Water Injection Nozzle Calculator

	Injector Flow Rate at 3 bar (CC/min)
	Injector Rated Pressure (bar)
	Peak Injector Duty Cycle (%)
	Fuel Rail Pressure (bar)
	Number of Injectors
	Calculated Fuel Flow (CC/min)
	Desired % of Fuel to be Injected (12% for efficient set-ups (Big IC/Big Turbo) to 17% for high-temp (aggressive) set-ups)
	Calculated TOTAL WATER FLOW (CC/min)
	Desired % Methanol of the Mixture (%)
	Calculated TOTAL FLOW REQUIRED (CC/min)
	Pump Pressure (psi)
	Max Manifold Pressure (psi)
	Number of Jets Installed
	Flow of Jet Required (CC/min)
	(gallons/hr)

Total Flow: —

200	300	400	500	600	700	800	900	1000	1100	1200	1300

Flow of Each Nozzle: —

200	300	400	500	600	700	800	900	1000	1100	1200	1300

* Flow of each nozzle is what it would measure if flowed for 1 minute on the bench in open air/atmospheric pressure
