TL;DR: The injection pump is particularly suitable for high-pressure injection in Diesel engines, in order to attain an exact electrical control of the supply onset and supply quantity, if a reservoir chamber defined by a deflecting piston is connected to a high pressure chamber that includes the pump work chamber as mentioned in this paper.

TL;DR: In this article, the authors describe a fuel injection apparatus for internal combustion engines with one fuel pump for each cylinder of the engine, which pump has a pump piston, driven by the engine in a reciprocating motion, that defines a pump work chamber to which fuel is delivered from a fuel tank and which communicates with a fuel injector valve that has an injection valve member by which at least one injection opening is controlled and which is movable in an opening direction counter to a closing force by the pressure generated in the pump work chambers.

TL;DR: In this article, a process for controlling and measuring the movement of an armature of an electromagnetic switching member with an excitation coil is proposed, which has the following steps: a current (i) or a voltage (u1) is applied to the excitation winding (3) in order to move the armature into a first actuatable position; before the start of the movement, the current or the voltage is raised above a value at which the armatures remains in the actuated position, and before termination of movement, it is reduced to a defined value, which suff

TL;DR: In this paper, a process for monitoring the mechanical displacement of the armature of an electrovalve actuated by a magnet winding by means of a signal derived from the current flowing through the magnet winding is described.
