A method of designing and producing a push rod uses continuous or discontinuous or chopped fiber pre-impregnated composite material wrapped around or surrounding a titanium tube, wherein the method allows push rod designers to machine several different push rod designs, lengths, diameters, and end types. The push rod would be shaped in a basic form (a blank having suitable length and stiffness), and then machined into a push rod. After the specific machining is performed, the oil drain hole is substituted with a titanium tube and the ends are capped with a suitable end for bearing against the rocker or the lifter, we then finish machining all surfaces. Push rods are then impregnated with Sodium Silicate to arrest fluid uptake.

A valve for restricting flow through an opening of a control valve in a vehicle engine includes a tubular shell having a central axis that extends between open ends of the shell. The shell also includes a base and a blocking element having an interior surface exposed to an internal space of the shell and an exterior surface exposed to an exterior space surrounding the shell. The blocking element is connected to the base by a deflectable connector such that the blocking element can be deflected towards the central axis in response to fluid pressure acting on the exterior surface, and away from the central axis in response to fluid pressure acting on the interior surface so as to selectively block the opening.

Temperature independent camshaft phaser actuation strategy

Номер: US10612431B2
Автор: Andrew MLINARIC
Принадлежит: Schaeffler Technologies AG and Co KG

A method of operating a cam shaft phaser including a stator including a radially inwardly extending protrusion, a rotor including a radially outwardly extending protrusion and a slot in the radially outwardly extending protrusion, a cover non-rotatably connected to the stator, a chamber circumferentially bounded by the radially inwardly extending protrusion and the radially outwardly extending protrusion, a pin disposed in the slot, and a first channel connecting the chamber with the slot. The method comprises: blocking, with the locking pin, rotation of the rotor with respect to the stator; applying pulse width modulation voltage to a control valve as a non-rectangular wave form; flowing fluid from the control valve to the chamber; flowing the fluid through the first channel to the slot; axially displacing the locking pin with the fluid; disengaging the locking pin from the cover; and rotating the rotor with respect to the stator.

Double-reed exhaust valve engine

Номер: US9068484B2
Автор: Charles L. Bennett
Принадлежит: Lawrence Livermore National Security LLC

An engine based on a reciprocating piston engine that extracts work from pressurized working fluid. The engine includes a double reed outlet valve for controlling the flow of low-pressure working fluid out of the engine. The double reed provides a stronger force resisting closure of the outlet valve than the force tending to open the outlet valve. The double reed valve enables engine operation at relatively higher torque and lower efficiency at low speed, with lower torque, but higher efficiency at high speed.

Electromagnetic valve apparatus with nonlinear spring

Номер: US9395012B2
Автор: Bradley E. Paden, Brian A. PADEN, David B. Paden, Michael R. Ricci, Murat Okcuoglu, Orlo James Fiske
Принадлежит: LAUNCHPOINT TECHNOLOGIES Inc

An electromagnetic valve apparatus with nonlinear springs for variable valve timing in an internal combustion engine. The apparatus includes a valve, floating spring assembly, translational cam, and motor. The cam and spring serve to minimize lash and valve stem bending forces. During opening and closing of the valve, spring potential energy is converted into valve kinetic energy and then back into potential energy at the end of the motion. The potential energy is then available for the next opening/closing event. The motor initiates motion, replaces friction and vibration losses, and terminates motion. However, the motor supplies minimal energy as the valve opens and closes, and vice-versa, naturally due to combined effects of system inertia and the nonlinear spring. In addition to valve control, the apparatus may be applied to fuel injectors, or any reciprocating linear or rotary mechanism where electronic control is used.

In a spark ignition engine, a thermal insulation thin layer is formed over a wall surface, facing an inside of a combustion chamber, of a base material forming the combustion chamber, and for a thermal conductivity λ [W/(m·K)], a thermal diffusivity κ [mm 2 /s], and a thickness L [μm] of the thermal insulation thin layer, L≧16.7×λ and L≦207.4×(κ) 0.5 are satisfied. With such a configuration, a heat loss Q_total escaping from gas in a cylinder to the wall of the combustion chamber over all strokes can be reduced, and the thermal efficiency can be improved without inducing degradation of knocking due to an increase in an amount of heating Q_intake of the gas in the cylinder during an intake stroke.
