摘要： A method and an assembly for controlling the pressure in a high-pressure region of an injection system in an internal combustion engine. A set high pressure is compared to an actual high pressure in order to determine a control deviation, the control deviation representing an input variable of a controller. A high pressure pump is controlled by a solenoid valve and the angle at which the delivery of fuel by the at least one high-pressure pump is to start is used as a manipulated variable of the high-pressure closed-loop control system.

摘要： The invention relates to a method for testing an electrically activated actuator in a fuel delivery device (10) of an internal combustion engine, wherein the electrical actuator is a controllable valve (15) that is arranged on the inlet side of a high-pressure pump (16). The high-pressure pump (16) conveys fuel into a fuel store (17) having a pressure controller (20). The fuel store (17) is connected to at least one injector (23). The method comprises the following steps: 1) increasing the rotational speed of the high-pressure pump (16), 2) activating the controllable valve (15) until the pressure in the fuel store (17) has reached a first low pressure level, 3) changing the supply of current to the controllable valve (15) by a first specified value such that the controllable valve (15) is opened further and simultaneously maximizing an injection amount by means of the at least one injector (23) until the pressure in the fuel store (17) has reached a first threshold value, 4) activating the controllable valve (15) until the pressure in the fuel store (17) has reached the first low pressure level again, 5) determining a further quantity, which depends on the low pressure level and a maximum value of the pressure that was reached in the fuel store (17).

摘要： A method for operating a fuel injection system with pressure reduction, and a fuel injection system that includes a fuel injection valve with a servo valve are provided. The method for operating a fuel injection system includes performing a desired pressure reduction in the pressure accumulator using at least one fuel injection valve of the fuel injection system. This is achieved by opening a servo valve in the fuel injection valve, which is opened, during a pressure reduction phase, just wide enough that the actual closing element remains closed and as a result no fuel injection process takes place.

摘要： Methods and systems are provided for fuel systems including a gaseous fuel. Fuel rail over-pressure may be addressed by temporarily closing a fuel tank valve of the gaseous fuel and initiating diagnostics routines to determine if a pressure regulator is degraded. If the pressure regulator is degraded, one or more fuel system components may be adjusted to enable fuel rail pressure control.
