LAST REVISION 08. April 2011 2.06.06 DITA (2) revised power output. Adjustment to exhaust gas temps, gas flows
The air velocity over the radiator is 5 m/s for all the C4.4 radiators. The volume flow is 1.53 m³/s for the DINA and DIT engines and 2.48 m³/s for the DITA engines. Maximum duct restriction = 200 pascals
Fan Ratio ( 1500 and 1800 rpm ) 1.25 : 1
