    Abstract: A component includes a transmission arrangement for transmitting a force between an actuator (102) and a control valve (172). The transmission arrangement includes a post (116) that is associated with the actuator (102). The control valve (172) is displaceable to an open position from a closed position when an opening (124) force is applied to the control valve (172) that is greater than a closing force provided to the control valve (172). The transmission arrangement is disposed in the component between the post (1 16) and the control valve (172) actuator (102) and arranged to mechanically transmit by physical contact an actuator (102) force from the post (116) to the control valve (172) when the post (116) begins to travel towards the extended stroke position, and hydraulically amplify the actuator (102) stroke between the post (116) and the control valve (172) when the post (116) travels from the retracted stroke position to the extended stroke position.

    Abstract: In one aspect, the present disclosure is directed to a tappet assembly for a machine. The assembly may include a tappet body, a pin fixedly mounted in the tappet body, and a substantially cylindrical roller mounted about the pin. The roller may have a substantially cylindrical outer surface with a circumferential dimension and a width dimension, the width dimension being defined by two lateral edges. The roller may be configured to provide rolling contact between the outer surface of the roller and a cam lobe. The outer surface of the roller may be crowned such that at maximum operational loading conditions of the machine a footprint of contact pressure from the cam lobe is spread substantially the full width of outer cylindrical surface of the roller.

    Abstract: A method of operating a fuel system (10) for a compression ignition engine includes supplying bio fuel, which may be part of a mixture, to an inlet (31) of a fuel lubricated pump (16). At least one bearing (47) of the pump (16) is lubricated with the bio fuel. The fuel lubricated pump (16) supplies high pressure fuel to a common rail (14). A plurality of fuel injectors (12) are fluidly connected to the common rail (14), and each include at least one nozzle orifice (39) for injecting the biofuel into the combustion space of the engine. Nozzle orifice coking is limited at least in part by employing a spinodal bronze alloy in the bearing (47) of the fuel lubricated pump (16).

    Abstract: A method (100) is provided for predicting the likelihood of cavitation damage occurring on a surface (14a) of a hydrodynamic component (10). The method may include creating (102) a computational fluid dynamics (CFD) simulation of the hydrodynamic component, wherein creating the CFD simulation includes simulating a fluid proximal to the surface of the hydrodynamic component. The method may also include selecting (103) a location on the surface of the hydrodynamic component, wherein the selected. location is exposed to the simulated fluid. The method may further include determining (104) the mean pressure and standard deviation, the standard deviation of the rate of change in pressure, the mean void percentage and standard deviation, and the standard deviation of the rate of change in void percentage for the fluid at the selected surface location. The method may also include analyzing (105) at least one of the mean pressure and standard deviation, the standard deviation of the rate of change in pressure, the mean void percentage and standard deviation, and the standard deviation of the rate of change in void percentage for the fluid at the selected surface location to predict the likelihood of cavitation damage occurring at the selected surface location.
