METHOD AND MECHANISM TO CONFIRM ENGINE TIMING

摘要

A mechanism and method of confirming engine timing in an internal combustion engine includes two embodiments, which delay the rotation of the camshaft until confirmation that the engine is properly timed based upon the sensors provided by the electronic control systems of the motor vehicle. In one embodiment, a cam gear assembly (100) is joined to a camshaft (40) to enable proper confirmation that the engine is properly timed before enabling the rotation of the camshaft (40). In a second embodiment, a gear assembly (200) is used in conjunction with a crankshaft (38). The crank gear assembly (200) includes an outer ring (32) and an inner ring (34). A brake (36) is provided in the inner ring (34) to prevent movement until sensors in the vehicle have confirmed proper timing of the engine.
