Abstract: A tappet assembly (100) used in mechanical equipment includes a tappet body (108) having a cylindrical shape and including a lower carrier portion (152) and an upper shell portion (158) having a cavity (150) defined by an inner wall (160) of the upper shell portion (158) and a top surface (154) of the lower carrier portion (152). The lower carrier portion (152) and the upper shell portion (158) are integrally formed as a single-piece unit. A post (162) extends upwardly from the top surface (154) of the lower carrier portion (152) and is configured to reduce a peak contact pressure associated with the tappet body (108).

Abstract: A system, apparatus, and method are disclosed for controlling a fuel injector using multipulse fuel injection. According to at least one aspect of the present disclosure, the system includes a fuel sequence controller configured for use with a fuel injector having an injector configuration modeled by a body pressure characteristic that includes a rail pressure and an injection rate shape, where the fuel sequence controller is structured to determine an estimate of the injected fuel quantity delivered from the fuel injector at the determined body pressure characteristic.

Abstract: The present disclosure provides a high-pressure fuel pump including a barrel unit, a plunger, and a camshaft assembly having an eccentric cam lobe including a surface of the lobe. A follower is provided between the plunger and the surface of the lobe of the camshaft assembly to facilitate translation between the rotational movement of the camshaft assembly to axial movement of the plunger. The follower includes arcuate surfaces configured to mate with corresponding arcuate surfaces of the lobe of the cam shaft assembly and the plunger, respectively.

Abstract: A pump inlet valve includes a valve body and a plunger assembly. The valve body includes a valve body cavity. The plunger assembly is arranged within the valve body cavity and includes a plunger body, a plunger barrel formed at the plunger body so as to form a plunger barrel volume, and a plunger. The plunger is configured to move within the plunger barrel to thereby allow a fluid to flow past the plunger assembly when the plunger is in an open position and to inhibit the fluid from flowing past the plunger assembly when the plunger is in a closed position. The plunger is configured to allow continuous fluid communication between the plunger barrel volume and a supply inlet, through which fluid is supplied to the pump inlet valve.
