why do we still use pressure controlled wastegate actuators?

why havent we ditched them yet,, i would of thought that a electronic linear actuator would of been used by now

just thinking out loud really

 

Gareth, the problems are...

1) HEAT - kills electronics
2) SPEED/STRENGTH - Needs to be fast moving and strong

Could be done completely electronically but you would end up paying LOADS !!!

 

simple effective?

 

Interesting thought though Mr T. As said, heat problems would kill the plan. A remote-activated servo (ie with a rod from the servo to the wastegate) would need a silly long rod to mean the servo could be situated anywhere

 

heeman10,

Problem with servos is it needs to be VERY strong and quick reacting.

Dont forget,, the wastgate must be STRONGER than the highest exhaust gas pressure !!!!

 

Yep, the "if it ain't broke" mentality is probably going to win out on this one!

 

i think it is too,,, for good reason as explained,,

 

Well that was a nice long, brain-tempting discussion!!

 

i still think its possible,, there is many ways too get around the actuators strength,,, like adding a gearbox of somekind, or even making the pivot longer on the wastegate end

 

If it isnt broke dont fix it? Then humanity would never move forward.


I thought i read somewhere that some manufacturers are moving to it?


CAn i ask what im wondering though its nothing to do with cars, and me saying ti could make me look bad as people will think im cruel etc Oh wait forget it

 

i know of someone who makes these already!sells em on ebay!

 

Rhys - Like I say, only applying that to this in particular. I hate that attitude, one I often hear living up here where time stands still!

 

Fook sake take a chill pill mate Only saying

 

the was at the attitude, not at you ya numpty
