The Mitsubishi S6R-PTA is a very powerful and reliable diesel engine, used in industrial and marine applications. 

Greater power in less space

The Mitsubishi SR-series gives greater power in less space. The SR series consist of 6-cylinder in-line diesel engines, 12 cylinder V- type and 16 cylinder V- type engines. These compact power units require less floor space in a generator set arrangement. They are also lightweight, easy to handle and easy to install.

Extra high fuel efficiency
Experience gained during more than a decade of SB, SA and SN diesel engine production led to the introduction of a direct injection system employing Mitsubishi’s originally designed PS type fuel injection pump.
Now, in combination with an originally designed high performance turbocharger and twin passage swirl port, Mitsubishi has achieved in the SR series an outstanding fuel-efficient engine. Parts like the water pump, fuel pump, injector and oil filter are available from stock.

Unique design

  • Newly designed crankcase and components offer lightweight configuration.
  • Most accessories are concentrated on one side of the engine for easier daily maintenance.
  • Exterior engine piping has been replaced by internal installation of accessories thereby eliminating the possibility of pipe breakage.
  • Cartridge type paper filter facilitates easy filter change.
