A popular belief among car owners is that they need to let their car warm-up for several minutes before setting out on their drive. The idea behind this is to let the car\u2019s engine get up to temperature by running idle for a few minutes, all to protect the engine\u2019s longevity and performance. The reality of things, however, are different. Idling your car for a few minutes wastes not only your time but also wastes valuable fuel.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

It\u2019s advice from the carburetor age!<\/h5>\t\t\t\t<\/div>\n\t\t\t\t

Whoever told you that you need to idle your car on a cold morning to \u201cheat things up,\u201d could be stuck in a bit of a time warp. Before 1980, most cars had carburetors, and these engines did need to warm up in the winter. Why? Carburetors regulated the air-fuel mixture within the engine and could not accurately adjust the air to fuel ratio in cold weather.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Electric Fuel Injection Systems<\/h5>\t\t\t\t<\/div>\n\t\t\t\t

Nowadays, practically every car sold in America has an electric fuel injection system that helps maintain the perfect air-fuel mixture needed for a combustion event, no matter the ambient temperature. Ergo, warming up the car before driving on a cold day has become a thing of the past. The sensors in your car\u2019s electronic fuel injection system are regulating the air-fuel mixture in real time, regardless of the temperature outside.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

It Causes Engine Damage:\u00a0Wondering why your check engine light is on? Could be due to engine damage from idling in the winter. \u201cIdling your car in the cold not only wastes fuel, but it\u2019s also stripping oil from critical components that help your engine run, namely cylinders and pistons,\u201d says\u00a0Stephen Ciatti, a mechanical engineer who oversees the combustion engine work at Argonne National Laboratory in Illinois. Less oil means more friction, more wear and tear, and a shorter life for your engine.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Since the 1980s, car manufacturers moved away from using carburetors to a more advanced system \u2013 the electric fuel injectors. As such, the car is fitted with sensors that measure the outdoor ambient temperature. This system allows the electric fuel injector to adjust the air-fuel mixture to account for the cold weather.<\/p>

Typically, an electric fuel injector will create a fuel-rich air-fuel mixture by releasing more gasoline, compensating for low evaporations levels.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Why Many People Think Idling Cars During Winter Is Paramount<\/h5>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Internal combustion engines run by mixing gasoline with air within the engine\u2019s cylinders. Once the air-fuel mixture is compressed, the mixture is ignited by the spark plug, which moves the pistons. In the years past, specifically before the 1980s, a carburetor controlled the mixing of fuel and air. One shortcoming of the carburetor was its inability to control the fuel in the air-fuel mixture precisely.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
