After several years of development work the work also accepts Mannheim for the building of aircraft engines. This and the facilities of a repair work require a clear expansion of the work. A second decisive innovation is been carried out another expansion the foundation of the education department in the year 1916. of the opening of the teaching workshop up to the year 1975 in the first year of war 1914/15. are 3424 skilled workers trained here. 1953 the Daimler-Benz AG also introduces the trade school lesson in the work.

Mannheim diesels

One of the most important innovations of the post-war era at Benz & Cie. was its work on vehicle diesel engines. The fundamental principles of this new technology were developed by the diesel pioneer Prosper L’Orange, who joined Benz as head of engine testing in 1908. He discovered the principle of pre-chamber combustion in 1909, followed by the invention of the needle injection nozzle in 1919 and in 1921 by the variable injection pump. The first land-going vehicle to be equipped with a diesel engine was also developed in Mannheim: in 1922 Benz & Cie. presented a three-wheeled tractor, developed jointly with Sendling, the Munich manufacturers of agricultural machinery. The two-cylinder Benz diesel engine gave the tractor a power output of 25 hp (18 kW).

On April 14, 1923, following the successful introduction of the diesel pre-chamber principle, Benz & Cie. decided to launch series production of a four-cylinder diesel engine. That same month, production was started on an initial series of ten units; by late August the engines were ready to be fitted to the chassis of the Benz five-ton truck. The OB 2 model initially developed 45 hp (33 kW) at 1000/min. The world’s first diesel trucks were used, among other things, as experimental vehicles for transportation at the Mannheim plant. The truck went into series production in 1924 with an increased output of 50 hp (37 kW).

Compression ignition: The Benz OB 2 four-cylinder pre-chamber diesel engine of 1923 was the first commercial vehicle diesel engine from large-scale production.

The possibility of a merger between Benz & Cie. and Daimler-Motoren-Gesellschaft (DMG) with a view to creating synergies had been considered as early as 1919. Economic circumstances in Germany at the time were anything but straightforward, with a large number of car manufacturers chasing the same customers. A joint venture remained an option initially, but after the war Benz & Cie. decided instead to carry out an internal reorganization of its operational units. The Mannheim plant took over responsibility for the production of motorized ploughs and tractors, and in 1921 the company sold off the production of stationary engines at the old plant as an independent entity trading under its own name, Motoren-Werke Mannheim (MWM).

The merger between DMG and Benz & Cie. was completed on June 28/29, 1926. To mark the occasion, publicity material highlighted the combined power of the new brand that had been forged out of the two historic firms: “Germany’s two oldest and largest automotive companies have merged with a view to pooling over 40 years of experience in automotive design, the purchase of raw materials and production equipment and an extensive field organization, and to offering customers all over the world an unbeatable range of passenger cars and commercial vehicles.”
Benz & Cie. brought to the marriage two production locations: the stockholding company Benz & Cie., Rheinische Automobil- und Motorenfabrik, Mannheim, and Benzwerke Gaggenau. DMG transferred operational management of its plants at Untertürkheim, Marienfelde and Sindelfingen to the new company.
One of the new company’s first tasks following the merger was to conduct a clean-up of the two model portfolios. This had an impact on manufacturing at the Mannheim plant, where production of the 10/30 hp and 16/50 hp passenger cars from the old program initially continued under the new brand name Mercedes-Benz, before the new Mercedes-Benz Mannheim and Mercedes-Benz Nürburg models superseded these vehicles from the Benz era. The design office for passenger cars and the corresponding test facility were moved from Mannheim to the new company headquarters in Untertürkheim.
Marriage of laurel wreath and star: The companies Benz & Cie. and Daimler Motoren Gesellschaft merged in 1926. This advertisement is to promote the joint sales organization, which was established as early as 1925.

Tractors built at Mannheim also received the new name: in May 1928 the first few units of the new Mercedes-Benz OE diesel tractor rolled off the production line at the Mannheim plant. Offered as a vehicle for road and agricultural use, the tractor featured a water-cooled, horizontally mounted one-cylinder diesel engine that worked on the pre-combustion principle. Output of the large, 4.2-liter, single-cylinder unit was 26 hp (19 kW), achieved at just 800/min.
