ELI5: Explain Like I'm 5

Direct fuel injection

Direct fuel injection is like giving a car a special straw that puts the gas right into the engine instead of spraying it in using a showerhead like in a regular car.

It’s like you have a cup of juice and you can choose to drink it by sucking it through a straw and getting it straight into your mouth. But, if you spill the juice into a bowl, you have to use a spoon to get it to your mouth.

When you put the juice through a straw, it reaches your mouth faster and more directly. The same thing happens with fuel in direct injection- it helps the fuel get to the engine faster and more efficiently.

By making sure more fuel gets into the engine, the car is more powerful and fuel efficient. This is because the fuel is being used more completely and can keep your car running smoothly for longer.
