4. Combining the injection system with the combustion chamber
4.1 Direct injection system
The type of injector best suited to the direct injection engine is usually the perforated injector, which distributes the fuel efficiently throughout the combustion chamber.
The number of holes depends on the shape of the combustion chamber, as well as on the rotation of the air (also known as "swirl" or "nd/n"), which is characterized by the ratio between the rotational speed of the air in the cylinder at the start of compression and the rotational...
