Integrated fuel injector igniters having force generating assemblies for injecting and igniting fuel and associated methods of use and manufacture

摘要

Embodiments of injectors configured for adaptively injecting and igniting various fuels in a combustion chamber are disclosed herein. An injector according to one embodiment includes an end portion configured to be positioned adjacent to a combustion chamber, and an ignition feature carried by the end portion and configured to generate an ignition event. The injector also includes a force generator assembly and a movable valve. The force generator assembly includes a first force generator separate from a second force generator. The first force generator creates a motive force to move the valve between the closed and open positions into the combustion chamber. The second force generator is electrically coupled to the ignition feature and provides voltage to the ignition feature to at least partially generate the ignition event.

主权项

1. An injector igniter for replacing a diesel fuel injector in an internal combustion engine, the injector igniter comprising:
a valve movable between a closed position and an open position to introduce fuel into a combustion chamber of the internal combustion engine; an ignition feature positioned to generate an ignition event; a valve driver movable between a first position and a second position; a first solenoid winding configured to generate a magnetic field, wherein the magnetic field moves the valve driver from the first position to the second position to move the valve from the closed position to the open position; and a second solenoid winding, separate from the first solenoid winding, wherein the second solenoid winding is electrically coupled to the ignition feature, wherein the magnetic field generates ignition energy in the second solenoid winding, and wherein the second solenoid winding supplies the ignition energy to the ignition feature to generate the ignition event.
