London Low Emission Zone - Feasiblility Study

He threatens Big Business with Carbon-Emission Trading and wants to raise CAFE Standards for the struggling Automakers, yet he flies all the way back to Chicago from DC just so that he can make a grand whistle-stop ceremonial entrance into DC for his inauguration? What about his carbon-footprint?

Most rich environmentalist are ……its kinda like do what i say not as i do ……

Al Gore seems to be the biggest hypocrite in this area

i have 79 el camino, replaced engine with 305 from caprice(80-8???) its been running for 3 yrs, but i cant pass emissions, to rich, the carberator that is on it now is computerized, my cars not, the mechanic jimmied it to run with no sensors connected. cant fix that i need to replace, looking into edelbrock(rebuilt) for about 189.00 from craigs, but what carb do i order that will fit, carb sits on an edelbrock intake manifold. pls help me i’ve been riding on 3 day permits(oops i messed up on a # of the vin) for 3 yrs.

The non computer ones go for around 200.00 rebuilt (Quadrajets) If you go edelbrock make sure it fits your style manifold and is smog legal of course.I’ve seen new one go for over 200.00 so you just may want to get a junkyard one and rebuild it. there is a juinkyard service here as well as parts stores to look up items http://painintheexhaust.blogspot.com

I have heard that the all-new Honda Civic has some amazing technology. The unburnt fuel of the previous stroke is pushed back into the combustion chamber again by the piston to mix with new fuel to give better fuel consumption and low emission. Isn’t this too good to be true? This results in better fuel consumption where the 1800cc engine gives fuel consumption of that of 1500’s according to automobile journalists.. What are the other technological gismos in this that its other competitors like, the Sentra, Corolla, don’t have? Anyone owns one? Are you satisfied with yours?

Interesting question, because the user reviews vary so widely in the answer to this. I like the reviews by users on Yaho! Autos (see link below).

My personal experience (I have an EX coupe) is that I get better mileage than the EPA rating. I get 34-35 in town and 40-41 on the highway on a consistent basis. To be fair, I am a very gentle (though not necessarily slow) driver. I would guess that hard accelleration, air conditioning overuse in town, and leaving your foot on the gas while going downhill (instead of letting the car coast for the freebie), would take a toll on this car’s little engine very quickly. I bought this car as a 5-speed, and I’m pretty good at making use of a manual transmission as a mileage tool.

Through smart driving, being fortunate enough to have a 10 mile round trip to work, and planning my trips for maximum use, this car lets me get gas once a month with only a 12 gallon tank.

When I got this car early last Fall, it had just become available, and my friends (who were accustomed to seeing me in "prestige" cars) assumed it was an Acura because of its sleek styling (though the sedan looks very "gals in the secretarial pool") and gizmos (one touch up/down windows and sunroof, iPod jack built in, MP3 player, XM radio, steering wheel audio controls, stylish wheels, and the wonderful two-tiered instrument panel, etc.). I skipped out on the sattelite navigation system and the foglights, and got the thing for $18000, which is the least I have ever paid for a new car.

Funny story about the cool-quotient of this car…Last month I valet parked at a hotel in Chicago, and to my surprise and delight it was my economical Honda parked next to a Ferrari, a Bentley, and a BMW 7 series at the valet stand that drew a crowd of foreign onlookers posing for pictures next to it. I parked next to an Audi TT at a coffee place, and the TT owner stopped to tell me what a cool looking car I had. I’m still chuckling all the way to the bank with every payment and fill-up.

Other innovations on this car are about safety, which was important to me. I won’t go into the tech details (though the second link below will take you to Honda’s website if you’re curious), but this car won 5-star front and side impact ratings from NSTSA, and best pick from the Insurance Institute for Highway Safety for a reason.

For me, I wouldn’t have even considered the Scion (which looks distinctly inexpensive), the Corolla (just plain ugly), or the Sentra (looks like a 90’s car, still, and rotten crash test results).

If you’re looking for a 4-door, the Mazda 3 is an amazing value in a nice loking package. While you’ll give up a bit of mileage for it, it pays off with extra power and unbelievable roominess for a car in this class. It’s what I would have bought if I had a non-coupe lifestlye.

in the process of installing short ram intake in my car. its a Weapon- R, secret weapon- short ram intake. the car is a Honda Accord 2005 v6.

Absolutely.

They’re even CARB exempt for one specific reason. The CARB people did thorough testing and it was proven that intake systems have no adverse effect on emissions, as they do practically nothing to alter the performance/operation of an engine.

In other words, they do nothing. Nothing good. Nothing bad.

Hope you’re not buying it for "performance"

How do hydrogen based cars give off less greenhouse emissions? Technically, isn’t water vapor considered to be a large contributor to the greenhouse effect, even more than say CO2? Not to mention, won’t the energy from a hydrogen car have to come from a most likely oil based or coal based source, thus losing efficiency between the energy transfer and thus making these cars even less efficient from a global perspective? I do realize that the hydrogen cars may be more efficient from a combustion sense, which may raise the global energy efficiency, but by giving off water vapor, wouldn’t that just make global warming (I’m assuming it actually happens considering that most scientists believe it does) worse?

It’s whether or not there’s a net increase in the atmosphere. The idea behind a hydrogen economy is that the hydrogen is extracted from water from the environment, once recombined with oxygen it just becomes water in the environment again, no net increase. With fossil fuels, the hydrocarbons represent carbon and hydrogen that has been sequestered from our environment for millions of years, using the fossil fuel combines it with oxygen in our environment to form CO2 and H2O resulting in a net increase of CO2 and H2O in our environment as well as a net decrease in O2.

Of course, gasoline and diesel don’t have to be refined from fossil reserves, they could be synthesized from CO2 and H2O in our environment hence achieving the same zero net increase of a hydrogen economy, indeed that was the conclusion of Sandia Labs research into more efficient ways of producing hydrogen from H2O, the same methods used to extract H2 from H2O can be used to extract CO from CO2 and a mixture of H2 and CO can synthesize gasoline/diesel via the Fischer Tropsch synthesis.

Synthetic liquid hydrocarbons would have the advantage over hydrogen of not only being more compact, more stable and easier to contain but the advantage of working with the nearly one billion existing vehicles and with the existing infrastructure thereby avoiding the carbon footprint of new vehicle manufacture and of constructing a distribution infrastructure.

Synthetic fuels also have the potential for being carbon negative if biofuel to liquid processes like gasification/pyrolysis are used in conjunction with biochar carbon sequestration.

Being carbon negative is something a hydrogen economy would not achieve but ironically existing gas guzzlers could if we just changed how we make gasoline.

It is ironic that what most would consider the environmentally friendly option, that of hydrogen fuel cell cars, is actually not the most environmentally friendly option at all.

well what is so bad about CO2 emissions? it stands for carbon dioxide right? is that the stuff humans exhale???????????? aswer please!!!!

Good question.

I work for an energy company and hopefully can help. Saving energy helps you and the environment. When you save energy, you save money on your power bill. It also helps to reduce the amount of energy that power companies need to produce. Since 50% of the US energy comes from burning coal and 20% from natural gas, it helps reduce the amount of carbon that these plants emit. Our company is a huge advacate for saving energy and encourage our customers to do so.

well what is so bad about CO2 emissions? Well, in small amounts? Nothing at all. We do exhel carbon dioxcide, but in small amounts. World wide we emit roughly 28,431,741,000 metric tons of CO2 every year from energy sources. Much more than the breathing of the human population. In large quantities, it can be very harmful to wildlife, air quality, etc. The amount of this affect is always debated, but the fact is that too much CO2 is definately not a good thing.

Now the total emissions, in weight (metric tons per year) are very similar. If we take all of the NOx emissions to be NO2, and the total mass of both to be 150 metric tons per year, how does the SO2 and NOx production compare on a per mole basis?

relative number of moles-
NO2: molar mass = 46
SO2: molar mass = 64
NO2 has 1.39X the moles of SO2 (64/36)

I am looking for similar stories regarding high repair bills in North Carolina to pass the Emissions test. If you have one please respond, I would like to send them to my local representative. Maybe he can do something to help stop this madness.

It’s more per county than per state….. try going elswhere, never know, it may work. My county doesn’t have an emissions requirement…

I know in cali you can only lease new diesel cars.

yep. I am in NV, and a dealer - we sell them all the time.

What are the things you do that contributes to CO2 emission & what can you do about it to save our Earth?

Basicly, use less energy, unless it comes from a renewable resource, and plant more vegetation. Plants take out CO2 from the atmosphere.
Most fuel sources are from fossil fuels and nearly all put in more CO2 emission in the atmosphere. Carpool, if possible and turn of all electric appliances when not in use
