E100, propane, CNG. they all put out very little emissions and they are better for the engine. less mileage and power though unless you increase engine compression or timing

Europe is all over small turbodiesels, great mpg but they won't pass emissions over here.
They have to much sulphur in thier diesel

This is true, although I remember reading somewhere that the new Ecoboost powerplants offer a 15% reduction in greenhouse gas emissions (I believe it was in reference to the 4 cylinder version)

What is a green house gas?
Oxegen is a green house gas, so is nitrogen. Without those two in our atmosphere we wouldn't need cars.
In no way do I mean to disrespect anyone but, PLEASE do not get caught up in the global warming, green house gas propoganda. It is a well manufactured selling point for ecologists.
I have my degree in Geology. I wrote about a ten page disertation about the history of the earths climate. The warming and cooling in the past has far exceeded what we are expirencing now. We have had rapid warming to the point that there was no snow to be found on this earth, and there were no cars to be found on this earth. The same goes for cooling. We are part of a cycle that has been around for billions of years. Trying to under stand the climate in human history is akin to understandind a person from a DNA sample. You can tell alittle about the person, but not the nuances.
CRAP Sorry! I will get off my soapbox now.

We do need to clean things up. My personal favorite is Hydrogen. It is not that much of a paradyme shift from gas. We will just need stainless steel exhausts

meh, I take no disrespect, but I'm not really buying into anything. I've read the evidence for the green house gas contribution to the global warming effect, so it's not exactly propaganda or some sort of conspiracy theory.


But I digress. I agree with you, we do need to clean things up. Hydrogen would be a good choice for the future, but with some of the newer engine technologies coming up we can actually squeeze a bit more efficiency/lower emissions out of the motors. Which I suppose would be more of a immediate solution.

This was on Nova tonight. It talks about the same things we have talked about here.

Holy shit dude. What kind of degree do you have in geology that makes you an expert in atmospheric compositions? And 'about a 10 page dissertation' my ass. I have yet to meet a scholar who doesn't know how many pages are in his dissertation. Plus, a dissertation implies a Master's Degree, at the least, and I find it hard to believe someone with a Masters or Ph.D can't spell paradigm or understand. Last, Dissertations are not 'about 10 pages'. I've seen dissertations with 10 pages of references alone. 10 pages is a decent paper for a 2nd-year course, not

Neither Oxygen or Nitrogen are greenhouse gases. To be a greenhouse gas, it must allow light waves to pass through, while reflecting heat waves. A property very prevalent in CO2 and Methane, among others.
Never in the documented history of the earth was Antarctica ice-free, so your "no snow" idea is total crap.

The fact is current CO2 rates are nearly 50% higher than EVER BEFORE, as proven by studying ice cores in the antarctic ice sheet.
Permafrost is melting all over Northern Canada and Russia, causing previously frozen organic matter to break down and form methane - which is 23 times more potent than CO2.

Global Warming is not a hoax. It is a proven scientific fact, and its people like you that allow Governments to curb their emissions standards and shit because some dumbass "scientist" who has a completely unrelated degree is telling them its bullshit. Do you expect a Physicist to come up with your Foreign Policy? Hell No!! So why let a Geologist - someone who studies ROCKS - tell you about the atmosphere?

My original reason for posting this was not cause an arguement. I posted this to have a discussion and to show that what we are doing to save the enviroment is actually destroying it. All was cordigal until you posted your condescension, beratement, and diatribe. I had just typed a long reply to your post in which I talked about all you points. It did not go through. I am glad for this because I fell into your angry little world. If this is how you reply to all posts, please reframe from replying to mine. Hope you have a better day tomarrow.

While I agree and know that the global warming is part of normal cycles, I also noticed his guys total lack of education as evident by his gross misspelling of simple words. lol

Global Warming is not a hoax.

It could be. Plenty of incidents where so-called scientists have falsified their research. There is an incentive to "prove" global warming because that's where the money is.

It is a proven scientific fact

In the past the earth has gotten warmer and the earth has gotten colder, long before the invention of the SUV and burning of fossil fuels.

The earth MAY be getting warmer. Whether or not we are causing it is questionable. Just because B follows A does not mean that A caused B.

There were periods where Earth has gotten cooler and warmer due to certain geological events, this is true. However, the warming trends have been shown to be attributed to green house gas emissions. This you can't deny. Also, it should be stated that the green house effect wasn't even well studied until scientist started looking at Venus and it's run-away green house trend

 

[JohnnyO]

This you can't deny.

Yes I can. They find global warming because they are paid to find global warming. There's a whole lot of fraud going on.* There is little in the way of research grants to NOT find it. Besides which, even if it was true, why is it a bad thing? Longer growing seasons, lower utility bills, less severe winters (which ain't happening here btw), women wear less clothing. I live in PA so I'm all in favor of global warming.

* The intercepted emails from the University Of East Anglia, the leaders in global warming research, pretty much proved that they're full of shit and they know it.

Comparing window stickers on the new F-150's says it best. Ecoboost 3.5L makes the same power and has the same tow rating as the big bad 6.2L. One is in the low 20's and one is in the low teens.

E100, propane, CNG. they all put out very little emissions and they are better for the engine. less mileage and power though unless you increase engine compression or timing

Non-issue if you are designing engines for new cars.

Personally propane tractors scare the heck out of me because you can't just throw floor dry on a fuel leak. We work on fuel related problems outside on the most humid day possible, which is kind of unhandy. It is cool to pop the head off and see a spotless engine though.

you just shut the tank valve. easier to clea up a fuel leak cause there is no mess!

propane forklifts can be run indoors because of the extremely low emissions, we had one that went 7 years before an oil change just for the sake of changing it haha

I'm with JonnyO. Very sound reasoning here.

Too many sensationalists who enjoy fear-mongering and pushing this global warming crap. Mostly tree-huggers who have good intentions, but just dont have scientific facts. They "think" stuff is bad without empirical evidence and then push people to agree, then push for social reforms, government intervention, which means bigger government, then socialism, etc etc. See, its all evil

And yes, I prefer to remove cats on performance vehicles, sorry hippies

 

[Ranger44]

I'm sorry to say, but catalytic converters are band-aids. All they ever were.

If we really want to reduce emissions we need to reduce fuel consumption and wasted power/fuel.

What does this mean? More emissions equipment and management systems on that engine. In order to maximize the combustion process in the cylinder is direct injection of fuel, and an oxygen sensor right off the chmaber for each cylinder. This way each cylinder is tuned and monitored by itself.

The EGR was designed to reduce NoX. NoX is produced because of the 2,000 degrees F that a combustion chamber sees. Therefore exhaust is recirculated to the cylinder to reduce temperatures.....therefore reducing NoX production. SOOO those lean burn engines run HOT....thus producing more NOX.

Hybrids aren't that bad of a concept. They just need to be refined and tuned more. Keep in mind an electric motor makes peak torque right off the line.

Past this.....I'm not sure what's in the works or will help with emissions.

The combustion engine isn't going anywhere for a while. We can improve on it......but it isn't ready to be phased out just yet, battery and electric motor tech isn't near what it needs to be to do so.
