According to my calculation:
For HSV to deliver water properly you need to match its operating frequency to engine RPM. Since my set up is single HSV and its 4 cylinder engine with 4 nozzles (one per each intake) at 6000RPM HSV will operate at 50HZ (6000RPM -> 100RPS -> 50RPS to draw water from all 4 intake tracts -> 50HZ valve speed). This is not ideal (as ideal would be to have 4 x HSV operating at 50HZ each) but feasible compromise between HSV cost and performance.
The system must be matching frequency due to misting nozzles positioned next to intake valves and there is no chance for mist to be homogenized with air evenly. Offsetting HSV operating frequency in relation to intake strokes will cause over-delivery of water per some intake strokes and shortage of water in others.
Richard, am I correct in calculations?
In order to controll HSV using "peak and hold" style drive i need to know operating parameters. I can have only 12.5VDC for activation but what is recomended "hold open" voltage?
