More than years ago, Bosch achieved the breakthrough in modern automotive technology: The world’s first high-voltage magneto was created at the Stuttgart works in This replaced the then commonly used ignition systems such as glow tubes and naked flames. The gasoline engine became more powerful and safer – a real impetus for the automotive industry. On 7th January Bosch were awarded a patent on their spark plug and this marked the start of the success story.

To date Bosch have developed more than 20 types of spark plug. Although the ingenious operating principle of the spark plug developed by Bosch has never changed in the course of years, its performance has steadily improved. Imprint Legal Privacy.

The history of Bosch starts with many first steps. The step into independence, onto the automotive market, into markets outside Germany, and onto the factory floor of major manufacturing. His apprentice and journeyman years awoke an early desire in Robert Bosch to be self-employed. The early years were beset with highs and lows, and it was only from the mids on that things took off quickly and unstoppably.

Bosch performed all the precision mechanical and electrical engineering work that came his way, such as installing telephone systems and electric bells. When asked to build a magneto ignition device for a stationary engine in line with an existing design, he improved this and thus paved the way for magneto ignition production.

The young Robert Bosch did all the precision-mechanical and electrical-engineering work that came his way in order to keep his business running. For the most part, this involved installing low-voltage equipment such as telephone terminals, electric bells, door openers, remote electrical water-level indicators, and later pneumatic tube pipelines and electric lighting. Yet despite this extensive portfolio, orders were often sparse during the early years, leaving Bosch struggling to keep his workforce busy and pay their wages.

This invention concerns an ignition system for an internal combustion engine of the kind powered by a magneto generator that does not require the interposition of a storage battery in the system and incorporates engine speed limiting by intermittent suppression of ignition. A known system of this type is disclosed in German patent publication DE-OS 27 51 in which two monostable multivibrator circuits, commonly referred for short as “monoflops”, connected one behind the other, are utilized for engine speed limiting.

The output of the last monoflop is connected, along with the output of an electronic control apparatus for ignition timing, to the control input of an interruptor switch through an AND-gate.
