Do I have to warm up the engine?

Discussions about how much the engine warms upcar, and whether to warm it at all, are not only between novice motorists. There are many opinions on this issue. In disputes about whether to warm up the engine, opponents give a lot of arguments. Among them, references to premature wear of the engine, and the need to achieve the optimum temperature regime, and the possibility of fuel economy, and even the need to comply with environmental safety requirements. To understand this issue objectively, it is worthwhile to consider the main arguments for and against, after which to work out the optimal algorithm of actions.

Arguments for

Supporters of slow engine warming, up tothe beginning of the movement, do not distinguish between whether you need to warm up the injector engine or the carburetor engine. In their opinion, when the engine is not heated, especially with a high load, the wear of parts is sharply accelerated. This is not only due to the lack of lubrication mechanisms. In the cold motor between the parts there is a temporary gap mismatch. When heated to operating temperature, the gap assumes the set values, and the parts begin to interact correctly.

When the engine is slowly warmed up in its details,there are dangerous temperature stresses, the result of which, there may be a serious breakdown. For example, warping the cylinder head or jamming the piston.

Solving the question, to what temperature to warm upengine, it is worth considering that in the cycle of driving, when the engine does not have time to fully warm up, it forms condensate, which then interacts with the products of combustion of gasoline or diesel fuel, forming an acid that corrodes the motor from the inside. Therefore, it is worthwhile to let the motor run until it warms up to operating temperature.

Arguments against

Supporters of rapid engine warming leadtheir arguments. Giving advice on how much to warm up the engine, they note that when driving, the motor warms up more quickly and therefore reduces the operating time in an unfavorable mode. After working at idle speed, the engine heats up rather slowly.

Slow warm-up leads to a significant over-consumption of fuel, since all this time the car costs, and does not go to the destination.

The question of whether to warm up the dieselthe engine is not discussed at all, since, according to experts, modern diesel is normally warmed up at idle speed, to operating temperature, it is generally impossible.

Putting in the forefront, environmental priorities, foreign manufacturers note significant damage to the environment, which causes the engine running at idle.

Optimal algorithm

At the heart of the optimal solution to how to properly warm up the engine is a compromise option. The car is to start with the clutch pedal fully depressed, and then release it very smoothly.

Depending on the air temperature, it is necessary to giverun the engine at idle for 1 to 10 minutes to ensure that the thickened grease is slightly warmed and distributed over the parts. In this case, in the winter time, it is not necessary to turn on the fan of the heater for maximum power, this will slow down the engine's heating.

After warming up the engine to a temperature of 45 ° (and in"advanced" foreign cars can be up to 20 °), you can smoothly start the movement, making sure that engine speed does not exceed two thousand. When the motor warms up to operating temperature, you can continue to move in the usual rhythm.
