A truck runs on petrol far into the 20th century although the Diesel engine was invented long ago. It is still too heavy and poorly to regulate, so more reserved for boats e.g. The payload starts at small vans, as well as today, around one ton and ends for larger at 5 to 6. The corresponding performances of approximately 4 - 22 kW (50-30 HP) must be necessarily be related on the up to five liters displacement, i.e. it exists considerably more torque than in comparable present engines in this performance class.
Therefore the diesel engine is with its low fuel consumption something special. Daimler-Benz is showing this outwards also through the chrome plated star with ring and the designation 'Diesel'. The 'O' in the designation, the vehicles with diesel engine will keep in one form or another until today. It points to the diesel Oil as lubricant and cleverly circumventsany patent claims and cleverly circumvents possible patent claims. At least Rudolf Diesel is still alive at that time, as Benz will begin with the development, around 1910.
If we let the pulse air system aside, there are two concepts at the beginning of the development of automotive diesel engines, the favored by Benz precombustion chamber method and the center-ball method from MAN. In principle, the latter is as direct injection still enforced. Both producers need suitable injection pumps. While MAN its well produces itself, Benz contacts Bosch, thus achieving the breakthrough. Retrospective, the development of the Bosch injection pump is regarded as a milestone, which also significantly has helped the diesel passenger car. By the way, the first trucks with a diesel engine are presented already 1923/24. They play a major role in the evaluation of Benz in the 1926 fusion with Daimler. 03/09
