摘要:
Internal combustion engines utilizing conventional carburetors have auxiliary devices such as a choke and accelerator pump which cause over-rich mixture and consequently affect the fuel consumption and exhaust gas emissions adversely. The present invention improves the performance of such engines whilst retaining the advantages of conventional carburetors.The invention provides a spark ignition carburetor equipped engine with an electromagnetic injection valve disposed in the induction manifold for the supply of additional fuel when required. Actuation means for the electromagnetic injection valve are preferably electronic devices which comprise a pulse generator and measured valve transmitter (sensors) for each of the engine operating parameters relevant to the injection of additional fuel, thus the timing and duration of opening of the injection valve is controlled precisely.

Divided flywheel arrangements having a spring arrangement, and preferably also a slip clutch arrangement, accommodated in a lubricant bath, which is formed by an annular space limited radially outwards only by parts which are stationary relative to one another. Centrifugal forces acting on the lubricant cannot therefore force the lubricant against seals between mutually movable parts. Certain disclosed arrangements do not accommodate these parts in a lubricant bath.

The flywheel elements are connected to one another in drive terms via a spring mounting, an abutment of which is movable relative to the associated flywheel element against the resistance of a second spring mounting and a non-positive coupling arranged parallel to the second spring mounting. Furthermore, a second non-positive coupling, subject to play, is connected between the flywheel elements and is limited resiliently in at least one direction.

Apparatus for collecting soot from soot-laden exhaust gases flowing in an exhaust gas line of an air-compressing compression ignition engine comprises a housing adapted to be incorporated in said exhaust gas line and to be flown through by said soot-laden exhaust gases; baffle walls contained in said housing and arranged to repeatedly deflect the exhaust gases flowing through said housing and to cause soot to be separated from said exhaust gases and to deposit at least in part on said baffle walls; and an accumulating container disposed under said baffle walls and arranged to receive soot which has been separated from said exhaust gases at said baffle walls. Said apparatus is designed to permit soot deposited on at least part of baffle walls to be removed therefrom and to fall into said accumulating container. Said container is designed to permit soot accumulated in said container to be removed from said apparatus.

When cartridges are introduced into a weapon there exists the danger that the conical shoulder of the cartridge case or sleeve will be deformed to an undesired degree. To avoid such disadvantage the wall of the conical shoulder is constructed to be thicker than the wall of the case or sleeve body of the cartridge case. For producing such a cartridge case an extruding mandrel is used which contains a recess at the region of the conical shoulder in order to generate a region of increased wall thickness in the wall of the cartridge case or sleeve.

This invention relates to an internal combustion engine, particularly to a diesel engine. The engine comprises a crankshaft, which is connected to each of a plurality of pistons by a connecting rod and a piston pin. Each connecting rod has two bearings for the piston pin and a crankpin of the crankshaft, respectively. In order to provide a desired piston clearance between the piston at its top dead center and the bottom of the cylinder head, at least one of the bearings of the connecting rod is provided with an eccentric ring disposed between the receiving bore and the bearing bushing. During the assembling of the engine, the eccentric ring is rotated to such a position that the desired piston clearance is obtained. The bearing ring is then fixed in the resulting rotational position.

There is disclosed an injection syringe assembly comprising a cannula module including a two-part cannula shield device having a separate front cap, as well as a latched-in cannula holder in which a cannula is glued. In the mounted state, a plug-like cannula seal is received in the front cap and the cannula holding means is located forwardly of the syringe cone of a syringe body of an injection syringe. It is indirectly fastened to the syringe cone by aid of an elongated fastening portion of the cannula shield device. The cannula shield device includes two predetermined breaking points in order to be able to recognize immediately unauthorized manipulations at the syringe.
