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.

Abstract: A rapid compression device for use in initiating combustion within an internal combustion engine is disclosed. The rapid compression device employs a prechamber adapted to be in fluid communication with a main combustion chamber of the internal combustion engine. A piston is provided within a cylinder of the prechamber and compresses natural gas therein to a degree sufficient to auto-ignite the gas when mixed with air. The auto-ignition of the gas and air mixture results in combustion gases which are communicated to the main combustion chamber for ignition of the air and gas mixture provided therein as well.

Abstract: The present invention relates generally to the field of homogeneous charge compression engines. In these engines, fuel is injected upstream or directly into the cylinder when the power piston is relatively close to its bottom dead center position. The fuel mixes with air in the cylinder as the power piston advances to create a relatively lean homogeneous mixture that preferably ignites when the power piston is relatively close to the top dead center position. However, if the ignition event occurs either earlier or later than desired, lowered performance, engine misfire, or even engine damage, can result. Thus, the present invention divides the homogeneous charge between a controlled volume higher compression space and a lower compression space to better control the start of ignition.
