How does cold weather affect a car engine?

The engine requires extra fuel for starting so that, in spite of vaporisation and condensation problems, the engine still receives a combustible air-fuel mixture”. The components within an engine will also naturally shrink ever-so-slightly as it cools down, therefore tolerances decrease and the engine can become ‘tight’ as components contract.
Why is my car engine hard to start in cold weather?
Often times, this causes the oil to have problems at the time it circulates in the engine of the vehicle. Batteries loosestheir agility in cold weather.

Owners should start their car daily in zero-degree temperatures. Auto mechanics may advise starting a vehicle once a week to ensure continued battery life, but this is under the best circumstances.
Why does my car not start in cold weather?
In cold weather, engine oil becomes thicker and doesn’t flow as well, so moving the engine parts through it is harder. That means that your battery, which has been weakened by the cold, actually has to do more to get the engine moving so it can start. Reason 3: Cold weather can cause fuel problems

Auto parts stores and gas stations sell dry gas for gasoline cars and fuel conditioner for diesels, each to help combat fuel-line freezing and, in the case of diesel cars, gelling. Consider using a bottle of dry gas every now and then, or a conditioner with every tank of diesel.
When does cold, engine shakes and hesitates during acceleratio?
After the vehicle sits overnight (cold engine), during idle, engine vibrates and after about a minute vibration’s gone and comes back again a minute after – this cycle goes on and only stops when the engine becomes hot.
