Inspection Plate Injector Timing, Small Engine

[Spewing]

I posted this but its already getting Buried in other post. So here it can not get buried.

This is the device in which will trigger the injector, perhaps toggling the reset pin on a 555 timer with a very long delay.

There want be any electronics controlling the injector, There is no room for electronics in the time barrier.

At 800 rpm idle, the valve only opens for 37 Milliseconds, "about the time it takes to blink your eye one time." So the Injector Tuning set screw will be wired directly to the coil of the relay switch. When there is no power to this relay the injector will be open. When the valve is touching the set screw the valve will remain shut.

How do you regulate your flow rate, or amount of injection if there are no electronics? Well, even if you used electronics you still couldn't regulate your flow rate beyound 37 ms at idle. The answer to this question is you regulate the flow rate in which flows during idle by adjusting the amount of PSI located in the storage area. The higher the psi the more the flow rate. So you may find that with a 1.5 MM opening at the tip of the injector you must maintain 13 and 3 quarter pound pressure to deliver 2.6 cc's of hydroxy gas in that 37 ms.

If you rev the engine up you no longer have 37 ms, The higher the rpm's the shorter length of time you have to inject the gas.

If your injecting 2.6 cc's per opening at 13 pound pressure at 800 rpms and you want to go up to 2000 rpms and inject the same amount of gas, you will find that you have to allow the psi to rise to about 25 psi to inject 2.6 cc's at 2000 rpm's. You use your pressure to control your flow rate, there is no electronics needed to do this, and if you wanted to use electronics to control it you wouldn't be able to because there is simply no time for it period!


The key to controlling the flow rate or amount of gas injected is found in your injector exit port size, and mainly your psi. If you have an 1/8 th Exit port and your wanting to diliver 2.6 cc's of gas on idel, you may require only 10 psi, if you use a smaller hole size you must have an higher psi to dilivere the same amount of gas. So you can see how your injectors exit port is related to the psi you'll be using and your flow rate.

There will come this formula, My Exit port hole size is 1.5 mm, and i need to inject 2.4 cc's in 37 ms. How much Psi is required.
