DIESEL ENGINE GUIDE
| This step by step guide has been developed to assist in selection of the proper CENTRI® Air Precleaner for use on the diesel engine. By following these steps the correct sizing will be obtained:
1. Determine engine displacement in Cubic Inch Displacement (CID) or Liters, and if the engine is Turbocharged, Turbocharged Aftercooled or Normally Aspirated. Consult manufacturer's specification sheet for this information. 2. Refer to appropriate chart based on engine type. (Turbocharged, Turbocharged Aftercooled, or Normally Aspirated) 3. Locate proper operating RPMs at the top of the columns. Then move down the column to the proper CID/Liters. 4. Move across proper CID row to the column, labeled CENTRI® Model. The number in this column will be the CENTRI® Air Precleaner required for the engine. 5. After selecting the proper CENTRI® unit, measure the O.D. of the air intake. If this size is larger or smaller than the CENTRI® unit, refer to the Accessory Page for the adaptor required for installation. CENTRI® unit dimensions can be found on the Specifications Page.

C.F.M. FORMULA
C.F.M.= CUBIC FEET PER MINUTE
For all engines, the C.F.M. can be determined by using the formula below:
|
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
C.I.D.-Cubic Inch Displacement R.P.M.-Revolutions Per Minute Vol.Eff.-Volume Efficiency
To convert Metric Displacements to C.I.D. for use in the formulas, use the following conversion factors:
Displacement in Cubic Centimeters (cm3) x 0.06102 = C.I.D.
Displacement in Liters x 61.02 = C.I.D.
NOTE: Engines equipped with twin air intake pipes, divide the engine C.F.M. by two
and apply the proper CENTRI® Precleaner to each of the pipes.
