摘要： A fuel injection equipment for an internal combustion engine is piloted by a central electronic unit, the equipment includes a piloted low pressure pump drawing the fuel from a low pressure tank and sending the fuel toward a piloted inlet valve controlling the inlet of a high pressure pump which pressurizes the fuel and sends it pressurized toward a manifold to which is connected at least one injector. The equipment also includes a high pressure accumulator, distinct from the manifold, and a piloted high pressure valve in fluid communication between the outlet of the high pressure pump and the manifold so that the high pressure accumulator stores and delivers pressurized fuel to the manifold.

摘要： A camshaft phaser includes an input member; an output member defining an advance chamber and a retard chamber with the input member; a supply passage; a vent passage; and a valve spool within the output member which is moveable between a first and second position. The first position prevents communication between the advance chamber and the vent passage, prevents communication between the retard chamber and the vent passage, and allows oil to flow from one of the advance chamber and the retard chamber to the other of the advance chamber and the retard chamber. The second position provides communication between the vent passage and one of the advance chamber and the retard chamber, prevents communication between the vent passage and the other of the advance chamber and the retard chamber, and provides communication between the supply passage and the other of the advance chamber and the retard chamber.

摘要： An ignition coil includes a magnetically-permeable core; a primary winding disposed outward of the core; a secondary winding disposed outward of the primary winding, inductively coupled to the primary winding, and terminating at one end thereof in a low-voltage end and terminates at another end thereof in a high-voltage which is electrically connected directly to a terminal through an electrically conductive polymer; and a case defining an interior having an interior surface such that the core, the primary winding, and the secondary winding are received within the interior of the case such that the at least one of the low-voltage end and the high-voltage end, the terminal, and the electrically conductive polymer are disposed within the recess and such that the electrically conductive polymer is in direct contact with the interior surface within the recess.

摘要： A camshaft phaser includes an input member and an output member defining an advance chamber and a retard chamber; a valve spool moveable along an axis between an advance position and a retard position and having a valve spool bore with a phasing volume and a venting volume defined therein such that the phasing volume is fluidly segregated from the venting volume, the valve spool having a first spool supply passage and a second spool supply passage which is diametrically opposed to the first spool recirculation passage. The first spool supply passage and the second spool supply passage each provide a path for pressurized oil to be supplied to the phasing volume from an oil source.

摘要： A sensor system includes a common gas chamber and a reference gas chamber that respectively receive an exhaust gas and a reference gas. A Nernst cell is exposed to the common gas chamber and the reference air chamber and provides a reference signal indicative of an oxygen difference between the common gas chamber and the reference gas chamber. An oxygen electrochemical pump cell is exposed to the common gas chamber to provide an oxygen signal indicative of an oxygen-only concentration. A gas electrochemical cell is exposed to the common gas chamber and the reference gas chamber and provides a gas signal indicative of a gas concentration. A processor includes a pulsation module that provides a positive and a negative excitation voltage to the gas electrochemical cell for a duration and that are each followed by a decay curve indicative of the gas concentration.

摘要： A sensor system includes a common gas chamber and a reference gas chamber respectively configured to receive an exhaust gas and a reference gas. A Nernst cell is exposed to the common gas chamber and the reference air chamber. The Nernst cell provides a reference signal indicative of an oxygen difference between the common gas chamber and the reference air chamber. An oxygen electrochemical pump cell is exposed to the common gas chamber and exhaust gas and provides an oxygen signal indicative of an oxygen only concentration. A NOx electrochemical cell is exposed to the common gas chamber and provides a NOx signal indicative of a NOx concentration. A processor is in communication with the Nernst cell, the oxygen-only electrochemical pump cell and NOx electrochemical cells. The processor outputs oxygen and NOx signals and provide a NOx concentration and oxygen concentration of the exhaust.

摘要： A fuel pump housing includes a pumping chamber that is substantially spherical and a drilling intersecting the pumping chamber at an opening. The drilling transitions into the pumping chamber at a transition region of progressively increasing diameter. The transition region and the spherical pumping chamber are configured such that a peak stress in the fuel pump housing is at a location that is spaced away from the opening.

摘要： A valve assembly includes a housing with a bore, a supply port in fluid communication with the bore, a control port in fluid communication with the bore, and a vent port in fluid communication with bore such that the vent port is located at a location of the housing that is between the supply port and the control port. A valve seat assembly with a valve seat body is disposed within the housing and defines a control chamber in constant fluid communication with the control port, a vent path from the control port to the vent port, and a supply passage which provides constant fluid communication from the supply port to the control chamber. A vent valve member is selectively seated and unseated with the vent valve seat to selectively prevent and permit fluid communication from the control port to the vent port respectively.

The first spool recirculation passage and the second spool recirculation passage provide paths for oil to flow from the advance chamber or the retard chamber to the phasing volume depending on the position of the valve spool.
