Scientists Claim Major Leap in Engine Design
An anonymous reader writes "Purdue researchers say they have made a major advance in the design of the internal combustion engine, one that could seriously boost fuel efficiency and cut emissions. A key portion involves building intake and exhaust valves that are no longer driven by mechanisms connected to the pistons, a departure from the way car engines have worked since they were commercialized more than a century ago. 'The concept, known as variable valve actuation, would enable significant improvements in conventional gasoline and diesel engines used in cars and trucks and for applications such as generators, he said. The technique also enables the introduction of an advanced method called homogeneous charge compression ignition, or HCCI, which would allow the United States to drastically reduce its dependence on foreign oil and the production of harmful exhaust emissions. The homogeneous charge compression ignition technique would make it possible to improve the efficiency of gasoline engines by 15 percent to 20 percent, making them as efficient as diesel engines while nearly eliminating smog-generating nitrogen oxides, Shaver said.'"
Except that your extra horsepower is constantly being used to drag around your huge SUV that you somehow believe is compensating for your small penis.
You selected the wrong entry from the Standard List of Villains. The correct comment would have been:
"What's the chance the EVIL OIL COMPANIES will buy this out and kill it?"
when they pry them from my cold, dead fingers!
from the blurb:
...which would allow the United States to drastically reduce its dependence on foreign oil...
Editor doesn't know much 'Murkins, does he? This will be used to create higher-horsepower, heavier cars, not more efficient ones. Coming soon: The Hummer Canyonero-Magnum!
Remain calm! All is well!
Based on his or her wording I'd say he or she was mainly fascinated with his penis.
I am the inventor of the hilarious refrigerator alarm.
Increasing horsepower and torque is very useful... makes passing a slowpoke driving a Prissius quicker.
Most people don't even think inside the box.
And who has the smallest penis? Women!
Then there are those of us that drive SUVs because our penis wont fit in a compact.
Yay the rotary! Considering there's only one car manufacturer putting development in the the wankel engine the RX8 is an amazing achievement. Imagine if it had the same R&D poured into it as the piston engine!
Pistons are fundamentally flawed, they go up and stop then down and stop... what's up with that?
Anyway a 15% improvement in efficiency will only result in 15% bigger SUV's.... I know how you Americans think!
Socialism: a lie told by totalitarians and believed by fools.
Oh wow, another slashdotter with little to no knowledge of female anatomy. Go outside.
Actually, I need the horsepower of a large car to drag along my jaw-droppingly huge penis. That, or a powerful motorcycle with a sidecar.

Scientists have finally created a radical new type of bomb for use by countries
that want to "go green". The bomb can flatten entire cities while generating
only one third of the radiation of conventional warheads.
Of course, a slightly more efficient gas-burning SUV is still a gas-burning SUV,
and isn't going to solve anything. We need to stop using SUVs.
So can I have your Hummer now please? I want to learn the hard way :)
I'm only obsessed with my own penis. Excepting of course penises girls keep in their nightstands. And that excepting only the hot ones.
Someone hates these cans.
Women? Minorities? The elderly?
Then either you're a) one of the top bodybuilders on the planet, b) mistaken, c) have more fat than you think, or d) a liar.
You mean all those ads, the ones that tell us that women will flock to us, our boring daily commute will turn into an exciting safari, and we'll suddenly mysteriously have copious free time if only we would just buy product X for no upfront payment, are lying?
I find THAT hard to believe!
Rampant carbon sequestration destroyed the Dinosaurs' tropical paradise. I'm here to help repair the damage.
Well, unless you can pull that trailer with your penis, you are compensating.
No. I'm barrel-chested.
Does that mean you can survive the ride down Niagara Falls?
They're unsafe, slow, can't handle, can't stop...
I'm confused. Are we talking about cars, or Ted Kennedy?
What?
Of course, better efficiency just means more people before we strip the planet of resources.
When are you killing yourself?
Writers imply. Readers infer.
It endangers me more when some lady talking on her mobile phone in an SUV does it, than when same lady driving a car that weighs as much as mine does it... Standard psychics apply. Not sure how psychics apply unless you are using your powers to see into her future and avoid the accident she will cause.
