Valve profile for an internal combustion engine
 
Hello,

I'm currently working on the Tutorial 12. Cold Flow Simulation Inside an SI Engine.
I don't understand the valve.prof file. when i open it with text editor i have this:
//////////////////////////////////////////////////////////////////////////////////
((ex-valve point 141 1)
(angle
1.119000e+02 1.120000e+02 1.140000e+02 1.160000e+02 1.180000e+02

If somebody can tell me what this file is for ? and what's the meaning of all the angles ?

Thanks.

Where did you find that tutorial? I am interested on that.

This is an input file for defining how valve lift varies with different crank angles.

ansys customer service... you need your account number, otherwise just use google i'm sure you will find some in universities's website

Thanks for your answer,
do you have any tutorial on the 3D internale combustion engine or adiabatic compression ? this will be realy helpfull for me.

Can you Please share me engine geometry as i failed in ciinstructing valve error Mess
 
Hi,

I hope one of get success in cold flow simulation so request to share engine model because i am getting error message in valve sheat i tied a lot for same.

Sir, Can you give information about how valve.prof is created for any engines valve profile.I want to create valve lift profile of TV1 engine.So I can use it in Ansys Simulation of IC Engine.

Thanks in advance.
