DE2908643A1 - Electromagnetically controlled starter flap for engine - closes flap for starting and then opens to given setting once engine has started - Google Patents

Abstract

The starter flap is operated by an electromagnet located in a circuit designed such that the flap must always open when the engine is starter. The electromagnet is enclosed in insulation. The negative pole for starting is the charging cable of the vehicle's generator. After the engine has starter, the negative pole is automatically changed to the positive pole and the starter flap opens quickly or slowly depending on the setting. The starter flap may also be controlled by a switch. In an alternative version the flap fully closes when the vehicle's starter is operated thereby ensuring starting. Once the engine has started and the starter switch has been enclosed, the flap moves immediately to a given position (dependent on the type of engine).

Description

Electromagnetically controlled starter flap adjustable.

The device listed above will replace the previous automatic start (electrical or water preheated) built in by eliminating the bimetallic spring. By this device will shorten the opening time so that the unnecessary fuel consumption is significantly reduced in short-distance traffic as well as in valley and city trips Circuit 1 of the device takes place as follows: When the starter is actuated The magnet gets the current from the habel 51 on the magnet switch of the starter.

This closes the starter flap completely, so that a flawless Starting process of the engine is guaranteed.

After the engine has started and the starter switch is released the starter flap opens immediately, i.e. after setting the flap to the sensitivity of each individual engine type to about 1/3.

Circuit 2 of the device is done through terminal 61 of the alternator, which is now used as the negative pole during the start-up process. As soon as the engine is running and the alternator is emitting power, the magnet is out of order because the one used The negative pole (connection terminal 61) becomes positive.

The damper in the electromagnet now leaves the starter flap, depending on Adjusting the damper, slowly opening without the driver on the position need to pay attention to the starter switch. Thus, under no circumstances will the opening forget the starter flap.

With vehicle engines that start worse, i.e. those with constant when the starter flap is closed, you can use the switch @ button open either 1/2 or fully, so that there is definitely a decrease in the case of older motors, can be avoided despite several start attempts. By applying the electromagnetically controlled starter valve, an oil dilution is avoided, which leads to a higher Wear and tear and, in the long run, lead to premature failure of the engine.

General: 1 electro-magnetically controlled starter flap adjustable, as a replacement for the previously used automatic starter controlled by Bimotall and can be used for the pre-gas, Kennsoichn @ n @@@ part @ by the fact that the circuit of the electromagnet for actuating the choke is done so is that a failure to open the starter flap during commissioning of the vehicle is excluded. Generic term of the sub-expression: Electromagnetically controlled starter flap after @@ An @ pruch (1). Kenns @@ e. Toil of the claim characterized in that the electromagnet Is mounted insulated from the outside and as a negative pole when starting the engine, the charging cable the alternator is used. As a result, after the engine starts, the Negative pole automatically becomes positive pole and the starter flap opens depending on the setting slow or faster. The switch can be installed separately to regulate the starter flap additionally take place.
