Actros is the name for truck series of the mark Mercedes Benz of the DaimlerChrysler AG.
As successors of the "heavy class" (SK) the imported Actros was not only a new model row, but in many technical details a completely new vehicle. As a successor of the "SK" it "weight class new" was also called, briefly SKN.
To the innovations belonged:
All Actrosmotoren would fulfill at the beginning the euro 2 exhaust standards, later also to euro 3. For the first time the new series 500 used in the Actros received the designation "COM 501 LA" for the 6 cylinders and "COM 502 LA" for the 8 cylinders. COM stands for oil engine, "L" for load air cooling, "A" for loaded, thus with turbocharger.
All series were conceived in such a way, which for nearly all engines, all the same which achievement, partial equality exists. Different engine performances are produced almost exclusively by changed software in the engine expensive equipment.
The following motorizing were offered:
V 6 engines COM 501 LA
460 HP of variant in the engine program one took only later
V 8 engines COM 502 LA
Again with this series also the fuel injection is according to "pump line nozzle" (PLD) the principle. Here each cylinder has its own injection pump by its own cam on the cam shaft is propelled. The fuel system of the pumps is made by a mechanically propelled feed pump. In the return of the injection pump is an electromagnet, which is headed for by the engine regulation (MR). Thus the MR can determine depending upon operating condition start of injection and injecting duration. The injection pressure is then mechanically developed. The injection nozzle opens at approximately 300 bar, the maximum injection pressure lies at up to 1800 bar.
The Topmodell of the Actros series is the Actros BlackEdition. It is limited on 250 units. This model captivates by Interieurs (Vogelaugen-Ahorn, leather steering wheel, coverings also in-punched Mercedes star.).
