Abstract

An integrated hydraulic system for controlling an engine valve control system wherein each of the reciprocating intake and/or exhaust valves is hydraulically controlled and selectively connected to a source of high pressure fluid and a source of low pressure fluid, and a hydraulically assisted turbocharger selectively connected to a high pressure source of fluid by a solenoid valve, with the turbocharger including a nozzle jet and an impulse type turbine.
