Do Cars Burn More Gas After A Cold Start On A Wintery Morning Do Cars Burn More Gas After A Cold Start On A Wintery Morning?

Do cars burn more gas after a cold start on a wintery morning? - do cars burn more gas after a cold start on a wintery morning

After the start in my drive 5, I can see smoke coming from my car in the rearview mirror. The smoke disappears after the engine has reached normal operating temperature. How do you smoke in the exhaust of cars, almost all of the various subdivisions in the morning. But no car on the road was a trail of smoke behind him. Therefore, burning question - no cars more gas after a cold start until the engine is warm enough?

Most cars have a "high" idle "if you are using a cold morning. There is a sensor, the temperature of air sucked into the engine monitor. If the temperature is too cold, make the engine a bit faster (as if a little off the accelerator) until the engine was hot. Thus, the difference will probably have seen the amount of "smoke" (exhaust) before and after the car is overheating due to increased inactivity, and therefore more pressure exhaust - hot air moves to disappear quickly in the direction of the cold air, so that comes from the cold ".

As for the "gap" or "street" difference, which is probably more a question of speed. For the testPLE - if you lit a cigarette (not that I encourage all to smoke) and I went to the window, that would be smoking when driving slower than when driving fast - the same effect.

The smoke is actually a condensation of burning gasoline. Very normal. Strongly decreases are different components of the exhaust system to normal.

Yes use, not cars more fuel in cold weather, especially after the start, but falls near normal when the engine is at normal running time.

Yes, they are much less effective in cold weather ...

Burning a small amount of extra fuel, not much
What we see is), especially water vapor (steam until the engine to operating temperature.
In the "old" before the computer can control the motor was much worse, could not be tears in a closed garage at idle at room temperature for more than a few minutes without his eyes.
Now that produced an effective control for engines, modern engines use a small amount of fuel in the first few minutes, but it is much better than it was.

Personally, I would say that what they are doing.

what you already warmed by a compression engine is cold very quickly. If all ingredients are hot, stop. But the question that the consumption of gas, it burns less fuel to be answered in the cold to help keep warm until the stagnation
