Ls injector duty cycle
Those injectors, maxed to their extreme limit (100%), will support approximately 420HP* at stock fuel pressures. You don’t want to push the injectors beyond 80%-85% duty cycle though for reliability reasons. The ID2000 has set the standard for linearity and control in a large injector. Flowing in excess of 2000cc/min at 3 bar, the ID2000 will also provide a smooth stoichiometric idle on E85, and it will do all this while maintaining strict linearity up to 95% duty cycle at 9000rpm. Jun 14, 2010 · Therefore lower fuel pressure at low speeds increases duty cycle improving idle quality, and higher fuel pressure means a fuel injector is capable of making more power at a given duty cycle. The LS9 takes this to a whole new level running a dual pressure system which runs at about 37 psi, before jumping all the way to 87 psi!
The fuel injector duty cycle (IDC) is the percentage of time the injector is supplied with power. The time during which the injector is powered (or activated) is called the injector pulse width (IPW). During normal engine operation, the fuel injector fires once during the four strokes of the Otto cycle, which last for 2 revolutions of the engine. Reliable and Durable. The TNV engines now proudly take up the running as YANMAR’s premium small industrial diesel. They offer even more enhanced durability due to better block cooling, a stiffer crank and pistons, finer tolerance in the journal, and more. CAE analysis has brought lower vibrations and higher strength to the mounting structure... The injecters you have are 42lb's so you won't have to change them IMHO there the same as the injectors in the LS7's and thats what I have in mine. You will hit over 90% duty cycle with the cam you have but thats only right up top so they should be fine it should be fine. Machined Billet Injectors and Nozzles AEM includes one precision-machined billet injector in its gasoline Water/Methanol Injection kit. It features an integral check valve to prevent unintended fluid flow. Three billet injector nozzles are included for matching water/methanol flow to an engine’s horsepower output. Use the fuel injector flow rate calculator to calculate flow rate, pressure and horsepower for gasoline, race gas and e85 (ethanol) with a base fuel pressure of 3 Bar (43.5 psi) and a maximum injector duty cycle (IDC) of 80%.

Base Pulse Width is time injector is open compared to how much time is available at RPM, so back to why Duty Cycle is so important, Injector Pulse Width in percent of time open in M/Sec changes with RPM = time gets shorter.
Jan 31, 2000 · The additional injectors will feed the additional fuel needed to run above 15psi boost, which is where I'm told the stock injectors reach their maximum duty cycle (Jim Labreck, 4/28/98). Instead of this option, you can opt to upgrade the stock injectors to 750cc's to get the proper amount of fuel needed for running at 15psi and higher. Nov 24, 2011 · The duty cycle is the period from the beginning of trying to open the injector until the point the injector closes. The dead time is included, and if you have the dead time wrong your table would command a different amount to get the AFR correct.
Some more info about the Injector Dynamics ID2000 For 5.0 Coyote Engines. The ID2000 has set the standard for linearity and control in a large injector. Flowing in excess of 2000cc/min at 3 bar, the ID2000 will also provide a smooth stoichiometric idle on E85, and it will do all this while maintaining strict linearity up to 95% duty cycle at ...
