Method and apparatus for rotating liners in a rotating liner engine

Abstract

A rotating liner driving mechanism for converting existing engines castings to a rotating liner configuration (RLE) with minor changes to the engine or casting. A pulley is connected to the main accessory belt in the front of the engine and drives a shaft parallel to the crankshaft but external to the engine. Via a 90 degree gearbox, the driving rotation is turned about normal to the crankshaft and block deck face. This shaft drives a driving gear through a gear cover, which then drives one of the liners. Gears in the liner flanges propagate the rotation to all liners. An inline engine needs only one set of pulleys and driving mechanisms, but a V-engine may require two, one for each bank of cylinders. The driving pulley can have mechanisms included so that the gear ratio between crankshaft and rotating liners can be varied during engine operation.
