Utilizing the Jones Cam equation with the Piston CFM Demand and Potential VE% theory, Controlled Induction 2020 version 2.01 is our most accurate and powerful design software.  After entering the correct engine data and desired peak HP RPM, Controlled Induction 2020 will automatically calculate the available VE% values from the allowable mean and maximum port velocities and design the camshaft that will produce these values.  


You can generate and save your engine's cam requirement profiles in an "S96" format, which can then be loaded into Dynomation and/or Engine Analyzer Professional software to simulate and verify your cams performance.  With all of the correct input data, you will determine the correct valve size, throat diameter, average port area and camshaft, the first time and every time you model an engine.  With version 2.01 your I.R Roller profiles can be smoothed with polynomial segments to increase the Inverse Radius to a 10" minimum negative radius of curvature to allow any CNC grinder to produce your camshafts from the saved .S96 files.

THE PROFILE PART EDGE DRAWING FORM      


NOT MUCH TO THIS.  AFTER CHECKING THE MINIMUM RADIUS ON THE GENERATION FORM, YOU CAN SELECT "DRAW PROFILES" AND THIS FORM WILL APPEAR AND DRAW YOUR PROFILES.  YOUR LIFT TABLES CAN BE DRAWN AS FLAT TAPPETS OR ROLLERS BY SELECTING THE INDICATED BUTTON AT THE TOP, CENTER OF THE FORM.  THE NOSE RADIUS VALUES FOR THE FLAT TAPPET PROFILES WILL ALSO BE CALCULATED AND DISPLAYED ON THIS FORM. 


ANYONE CAN DESIGN THEIR OWN CAMS, GENERATE PROFILES AND CNC GRIND CAMS WITH CONTROLLED INDUCTION 2020 V2.01. 

ABOVE IS THE PERFORMANCE SCREEN


ATMOSPHERIC CONDITIONS INCLUDING AIR DENISITY ARE CALCULATED FROM OBS. BAROMETER, DRY BULB AND WET BULB.  BSAC, REQ CFM, REQ VE, BSFC AND THERMAL EFFICIENCY ARE CALCULATED IN THE FUEL ENERGY SECTION.  RESONANT TUNING LENGTHS ARE CALCULATED FROM THE SPEED OF SOUND AT THE GIVEN INLET AND EXHAUST TEMPS, AND THE TIME BETWEEN THE OPENING AND CLOSING EVENTS OF THE INDICATED VALVE AT THE GIVEN RPM.  UNDER BLOWN CONDITIONS, THE TEMPERATURE AND CHARGE DENSITY OF THE GIVEN "M.A.P." IS CALCULATED FROM THE GIVEN COMPRESSOR AND INTER COOLER VALUES, ALONG WITH THE REQUIRED CFM FROM THE GIVEN ATMOSPHERIC CONDITIONS.


DISPLAYED IS THE AVERAGE, PREDICTED AND POTENTIAL VALUES FOR OBSERVED AND CORRECTED, TORQUE AND BHP.

THE CAM PROFILE DATA SHEET  (POLYDICK ROLLER PROFILES)   


ALL OF THE POLYDICK ROLLER PROFILE DATA IS LISTED ON THIS FORM.   WHEN SAVING THE "S96" FILES, THE SOFTWARE ALSO SAVES A DATA SHEET FILE (*.DAT) AND A *.PGD" FILE CONTAINING LIFT, VELOCITY, ACCEL AND JERK (SHOWN BELOW).  THESE PROFILES HAVE  DYNAMICALLY SOUND VELOCITY, ACCELERATION AND JERK VALUES, WHILE KEEPING THE SHAPE AS CLOSE TO THE ORIGINAL INVERSE RADIUS PROFILES.  COMPARE THE BEFORE AND AFTER LIFT CURVES IN THE GRAPH DISPLAYED BELOW.


ANYONE CAN DESIGN THEIR OWN CAMS, GENERATE PROFILES AND CNC GRIND CAMS WITH CONTROLLED INDUCTION 2020 V2.01. 

ABOVE IS THE CONTROLLED INDUCTION 2020   "MAIN FORM"


All of the calculations for the camshaft requirements are accomplished here.  Most of these input values are basic knowledge, supplied by the component manufacturers or physically measurable.  After entering your engine data, you simply click on three buttons, or follow the step by step instructions that will guide you in determining the correct values to enter for "Throat Boundary Layer", "Max Allowed Throat fps", "Mean VE%" and the "Curtain Velocity Adjust".

ABOVE IS THE GRAPH FORM


NAVIGATING TO THE GRAPH FORM LOADS TWO SETS OF THE CALCULATED REQUIRED VALVE MOTION, 1 FIXED AND 1 ADJUSTABLE.  YOU CAN ADJUST THE DURATION, LIFT AND AREA OF THE CURVES, AND COMPARE THE GRAPHS, OPENING AND CLOSING EVENTS @ .050" OR SEAT, TOTAL PROFILE AREA AND THE OVERLAP AREA. 


THE SOFTWARE WILL USE YOUR ADJUSTED INTAKE AND EXHAUST LIFT PROFILES WHEN YOU GENERATE THE "*.S96" CAM LIFT TABLES FROM THIS FORM 



Controlled Induction

THE CAM FILE GENERATION FORM         


WITH THE LOBE INFORMATION LOADED AND DISPLAYED, SELECT F.T., I.R. ROLLER OR POLYDICK ROLLER AND ENTER THE CORRECT CAM JOURNAL DIAMETER,  PRESS THE "CALC BC" BUTTON TO CALCULATE THE MAXIMUM BASE CIRCLE DIAMETER, OR ENTER YOUR OWN BASE CIRCLE VALUE FOR CLEARANCE PURPOSES, ETC.  ENTER YOUR ROLLER LIFTER'S WHEEL DIAMETER AND CLICK ON THE CHECK ANALYZE PROFILE DESIGN BUTTON.  VALUES WILL BE CALCULATED FOR MIN RADIUS OR F.T. PROFILE FOOTPRINT.


WHEN THE PROFILES MEET THE REQUIREMENTS, THE GIVEN "GENERATE S96 FILES" BUTTON WILL BE ENABLED FOR YOU TO CLICK ON.  THE SOFTWARE WILL THEN GENERATE YOUR ENGINE SIMULATION AND CNC READY FILES.  THIS FORM CAN BE ACCESSED ONLY FROM THE MAIN FORM.  WHEN THE "PD" ROLLER OPTION IS SELECTED, YOU WILL SEE A MINIMUM "NROC" ABOVE 9.980" FROM THE POLYNOMIAL SEGMENT SMOOTHING.
