Dynomation-5 Engine Simulation


COMP Cams™ Lobe-Profile Library

Motion Software's Lobe-Profile Libraries mark another FIRST for the performance industry! Until now, the only way you could obtain lobe-profile data was to purchase the cams you wanted to test and measure the lobes in a fixture by hand! Not an easy or inexpensive process! But now, you can add hundreds of precise lobe-profiles to your cam library. Not only that, our inexpensive Lobe Libraries includes spreadsheets that provide detailed lobe specifications, application recommendations, and cross-references to cam catalog part numbers!

Motion Software is dedicated to keeping Dynomation users ahead of the competition! Get the most from our powerful engine simulation. Now, with Lobe-Profile Libraries, Dynomation users can model valve motion and engine output with unprecedented accuracy!

The COMP Cams™ Lobe-Profile Library: Motion Software and COMP Cams have joined forces to offer engine enthusiasts 1700+, state-of-the-art, cam-profile files that you can instantly load and test in Dynomation-5! The profiles on this disk were obtained directly from cam-manufacturing data, so there were no set-up errors, run-out issues, or other measurement “anomalies.”

These profiles allow Dynomation-5 to precisely simulate valve-motion, an essential step in obtaining the highest accuracy in engine modeling.

The entire COMP camshaft lineup can be simulated using the lobe-profile data is this library. Not only can you load and test all existing COMP cam lobe profiles, but you can mix and match lobes for all-new designs, and even test “experimental” profiles! When your simulation testing is completed, COMP can quickly turn any lobe combination (within reason) into a real camshaft for any engine!

Simply put, if you want the highest modeling accuracy in Dynomation-5, this Lobe-Profile Library will be a priceless addition to your engine design tools.

How To Use Lobe Profiles: Lobe-Profile data gives Dynomation-5 users substantial new advantages in engine testing and development. Lobe-profile data consists of 180 or more data points measured directly from each cam lobe. Since airflow into and out of the engine typically is very sensitive to valve position, especially at low valve lifts, accurate valve-motion data is an essential element in precise engine modeling. Lobe-Profile data ensures the highest valve-motion precision within Dynomation-5.

Importing profile data from a library takes only seconds. Pressing the Import Lobe Profile button in the Camshaft category opens the Lobe-Import Dialog, shown here:

Lobe Source-Data List—A list of lobe data sets within the selected Lobe-Profile file are displayed in the top-left Source Data list.
Lobe Duration—Here you check LOBE duration at various lobe-lift points. Values shown here should match the data in the accompanying spreadsheets.
Lobe-Rendering—The lobe-profile image is rendered from the data recorded in the file. Use this image to confirm the general validity of the data set.
Lobe-Data Destination—The lobe data can be assigned to either an intake or exhaust valve using the "radio buttons.".
Lobe Centerline—Set the Lobe Centerline. This indicates the rotational index, in crank degrees, from the center of the lobe-profile data (point of maximum lift) to the Top-Dead-Center piston position. The Lobe Centerlines can be changed at anytime after the lobes have been imported.

What You Can Do With Lobe-Profile Libraries:
  • Easily Import Lobe Data Into Dynomation-5 Through Versatile Lobe-Profile Import Dialog

  • Apply Any Lobe To Either Intake Or Exhaust Valve

  • If You Are Using Dynomation-5 To Simulate Variable-Valve-Timing (VVT), You Can Import Any Lobe To Either Low Or High Speed Cams

  • Change the Intake or Exhaust Centerlines Before And After Importing The Lobe Profile

  • Change the Valve Lash and Rocker Ratio Anytime After Importing The Lobe—The New, Effective Duration Will Be Calculated.

  • Maintains The Highest Modeling Accuracy

  • Transform Lobe-Profile Data to 10-Point Data At Any Time To Allow Valve-Event Timing Changes/Testing (download the QuickStart guide for more information on using 10-point timing).

  • Use Rocker-Math Calculator With Profile Data To Determine Effects Of Lash And Rocker-Ratio Changes.

  • Test Production And Experimental Lobes; Optimize Engine Performance, Map Sensitivity To Timing Changes, Much More!

  • Find The "Sweet Spot" For Any Engine Application
