The Mitsubishi S12R-PTA : powerful and reliable 

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 a newly designed high performance turbocharger and twin passage swirl port, Mitsubishi has achieved an outstanding fuel-efficient engine in the SR series. 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  • Exterior engine piping has been replaced by internal installation of accessories thereby eliminating the possibility of pipe breakage;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.
