Debate about warming or not warming the engine before start, arose simultaneously with the appearance on the car market, where manufacturers directly indicates that you can sit in a cold car, start the engine and go immediately.
On the other hand, several generations of car enthusiasts grew up on the products of the domestic auto industry, just as surely argue that the engine must be warm always.
the Resource engine
Especially hard to have all the parts and mechanisms of the engine in the first minutes after a cold start. Due to the fact that engine parts made of different materials having different coefficient of thermal expansion, some components of the engine is wobbling because of too large gaps between parts, in other arrangements, the opposite, there is increased wear of the rubbing parts due to the low clearance and lack of lubrication.
Now imagine how will "feel" the engine, if you put the car in gear and start driving, driving the car. Load transmitted to the engine while driving through the transmission, will lead to the fact that the engine will wear out. And the issue of major repairs from a very distant perspective quite quickly turns into harsh reality.
From the point of view of arithmetic, the smaller the engine warms up at idle, less fuel is burned without performing useful work. Sort of correct, but in real life goes exactly the opposite.
The fact is that when you start the cold engine in order to prepared from cold air and fuel combustible mixture has ignited, it needs to be pereobogaschenie. In injection engines is engaged in automation, in gasoline – the driver, pulling on the "leak".
As a result, moving on the car with the engine cold, consuming pereobogaschenie mixture and of the revving, the driver will spend the same or more fuel than if he heated the motor up to regular temperature, and then began to move to a car engine which consumes a normal or slightly lean fuel mixture.
The statements of the environmentalists that warmed idling the engine pollutes the atmosphere with toxic emissions, and therefore the waiver of the warm-up preserves the environment, to put it mildly, is not correct.
Yes, running the engine and immediately having just departed on a journey, you get rid of air pollution in a particular yard or at a particular Parking lot. But, riding on the road and actively podgotovila, you are poisoning toxic hydrocarbons space along the path of movement until, until the engine warms up and will not work in normal mode.
How to warm up the engine
Running the motor of your iron horse, do not hurry to include the transfer and go somewhere else. Get out of the car, in the winter time to sweep up from the body of glass and snow, in summer – wipe clean the windshield, check a cursory glance, not lowered the wheels etc. and only a few minutes later, when the arrow of the sensor coolant temperature will surely be in the middle of the scale, idle speed jet the engine will drop to standard, and the gasoline engine will have to work steadily at idle with an open choke carburetor (choke depressed), you can safely and confidently start a movement.
If you're too impatient or time to warm up is almost there, wait for the deflection of the temperature sensor from the zero position at least a few millimeters, which would correspond to the engine temperature about 500 C, and then touch in way.
Smooth roads to you! No nail, no wand!
