In winter, in Uzbekistan and other cold countries in general, it is customary to warm up before driving. Scientists say this will not only benefit the environment, but also waste fuel and time.
As you walk through neighborhoods and neighborhoods in the morning, you catch a glimpse of cars burning in front of a garage or gate. If the driver has a remote ignition device, the job is easier to move, but most drivers sit in a cold car and wait for it to heat up.
If people do this, it will be easier to drive a car in the cold, believing that it is harmful to drive an iron horse immediately in the cold. The Washington Post rejects this belief, arguing that modern cars do not need to be preheated.
Heating a car is not just a tradition of Uzbeks or Russians. A 2009 survey found that Americans also warm up their cars for five minutes before driving when the temperature drops below zero.
Why is there no need to warm up the engine?
In fact, this is partly true. First, cold engines "eat" an average of 12 percent more fuel. Second, the engine warms up more slowly in the winter.
Preheating old cars with carburetors is an acceptable practice, as if the unit does not heat up to the required temperature, the car may shut down. However, from the 1980s to the 90s, the carburetor was replaced by an injector, in which fuel and air mixing is controlled by special sensors. It is not necessary to heat the injector engine, as the sensor controls the fuel-air mixture and adjusts it to the desired temperature.
Thus, we emphasize that the modern engine does not need to be heated for a long time. According to an automotive expert, a new car does not need to be heated for more than 30 seconds because it heats up better when driving.
Engine heating pollutes the air
When the engine is running, greenhouse gases are released, fuel consumption increases, which not only harms the environment, but also the driver's pocket.
The Canadian Ministry of Natural Resources conducted an experiment to show that there was no need to heat the car. In -18 degrees below zero, the three cars were heated at different times and covered the specified distance.
The fuel consumption of a car heated for five minutes increased by 7-14 per cent, while that of a car heated for ten minutes increased by 12-19 per cent. In addition, the larger the engine, the more fuel it consumes when running alone. In other words, modern cars will save gasoline as they travel, and when they run on salt, they will "eat" fuel and reduce engine efficiency.
As the cost of driving increases, so does the process of air pollution. In 2009, Energy Policy magazine calculated the total amount of pollutants emitted into the air by American drivers during salty operation. Drivers do not turn off the engine during the cold season, not only when the car is warming up, but also when waiting for something or when the car gets stuck. It is estimated that 1,6 percent of all greenhouse gas emissions from the United States come from saline engines. For comparison: this is twice as much as the harmful substances produced by the metallurgical industry.
Drivers will save $ 5,9 billion in fuel worldwide (based on 2008 prices) if drivers reduce unnecessary engine performance. Harmful emissions are reduced by the amount of soda, aluminum and lime industrial wastes.
