Abstract:
1. A system for injecting a water/alcohol mixture into a boosted internal combustion engine, the system comprising: a reservoir adapted to contain the water/alcohol mixture; a fluid pump, the fluid pump being fluidly coupled to the reservoir; a pump controller including a sensor adapted to measure a boost level, the pump controller being electronically coupled with the fluid pump and adapted to control the operation thereof based on boost pressure levels; a nozzle, the nozzle being fluidly coupled with the pump; and a safety device discreet from the pump controller, the safety device being electrically coupled to the pump controller and including (i) a fluid flow path located between the pump and the nozzle and, (ii) a flow meter circuit being adapted to measure the rate of fluid flow through the fluid flow path and transmit a voltage signal based on the measured flow through the flow meter.
