Abstract: An asymmetrical orifice for bypass control in a clean fuel module may include a body having first and second end surfaces and an inner surface defining a bore through the body extending from a first opening through the first end surface to a second opening through the second end surface. The first opening has a first opening inner diameter and the second opening has a second opening inner diameter that is less than the first opening inner diameter. The asymmetrical orifice also includes a flow control contour in the second end surface surrounding the second opening of the bore. The configuration may give the asymmetrical orifice a first discharge coefficient for fluid flowing from the first opening to the second opening that is greater than a second discharge coefficient for fluid flowing in a second direction from the second opening to the first opening

Abstract: A fuel system for a machine is disclosed. The fuel system may include a fuel pump, a pump motor configured to drive the fuel pump, and a pump controller. The pump controller may be operatively connected to the pump motor, a main battery bank of the machine via a power wire and a ground wire, and an engine controller of the machine via a communication wire. The pump controller may be configured to detect a failure of at least one of the communication wire, the power wire, and the ground wire. The pump controller may also be configured to adjust a power output and an operation of the pump motor based on the detected failure of at least one of the communication wire, the power wire, and the ground wire.

Abstract: Operating a machine system includes triggering, based on activation of an on-board electronic control system, interrogation of electronically controlled components installed in a machine to read a plurality of electronic trim files each resident on a different one of the electronically controlled components. A data structure on an electronic storage medium in the control system is populated with the electronic trim files each time the control system is activated, such as by turning on an ignition switch. Operating the machine system also includes outputting control signals based on the electronic trim files to run the machine system based on operation of the electronically controlled components responsive to the outputted control signals.

Abstract: A fuel system is disclosed for use with an engine, including a fuel injector assembly fluidly coupled with a low-pressure fuel conduit, an accumulator, and a cap within an opening in the accumulator. The fuel injector assembly may be structured to draw in low-pressure fuel, pressurize the fuel, and store the pressurized fuel in the accumulator for injection to a combustion chamber. The cap has a pressure sensor and a pressure relief valve therein, and drains fuel leaked past fluid seals between the cap and each of the pressure sensor, the pressure relief valve, and the accumulator by way of a common drain line.
