摘要： The invention relates to a valve actuation system for providing added motion in the valve mechanism of an internal combustion engine with at least one inlet valve and at least one exhaust valve. The valve mechanism comprises a rotatable camshaft including rising and falling ramps designed to interact with a valve control plunger inside a cylinder (23) for actuation of the inlet or exhaust valve (12) under the action of a valve spring (13). The cylinder (23) communicates with a hydraulic fluid feed line via a check valve and with a hydraulic control circuit (26) allowing a return movement of a valve to be delayed in relation to the timing of the corresponding falling ramp. The hydraulic control circuit (26) comprises a first and a second hydraulic fluid flow restrictor (37, 38) connected to the control plunger cylinder (23) at different levels along its longitudinal axis. A selector valve (31) enables a connection between the cylinder and hydraulic fluid return line (32) to be opened via either one only or both flow restrictors.

摘要： The fuel injection system according to the invention comprises a nozzle (2) with an inlet and a needle (15). A control piston (16) forms a control chamber (17) and abuts the needle such that a higher pressure in the control chamber urges the piston to close the nozzle. A cam-driven plunger (5) forms a plunger chamber (7) connected to the inlet of the nozzle. The system also comprises a common rail (11) for fuel, a feed line (13) and an electrically operated valve (9). The valve isolates the chamber from the common rail and connects it to the line while in a third position, isolates it from both the line and the common rail in a second position, and isolates it from the line and connects it to the common rail in a first position. There are also means (12) for pressurizing the feed line with a relatively low fuel feed pressure and a fuel tank (20). The control chamber is connected to the common rail.
