  • Patent number: 10288024
    Abstract: A fuel pump includes a housing provided with an axial bore defining a compression chamber. The pump is further provided with a cylindrical piston slidably arranged in the bore, the piston extending from a top extremity that is inside the bore, defining a high pressure extremity, to a lower extremity, defining a low pressure extremity. The piston is able to reciprocally slide between a lower position where fuel at low pressure enters the compression chamber via an inlet and, a top position where fuel present in the compression chamber is pressurized before being expelled via an outlet. The piston is also provided with a recess surrounded by a peripheral wall arranged on its high pressure extremity, the recess and peripheral wall enabling the piston to expand radially when fuel in the compression chamber is pressurized.

  • Patent number: 10273901
    Abstract: Methods and systems are provided for a cam carrier insert coupled to a cylinder head of an engine. In one example, a system may comprise: a cylinder head with a cam bearing tower; a cam carrier insert positioned in the cylinder head; and a camshaft, the camshaft directly supported by the cam bearing tower and directly supported by the cam carrier insert. By mounting a first portion of the cam shaft to the cam bearing tower and a second portion of the cam shaft on the cam carrier insert, the system may operate deactivatable and non-deactivatable intake or exhaust valves of one or more engine cylinders in the engine. In this way, packaging of engine components within the cylinder head may be improved while promoting better engine performance.

  • Patent number: 10273920
    Abstract: In a tappet-driven single piston pump, piston side loads caused by return spring out-of-squareness are eliminated by effectively piloting the piston return spring, preferably the associated spring seat, by the tappet, thereby allowing the tappet to bear the spring side load. The piston engages and is returned by the spring seat, but radial clearance between the piston and spring seat is greater than radial clearance between the spring seat and tappet, thus eliminating side loading imparted to the piston. The spring seat can be considered a piston retainer, in which the piston is not closely attached to the retainer but instead exhibits a predefined radial clearance greater than the piloting clearance between the retainer and the tappet.

    Abstract: A method for a hybrid-electric vehicle is presented, wherein a fuel tank is sealed closed during a first condition that includes an inductive charging event, and wherein degradation of a fuel tank pressure transducer is indicated responsive to a fuel tank pressure transducer output failing to increase above a threshold following an active testing duration. The outer walls of the fuel tank may include ferrous components which are energized by a magnetic field generated during the inductive charging event, thus heating the fuel tank and the fuel stored within. In this way, the pressure within the sealed fuel tank increases during the inductive charging event, and a determination may be made as to whether the output of the fuel tank pressure transducer is rational.

  • Publication number: 20140366849
    Abstract: A fuel pump assembly comprises a pumping plunger for pressurising fuel within a pumping chamber during a plunger pumping stroke; and a cam follower arrangement for imparting drive to the pumping plunger including a cam follower member which cooperates with the pumping plunger. The cam follower arrangement is biased into engagement with a cam drive whilst a degree of relative movement along the plunger axis is permitted between the cam follower member and the pumping plunger. At least one of the pumping plunger and the cam follower member includes a surface provided with a feature which defines together with a facing surface of the other of the pumping plunger and the cam follower member, a cushioning volume therebetween for receiving fluid to provide a cushioning effect as the pumping plunger and the cam follower member move into contact with one another, in use. The feature includes a flat central portion and an annular region which is conical in form and which is angled relative to the facing surface.

  • Patent number: 8887694
    Abstract: The fuel pump driving structure includes a camshaft and a pump cam member. The camshaft is rotatably supported at an end by a cylinder head. The pump cam member has a fitting hole into which the end of the camshaft is press fitted, and is operatively coupled to a high-pressure fuel pump. The pump cam member includes a pump cam section and a first contact section. The pump cam section has a first lift portion operating the high-pressure fuel pump, and a base circular portion that does not operate the high-pressure fuel pump. The first contact section is in a position offset from a position of the first lift portion with respect to a circumferential direction and contacting a portion of the camshaft in an axial direction at a position radially outward of an external circumferential surface of the one end of the camshaft.
