MAN Engines has debuted its straight-six, 145-mm stroke, 115-mm bore engine, the MAN D1556, which has applications in agricultural machinery.

  • Features 9.0 L (2.4 gal.) design 
  • Power range from 205-324 kW (279 and 440 hp)
  • Compact and lightweight design, measuring 1,414 × 807 × 1,103 mm (l × w × h; 55.7 x 31.8 x 43.4 in.)
  • Less complex as there is no EGR (SCR only, assisting reliability
  • Control system for the exhaust gas aftertreatment system is fully integrated into EDC (Engine Device Control) 
  • Generates maximum torque value of 1,970 Nm (1,453 ft.-lbs.) between 1,150 and 1,300 rpm 
  • Dry weight of just 860 kg (1,896 lbs.) without exhaust gas aftertreatment
  • Common Rail System provides maximum injection pressure of 2,500 bar (36,259.4 psi)
  • Includes turbocharger with variable turbine geometry (VTG), allowing efficient engine operating range customized to perfectly match wide range of applications
  • VTG turbocharger features compact dimensions compared to two-stage turbochargers and increased brake output without use of additional components such as brake flap or valve brake
  • High compression also ensures more efficient fuel consumption
  • Meets most recent emission requirements such as Euro Stage V and US Tier 4
  • Modular exhaust-gas aftertreatment system consisting of DOC/DPF (diesel oxidizing catalytic converter/diesel particulate filter) and SCR (Selective Catalytic Reduction)
  • For regions with less stringent emissions requirements in line with EU Stage IIIA/IIIB only the aftertreatment's SCR component group is needed
