How to make a simple signal injector circuit?
Simple Signal injector circuits When see in simple signal injector circuit as shown figure this below, he used two transistors join together to be astable multivibrator which has a signal output frequency of 1,000Hz in square waveform. A power supply voltage of this circuit is 1V to 5V.
Is there an injector pulse on my car?
SOLVED: I have no injector pulse. I have plenty of fuel – Fixya I have no injector pulse. I have plenty of fuel pressure and both crank sensors and the cam sensor are good. If I spray carb spray through a vacuum hose, it runs fine, but I’m getting nothing through the injectors.
Where does the spark come from on a wire COP Coil?
Each Transistor (within the each ignition coil) needs this Triggering Signal to know the exact time to make the ignition coil spark. This high frequency pulse that we’re calling the Triggering Signal comes from the ECM (Fuel Injection Computer) and can only be measured with an oscilloscope or a Digital Multimeter that can read Hertz frequency.
What kind of power supply do I need for signal injector?
A power supply voltage of this circuit is 1V to 5V. We recommend a AAA 1.5V-battery, it makes a level amplitude voltage peak at the output lower than 1Vp-p.
What are the input signals in a pulse injector?
These are the Ne, G, and IGf signals. Inside the ECU, the Ne Signal is used to produce an injection chive signal. The G signal is used to determine the timing of the injection signals. The IGf signal is monitored for fuel delivery fail-safe. (With Conventional EFI, the IG signal is used to produce the injection drive signal.)
What does it mean when there is no injector pulse?
In case of that, there is no injector pulse or spark, this means that is your ECU has failed in operating in this case you have to get your ECU changed or visit an expert.

What happens if there is no injection signal?
The ECU cannot pulse the injector without an Ne signal and will not start or run if this signal is not present. If the G signal is not present while cranking the engine, the ECU will not be able to identify when to produce the injection signal. The result will be the same, no injection pulse.
What kind of fuel does a spark ignition engine use?
We have seen two types of fuel system, fuel injection system in diesel engine and petrol or octane run the engine. We have a focus on the Spark Ignition engine (SI Engine), which is run by Octane or Petrol. What is Fuel Injector?
