact the surface of the cylinder bore.
Claims20
A device for monitoring an engine surface, the device comprising:
- a fixture body defining a breather aperture, the fixture body comprising:
- a first face engageable with a surface of an engine cylinder bore, the first face defining a recess, and
- a first end comprising a lip that engages with a cylinder block, the first end defining a first end aperture in fluid communication with the recess;
- and
- at least one biasing member coupled to the fixture body and configured to exert a force on the fixture body causing the first face of the fixture body to contact the surface of the engine cylinder bore.
A kit for analyzing a cylinder bore surface comprising,
- a first fixture body and a second fixture body, each of the first fixture body and the second fixture body defining a breather aperture, each of the first fixture body and the second fixture body comprising:
- a first face engageable with a surface of an engine cylinder bore, the first face defining a recess, and
- a first end comprising a lip that engages with a cylinder block, the first end defining a first end aperture in fluid communication with the recess;
- at least one biasing member extending between the first fixture body and the second fixture body, each of the at least one biasing member configured to exert a force on each of the first fixture body and the second fixture body, causing the first face of the first fixture body and the first face of the second fixture body to contact a surface of a cylinder bore when the kit is positioned within the cylinder bore.
A method of monitoring an engine surface, the method comprising:
- fixing a device to an engine cylinder bore such that a first face of the device is in contact with a surface of an engine cylinder bore, the first face defining a recess;
- providing a replication material to the recess such that the replication material contacts the surface of the engine cylinder bore, the replication material configured to cure after an amount of time has elapsed;
- removing the device including the cured replication material from the engine cylinder bore;
- and
- analyzing the cured replication material.
