Colt-Pielstick PC2.6B

The Colt-Pielstick PC2.6B is a development of the Colt-Pielstick PC2.6 medium-speed engine. While retaining the same main characteristics, the power rating has increased from 615 kW/cyl to 750 kW/cyl. The ‘B’ engine operates at 600 rpm, with a lower fuel consumption and with the patented MPC (Modular Pulse Converter) supercharging system.

PC2.6B Advantages

  • Capacity to burn all residual fuels
  • High power-to-weight ratio
  • Increased ease of maintenance
  • Same speed for both mechanical and electrical propulsion
  • Economical operation
  • Low overhead height for piston removal & maintenance
  • Water cooled exhaust valves
