发明名称 A LARGE TWO-STROKE INTERNAL COMBUSTION ENGINE
摘要 <p>An internal combustion engine (1) has hydraulically driven exhaust valves (13) and fuel pumps (18). The hydraulic drives are controlled by means of a computer (16) and electrically activated positioning means (64) setting a spool in a spool valve. If the electronic control of the engine fails, the spool movement may be controlled by a first piston (41) on which the pressure in a hydraulic hose or conduit (48) acts, said conduit extending to a second piston (44) which may follow a cam (26) on a rotating camshaft. The hydraulically driven cylinder members (13, 14, 18) associated with each of the engine cylinders are mounted at the pertaining cylinder, whereas the camshaft (23) independently of the positioning of the cylinder members is disposed at an appropriate shaft drive, such as the crankshaft (11). The cam shaft has a very short length and small mass and may for instance be disposed at one end of the engine.</p>
