OEM Fueling System Overview:
Fueling System Overview
The OEM fueling system consists of several key components:
Direct injection injectors
Direct injection high-pressure fuel pump (HPFP)
In tank PWM-controlled low-pressure fuel pump (LPFP)
Engine control unit (ECU)
The high-pressure fuel pump (HPFP) needs to provide the injectors with a large volume of fuel to satisfy the desired air to fuel ratio. The injectors are only able to spray for a very small window of time, so the HPFP must provide the fuel at high pressures, upwards of 200 bar. In some instances, if the injectors are a limiting factor, they can be enlarged to reduce the time they need to spray. In other instances, the bore and or stroke of the HPFP can be increased to increase the volume of fuel displaced by the HPFP. By increasing the volume of fuel between the HPFP and the injectors, pressure behind the injectors increases and the amount of time the injectors need to spray decreases.
Unfortunately under some situations, the HPFP is capable of displacing a larger volume of fuel than it receives from the low pressure fueling system. As demand goes up, the low pressure fueling system needs to work harder to provide the volume of fuel necessary, but in some situations, the factory unit is unable to do so.
The APR LPFP increases the supply of fuel from the fuel tank to the HPFP to ensure the HPFP displaces the maximum volume of fuel possible during each stroke. This ensures the HPFP is capable of working at 100% capacity.
