ABSTRACT:
An oil level regulator for an internal combustion engine, provided with a lubricating oil sump and a starter motor operated by an ignition switch having an ignition lock. An enclosed measuring chamber communicates with the oil in the engine sump, so that the same oil level occurs in the measuring chamber as in the sump. A tank for topping-up oil is connected to the sump by a controllable shut-off device. A level measuring device in the form of a sensor emits an electrical signal as to whether the oil level is correct or too low. If "correct", then the ignition lock is released for a predetermined period, so that the engine can be started. If "too low", a shut-off device is opened for a predetermined period, to allow a certain quantity of oil to the sump, then to measure the oil level again and, if "correct", to release the ignition lock.
