Re: Controling individual cylinder WI with PWM
It will be difficult to implement a mutlipoint-sequential injection set up base on our existing components.
1. The FAV has to have quite low flow - around 500cc/min per manifold runner. 1300cc/min is our standard issue.
2. Detection an individual blocked jet require multiple flow sensors. Th=It is difficult to make a turbine base flow sensor that reads below 100cc/min.
3. Driving the FAV can be shared/parallel electrically with the fuel injectors if the coil impedance is matched.
Anyone of our system can receive a PWM signal form your ECU, frequency between 50-400Hz.
Water injection is rarely needed before boost. Once on boost, air speed is quite fast, distribution is not too much of a problem if the can be placed at the exit of a FMIC. Droplet distribution will even themselves out along the journey upstream.
If you are running a large amount of water, then consider a 5-jet setup, four at the runners and one at the exit of the IC. Due to the pressure differentials between the two banks, checkvalve jet is preferred.
