| 主权项 | 1. A method of operating a direct injection fuel pump, comprising: regulating a pressure in a compression chamber of the direct injection fuel pump to a single substantially constant pressure during a direct injection fuel pump compression stroke, the pressure greater than an output pressure of a low pressure pump supplying fuel to the direct injection fuel pump; and commanding a solenoid activated check valve at an inlet of the direct injection fuel pump to a pass-through state during the direct injection fuel pump compression stroke. | ||
