AIR INLET SYSTEM
4.2.4

HOSE CONNECTIONS

Use the following for hose connections:
□ Plain (non reinforced) hose sections to connect items of rigid pipework which are in line
and close together, or have little relative motion.
□ A short section of reinforced hose between the ductwork sections where significant relative
motion or misalignment occurs. High quality "Hump" hose is capable of meeting these
requirements.
□ Spring loaded clamps to provide positive clamping and to prevent piping separation.
DDC does not approve the use of plain bore hoses with internal coil spring insertions.
Plain hoses used in the inlet system must be of adequate specification to withstand service
conditions. The basic requirements are listed in Table 4-3.

DESIGN GUIDELINES

The installed inlet system must be designed to supply clean, dry, cool air to the engine with
minimum restriction. The system must also provide reliable sealing, durability, and require
minimal maintenance.
Never allow the turbocharger to support any weight of the air
intake system.
The main design criteria for the air intake system includes:
□ Maximum air inlet flow
□ Air intake restriction
□ Inlet location
□ Temperature rise from ambient to turbo inlet
Refer to section 14, "Technical Data," for limits on each of these criteria for your specific engine.
