Course I'd let them eat it... not sure I want one covered in the stuff coming out of a car... Oh, and I'm from the south. If someone doesn't have a gun on them they have two in the car. Or in the baby stroller... needless to say, there is one hiding SOMEWHERE. |
so wait you guys havent heard that starting the motor consumes a considerable amount fuel? this of course depends on the car.
anyway, it is wrong for you to shut it off. thats like me walking into your house uninvited, and shutting off all the other lights in your house while you are in the kitchen, coincidentally, getting your cup of coffee. |
Just so you know my xB uses 0.1 gph at idle and that comes out to half a penny a minute. shutting it off and starting again bumps it back up to .3gph for several minutes so keeping it running when I want a little A/C or HEAT is not so bad but most V6 engines burn .4-.5 gps so not as efficient and a V8 must be a bit more than that!

Not really the "leave the key on" without running is a bad idea for the Scion since Stability control and ABS brakes and Power Steering all require engine running properly as Toyota does not even recommend bump starting the engine even though I have on several occasions. I generally just let it idle when coasting and believe me the 3 turns stop to stop steering is very hard to turn without power steering even while moving and any emergency maneuver would be impossible witout power steering.

I went looking for this a long time ago and found a picture from a website similar to this : https://www.prewarbuick.com/features/...r_is_a_war_now The idea is, I think a mileage card on an economy car is more patriotic than a yellow ribbon on an SUV.

I like gas ration card in the back window cfg. Did you just print that off the internet?

I loved what the article said : The national maximum “Victory Speed” was 35 miles an hour. 35 MPH means that the car doesn't have to overcome air friction. They knew what they were talking about back then! CarloSW2 |

Let's say the SUV's V-8 idles at 0.7gph and the time spent idling is 5 minutes or 0.05 gallons. How much fuel does it take to start a vehicle... Does anyone have any data on warm startup fuel usage rates, on average? We may have a myth to bust here. BTW, I like the WWII ration stickers -- I bet a lot of old timers around here would get it.

I believe MetroMPG has a graph on his website showing fuel consumption as the engine warmed up. https://www.metrompg.com/posts/warm-up-idling.htm
Here's a clip from my ecu: enrichment multiplier at startup (similar to a carburetors 'choke' function) 1.14 1.20 1.26 1.40 1.60 1.80 2.2 3.00 Corresponding Engine Coolant temp F 186 176 125 95 69 46 19 3 So the colder it is, the more enrichment is used to start the engine. Some enrichment is used even when the engine is fully warm. Luckily the ecu decreases this enrichment very rapidly once the engine is started, but a little enrichment remains for up to two minutes after starting. One technique to defeat it is to bump start and coast engine off for a few seconds until the enrichment timer counts down some. Keep in mind this is just from the ecu in my car, tho I think it may be similar to the way fuel is handled in other fuel injected cars. I remember hearing a long time ago that it's not worth it to shut the engine off if you have to restart it within 15 seconds. It might be an old myth, but the sentiment is there. What's the minimum time an engine should be off in order to save gas when re-starting? Metro MPG, (or anyone) could you perform another consumption test when the engine is started at different temperatures? It would be interesting to see if the high consumption rates you see in the first two minutes of startup are from this 'choke' function, or if it's just extra enrichment needed to run a cold engine. Maybe try starting with a colder and warmer engine temp, and see where the graphs match? This should show the difference in startup enrichment. |
