摘要： A method for controlling a fuel metering system of an internal combustion engine. A activation duration of at least one electrically operated injector determines the injected fuel quantity. The minimum activation duration during which fuel is only just injected being determined in certain operating states. The activation duration being increased/reduced starting at an initial value, and the activation duration during which a signal undergoes a change being stored as the minimum activation duration, in which the difference between the activation duration during which a signal undergoes a change and the stored minimum activation duration is determined, from which correction values for the fuel quantity map of the injector are determined and stored using at least one transfer function, which characterizes the relationship between the minimum injection and activation durations at several test points of the injector and/or the relationship between the activation durations at different test points of the injector.

摘要： At least some embodiments of present disclosure direct to a fuel injection timing drift detection and/or compensation system. In some cases, the system collects or receives a series of fuel pressure data measured by one or more fuel pressure sensors. The system is configured to receive an indication of fuel flow cutout and a start-of-injection command signal. The system calculates a set of pressure drops using the series of fuel pressure data and identifies a selected pressure drop greater than a predetermined threshold to determine a measured start-of-injection timing based on the selected pressure drop. The system is further configured to evaluate whether a fuel injection drifting occurs based on received start-of-injection command signal and the measured start-of-injection timing. In some cases, the fuel injection drifting is used to either compensate fuel injection timing or raise a flag indicating the drifting.

摘要： A method for operating an injection valve by ascertaining an opening time and/or closing time of the injection valve on the basis of a sensor signal. The method includes: providing an analysis point time series by sampling a sensor signal of a sensor of the injection valve; using a nonlinear, data-based first submodel in order to obtain a first model output on the basis of the analysis point time series; using a linear, data-based second submodel in order to obtain a second model output on the basis of the analysis point time series; ascertaining the opening time and/or closing time as a function of the first and second model outputs.

摘要： A fuel system is disclosed. The fuel system may include at least one fuel injector, the at least one fuel injector having an injector body and one or more piezoelectric sensors located in the injector body. The fuel system may include a controller configured to: obtain, from the one or more piezoelectric sensors, one or more pressure measurements associated with a fuel injection process; determine a timing of the fuel injection process based on the one or more pressure measurements; determine an adjustment to the timing based on a comparison of the timing to a reference timing; and adjust the timing of the fuel injection process based on the determined adjustment.

摘要： A control system of a compression-ignition engine is provided, which includes an engine configured to cause combustion of a mixture gas inside the combustion chamber, an injector attached to the engine and configured to inject fuel into the combustion chamber, a spark plug disposed to be oriented into the combustion chamber and configured to ignite the mixture gas inside the combustion chamber, and a controller connected to the injector and the spark plug and configured to operate the engine by outputting a control signal to the injector and the spark plug, respectively. After the spark plug ignites the mixture gas to start combustion, unburned mixture gas combusts by self-ignition. The controller outputs the control signal to the injector so that a fuel injection timing is advanced when the engine operates at a high speed than at a low speed.

摘要： An injection control device controls a fuel injection valve driven by an electric power. The injection control device includes a current detection unit to detect a driving current supplied to a solenoid of the fuel injection valve, an identification unit to identify a theoretical model of the driving current in a state where a movable core moved by an electromagnetic force generated by the solenoid is at rest, and a state detection unit to detect a state of the movable core. The state detection unit detects the state of the movable core, based on a deviation between the driving current detected by the current detection unit and the theoretical model.

摘要： An engine control device controls a cylinder direct fuel injection type spark ignition engine provided with a fuel injection valve configured to directly inject fuel into a cylinder and an ignition plug configured to perform spark ignition for a gas mixture inside the cylinder. The engine control device executes a catalyst warm-up operation for retarding an ignition timing, during a compression stroke of the fuel injection timing, in a case where it is necessary to warm up an exhaust gas purifying catalyst inserted into an exhaust passage. In addition, the engine control device increases a valve overlap period as a piston crown surface temperature increases during execution of the catalyst warm-up operation.
