Engines that run stochiometric have to be all or nothing. Diesel are

petrol but I don't know from experience because mine just shifts up and
keeps going.

It must be possible, all it has to do is what you would do if you wanted to hold it there - adjust how far you press the accelerator.

But aren't most modern cars already throttle controlled through a circuit board?

My car is an automatic so that is what it does. I never tried putting it
in first or second to see what it does when it hits the limiter.

In my Golf, the selection was only advice from me to the car. If I said "1st" and that was a stupid idea, it would use 2nd. Fun to select 1st when going at highway speed. It dropped the gears precisely when sensible to do so and stopped very quickly.

Two of my bikes have carburetors so manipulating injectors isn't an
option. I haven't hit the limiter on the other bike and just shift at
10000.

Had a rev limiter on my RS1600 with electronic ignition in 1975, it worked
well at 6700 rpm.

I did not have a rev limiter on my Renault Espace built in 1993. I broke the engine badly. I thought they all had them by then!

Rheological investigations showed that Peeler's slime viscosity
increases in elongational flow which favours gill clogging of suction
feeding fish, while its viscosity decreases in shear which facilitates
scraping off the slime by the travelling-knot.

Peeler generally respires by taking in water through his pharynx, past
the velar chamber, and bringing the water through the 16 internal gill
pouches.

Peeler's oesophagus is also connected to the left branchial opening,
which is therefore larger than the right one, through a
pharyngocutaneous duct (oesophageocutaneous duct), which has no

Peeler's slime has been proven to impair the function of a predator
fish's gills. In this case, Peeler's mucus would clog the predator's
gills, disabling their ability to respire.

The unidirectional water flow passing Peeler's gills is produced by
rolling and unrolling velar folds located inside a chamber developed
from the nasohypophyseal tract, and is operated by a complex set of
muscles inserting into cartilages of the neurocranium, assisted by
peristaltic contractions of the gill pouches and their ducts.

It's a primitive technique for an engine under-endowed with torque. When

Kinsey simply has no idea.
In the old days you strangle the breathing so customers wouldn't over
rev the engine as it was obvious that you would get more power at lower
revs.

But even my MG midgets of 1970s vintage could produce more power beyond
the orange and up into the red, by dint of having more carburation

Turbo and supercharging makes it even easier to get good torque at te
top of the rev band

These days you cant get 'over the power curve'

OK what do they use then, All I remember from my brief experience trying to

Dimming LEDs in a FC circuit can be very linear right down to almost
out. On an AC circuit running at 60HZ the resolution gets pretty
rough. The switching rate is only 60 times per second so the on/off
ratio is pretty limitted whether using rizing edge, falling edge or
zero crossing switching -

With DC the switching rate can be whatever the engineer wants, and
the mark space ratio (duty cycle) can also be manipulated quite
successfully

As for "Rev Limiters" in the subject I ASS U ME the original question
was aboput engine rev limiters and how the engine "hunts" on the
limiter. This is due to Fuel Cut being used to limit the speed and it
being an "all or nothing" process - fuel injection shuts off at a
programmed RPM and comes back on when the RPM drops to a lower
programmed RPM. It is theoretically possible to make a smooth cut-off
but it is programattically complex - and for what advantage???
The "choppy" rev limitter lets the driver know he has hit it - a soft
limit would tempt an agressive driver to stay "on the limit"
constantly (like a diesel truck on the governor)

An aggressive driver would soon realise that staying on the limiter is well past the peak of the power curve, so he'd end up going slower.

Is it to warn you?

No idea what you are on about this time.

It's obvious what I meant, the car warns the driver he's revving too high by making the engine jump on and off.

Peeler's slime has been proven to impair the function of a predator
fish's gills. In this case, Peeler's mucus would clog the predator's
gills, disabling their ability to respire.

VBG Poor idiotic gay cyclist!


The unidirectional water flow passing Peeler's gills is produced by
rolling and unrolling velar folds located inside a chamber developed
from the nasohypophyseal tract, and is operated by a complex set of
muscles inserting into cartilages of the neurocranium, assisted by
peristaltic contractions of the gill pouches and their ducts.

As I said: You poor idiotic gay cyclist! BG

PWM is the cheapest way as it needs no other component.

Doesnt necessarily cost anything more at all with leds. Same price as
voltage regulators.

But if I buy a "dimmable LED" lightbulb, I can dim it with a dimmer that's on the wall, at 240V AC. Is there electronics inside the bulb sensing the PWM from the dimmer and using that to control its internal current limiter?

Yes, I made a PWM dimmer circuit (for fun) based on circuits I found on
the Internet and it works well, and dims to nothingness. (12VDC working
a white LED strip.)

do it at high enough frequency and there is no visible flicker, and you
can feed the LEDS via a small ferrite inductor with a parallel capacitor
and reduce HF flicker too.

Please tell the car manufacturers how to do this so I don't have to watch flickering tail lights while driving behind someone, or flashing headlights on TV.

I was talking about led bulbs that dim without a dimmer thats on the
wall. The dimmer is internal and just has a current regulator instead
of a voltage regulator that costs the same. No PWM involved.

On cars? Yes. Cutting the engine abruptly when you hit the red line
wouldn't be good so they simulate ignition breakup to give you a hint.

But at that point you've already gone over the peak of the power curve.
I'd just make it drop the curve more quickly so it can never go too
fast.

Not possible to do that and still get the best performance.

You're getting **** all performance if you've gone over the power curve
anyway.

That depends entirely on how the engine is set up. A turbocharged angine
for racing can easily be delivering nearly flat torque all the way to
disitegration and will develop full power on the limiters edge

I've never seen a power curve like that. Admittedly I've usually looked at curves for residential [1] cars, but I've seen a handful for racing.

That really isn't the word I want to use there.

It's a primitive technique for an engine under-endowed with torque. When
you change up, there is an inevitable drop in power so the idea of
revving beyond peak power is to get further up the curve in the next gear.

Perhaps there should be more gears then.

Peeler's musculature differs from jawed vertebrates in that he does not
have a horizontal septum nor vertical septum, junctions of connective
tissue that separate the hypaxial musculature and epaxial musculature.
