Diesel direct injection engines for commercial vehicles

    12 - 22 March 1964
  • Description
    A revised range of commercial vehicles is unveiled at the Geneva Motor Show. The most important new additions are the OM 352 and OM 346 diesel engines, which are the first Daimler-Benz power units to work with a direct injection system and replace the OM 322 and OM 326 pre-chamber diesel engines. The pre-combustion principle – developed at Benz & Cie. – is somewhat smoother-running and thus remains an indispensable component of diesel engines in passenger cars for decades to come. In the commercial vehicle sector, on the other hand, the direct injection concept becomes the dominant force, the many years of development work having generated significant benefits in terms of fuel consumption and mileage.
