Camshaft Design & Profile Generation Software

Controlled Induction

( Jones Cam Design Equation )

THE CAM FILE GENERATION FORM         ( ONLY ON FULL CAPABILITY PROGRAM )


WITH THE LOBE INFORMATION LOADED AND DISPLAYED, SELECT ROLLER OR F.T. 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 NEGATIVE RADIUS OF CURVATURE BUTTON.  VALUES WILL BE CALCULATED FOR MIN RADIUS AND F.T. PROFILE FOOTPRINT.


WHEN THE PROFILES MEET THE REQUIREMENTS, THE "GENERATE S96 LIFT TABLE 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 FROM THE MAIN FORM OR GRAPH FORM.  ACCESSING FROM THE MAIN FORM WILL GENERATE THE CALCULATED LIFT TABLES, AND ACCESSING FROM THE GRAPH FORM WILL GENERATE LIFT TABLES FOR YOUR ADJUSTED PROFILES.

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.  Your professional porting shop can supply you with accurate Port CFM values.  The step by step instructions will give you values to enter for "Throat Boundary Layer" and "Set Choke fps".  This will leave you with the two input values having the greatest affect on the cam design.  In one of the three step by step methods, Controlled Induction 2020 will determine and enter those values for you with a click of the mouse.  The other two methods have you manually adjust one of the remaining input parameters until two specific calculated values meet a certain criteria.  


>>>>>>>> All parameters have individual pop up help with descriptions, explanations of use, and acceptable value ranges for input parameters.

Controlled Induction 2020  is our most accurate cam design software to date, and has the added ability to generate "grind ready" lift tables.  The software does it all and is easy to operate with simple step by step instructions, specific to the engine's port type and mean piston velocity.  You will find more help in this software than any of our previous programs, and it includes the range of accepted values for input parameters, instructions, explanations and a few related formulas.


You do not need to know how Controlled Induction 2020 works to use it successfully, but if you pay attention to the values that are affected by changes made to input parameters, and read all of the help, the parameter relationships will become obvious to you.  Spend some time looking over Controlled Induction 2020's many forms and program information displayed below.  White boxes are inputs, Blue and Red are calculated.


DESIGN YOUR OWN CAM, GENERATE YOUR OWN PROFILES AND HOWARDS CAMS WILL BUILD THEM FOR YOU.

THE PROFILE PART EDGE DRAWING FORM         ( ONLY ON FULL CAPABILITY PROGRAM )


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 AND GENERATE I.R. PROFILES WITH CONTROLLED INDUCTION 2020.  AND HOWARDS CAMS CAN PRODUCE THEM.    WHAT ARE YOU WAITING FOR?

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.

ENGINE MODELING & CAMSHAFT DESIGN SOFTWARE

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
