Wanna Save the Planet?

January 16, 2009

Here’s how. Its not a big thing but if all of us do it then it will make a big difference.

Its a trick from the book of hypermilers. Hypermiling http://en.wikipedia.org/wiki/Hypermiling is trying to get the best mileage out of your car. They do crazy stuff like turn off their car going down hills, or accelerating very slowly.

But here is an excellent way to save the planet and save yourself a few bucks. It takes advantage of a technical aspect of your car. Its called Fuel Cut Off Overrun. Its used by car companies to get their EPA rating.

Basically it is this. When you car decelerates, in gear and the engine is turning over at over 1,500 RPM, the fuel injectors ARE TURNED OFF!

This prevents raw gas from being dumped into the engine and out the tailpipe.

Here is how you use it. Look ahead, if you think you need to stop, take your foot off the gas. That is it. That is all you have to do. Plan ahead and take your foot off the gas. If you have to use your brakes, use them to come to a complete stop after coasting.

To give you an idea of the impact of this, I did a test. I drove to and fro from work driving how I normally drive. Then I just used this technique and this technique only. I got 100 km more out of my tank. That is 20% more. That is a big deal.

I then went extreme and used all the crazy hypermiling techniques and got an extra 90 km more. That is how powerful this knowledge is.

Please try it, it takes some getting used to but it very quickly becomes habit. My wife started doing it as well and guess what. After a tank or two she too was getting 100 km more.

If we all saved 20% of the gas we used, that would meet our Kyoto targets. Go ahead, save the planet, I dare you.
