Injectors, V6


Fuel is injected into the combustion chamber by the injectors. The amount of fuel and when it is to be injected is determined by the engine control module. This control module transmits a voltage and a time for the duration of each injection. In this way, the engine will receive the amount of fuel that has been precisely specified depending on the opening duration and pressure of the injector.
