Sweden??

oooooo!!!! *Freevalve*....

I'm just waiting for freevalve to finally come to more mainstream cars

Koenigsegg says theyre trying to do that.

That Chinese company Qoros is doing it

NO Cams

eat shit civic ricers

where we are going

we don't need tuning

Yeah, I mean, electronics are definitely responsible for making cars more reliable

I totally want electronic systems controlling valves

what could go wrong?

It's no different than your fuel injection being controlled by a Hall Effect sensor on the crank.

I don't think faulty fuel injection or crank sensors can wreck your engine

It's still mechanically connected, I believe. It's just the individual cylinders can be adjusted. The most that would happen in a failure is some pinging in a cylinder, which would throw a code and put you into limp mode.

Plus while it is electronically cintrolled, its not electric motors or some shit

Pneumatics

Think of it like being able to adjust the spring rate of your rockers

Your computer would have to be either pretty slow or pretty stupid for faulty freevalve to ruin the engine

if it fails and a valve is in the wrong position when the cylinder returns and it has no signal to adjust, the valve will stay in place and it's basically like what happens if a cam belt or chain stretches/snaps, your shit would be fucked

I don't think that's how it works

Besides, dont most modern engines die when that hapoens for that reasin?

the peak reliability of cars seems to have been 80s and 90s depending on manufacturer, electronics since have made cars less reliable, though there's some question whether the increased requirements in efficiency have also contributed to the lower reliability

Reason

It's still a non-interference engine like any other, but instead of ALL the cylinders being adjusted with VV-T, it's individual cylinders

The increased emissions requirements is most of it, i would say.

I doubt the freevalve engine is non interference

Considering yiu still have shit like, fir example, the million mile toyota tundra, cars are at worst just as reliable.

Depending on mfg

very few modern engines are able to be non interference because of efficiency requirements

I wouldnt call a modern fca car more reliable...

I'm not sure if any regular cars on sale are non interference actually

Well, it seems the conversation won't be fruitful and is just some more competitive pissing, so w/e

Most arguments about reliablity become that, really

There isnt a whole lot of hard data on car reliability. Best you have is iffy af surveys

well that's because reliability can often be highly subjective

owners and how they treat their vehicles contribute to failure rates

and it's very hard to adequately monitor that

but in general, the old hilux, a bunch of 80s and early 90s benzes, late 90s jap N/A 4cyls are all ridiculously reliable
