摘要： A fuel injector nozzle assembly includes an injector body including a valve seat with a supply passage through which fuel flows generally along a supply axis. The valve seat presents an upper surface which is adapted to engage a valve to seal the supply passage. A nozzle plate is mounted onto the valve seat and includes a plurality of orifice holes therein through which fuel flows. The valve seat further includes a first edge protrusion protruding into the fuel flow for generating a first separation of the fuel flow, thereby creating a plurality of small eddies which are entrained within the fuel flowing adjacent thereto. A turbulence cavity is defined by the nozzle plate and the valve seat wherein fuel flows into the turbulence cavity through the supply passage and out from the turbulence cavity through the plurality of orifice holes.

摘要： A stratified exhaust gas re-circulation (EGR) engine uses an exhaust port per cylinder for exhausting exhaust gases and to re-circulate exhaust gas. The EGR valve may be phased from the exhaust stroke to the intake stroke. The EGR valves that control the exhaust gas re-circulation ports may be on a separate camshaft from the other valves. The EGR ports and an intake port for each of the cylinders may be helical or tangential ports that stratified the exhaust gas and the air in the cylinder. The engine may be a direct injection or a port fuel injection engine with one or more exhaust manifolds. The exhaust gas re-circulation ports may be controlled by a single flow valve or each port may have a separate flow valve. The intake ports may be controlled by a single flow valve or each intake port may have a separate flow valve.

摘要： A four-stroke reciprocating internal combustion engine that uses stratified exhaust gas recirculation to improve combustion is disclosed. The engine includes at least one combustion chamber defined by a cylinder, a reciprocating piston contained within the cylinder, and a cylinder head. Each combustion chamber is in fluid communication with at least one intake port and at least one exhaust port. At least one intake port includes an associated intake valve, an intake flow motion generating device and an associated intake flow direction control device for creating an intake fluid flow near the center of the cylinder. At least one exhaust port includes an exhaust valve that opens during the intake stroke at part load, an exhaust flow motion generating device and an associated exhaust flow direction control device for creating an exhaust fluid flow near the outer periphery of the combustion chamber during the intake stroke at part load. An engine controller processes signals from at least one sensor and outputs a control signal to a variable valve lift and timing system for operating each intake valve and each exhaust valve such that an exhaust residual flow is inducted through at least one exhaust port into the combustion chamber and air or an air/fuel mixture is simultaneously inducted through at least one intake port into the combustion chamber. If air is inducted into chamber, fuel is directed into the air in the chamber. The engine produces a stratified exhaust gas and air-fuel mixture that includes recirculated exhaust gas which rotates about the cylinder axis and remains substantially along an interior wall of the cylinder and a stoichiometric air-fuel mixture which rotates about the cylinder axis and occupies a portion of the piston surface and the remaining portion of the combustion chamber. Because of the stoichiometric operation of the engine, conventional three-way catalysts can be used for emission control.

摘要： A direct injection fuel injector and method of operation wherein high fuel pressure exerting an opening force on an injection valve is slightly overbalanced by a return spring tending to close the valve. A first solenoid acts to open the valve against the excess return spring force and a second solenoid acts to close the valve when the first solenoid is de-energized. Rapid valve closing is provided by energizing the second solenoid before de-energizing the first solenoid, the force of the second solenoid when the valve is open being insufficient to overcome the force of the first solenoid holding the valve open. Thus, the second solenoid magnetic force is fully developed and quickly closes the injection valve when the first solenoid is de-energized. Various additional features are disclosed.

摘要： A direct injection fuel injector spray nozzle assembly and method of operation wherein the nozzle assembly comprises a three hole swirler with a central valve guide, a convergent swirl chamber, a conical nozzle valve and a conical valve seat. High pressure fuel at, for example, 10 MPa is delivered to the injector and passes through internal passages with a negligible pressure drop until reaching the nozzle assembly. The size, configuration and orientation of the swirl chamber and swirler holes are selected to achieve a desired swirl intensity at the nozzle exit. At least 30 percent and preferably about half of the fuel pressure, 5 MPa, is consumed in passing through the swirler holes and developing the swirl motion. The remaining pressure drop of at least 30 percent, preferably half, 5 MPa, occurs at the sealing point of the valve head against the valve seat. The outwardly opening conical injection valve and seat, together with the high pressure, combine to provide essentially separate control of the elements of fuel droplet size, spray penetration and spray angle. Swirl intensity adjusted by varying the swirler hole locations can serve as a primary control factor for spray penetration. The cone angles of the valve and seat act as a primary control for spray angle. Droplet size is directly affected by the valve opening which determines the liquid sheet thickness of fuel passing through the spray nozzle, as well as by the fuel pressure drop through the nozzle.

摘要： The translation lookaside buffer (TLB) of a processor is kept in synchronization with a guest page table by use of an indicator referred to as a “T” bit. The T bit of the NPT/EPT entries mapping the guest page table are set when a page walk is performed on the NPT/EPT. When modifications are made to pages mapped by NPT/EPT entries with their T bit set, changes to the TLB are made so that the TLB remains in synchronization with the guest page table. Accordingly, record/replay of virtual machines of virtualized computer systems may be performed reliably with no non-determinism introduced by stale TLBs that fall out of synchronization with the guest page table.

摘要： The present disclosure provides an electronic device having a USB interface and a method for starting USB communication with such an electronic device, so as to solve the problem of a risk of damaging a mobile phone terminal device arising from sharing of an interface by a charger and a USB communication cable in the related art. In the electronic device, a port GPIO of a baseband chip is connected to a pin USB_VBUS of a USB interface of the baseband chip; based on this circuit, a power management chip detects a state of plugging-in-or-pulling-out of the charger and generates a corresponding interrupt request; and the baseband chip controls the GPIO to output a corresponding level according to the interrupt request. By connecting the port GPIO and the pin USB_VBUS and controlling an output level of GPIO with a software, a high level or a low level (as a triggering signal for starting or terminating the USB communication) is input to the pin USB_VBUS, thus avoiding damage to the device.
