Any/all rev limiters I have ever worked with have all been on the spark side of the power triangle ( compression / spark / fuel )
Every car with a rev limiter in then engine ECU accomplishes it by cutting the fuel off. If you turn off the ignition, you continue to blow unburnt petrol vapour down the exhaust, where it will ignite in a spectacular killswitch backfire as soon as the ignition kicks back in. It will also destroy the catalytic converter.
Which makes sense given how some i4 engines can approach the same levels of power to that of a v6.
Most I4 engines in European cars are more powerful than American V6 engines. I mean, Ford are still releasing engines based on the ancient Essex blocks, albeit drilled out to 4 litres, but they're still thirsty, clattery gutless boat anchors. Hell, the I4 turbodiesel in my van is quieter and more powerful than most Yank-tank petrols...
It's a bowl used for washing up (washing dishes) in. It's a Britishism, AFAIK.
I think people wash dishes in most countries. It's a bad idea to do it in the sink directly, because you can chip your dishes really easily. I suspect a stainless-steel washing up basin would have exactly the same problem, which is why people mostly use plastic ones.
Here's a novel idea. I haven't seen anyone do this and it's probably patentable - except by posting here I have prior art;-)
I built a guitar fuzzbox. Plugging in a lead made all kinds of pops and crackles, so I modified the circuit so that when the plug was out it fed a small bias voltage to the amplifier stage. holding it muted. When you plug in a jack lead it disconnests the bias using the same contact you'd use to disconnect a loudspeaker on a headphone jack. The bias voltage slowly leaks away over about 250ms allowing the DC conditions in the preamp to settle, driving it out of cutoff and passing audio normally (well, except for the intentional distortion).
Ah, but that's not important. Mankind is producing eleventy billion trillion tonnes of carbon dioxide just simply by existing, and it gets into the atmosphere and by (handwave handwave) mechanisms too complicated to explain to someone so obviously stupid as to believe that climate change is happening (handwave handwave) it only absorbs heat from the earth and only releases it back to the earth and then the ice melts and the polar bears all die.
Either that or the pro-AGW believers are utterly divorced from reality.
Sure, some people don't like diesels due to the noise they make. They are typically quieter when cruising as the RPM is often about 1000RPM lower than a petrol engine.
I can't understand why people keep bringing this up. I had the profound misfortune to drive a petrol hire car recently (Ford Focus) and it was the most dismal motoring experience I've had in a long time. The blame for that can be laid squarely on the gutless, noisy, smelly petrol engine. Going back to my van (Mercedes Vito, 2.2 litre diesel) was like swapping a half-dead carthorse for a thoroughbred on speed.
There's zero reason for a commuter car to have a 0-60 time 8 seconds,
Unless you want to be able to merge on to the highway.
I can safely say that in about 20 years of driving I have never needed to accelerate from a standstill to merge into 60mph traffic. If you find yourself doing that so often that you need to buy a racing car just to get to work, you may have a problem with your traffic engineering.
Diesel engines will run on anything that will spontaneously combust at the temperatures achieved in the cylinder. Unlike a petrol engine, there's no throttle because air-fuel ratio isn't important - you want as much air getting shoved in as you can, which is why turbocharging is so much more effective on a diesel. One (fairly rare) failure mode of diesels, usually caused by neglect and poor maintenance, is "runaway" where if a fault develops it starts drawing up engine oil through failed oil seals or the crankcase breather, and running on that. Even with the fuel turned off, it will continue to run on the oil vapour and droplets. Of course, people then panic and run away and the engine over-revs until it fails totally, which is stupid. The correct course of action is to put it into top gear, plant your foot on the brake and gently let the clutch up until it stalls.
Its one of their famous farming subsidies which keep farmers happy.
No, road diesel isn't taxed at a lower rate. You can get red diesel which has identical properties but has a red dye added (looks like snakebite and blackcurrant, hence the name "Diesel" for that drink) but which is taxed at a lower rate. You can't use red diesel in road vehicles.
Certainly on the font sample presented on the BBC site, the Arial font version was a lot *harder* to read because it was all crushed up without enough leading.
We wouldn't need hundreds of pounds worth of batteries or hybrid drivetrains and we'd still get a practical 300+ mile range out of these cars.
We could just make the cars lighter and fit a small diesel engine to them. I'll take 70mpg and a 500 mile tank range over an electric car that will get me half-way to where I want to go.
Electric cars are not the future. Especially not in California, where they don't even have enough electric power to keep the lights on all the time.
During and after the second world war, many car manufacturers shipped "CKD" (Completely Knocked Down) cars to foreign countries. These arrived as crates of bits that could be quickly and easily assembled by local labour in simple workshops. It doesn't take a lot to put a Morris Minor together, and they were considerably harder to assemble than a modern car as anyone who has ever done a body-off restoration will tell you.
Van Hool are a coachbuilder. They don't make the chassis. The Van Hool-bodied Volvo B10Ms were excellent, though. I wonder where M8 SKY and 12 EWO are now?
Yeah it sucks. And it's slow (CPU intensive). And I can't get back to the classic (plain text) index even though I've un-checked and checked it multiple times.

That does seem a bit odd. The reason I wouldn't inflict the MMR jab on my children is far simpler - the numbers don't add up. I don't know anyone who died of measles. Everyone I know has had measles, so presumably *someone* I knew would have actually died, if the statistics pushed by doctors and pharmaceutical companies are correct. Let's be clear that I'm talking about people I went to school with, since the statistics are all about how many children would die if they weren't given the MMR vaccine. I know a couple of people who died in car accidents, two who committed suicide, one who died of cancer and one who died of meningitis - but no measles. I'm old enough that BCG (tuberculosis) and polio vaccines were routine (and rubella, for girls - not so nasty if boys get it but it's particularly horrible for pregnant women).
Walking in the sun for a few minutes send more radiation into your body than spending 8 hours at a computer.
I bet at least some of the parents who complain about wifi making their children ill let them use sunbeds. The risk of contracting melanoma from exposure to UV in short, powerful bursts - like using sunbeds - is well documented.

Please help by finding copies of their graphics, stylesheets etc. on the 'net and posting them on your own site. It *is* public domain, after all.
You would be reduced to a meaty pulp mixed with shards of plastic and spread over the roadway.

Watch this episode of The Secret Life of Machines. If you're in a hurry, skip to around 2:40 for a demonstration of the difference between gunpowder and petrol.
Then go and download all three series from the Internet. It's okay to do that, because Tim Hunkin told you to do that.

"anti-Vaxxers", because obviously believing that the Big Pharma companies are always acting in your best interests shows true critical thinking.
