How is the pulse width of a fuel injector determined?

In terms of engine mechanics, the determination of fuel injector pulse width is fairly simple. First, you determine the base pulse width by looking in a reference table where the relation between engine speed and load is explained.

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.

How does the engine control unit control the injector pulse?

Question: What controls the fuel injector pulse? Ans: The engine control unit is the electronic brain that used to control the fuel injector pulse by gathering data from various sensors along the fuel line

How does the fuel injector work in a car?

All modern gas-powered automotive engines use fuel injectors to deliver fuel to the combustion chamber. Varying loads, speeds, and temperature conditions require the fuel delivery to be adjustable, and that is accomplished through changes to injector pulse width.

How do you check injector pulse?

you can check for injector pulse with a test light, simply put the test light between the 12v pin and the trigger wire on the injector plug and crank the engine, it will flash each time it pulses.. easy….

How can I tell if an injector is bad?

Start the engine and allow it to reach normal operating temperature.
Check the temperature with the spray bottle of water if an infrared sensor is not available. Spray water on the exhaust manifold where it attaches to the head.
Raise the rpm of the engine if the exhaust manifold runners are to close to call.

What are symptoms of an injector problem?

9 Common Bad Fuel Injector Symptoms Rough Idle or Engine Stalls. Because your vehicle is not getting enough fuel or an uneven supply of fuel, the RPM while idling drops below the optimal level Engine Vibrates. A faulty fuel injector will cause the corresponding cylinder to not be able to fire. Engine Misfires. Check Engine Light Turns On. Fuel Leak. Fuel Odor. Engine Surge.

What are the symptoms of a faulty fuel injector?

– Rough Idle or Engine Stalls. Because your vehicle is not getting enough fuel or an uneven supply of fuel, the RPM while idling drops below the optimal level and results in a rough or even violent idle. If the RPM falls too low, the car will actually stall and you will need to restart…
