摘要： A method of operating an actuator for electromagnetically controlling a valve in an internal combustion engine involves supplying a heating current to the operating coils of the actuator before starting the internal combustion engine from a cold start condition. Thereby, the operating coils, the components surrounding them, and the lubricant are heated to ensure proper viscosity of the lubricant and thus proper operation of the actuator.

摘要： On a known electromagnetic actuator for valve control of an internal combustion engine an armature (1) is moved by magnetic force between the pole faces (21, 31) of an opening magnet (2) and a closing magnet (3) to activate an intake/exhaust valve (5). Owing to the work that has to be done when the intake/exhaust valve (5) is opened in order to counteract the high internal gas pressure in the combustion chamber the opening operation takes longer than the closing operation. The disclosed actuator permits faster opening of the intake/exhaust valve (5), in that the magnetic force exerted by the opening magnet (2) is increased for large stroke lengths (d.sub.o) in comparison with the magnetic force exerted by the closing magnet (3) on the armature (1) in conjunction with the same stroke length (d.sub.s) by the provision of a two-section connecting sleeve (7) enclosing the space between the pole faces (21, 31). This connecting sleeve (7) consists of a ferromagnetic sleeve section (70) attached to the opening magnet (2) and a nonferromagnetic sleeve section (71) attached to the closing magnet (3).

摘要： The invention provides a device for determining the engine load for an internal combustion engine, such device having an input channel for receiving an item of engine speed information, as well as an intake manifold pressure sensor and an air mass flow rate sensor arranged upstream of a throttle valve, and/or a throttle valve angle sensor. The engine speed is fed to a Kalman filter as an input value and at least one of the three variables intake manifold pressure, throttle-valve air mass flow rate and throttle valve angle is fed as a variable measured by the respective sensor. The Kalman filter derives estimated values for the variables intake manifold pressure and throttle-valve air mass flow rate, with which the air mass flowing into a respective cylinder of the engine per working cycle is determined.
