With a total of 2 patents, Hollowell's work has had a meaningful impact on the efficiency and performance of fuel injection systems.

Latest Patents

Hollowell's latest patents include a fuel injection timer and current regulator. This innovative fuel injector control system provides precise fuel injection timing while eliminating the need for a voltage regulator. The system estimates or predicts ramp times between voltage application and actual fuel injection. In one embodiment, an estimated ramp time injection is calculated from a measured voltage, which is then used to delay or advance the application of voltage on the coil. This ensures that the load current reaches a desired level at the appropriate injection start time. In another embodiment, an actual ramp time for a given injection is measured to predict future ramp times. Additionally, a current regulator is incorporated to prevent excessive emissions during load current control.
