Abstract: An ignition system for an internal combustion engine includes a prechamber ignition device, a fuel admission valve for the prechamber ignition device, and a combustion consistency control mechanism configured to receive data indicative of at least one of a magnitude of a peak pressure in a combustion prechamber of the prechamber ignition device or a timing of the peak pressure in the combustion prechamber. The combustion consistency control mechanism calculates an error based on the data, and outputs a valve opening command to a fuel valve to produce a shot of combustion-initiating gases from the prechamber device, the valve opening command being based on the error.

Abstract: A method for monitoring quality of a hydraulic fluid in an electro-hydraulic (EH) valve is disclosed. The method includes applying predetermined signal to a solenoid coil, surrounding a pusher pin in EH valve, to facilitate oscillation of a pusher pin in EH valve to change static friction between the pusher pin and a cavity of EH valve, to dynamic friction. EH valve includes a housing defining the cavity having an end wall. Cavity slidably receiving the pusher pin having a first end and a second end. The hydraulic fluid is received between the first end of the pusher pin and the end wall. The oscillation of the pusher pin generates an acoustic wave that propagates through the hydraulic fluid. The method further includes determining the quality of the hydraulic fluid based on one or more characteristics of the acoustic wave detected by an acoustic sensor positioned on the end wall.

Abstract: A hauling machine is disclosed. The hauling machine may include a dump body and an inertial measurement unit (IMU) disposed proximate to the dump body. The IMU may be configured to measure an impact of a payload material on the dump body during a first load cycle, and generate impact data based on the impact of the payload material. The hauling machine may also include a controller in operative communication with the IMU. The controller may be configured to: receive the impact data from the IMU, estimate a center of gravity, a net load, and an amplitude of the impact of the payload material based on the impact data, and determine a desired dumping point of the payload material into the dump body for a second load cycle based on the center of gravity, the net load, and the amplitude of the impact.

Abstract: An engine pressure sensor monitoring system uses the position of a wastegate in a turbo-charged engine when known and calibrated engine operating conditions occur to provide diagnostic information for various engine pressure sensors and for the operation of the wastegate itself. Discrete measurement windows are defined for engine conditions with specific values for parameters that may include rpm, torque, injection timing and fuel consumption. Other sensor readings for intake manifold pressure, turbocharger compressor output pressure, peak cylinder pressure, and wastegate valve position during these measurement windows should match predicted values. If measured and predicted values do not match, one or more sensors may be bad and an alarm may be raised.

Abstract: A system for supplying fuel to an engine is disclosed. The system includes a first sensing unit for determining multiple operating parameters and multiple ambient conditions of the engine. The system includes an adaptive adjustment mechanism, a pressure regulator having a first valve and a second valve, and a controller communicating with the adaptive adjustment mechanism and the pressure regulator. The controller determines a first error and a second error associated with a pressure of a fuel supply to a pre-combustion chamber and a main combustion chamber, respectively, and receives an output signal indicative of an adjustment factor determined by the adaptive adjustment mechanism. The controller controls the first valve and the second valve based on the first error, the second error, and the output signal, to supply the fuel to the pre-combustion chamber and the main combustion chamber at a first pressure and a second pressure, respectively.
