7. Indirect injection or pre-chamber engines
The principle of this type of engine is to separate the combustion chamber into two parts:
a pre-chamber or turbulence chamber, usually located in the cylinder head, in which injection takes place;
a main chamber bounded by the cylinder head, cylinder and piston.
This type of engine is currently the most widespread for applications in passenger cars and small commercial vehicles.
