EGR valve

Greetings, many anticontaminating regulations in the engines reduce the power, the EGR, the PCV, the same catalyst, in some way or another what is sought is the fuel economy and comply with the regulations of monoxids to the environment. Now with electronic systems the moments in which each system acts without noticing the loss of power are controlled. Another example of how electronics wants to control the way we handle cars are electronic accelerator systems (Drive-Wire), in them the "blows" to the pedal, sudden accelerations are cushioned by the system in such a way that fuel is not wasted.
