摘要： In an internal combustion engine, a fixed engine valve timing profile may be combined with a variable profile produced by a valve actuator coupled to one or more engine valves. By controlling one or more engine valves independent of the fixed timing profile, engine gas flow may be more flexibly regulated, thereby optimizing engine performance under a wide variety of operating conditions. In one embodiment, enhanced internal exhaust gas recirculation (EGR) may be achieved. A turbocharger may be used, along with the control provided by the valve actuator, to further control engine gas flow. In this manner, the present invention facilitates greater control of engine gas flow with minimal cost and complexity.

摘要： A fuel injector includes a spool control valve, a plunger which moves in a fuel pressure chamber between retracted and full stroke positions. The fuel injector may include a spill port for spilling fuel from the fuel pressure chamber, the spill port being open at the start and closed by the translating motion of the plunger to delay the start of injection. The fuel injector chamber may further include a control port which is closed at the start of plunger motion and is opened by the plunger to connect the pressure chamber to a needle back chamber to bias the needle valve closed. The needle back chamber becomes isolated from the pressure chamber by further movement of the plunger and includes a pressure control passage to allow the pressure therein to decay upon control port closure, thereby effecting split injection or rate shaping.

摘要： While an engine (10, 10A, 10B, 10C, 10D, 10E) is operating, a control system (22) processes data for certain engine operating parameters to calculate a quantity of exhaust gas needed to satisfy an exhaust gas recirculation requirement. If a primary EGR control loop (34) alone can satisfy the calculated quantity of exhaust gas, a secondary EGR control loop (36) is closed while the primary EGR control loop is controlled to satisfy the calculated quantity. When the processing determines that the primary EGR control loop alone cannot satisfy the calculated quantity, the secondary EGR control loop is open concurrently with the primary EGR control loop and both the primary EGR loop and the secondary EGR loop are controlled to cause the combined flow of exhaust gas through the primary EGR control loop and flow of exhaust gas through the secondary EGR control loop to satisfy the calculated quantity.

摘要： A fuel injector including a delay device, the fuel injector having an electric controller for controlling the flow of a high pressure actuating fluid responsive to initiation and cessation of a pulse width command, the pulse width command defining the duration of an injection event, and an intensifier being in fluid communication with the controller, the intensifier being translatable to increase the pressure of a volume of fuel for injection into the combustion chamber of an engine; the delay device includes an apparatus, shiftable between a first disposition and a second disposition over a certain period of time after initiation of the pulse width command, the period of time effecting a delay in initiation of fuel injection after initiation of the pulse width command. In one embodiment, a bias against shifting the apparatus from said first disposition to the second disposition is effected by the actuating fluid to reduce variations in the delay period under variable actuating pressure conditions. A method of stabilizing fuel injection events, includes the steps of sending a pulse width command to a controller to define an injection event, the controller porting an actuating fluid to affect an intensifier responsive to reception of the pulse width command, and interposing a delay in the actuating fluid affecting the intensifier.
