For years, the standard injector sizing formula took horsepower, number of injectors, Brake Specific Fuel Consumption, and injector duty cycle to determine the best injector jeep 1999-2018 fic flow matched injectors sizes 19lb, 24 lb, 27 lb, 30 lb, 36 lb, 42 lb, 48 lb, 52 lb, 60 lb, 72 lb, 80 lb pick your size $39. Mar 25, 2012 Fuel pressure can be raised to increase the rate of fuel flow but this should not exceed 60 psi in most cases. All other cells are calculation cells. Despite the high flow rate, they are linear and controllable at low pulse widths compared to other extreme flow injectors! The computer is programmed to tell the fuel injectors what to do at that very point on the fuel map, and it sends out the appropriate message -- without any more input from the driver. Unlike a typical solenoid-driven or HEUI-style injector, a Piezo stack injector can operate at very high speeds (0-400 micro seconds), allowing multiple injection events per engine cycle. 0 *(17. All Fiveo fuel injectors The graph shows the pump’s maximum possible flow rate is at free-flow (160 GPH), yet we know the maximum flow rate while under actual operation is going to be much less. Electrical control signal from the computer activates the solenoid causing the valve to move off its seat, allowing fuel to flow in a conical spray pattern. Picking the proper fuel injector size is critical for performance and tuning control. 12 0. While standing on the left side of the motorcycle, the part number on the rear fuel injector can be easily read with the aid of a flashlight. 91 flow rate, one happens to be a 8*spray pattern and the other a 25* spray pattern. fuel injector flow rate chart
