How much fuel does an idling engine use? After how long will an idling engine use more fuel than simply shutting the engine off, and then restarting it? It turns out, most Americans have no idea, as the journal of Energy Policy interviewed 1,300 US drivers, and the average time guessed was 3.6 minutes! 3.6 minutes worth of engine idling fuel required to simply start up an engine!
Well, let's put the myths to rest and look at actual data, published in the journal of SAE. Researchers took two identical engines and measured their idle fuel consumption, how much fuel they required to start up, and then spent time conducting real world driving tests to see if engine start-stop systems actually save fuel. Check out the video to see the results!

I've tried a similar experiment with my motorbike a few years ago. I found that I could save about 10% fuel by stopping the motor at red lights on my usual commute. But I'm not just worried about wearing out the starter motor, I also think that I'd drain the battery pretty quickly without longer stretches to recharge it.

@mitchelbrown793 Год назад

I'll pick safety everytime, whether on my bike or in my car. I want my engine on so that if I do not like the speed at which the car behind me is coming in, I have the option to go, to move, to drive forward, to get out of the way. Regardless of the wear on the starter or the potential battery drain. My safety comes first. But I also drive very defensively. I often get funny looks at intersections because I will leave whole car lengths in front of me so that I have space cushions. I've always operated under the assumption that 30 seconds of idling would use about the same amount of fuel as stop starting the engine, but I don't care if I'm waiting for a 2 minute light. Safety first.

In India, red lights also have timer display, which shows time left in seconds for the light to turn green, so that a driver can decide if the red light is long enough to turn off the engine.

@johneverett3947 Год назад

It would be interesting to see how quickly the oil pressure drops when an engine is shut off. And if the fluctuation in oil pressure due to constant stop starts effects engine wear? I have always wondered why auto manufacturers never considered an electric oil pump to pressurize the system before starting an engine to reduce wear. Also if the alternator and starter are one unit in a stop/ start system does that double the possibility for failure in the system and also increase the expense?

@nicholaswins 11 месяцев назад

Probably because electric oil pumps would be much more prone to failure compared to those driven by the engine, which is a reason why BMW has so many problems with their water pumps failing over the years because they chose to make them electric.

Very fast actually, within 1-2 seconds pressure drops about 90%... at least if your car has 100'000miles... new engines i dont know, but it will still drain fast, because oil isnt compressable, so already a tiny leak will make pressure drop very fast...

It also depends on your battery power use to start the engine again. I've read that it takes about thirty seconds running your engine to recharge your battery after starting the engine, which I confirmed with my auto technician. So the first time or even second or third isn't so bad as long as your not doing it so much to drain your battery without allowing it to charge.

@irrichman Год назад

A built-in start stop system will take into account battery charge. So low charge and the engine keeps running. Cold engine is also taken into account, so when the oil is flowing nicely the system engages. AND also after maybe 90 seconds or 2 minutes, the enige will restart (i guess to keep oil flowing and prevent the engine to cool off too much). My Clio 2015's system works when stationary and when you shift out of gear ('neutral' but on a manual gearbox), so the automatic restarting can't be a danger. When you press the clutch to shift into gear, the engine restarts automatically, so you can't be in gear when the stop phase times out. So you have pretty much full control of when it works, or until the stop phase times out.

@stephenhendricks103 5 лет назад

It's videos like this that are the reason I subscribe to this channel. Like most self-styled "enthusiasts" I didn't like the start/stop system on my new GTI and thought mistakenly that any fuel efficiency advantages were probably cancelled by the fuel needed to restart the engine. But as an old professor of mine once said, "The thing about data is that it sure does cut the bulls**t." In the meantime, I discovered another benefit of the system. Each day I make a trip to the local Starbucks and wait in line in an enclosed "tunnel" outside the store. Typically, my engine shuts down when I pull into the tunnel and when I reach the window. The baristas at the window have thanked me on multiple occasions for shutting off my engine, noting that they have to breathe exhaust fumes all day long. It's not a big thing but it's worth noting that in addition to reducing fuel consumption to some degree, start/stop technology makes the air a bit more breathable for everyone, some more than others.

@stephenhendricks103 5 лет назад

Khargan: Since you would "never own a vehicle with a start/stop system" I suspect you've never even driven one. I have. Several, in fact, including the two I own. Besides, the notion that less than a half second hesitation in your car's movement would avoid or even mitigate the impact of a vehicle bearing down on you at speed is ridiculous, especially since you would not be able to judge whether the vehicle was approaching too quickly until it was nearly on you. Furthermore, even if you make such a judgement accurately, you're probably better off bracing for a rear end collision than plowing into a vehicle in front of you or running a red light where cross traffic could well result in a far worse collision. Finally, do you really think a manufacturer would install a dangerously sluggish start/stop system in a vehicle sold to the public? If you can document any such system, feel free to cite it. I thought not. Rear end collisions are, indeed, a problem. But they nearly always result from vehicles following too closely, a situation that has nothing to do with a start/stop system. And thankfully, such collisions have been reduced significantly since vehicles were required to add a third high mounted brake light.

@stephenhendricks103 5 лет назад

Your response would be more effective if you included any facts. You're correct that you didn't say "dangerously sluggish." What you did say was that a start/stop system would prevent you from avoiding a rear end collision. If you meant something other than "dangerously sluggish" feel free to clarify.

Counterintuitively, You're actually potentially right. An engine is usually most efficient at peak torque, which is pretty much peak power. So it takes less fuel to get from 0-60mph if you keep the engine at peak torque (assuming no wheel spin or clutch slip) than slowly accelerating. BUT assuming your journeys are the same distance, you spend longer at that higher speed, and for a non zero length cruise time, you use more fuel than if you had accelerated slowly, because you spend longer at a higher speed, and wind resistance gets higher with speed. BUT it turns out there is a most efficient cruise speed, and it's something like 45mph. Any slower or faster uses more fuel. So this only applies if the top speed is over 45mph...

This is a weird premise in general, I’ve never stopped to think if it takes gas or not to start an engine, I’ve never thought about stopping it. Why would I? It’s worth the money in gas to have the A/C and radio on at a stop light or if your just waiting for somone at a pick up or just chilling in your car for an hour. How much gas I’m using is never something that crosses my mind until I’m on the 1.5 hour interstate drive twice a week.

My favorite is when they park at night with the xenon headlights on, idling, and texting for half an hour while I'm trying to enjoy some darkness.

@tamalpias Год назад

I work in service at a dealership, the alternator and starter on an idle stop start car runs about 40% more expensive to replace, the arm battery costs twice as much. Even engineering the starter and alternator to be more robust they still fail at a faster rate than cars not equipped with this function. So bottom line you waste less fuel but more money for repairs.

@busixnesse7384 3 года назад

Engineers think about adding a longer lasting starter, while auto companies need parts to break to make money. Somewhere in the middle you find the actual starter life.

I knew about that 7 sec rule, that's what was written in my BMW manual (who reads it?). So every time I see red light, I check counter and if it's less than 10 sec, I keep engine running... however, auto start/stop feature kills car battery way waster :) So I hardly believe I save any money with this feature :)

@erinmckeand6506 Год назад

This is a great idea in theory, but my mother-in-law's, Ford Fusion turns off at horrible times. I was doing a 3 point turn and it decided to stop. Because the engine was no longer on it was essentially in neutral (It's an Automatic (gross, I know)) and my gentle reverse turned into almost rolling back into the ditch. Some car do it way better though, but definitely not Ford.

@@bf3and4highlights83 The battery is being recharged when the engine is on, you know? Maybe turning the engine on and off multiple times in a few minutes doesn't really save money, but doing it when waiting at an occasional traffic light will very likely be benificial. Also why do you assume that starting an engine wears out any parts (apart from maybe battery, which isn't expensive)?

It would be nice to see a follow-up study designed to measure engine wear in idle vs start-stop conditions.

Not much, because the engines are still pretty hot when they restart, so the usual cold start engine wear isn't really happening.

As your turbo charger can be superhot its not good idea to shut engine right when you stop

@lexisnep525 Год назад

@@michalhudek In a turbocharged vehicle equipped with idle stop, manufacturers either fit an auxiliary oil pump to keep cooling the turbo, or they use a temperature sensor to prevent idle stop while the turbo is too hot. Honda is shipping their 1.5T in almost every car in their lineup now, as well as the 2.0T in Acura vehicles, and all are equipped with idle stop. Engineers know what they're doing.
