not so long ago was seen by an increased fuel consumption www.drive2.ru/l/458224220728475458/
Given the temperature, it is possible poor quality of fuel, increased load, it was decided to investigate the effect of temperature on consumption .
For the analysis took elm327 diagnostic device. 

Thermal study elm327 Connector OBD2 (under the cigarette lighter socket into the interior) and any convenient device on android (ios could not find a suitable app)
Temperature -22 (temperature limit of operation of car with the wind in our opinion), wind 3-5 m / s, the average warming of the machine, only felt, without closing the front, the study 1:00 (30 minutes for each scenario), the same warm-test place (study two scenarios, highway and city)
Going on the road, the wife of the navigator!

On the road everything is simple, higher speed so the higher the temperature, at a speed of between 75 and low speed just will not, because the engine revving from -this small volume. Having blown a huge, at low speed and high speed such as a roller coaster, with a temperature of 90 ° to 80 ° falls in 15 seconds, but is rising rapidly and at higher speed.

Measurement at idle until the temperature reaches 90, but ooooochen slowly when the stove in position 2-3 is held in the area of ​​80-84

So the city as the most basic place operation car.
In the city especially not to twist, frequent upgrades, traffic lights and pedestrians, and given the fact that the stove 1-2 above do not include more and poor visibility (position always in the feet to be warm, but it is easier to machine).
Accordingly, the dependence of a simple stove directly affects the temperature of the engine when standing still idling at the N 850-910, on D 730-800 (apparently elm327 not immediately transmits data or has a visible error).
