Abstract: Disclosed herein are devices, systems, and methods relating to high-pressure fuel pump designs and features. A high-pressure fuel pump assembly includes a body, a camshaft, and an embossment. The body has a forward end and a rearward end opposite thereof and configured to couple to a low-pressure fuel pump. The camshaft is received and secured within a central bore of the body so as to be rotationally movable within the central bore. A coupler end of the camshaft is configured to couple to a drive shaft of the low-pressure fuel pump. The embossment includes at least one fastener boss configured to receive a fastener to couple the low-pressure fuel pump to the high-pressure fuel pump assembly. The embossment is formed at the rearward end of the body such that thermal stresses that cause geometrical deformations at the embossment are reduced through a range of engine temperature operating conditions.

Abstract: Cold sintering of materials includes using a process of combining at least one inorganic compound, e.g., ceramic, in particle form with a solvent that can partially solubilize the inorganic compound to form a mixture; and applying pressure and a low temperature to the mixture to evaporate the solvent and densify the at least one inorganic compound to form sintered materials.

Abstract: The disclosure relates to fuel pump housings and fuel pump systems incorporating the same. The fuel pump housing includes at least one tappet housing portion configured to receive at least one tappet assembly and a main bore portion fluidly coupled with the at least one tappet housing portion such that the main bore receives a camshaft. The main bore includes an uncut portion and at least one relief cut portion proximal to the at least one tappet housing portion. The uncut portion defines a first centerline, and the relief cut portion defines a second centerline offset from the first centerline.

Abstract: Ionically conducting, redox active additive composite electrolytes are disclosed. The electrolytes include an ionically conductive component and a redox active additive. The ionically conductive component may be an ionically conductive material such as an ionically conductive polymer, ionically conducting glass-ceramic, ionically conductive ceramic, and mixtures thereof.
