Internal Combustion Test Engine With System And Method For Adjusting Cylinder Offset

摘要

A set of mechanisms, for use with an internal combustion test engine, for testing cylinder offset during operation of the engine. The test engine specifics may vary, but it is assumed to have a crankcase base that supports a cylinder barrel and cylinder head. During engine operation, a transit plate is secured to the top surface of the crankshaft base, and a pair of wedge plates is secured between the transit plate and the bottom of the cylinder barrel. When the engine is not in operation, the transit plate can be slid in a direction normal to the crankshaft axis (for cylinder offset adjustment), and the wedge plates can be moved relative to each other (for cylinder height adjustment).

主权项

1. A test engine for testing cylinder offset during operation of an internal combustion cylinder, comprising:
a crankcase base; a cylinder barrel having a cylinder bore and having a cylinder barrel flange around the cylinder bore; a cylinder head mounted above the cylinder barrel; a crankshaft supported within the crankcase base, the crankshaft having a connecting rod and piston; wherein the crankcase base has an opening in its top surface for receiving the cylinder bore; a transit plate interposed between the barrel flange and the top of the crankcase base, and having an opening for receiving the cylinder bore; wherein the transit plate is configured to be fixedly attached to the crankshaft base and cylinder barrel during operation of the test engine, but slideably moveable across the top of the crankcase base in a direction normal to the crankshaft axis when the test engine is not in operation.
