| Fuel flow rate through an injector is affected by a number of different things. This page focuses on the effects of base fuel pressure and its influence on injector deadtime. | Fuel flow rate through an injector is affected by a number of different things.

| - | Flow rate through an injector is substantially influenced by the pressure differential across the injector. If we assume that a given injector has been rated at the industry standard of 3-bar (43.5 psi), then the well-known formula for calculating the effect of changing fuel pressure is below. | + | Flow rate through an injector is substantially influenced by the pressure differential across the injector.
