摘要:
A fuel supply system for supplying fuel and for satisfactorily preparing the fuel-air mixture fed to a mixture-compressing, spark-ignited internal combustion engine which comprises an arbitrarily operable throttle element arranged in the air intake manifold wherein fuel can be supplied upstream of this throttle element. The throttle element is mounted on a rocking lever connected to a bearing shaft arranged outside of the air flow at the air intake manifold and is displaceable in the opening direction during full load and at higher speeds against the force of a compensating spring until the throttle element comes into contact, with a full-load stop, with the rocking lever. During full load and at low speeds, the compensating spring displaces the throttle element in the closing direction so that a rather large pressure drop occurs at the throttle element so that an improved conditioning of the injected fuel is obtained. A resilient member, engaging via a compensating lever on the bearing shaft, serves to compensate for the opening moment effective at the throttle element due to the air pressure drop. The resilient member is under the effect, on the one hand, of the air pressure in the air intake manifold section downstream of the throttle element and, on the other hand, of the atmospheric pressure or the air pressure upstream of the throttle element with a resetting spring effective on the throttle element.

Process for the preparation of granules by spray-drying of an aqueous suspension having a solids content of greater than/equal to 30% and containing at least one dye, fluorescent brightener or photoactivator and one condensation product from naphthalenesulfonic acid and formaldehyde and, if necessary, further auxiliaries and/or diluents. The spray-drying is carried out at a feed pressure of 50-150 bar, the residual moisture content of the product is less than 4%, and the granules obtained are in particular very pressure resistant and abrasion resistant.

A plug-in device according to the prior art has a spring arm, which presses a knob of the unit plug (3) into a cutout of the socket part. This can lead to a mechanical failure of the spring arm. A plug-in device (1) according to the invention has a knob (9), which is disposed on an elastic part of the unit plug and in the connected state, is held in the cutout (11) of the socket part (5) without external force. The unit plug is locked into the socket rotation of the unit plug (3) to a position where a bump (9) snaps into the cutout (11).
摘要:
A temperature sensor is proposed which is intended in particular for measuring the temperature of the air aspirated by an internal combustion engine which operates by electronic fuel injection. The temperature sensor includes a carrier body receiving electrical connections and a temperature-dependent electrical resistor element which is surrounded by a protective sheath. The protective sheath has apertures which permit free access to the temperature-dependent electrical resistor element by the medium to be measured. The protective sheath is advantageously capable of being connected in a positively-engaged manner with a protruding catch of the carrier body. As a consequence of the free access of the medium to be measured to the temperature-dependent electrical resistor element, a very short response time on the part of the temperature sensor to changes in temperature is assured.
