Abstract: An engine lubrication system simulating device is provided, having a reservoir configured to contain engine oil. The simulating device may also include an agitation device configured to agitate oil in the reservoir. In addition, the simulating device may include a circulation system configured to circulate oil between the reservoir and a reserve tank of an oil consumption measuring device and maintain a constant level of oil in the reservoir. Further, the simulating device may include an output port configured to facilitate removal of oil from the reservoir at a known, controlled rate and transport it to a location separate from the reservoir and the oil consumption measuring device.

Abstract: Carbon deposits on engine components can negatively affect engine performance. An engine of the present disclosure includes at least one carbon deposit resistant engine component attached to an engine housing. The engine component includes at least one relatively high surface tension surface that is a non-contact wear surface and to which a relatively low surface tension coating is attached. The relatively low surface tension coating has a surface tension at least one of equal to and less than 30 dyne/cm.
