摘要： A fuel system includes a low pressure fuel system, a high-pressure fuel pump, a common rail, at least one fuel injector, and an engine management system. The engine management system may initiate a recirculating cooling fuel flow through the high-pressure fuel pump for avoiding fuel boiling by either increasing the target pressure of the fuel within the common rail above a threshold level, which triggers opening a high-pressure fuel relief valve, such that fuel supplied by the high-pressure fuel pump is returned to the low pressure fuel system via the high-pressure fuel relief valve, or providing increased internal fuel leakage within the at least one fuel injector, such that fuel supplied by the high-pressure fuel pump is returned to the low pressure fuel system by a return line.

摘要： A flow control system for a fuel injector for an internal combustion engine is provided and includes an inlet port, an outlet, a return port, a 2-way control valve including a control valve member, a shuttle valve and a main valve. The control valve includes a first seat, a first resilient arrangement configured to force the control valve member towards the seat so as to close the control valve, and a first abutment that limits the lift of the control valve member away from the first seat. The first seat of the control valve is slidably arranged in the shuttle control chamber. An end stop for the first seat is provided such that the pressure in a shuttle control chamber tends to move the first seat towards the end stop. The first seat, upon its mechanical contact with a valve member is able to transmit at least a part of the force of the resilient means onto a shuttle valve body in the opening direction of the shuttle valve.

摘要： 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 is provided. The valve mechanism includes a rotatable camshaft including rising and falling ramps designed to interact with a valve control plunger inside a cylinder for actuation of the inlet or exhaust valve under the action of a valve spring. The cylinder communicates with a hydraulic fluid feed line via a check valve and with a hydraulic control circuit allowing a return movement of a valve to be delayed in relation to the timing of the corresponding falling ramp. The hydraulic control circuit includes a first and a second hydraulic fluid flow restrictor connected to the control plunger cylinder at different levels along its longitudinal axis. A selector valve enables a connection between the cylinder and hydraulic fluid return line to be opened via either one only or both flow restrictors.
