<p>Disclosed is a control module (10) which controls camless hydraulically driven intake and exhaust valves (20, 22) and a hydraulically driven fuel injector (18) of an internal combustion engine. The module (10) contains a valve assembly to control the intake valve (20), a valve assembly to control the exhaust valve (22) and a valve assembly to control the fuel injector (18). The valve assemblies preferably each contain a pair of solenoid actuated two-way spool valves. The solenoids are actuated by digital pulses provided by an electronic assembly within the module. The solenoid actuated spool valves control the flow of a hydraulic fluid to and from the fuel injector (18) and the intake and exhaust valves (20, 22). The hydraulic fluid opens and closes the intake and exhaust valves (20, 22) as well as the fuel injector (18).</p> |
