摘要： An engine valve actuation system is provided. The engine valve actuation system includes an intake valve that is moveable between a first position to prevent a flow of fluid and a second position to allow a flow of fluid. A cam assembly is configured to move the intake valve between the first position and the second position. A fluid actuator is configured to selectively prevent the intake valve from moving to the first position. A source of fluid is in fluid communication with the fluid actuator. A directional control valve is configured to control a flow of fluid between the source of fluid and the fluid actuator. A check valve is disposed between the directional control valve and the source of fluid, only allowing fluid flow from the fluid source to the directional control valve. A bleed orifice may be disposed between the directional control valve and the source of fluid, in parallel with the check valve.

摘要： A method of controlling a hydraulic system is preferably applied to common rail fuel injection systems. The problem in these systems is to control pressure in the common rail while at the same time maintaining the fluid supply to the rail in a way that precisely meets the dynamically changing consumption demands on the hydraulic system. In order to control the hydraulic system, the present invention contemplates the combination of a standard feedback controller with observer models of the various hardware items that make up the hydraulic system. Using this strategy, the system can generally be thought of as controlling fluid supply in an open loop type fashion based upon the consumption rates estimated by the various observer models, and utilizing a conventional feedback controller to make the slight pump adjustments needed to control pressure and to correct for any errors between the actual hardware performance and that predicted by the observer models.

摘要： A fuel injector for an engine is disclosed. The fuel injector has a plunger disposed within a bore, a nozzle member, a valve needle, a check valve, a spill valve, and a controller. The check valve is movable between a first position at which the valve needle is communicated with the bore, and a second position at which the valve needle is fluidly communicated with a drain. The spill valve is movable between a first position at which fuel flows from the bore to the drain, and a second position at which the fuel from the bore is blocked. The controller moves the spill valve toward its second position and the check valve toward its second position during a downward displacing movement of the plunger. The controller detects an unsuccessful movement of the check valve to the second position, and prematurely halts the current injection event in response to the detection.

摘要： The present invention is an apparatus for controlling the fuel rate to an engine using the throttle position, and for controlling the speed of the engine using decision logic to choose the best alternative among candidate fuel levels. A minimum speed governor determines a minimum fuel level at a predetermined low idle engine speed, a maximum speed governor determines a maximum fuel level at a predetermined high idle engine speed, and at least one fuel rate map is used to determine fuel level based on various engine operating parameters. Each governor outputs a fuel quantity signal based on the difference between the corresponding desired engine speed and the actual engine speed. The fuel rate map may be a multi-dimensional data table that provides fuel quantity signals to optimize engine performance based on the throttle position, engine speed, boost pressure, and other engine operating states. The fuel quantity signals from the lookup tables and the maximum speed governor are compared and the minimum value is chosen. The minimum value is then compared to the fuel quantity signal from the minimum speed governor, and the maximum value between these signals is provided as the output signal from the speed governor portion of the engine's electronic control module.

摘要： The present invention is an apparatus for controlling the amount of fuel delivered to an engine during operation at cold and warm temperatures using different sets of fuel rate maps designed to compensate fuel quantity signals to optimize engine performance. A switching mechanism based on engine coolant temperature is used to select which set of maps to use. When the engine coolant temperature is below a threshold level, a cold torque map provides a signal representing the duration limit of time that fuel is to be injected. A compensating factor derived from a cold temperature smoke map is used to adjust the cold torque map signal to limit the fuel amount to prevent excess smoke. When the engine coolant temperature is above the threshold, a fuel duration limit signal from a standard temperature torque map is compared to a fuel duration limit signal from a standard temperature smoke map, and the minimum between the two signals is selected for output to the fuel injectors.
