What are the impacts of idling the car for 10 minutes to warm up?

[GenevieveFitz]

The impacts of idling the car for 10 minutes to warm up include: 1. Increased fuel consumption; 2. More carbon deposits; 3. Air pollution. The harm of not warming up the car is: Engine wear, as the engine oil settles at the bottom when the car is cold, leaving the engine internals in a state of dry friction. The method to warm up the car is: After starting the vehicle, let it idle for 1 to 2 minutes until the engine coolant reaches normal temperature, then you can drive. The purposes of warming up the car are: 1. After the car has been parked for a long time, the engine oil flows back into the oil pan, leaving the upper part lacking lubrication. Warming up the car serves to lubricate it; 2. When the engine has not reached its operating temperature, the fuel supply system cannot effectively vaporize the gasoline completely due to the low temperature. Warming up the car can improve efficiency; 3. It helps the transmission gear oil to lubricate the upper part of the transmission.
