  • Page 4: Exhaust System Design

    Sharp exhaust pipe bends close to the outlet increase the risk of hissing sounds. 1200 1500 1800 2100 2400 Graph for determining the longest length of tailpipe. DI09. DI13. DI16. 02:04 Issue 7.0 en-GB © Scania CV AB 2016, Sweden...
  • Page 5 Note: The exhaust back pressure increases with the number of pipe bends and with in- creased pipe length. This leads to higher fuel consumption and loss of power. 02:04 Issue 7.0 en-GB © Scania CV AB 2016, Sweden...
  • Page 6 Examples of short exhaust systems with designs which aid sound reduction. L = Length of tailpipe, determined from graph a = 2/3 of L. Length a is less significant in exhaust systems with only one silencer 02:04 Issue 7.0 en-GB © Scania CV AB 2016, Sweden...
  • Page 7: Connection Of Exhaust System To Engine

    A flexible connection can consist of the Scania exhaust bellows. Position the flexible connection as close to the turbocharger con- nection as possible.
  • Page 8: Exhaust Pipe Bends

    The flange, which is marked in grey in the illustration, is connected with 4 Ø 11 mm screws. Exhaust pipe bend for the DI13 072/077. Exhaust pipe bend for the DI09, DI13 except for 072/077 and the DI16 The flange marked in grey is only used on DI16 XPI. 02:04 Issue 7.0 en-GB ©...
  • Page 9 They have outlets to fit an exhaust gas temperature sensor (1), thread 1/8-27 NPTF. The upper illustration shows an example of a water-cooled exhaust pipe bend for DI09 and DI13. The table gives the measurements for all water-cooled exhaust pipe bends for DI09 and DI13.

  • Page 12: Exhaust Bellows

    The loose flange supplied with the exhaust bellows can be selected with different in- ner diameters for connection to different pipe diameters. Available inner diameters Ø170 (A) are 130 or 155 mm for DI09 and DI13, and 114 and 130 mm for DI16. 0.5±0.05 20°...

  • Page 14: Type Of Exhaust System

    A very short exhaust system can be fully encased in water. If so, no silencer is need- 02:04 Issue 7.0 en-GB © Scania CV AB 2016, Sweden...
  • Page 15: Wet Exhaust System

    The jacketed exhaust pipe is then connected to the board lead through with a rubber exhaust hose. Only corrosion-resistant hose clamps may be used for the rubber hoses. 02:04 Issue 7.0 en-GB © Scania CV AB 2016, Sweden...
  • Page 16 Design the water intake to the rubber hose so that the spread of water over the surface of the hose is assured even at low engine speeds when the sea water flow is also low. 02:04 Issue 7.0 en-GB © Scania CV AB 2016, Sweden...
  • Page 17: Insulating The Exhaust System

    An insulated system can increase the noise level at the outlet. This should also be considered when determining the measure- ments. Values for insulated exhaust systems can be found in 02:06 Technical data. 02:04 Issue 7.0 en-GB © Scania CV AB 2016, Sweden...
  • Page 18 Design the insulation so that the flexible part of the exhaust system is not restricted in its movement. It must also be possible to inspect the exhaust system without dam- aging the insulation during dismantling. 02:04 Issue 7.0 en-GB © Scania CV AB 2016, Sweden...
