Abstract: A arrangement for determining the injection course in an internal combustion engine in which the injection development could not be used heretofore in practice as guide magnitude in the engine control because no stationary measuring sensors are available for the pressure in the injection valve and a through-flow measurement at the feed line to the injection valve is very inaccurate by reason of the occurrence of gas, respectively, vapor bubbles. According to the present invention, the pressure in the injection valve, respectively, the quantity or the flow of the occurring injection medium is derived by a computer from signals of measurement transmitters which determine the stroke of the closure element of the injection valve and the pressure in the feed line to the injection valve or the force with which the closure element of the injection valve abuts in its open end position at an abutment.

Abstract: The invention concerns an external mirror for vehicles, having a mirror casing, in which a mirror glass is held so as to be adjustable, the mirror casing being held stationary, in the operating position, on a mirror base. In the event of a collision, the mirror casing can pivot away, either to the front or to the rear, about two approximately vertical axes located one behind the other in the direction of travel. In the case of a rigid streamlined fairing for both the mirror casing and the mirror base, there are certain problems in pivoting the fairing parts forward so as to avoid contact. To deal with this, the invention proposes a guide part which is rigidly located relative to the mirror casing and which interacts with a guide track in the mirror base. The guide track is so designed that when the mirror casing executes a pivoting motion in the forward direction, the mirror casing first lifts off from the mirror base.

Abstract: A coupling device for rods required to be connected together is proposed, with a connecting element having bores on both sides, into which the ends of the rods can be inserted. One bore ends in an internal ring-shaped groove coaxial to it, in which an angled end of the rod is accommodated. The other bore is constructed as a screw-threaded bore, into which the rod is engageable by a screw-threaded shoulder. In order to insert the angled end, the connecting element is provided on its housing part with a releasable cover part, which can be closed and caught afterwards. A precise length adjustment of the rods is possible by rotating the connecting element.
