Technical data
I used a 12V fuel injector for a Citroen C3, a small European car that has a 4 cylinder petrol engine. The injector type is 01F023. I bought it for about €10 (US$10) on a Chinese web shop.
I marked the + connection on the housing. If you swap the polarity, the injector will not be damaged and not work.
The fluid consumption was measured running the injection system at 5 Hz. The (2L) Garden sprayer was half filled and brought on pressure using one stroke of the pressure pump. Then the fluid consumption was measured by spraying 1 hour at different pulse times (milliseconds). The weight of the sprayed fluid was used to calculate the fluid consumption (milliliter / hour). I normally run at 5Hz and 1 millisecond pulse time.
| pulse time | fluid consumption |
|---|---|
| ms | ml/h |
| 1 | 6 |
| 2 | 10 |
| 5 | 15 |
| 25 | 68 |
This injector should last in a car running at 120 km/h (3000 RPM) at least 120.000 km, that is 1000 hours. In a 4 stroke petrol engine it runs at 1500 pulses/min, 25 Hz. So at 5 Hz the injector should last 5000 hours.That is more than half a year continues running.
