Save Gas and the Environment by Not Idling





Introduction: Save Gas and the Environment by Not Idling

Many people don't realize how much gas they spend idling. Idling your car wastes gas and pours pollutants into the environment. Stopping Idling Is very easy and it will help protect our environment and it will put some money back in your wallet.

This is my first instructable and as you can see above I entered it into the united states of efficiency contest. Please vote for me.

Step 1: Know When to Turn Off Your Car

Many people think that stopping and starting your car uses more gas than Idling. This is completely FALSE In fact If you Idle for more than 10 seconds you are wasting gas. Also It puts unnecessary where and tear on the engine. So when should you turn your car off? There are tons of places that you wouldn't think of. Places like a drive up ATM, picking up someone or any other time you are waiting for more then ten seconds. Just turn off your car.

Step 2: What to Do When You Can't Turn Off Your Car.

There are a few places and times when it doesn't make sense to turn you car off. A for exampled a red light. Yes its possible that you may be sitting at a red light for more then ten seconds but because at least 5% of cars have trouble starting and one stalled car can start a huge traffic jam. Another place where you are stopped for uncertain amounts of time is a drive through. You don't know when you will start moving again so turning off your car isn't really a good choice. What can you do to save gas without turning off your engine? Put your car in neutral this not only uses less gas then traditional idling but it also puts less stress on your engine.

Step 3: What to Do in Extreme Weather Conditions.

When it is very cold many cars need ti warm up before they can drive perfectly but the best way to do this is by driving the car. Idling a car isn't a good way to warm up the engine because cars don't idle at as high a temperate as they drive at. In some extreme conditions it may be necessary to warm up a car by before driving but block warmers are a good substitute for idling. If you do need to warm up your car by idling it shouldn't take more than 5-10 minuets. If it is too cold or hot outside to sit in a car without heat or air conditioning and you are doing something like waiting for someone rather then idling so you can use you heat of air conditioning if you can go into a heated or air conditioned building. If that's not possible than you should try to use the cars heat of a/c for five say five minuets then stop for ten then turn it back on.

Step 4: Other Idling Facts

1 If you are idling you are getting ZERO miles per gallon.
2 Idling for one minuet can produce more pollutants than driving for one minuet.
3 Idling for TEN minuets uses the same amount of fuel as driving for FIVE miles.
4 Idling causes all kinds of heath problems from inhaling fumes form the car.
5 Idling also causes unnecessary noise pollution.

So just just turn off your car.

    You stated " In fact If you Idle for more than 10 seconds you are wasting gas. Also It puts unnecessary where and tear on the engine." this is false start up is a lot harder on the engine because you are essentially spinning the engine a couple of times with very little or no oil circulating.

    I'd have to agree with most everyone in this comment section. This article is extremely misleading, as the unnecessary wear forced on the engine will surely counteract the "savings" that you'd make by not idling. More wear = less efficiency. When moving parts scrape against other moving parts, they turn their rotational (or linear) energy into sound and heat. This then takes MORE energy to dissipate. The more worn down the parts are, the more they will scrape, damaging your engine and your mileage.

    The best way by far to save gas and up mileage is to adopt good driving habits. If you think of stepping on the gas as adding energy to the car's movement, and the breaks as taking that energy away, drive so that you have as little need as possible to remove excess energy from the car (i.e. going too fast before a red light/speed bump) and then only put in the energy you need. Cars carry an insane amount of kinetic energy, and a vehicle in motion WILL keep going when the gas pedal is released.

    As for this Instructable, I would urge the author to remove it in case readers begin following this advice.

    Im all for ways to save money and gas but before giving this advice you need to know the down sides to doing these actions. There is a little known area of science called Tribology which is the study of friction, lubrication, and wear. The reason we dont start and stop the engine is because the lubrication layer takes a short period to build up. Running the car at high rpm in cold weather while still warming up causes more wear, starting and stopping causes more wear. I totally agree with traffic jams and when you know the car isnt going to be moving. I think saving a few dollars a year on the fumes you saved are not worth the part replacement that will come with treating your car like this. I do think people who leave the car on because they are lazy do need to change that, but dont beat up your car, the environmental cost of spare parts probably outweighs the gas you save.

    I wrote this Instructable to try to help people. It was dsined to give people some information if they wanted to hear it. Sure before you do it do some research but just know that multiple sources agree with what this Instructable says. Before you clame that there is false infrormaion here check the coments. There are pleanty of sorces listed to read up on.

    continual start stop on an engine uses more petrol then idling and reduces the engine life.
    working as a commercial mechanic i used to see it an awful lot on milk delivery vehicles.

    These statements are Untrue. If you do not leave your car Idol for 1-2 min before driving there wont be enough oil in the top end. Idling does produce less polutants then Driving at 60mph since your forcing more gas into the engine to burn. Go take a Emission test this will prove you wrong. Starting and stopping the engine at every light or every time you have to Idle you will break something 10x faster . Tons of wear on the starter /battery and other components.If you really want to reduce your emissions and raise the Efficiency of your engine use a Smack HHO booster. Up to 50% less emissions and better fuel economy with better fuel burn.

    . If you don't have full lubrication everywhere in the engine within a second or two, then something is wrong. Get thee to a mechanic and get it checked out.
    . The oil you see on the top end is not doing any lubricating.
    > 50% less emissions
    . Which emissions? You've still going to put out the same amount of Carbon. Unless you are claiming a 50% reduction in gasoline usage.

    With inthe 1st 20-30 Seconds of start up is where you get 80% of wear on your engine..bearings/starter/Lifters . Hot oil drains a lot faster off the top end then you think. Its Never wise to start and stop the engine like this guy wants.Running a HHO booster REDUCES ALL emissions Up to 50% It burns the gas more completely Reducing CARBON .This also Cleans the internal components including the Cat converter. Proof is on this site. Wanna argue more argue with the Owner of the site.

    > It burns the gas more completely Reducing CARBON . . No matter how completely (or incompletely) you burn the fuel (or anything else), the amount of Carbon out equals the amount of Carbon in. Unless you are an Alchemist.

    Here Read what i told you. Go to that website and read the emission tests.If you cant understand them they PROVE on a COPY of the test done by a MACHINE a Reduction in Emissions. THIS argument is Over its proven 100x now . Since you have 0 PROOF you have done your own testing then you can not argue the point.

    . I don't place any more credence in their home-brew data collection than you should in mine. At best, that is dubious evidence and most certainly not proof. They may be right, but I need more evidence than one source who is trying to sell me something.
    . What testing do you propose to verify that elements are conserved in chemical reactions? Have all my Chemistry teachers lied to me?
    . If you put X Carbon atoms in, you get exactly X Carbon atoms out.

    Of course your putting X carbon in to your engine but Less of it. Hydrogen Mixed with Gas Burns Hotter reducing X carbon OUT..Well I guess the Scan PROOF of the emission receipts from 4-5 cars is not proof .I guess you get your infor from what TV or a University that's get their money from WHO? Car/ oil company's? Wow bro you better open your eyes before its to late. Think you better Build a Good booster from Smacks Site its all FREE info and plans He does sell his stuff but he shows you exactly how to build them to. BTW here is another site which has all the proof you need Go Argue more with these 2 guys. These 2 guys are the people who brought HHO back from the Grave,

    . But you said: "It burns the gas more completely Reducing CARBON ."
    > Well I guess the Scan PROOF of the emission receipts from 4-5 cars is not proof .
    . Not without some documentation of the procedure(s) used and 3rd-party oversight that the procedures were properly followed.
    > Wow bro you better open your eyes before its to late.
    . Maybe you shouldn't believe everything you read on the Intertubes. Your conspiracy talk sounds like typical woo-woo to me.
    . I'm not arguing, merely pointing out your lack of critical thinking skills.

    Perhaps you didn't hear the man. He said to go to the website. Well I did, and it's all there in black and white. There's a video of a truck, a video of a contraption with a multimeter, and some pictures of cars (particularilly interesting is the photo of all the people standing in front of a car with it's HOOD OPEN, proving that they know cars). That's all the proof I need. Billions upon billions spent by every major auto manufacturer to make a lower emissions car, and this guy builds one in his mobile home. Priceless. This is the same guy that Ford and GM killed for making a carb that ran on water, right?

    I told you go argue with Smack and the Emissions Tests. They prove my up to 50% reduced Emission statement. ALL emissions Dropped By up to 50% Using HHO.

    >> 50% less emissions > Which emissions? You've still going to put out the same amount of Carbon. Unless you are claiming a 50% reduction in gasoline usage. If you have a large enough system to feed 50% of your needed fuel from the oxy/hyd generator... then yeah, it's gonna cut your emmissions close to that. On the other hand, if you have that set-up, you now drive a hybrid fuel vehicle to start with! crank it upto 100%, and you now drive a hydrogen/oxygen powered vehicle, and your only exhaust will be water, plus any oil that leaks into the cylinders(mainly from the EGR system). now is a system with that capacity gonna happen in a Metro? not any time soon. The average systems most people hack together, and sell plans for on the net... you're making only 3-5% of your fuel usage. POSSIBLY netting a 2-3% hydrocarbon based emission reduction?

    Your 100% wrong here is 1 site that will prove you 100% WRONG. Hydrogen HHO+ Gas make a complete burn your carbon is UP TO 50% less. Read the emission tests before and after you will see my Test there.In My car im at 34% INCREASE in millage and 40% reduction in emissions. My van 37% city 50% highway and a 50% decrease in emissions. ALL this is FREE off his Site i suggest to read a little.

    I'll remain skeptical. The site you referred to gives links to federal documents for HYDROGEN supplementation, yet their technology is injecting the hydrogen/oxygen mixed gas. I have done TONS of research on this type of devise(though this is the first time i've seen that particular website). I even have a hydrogen/oxygen welding torch I built using the same principle. Now, if you can get free electricity, say from solar, then this is great. Sadly, you CANNOT achieve over 100% efficiency(and usually not even 95%). This means you have to produce more energy from the gas generator than it takes to run the generator just to break even in power production. Meaning running this set-up off of the cars electrical system will decrease your total fuel mileage. I do see it as being worth a slight decrease, for the increased emissions... though you have to begin with distilled-deionized water, otherwise your "electrolyzer" will end up in your exhaust. In small quantities, I'll grant, but they will be in there, burning, and have to come out the tail pipe. Smack uses Sodium or potassium hydroxides. When considering emissions... this may help YOUR readings, but you've merely displaced the emissions to the chemical manufacturing plant(where hopefully they SHOULD have a slightly better emissions recovery technique than your cars egr system). I HAVE tested 2 car mounted generators of different design. I got a perceived mpg increase with both, but ACTUAL mpgs decreased ~2%(50 mpg average, down to 48-49). When I switched to charging my auxiliary batteries(separate, just for the gas generator), I did notice a very noticeable increase(from 50 to 52-53 average) in millage vs straight hydrocarbon fuel. But, this was because I was merely changing where i got my energy from... wind power, stored as electricity, used to split water vs. Straight internal combustion of hydrocarbons. To Johnnyscolex, no. I've never heard of any embrittlement of cylinders. Not to say it doesn't happen, but the stoichiometric chemical equation of a properly functioning generator should do no harm. With that particular design, the gasses are bubbled through a secondary water container... giving the gasses a place to pick-up or deposit stray electrons as needed. So it becomes a simple auxiliary fuel supplement. Direct propane injection would produce similar results, but without the lowered emissions. In an older cast engine with iron cylinder sleeves, the metallurgy might be off, allowing for a quenching effect that could over harden the metal, without the normal tempering. this COULD lead to a brittle state, and cylinder wall failure. Fortunately, modern engines are designed to handle this without a hiccup. It is LIKELY, some of the emissions gains come from the fact that you are , not only adding stoichiometric fuel (water->hyd/oxy->water), but also, the water vapor formed helps cool the cylinder. It is replicating the water-injection technology that some hot-rodders used to use with their superchargers(well, I'm being told, that modern turbo-charged engines benefit from this too). And, as the water from the combustion reaction turns to steam, it helps clean deposits off the cylinder walls, and SLIGHTLY adds to the expansion factor of the exhaust stroke. The cooler cylinder leads to a cleaner burn, less need for the egr system, more CO2, less CO and HC out the tail pipe. And to anyone in california that bemoans their CO2 emissions test standards, I advise telling your government to STOP BREATHING. Their hot air is producing more CO2 than my car ever will in it's whole lifetime :-)

    having any problems with embrittlement? hydrogen systems like this unless installed and tuned correctly cause the cylinders to become brittle during combustion there arent enough electrons present and they begin pulling them from cylinder walls. which causes the walls to become brittle eventually causing the engine to destroy itself.
