MAXIMUM AIR INLET FLOW

The first step in the design of the air inlet system is to determine the maximum air flow
requirement for the engine. This information for the MBE4000 engines is listed in the "Technical
Data" section of this manual (refer to section 14).
4.3.2

AIR INLET SYSTEM RESTRICTION

Recommended pipe sizes may be used for the initial sizing of the air inlet system. Increase the pipe
size or modify the piping configuration if the air intake restriction exceeds the maximum limit.
An air inlet restriction indicator must be installed on the air intake system.
The restriction of the air inlet system is equal to the sum of the individual restrictions in the
system. These include rain caps, inlet hoods, air cleaners, and piping. See Figure 4-8.

INLET LOCATION

Position the air cleaner inlet so that air is drawn from an area clear of water splash with the lowest
possible dust concentration; an area that minimizes:
□ The temperature rise from ambient to turbo inlet
□ The possibility of exhaust fumes and crankcase emissions being drawn into the inlet system
