Need to warm up the engine before driving a car?

It is a habit and gradually becomes the principle of many drivers. But is it really necessary?

Jason Fenske of the YouTube channel Engineering Explained, argues that it is not necessary to warm up a car engine before driving.

Idling before moving is no longer necessary in cars thanks to the fuel injection system in the engine.

According to Fenske, current car manufacturing technology with fuel injection systems helps drivers skip the "idling" operation before starting the journey. The advantage of this system is that it is controlled by computer. It helps the process of mixing fuel and air to take place quickly. The mixture reaches the ideal ratio for the engine's work process right when starting. The intake air temperature is also calculated to optimize the fuel combustion process.

The above advantages are not available in cars with traditional carburetors. Warming up the engine before driving is essential, especially in countries with low or freezing temperatures.

However, skipping the warm-up does not mean “forcing” the engine to operate at high intensity immediately. To avoid unnecessary wear on engine parts, it is better to run the vehicle at moderate speed when starting to move. This short period of time is to wait for the lubricating oil to reach the required temperature and move fully to the engine parts.
