Abstract: A system and a method for executing tasks for an internal combustion engine (14) has two control devices (1, 2), with the two control devices (1, 2) being provided in order to process the tasks independently of one another, with the first control device (1) having a first release signal and a first switchover signal, with the second control device having a second release signal and a second switchover signal, with, by exchanging the two release signals and the two switchover signals, it being defined that only one of the two control devices (1, 2) executes a defined task at the same time.

Abstract: An electric generator including: a prime mover; an alternator; a first drive shaft connected to the prime mover; a second drive shaft connected to the alternator; and an overdrive assembly including: a speed conversion assembly connected to the first drive shaft; and a centrifugal clutch connected to the speed conversion assembly and to the second drive shaft. An electric generator, including: a prime mover; an alternator; and an overdrive assembly. For a load on the generator at or above a load threshold, the overdrive assembly is arranged to form a first torque path from the prime mover to the alternator, the first torque path bypassing the overdrive assembly. For a load on the generator below the load threshold, the overdrive assembly is arranged to form a second torque path from the prime mover to the alternator through the overdrive assembly.

Abstract: The invention discloses a method for estimating an injected quantity of fuel of an isolated injection. The segment time of the cylinder in which the isolated injection takes place is evaluated numerically by forming the second temporal derivation. With the aid of the second temporal derivation of the segment time the injection parameters are updated using test quantity—test torque performance data.

Abstract: A device for clamping a crankshaft in a grinding machine has a rotary face plate which defines a lubricant-filled space and carries two parallel shafts for removable clamping jaws. The jaws can cooperate with a support, which is removably affixed to the face plate, to hold a crankshaft therebetween. The mechanism for pivoting the jaws toward and away from the support has a feed screw which is accessible from the outside of the face plate and extends into the space where it meshes with a nut which can pivot two bell crank levers in opposite directions. The bell crank levers are mounted on the two shafts, and those arms of the levers which must be pivoted by the nut in order to move the respective jaws toward the support carry pistons which deform packages of dished springs when the jaws bear against the crankshaft.

Abstract: A machine tool for maching of crankpins on crankshafts, or of similarly ts-axially offset portions of other types of workpieces, includes an arrangement for indexing the workpiece to a plurality of different positions to place new crankpins in position for machining without having to unclamp the workpiece or stop its rotation. Indexing accuracy is greatly improved and all indexing-related operations are powered by the prime mover of the machine tool rather than requiring separate drives.
