VOLTAGE SUPPLY MODULE CONTROL FOR A FUEL INJECTED ENGINE
DRIVE
May 22, 2025
An apparatus for controlling power for a fuel injector includes a fuel injector configured to inject fuel to a cylinder of an engine and a powertrain control module generating a bypass enable signal or a boost enable based on the engine cranking signal. A bypass voltage circuit is electrically coupled to the fuel injector and is configured to provide a system voltage of a vehicle to the fuel injector during a bypass enable signal. A boost voltage circuit is electrically coupled to the fuel injector and configured to increase a system voltage of a vehicle to a boosted voltage during the boost enable signal, wherein the boosted voltage is higher than the system voltage.
