[4] INJECTOR

General

The injectors inject high-pressure fuel sent from the

rail into the combustion chamber of the engine. 

The injections are controlled by the signal of engine's

ECU to produce the ideal timing, amount of fuel, mixture

and spray.

The  injector  injects  a  finely  turned  spray  in  three

pulses  during  the  combustion  stage.  First  a  small

amount is injected, mitigating the effect of the initial burn

and reducing NOx (oxides of nitrogen) and noise. The

main injection follows with the real burn, and in the last

stage,  a  diffuse  combustion  is  induced,  thus  reducing

particulate matter (PM) generated by the main injection.
