DelSolFreak Posted February 26, 2008 Share Posted February 26, 2008 anyone ever heard of the "Coates Spherical Rotary Valve System"(a.k.a. CSRV)? its a cylinder head that has been around for a while that eliminates the need for a poppet valve. its main applications are in industrial equipment. they have built several race engines using this system. and finally there main focus now is to release it to the public. i am currently in the process of getting more info on the CSRV and will give you updateds everytime Coates updates me.

TS John Posted February 27, 2008 Share Posted February 27, 2008 That sounds crazy. More info? Links to what might explain this a bit better? I find it unlikely that this would be made in B-series honda applications, though... Link to comment Share on other sites More sharing options...
delsol209 Posted February 27, 2008 Share Posted February 27, 2008 yea so do they just put it in industrial equipment or are they putting them in factory cars now, and these racer cars how are they doing Link to comment Share on other sites More sharing options...
DelSolFreak Posted February 27, 2008 Author Share Posted February 27, 2008 there not putting them in factory cars yet. i dont have any info on how the cars they are putting them in are doing but ill try to find out. oh and another thing.... there is no coolant or oil flow though them. all friction points ride on ceramic bearings. ill post up a link tonight.

delsol209 Posted February 29, 2008 Share Posted February 29, 2008 thats pretty crazy i wonder when, or if it's going to hit the production line Link to comment Share on other sites More sharing options...
IVhorsemenmotorsports Posted February 29, 2008 Share Posted February 29, 2008 heres the link the thing is was talking bout I have seen this setup a long time ago. It is a very effcient setup which gets rid of majority of the moving components. less friction. You also don't have to run too much oil in the head.It is going to cost alot of money to make this out to the general public. on a side note I have seen the new type of head they are trying to make availible. Each valve is open and closed by a solenoid coil controlled by the ecu. You can make lift and duration changes via computer re-map. I saw this while I was in college.

TS John Posted February 29, 2008 Share Posted February 29, 2008 I've heard about that -- computer controlled valves and all. I actually though BMW was starting to use it but I have no idea why I thought that -- it could and prolly is completely wrong. I don't see why they don't do it like that, though. Seems so efficient.

delsol209 Posted February 29, 2008 Share Posted February 29, 2008 yea but then why do companies put out parts that have a life expectancy of like a certain amount when you know that they can build something that could last forever, i think thats mainly why but then again this thing may not be that efficient Link to comment Share on other sites More sharing options...
