F4 Engine Data required for WAVE simulation

[Gary]

Hey Guys,
I have been in SAE since 2001 and have been designing the intake using helmholtz techniques. Now in my thesis year, i just recently received WAVE by Ricardo to aid in the design of the intake and exhaust for the CBR 600 F4. However, i am finding it really hard to locate data on the engine required to run the simulation such as: profile of lift vs crank ange, valve lift, seat diameters etc. If you could please help out a fellow sae student i would really appreciate it and will provide info in return to the best of my ability. thanks guys

Gary,
You might want to check e-bay for an owners manual or a mechanics manual for the F4 engine. There within you will find the majority, if not all, of the information you need to model your engine. That's the route I took for modeling a 1999 Yamaha YZF600R and my analysis was fairly accurate.

We use Cam Pro Plus on our cams to do all that stuff. Unfortunately, we've got a GSXR, so I can't help you with numbers. You're going to have to pull apart the head to measure some of those things if you can't find them in print. I suspect you won't be able to find them in any Honda publications.

Put it on a mill with an indicator, and indicate it.

thanks heaps guys for your advice. I have put on order the OEM Honda CBR 600 F4 manual to get the valve dimension data, valve timing, max lift etc. Hope its all in there. As for the valve profiles and discharge coefficients we may have to set up a flow bench and buy a wrecked head to use in the experiment. Our supervisor is very stongly set on not opening the engine that we use so we can't go against that. Does anyone have any flow data that we may compare against that has volumetric flow rate and pressure drop across valve? We have never set up a rig before so it'll be good to get some reference off some one who uses a comercial flow bench. Thanks for all your help. http://fsae.com/groupee_common/emoticons/icon_smile.gif

Not opening up the engine? WHY?! The head takes like 10 minutes to take off! Unless you have someone grinding in the same area you'll be ok.

Then again, getting a trashed head is going to be about as easy. It comes down to the cost of a head gasket versus the cost of a head.

Yeah, I'll have to agree with Twig. Day one here the freshman tear into an engine and it has to run by the end of the quarter. Why the fear of opening up the engine? Is the supervisor afraid of jeopardizing reliability? Is the supervisor a student or faculty? I would like to do some simulation in WAVE but only if I was allowed to do the fun stuff too (like play with real engines).

With that said, I would come up with another head so you don't hinder engine development.

By the way Twig it finally ran (limped) on Friday
