Title:
【発明の名称】2サイクル圧縮解放制動を備えた4サイクルエンジン
Document Type and Number:
Japanese Patent JP2001505272
Kind Code:
A
Abstract:
An internal combustion engine has engine cylinder intake and exhaust valves that are operated by intake and exhaust cams via hydraulic linkages. The hydraulic linkages have selective lost motions that allow selective modification of the openings and closings of the engine cylinder valves. These modifications may also include complete omission of all response to particular lobes on the cams. The hydraulic linkages may be interconnected so that some intake valve openings are produced by an exhaust cam lobe and/or some exhaust valve openings are produced by an intake cam lobe. The linkages and linkage interconnections are preferably controlled electronically. The engine is preferably operable in either four-cycle positive power mode or two-cycle compression release engine braking mode. The intake cam may have plural lobes or only one lobe, while the exhaust cam may only have one lobe.
