Development

Most newer DB engine designs used in WW2 were based on this engine. The RLM made a set of specifications listing the technologies which the new class of German aero-engines required. Among these items was

s. Knowing that this would take some years to implement, the RLM permitted that the manufacturers could first design and produce the basic engine, and later develop it to include the injection system. The DB 600 formed this function (having in turn been developed from the Daimler-Benz F4A and F4B V12s), therefore when the injection system was ready it meant that the DB 600 was replaced by the otherwise similar DB 601, which in addition to direct fuel injection, also added the variable speed supercharger. Later DB series engines grew in
