20 msec = 0.0003333 minutes
(5 minutes/mile) / (0.0003333 minutes/pulse) = 15000 pulses/mile?
Does that sound logical? Seems high compared to the values in the Guino wiki...
Trying to convert the fuel injector graph to usable data seems a bit more difficult. First, the graph states that the given conditions are "at idle." That could be anywhere from 800 RPM to 1,200 RPM. There's also no flowrate information for mgal/pulse that could be used to calculate how many pulses/gallon (which makes more sense to me than microseconds per gallon... how does that work anyway?)
Can anyone with better math skills than me chime in? Anyone have the teacher's manual  |
It's not 20 msec/pulse, it's 20 msec/DIV....I think they mean per division on the graph. Going by that, the pulses appear to be approximately 25 msec long. Also, that time is probably time per pulse HIGH....not including time LOW. So, HIGH + LOW according to the graph seems to be.....more like 60 msec/cycle.
300 secs/mile @ 12 MPH......300,000 msec.......(300,000 msec/mi) / (60 msec/pulse cycle) = ~5000 pulses/mile...
Is that more in line?
