Intake and Exhaust Valve Diameter

[tanito87]

Hi, is this a possibility? Allowing us to change the diameter would cause power improvement, or better MTBF on lower diameters.

This is pretty much the same than any other engine suggestion. Read up on some other engine related topic, the FAQ or such, it pretty much sums this up:

- Engine designer is on lockdown until a beta of the full game is released (so enginedesigner (done) cardesigner(almsot done) and tycoonpart(still to develop)
- The engine designer is already complex as it is now. Besides, these things you suggest would add too little gameplay, making it more complex, thus not being worth the time to invest.
- I believe these valve things are already taking into account with the Cam profile slider. Basically the Cam Profile Slider is doing a couple of things at the same time, without making it too complex to understand for non-car enthousiast and greasemonkeys.

Hope I answered your suggestion in a correct manner understandable for you.

I dont completely agree with with that as valve float from my understanding is caused by a car with too small of valves either trying to rev high or too small of a valve spring is in place. So if by what you are saying is true, when we get the warning for valve float in the engine designer we should be able to up our cam profile to fix the problem.?

this is both an honest question and educational objection as I want to learn how I am supposed to stop that annoying valve float warning without having to change my entire head lay out, ie direct OHC to duel overhead cam

Valve float is caused by the inability of the spring to keep control of the valve because of a combination of:

Overly heavy valves
Too light springs
Too many RPMs.

The solutions in Automation are:

More cam profile. (This is assumed to adjust valve springs to match)
More head quality (this is assumed to include lighter valves etc.)
Smaller bore (Makes lighter valves)
Higher number of valves per cylinder (Smaller & lighter valves for the same bore)

thanks for clearing some of that up for me, I can understand as to why they dont want to over complicate it but it just seems like you have to sacrifice alot to get that one issue to go away if you know what I mean. i may have to try lowing bore size next time I see it.

thanks

Yep, once the bottom end is strong enough, valve float is one of the major real life limitations (along with getting enough air to flow into the bloody thing) to get high RPM out of a motor.
