In many of my videos and articles where I indicate a syllable about the neutral gear, the hill and fuel consumption, my readers or viewers begin to write: — don't put "neutral" on the hill, the flow will be much more than if you would roll in high gear (say fifth or sixth). Some wrote – "fuel consumption is generally negative," what the onboard computer shows almost negative. That is nonsense!!! That is, a car dressed out of thin air or what? Today I decided to do an experiment it will be useful to many skeptics and "professional".
THE CONTENT OF THE ARTICLE:
- What you need to remember about neutral?
- RACE No. 1: Transfer from the hill
- ARRIVAL No. 2: "Neutral" with slides
The experiment on the hill, neutral, and transmission of purely cognitive, I tested it on three machines (two were automatic and one manual transmission).
What you need to remember about neutral?
Once again, the challenge here is measuring the fuel consumption. BUT IN ANY CASE, IT IS NOT NECESSARY TO DO:
Always roll in neutral on the automatic transmission (automatic transmission). Hypothetically it can be done, but then at the end of the slides need to completely stop the vehicle and further include a "D" for DRIVE and go. To put it in GEAR from neutral to gear on the automatic transmission is PROHIBITED! About it wrote here.
Security. Of course, the car in gear is safer, because it has engine braking. Not brake, namely the engine. Thus, on slippery (icy) hill, it will be predictable and safer descent. FOR our older vases, perhaps a braked motor on a slippery road, Ala security system. On modern cars there are many different electronic assistants, starting from ABS, EBD, etc. that here transmission is already possible and not slow down
WELL now begin our experiment.
RACE No. 1: Transfer from the hill
What I did, I have a lovely bunch ELM327 + TORQUE PRO program. In the past, I have set up the readings on the fuel consumption (in milliliters) testimony of mileage for the trip (in metres), that is 1000 and there and there!
We have a hill 1.5 kilometers on it I measured the two marks. The first is the limit sign of 50km/h, the second is to stop. How will the test I accelerated to 60km/h, from one label to another, then I just let go of the gas pedal and roll for the first time at speed, the second at neutral.
So, up to "60", let go of the gas pedal and it went in gear. The car is not gaining speed, despite the fact that the hill was steep. Well, and then he slowly began to stop.
What happened – consumption 0,062 liter, mileage 2,048 km, well let's remember.
Now the second experiment.
ARRIVAL No. 2: "Neutral" with slides
Actually do the same, turning off air conditioners and other equipment (it was disabled the first time). WELL, there you go.
Acceleration to 60 km/h, and a neutral near the bus stop.
The car started to quickly gain speed, and I expect that fuel consumption will be much higher. But NO, no rapid growth was not simple! I'll even say more, the expense was less than "on speed".
In the END – has done more than almost a kilometer, this is taking into account the fact that we have then the ascent begins, if not he would have driven a lot more. Consumption 0,053 liter, mileage: 2,449 miles
And where are those people who said — that closes the throttle, but the fuel is consumed less or not consumed (direct negative)!!! Here's a simple experiment.
In the end, for the neutral slides, the flow rate is about 10% less, and the mileage is approximately 25% more
