Abstract
A method, comprising: operating an engine cylinder with fuel from a first injector and not a second injector and activating the second injector in response to a rail pressure increase of a fuel rail, the fuel rail coupled to the second injector. In this way, degradation of the second injector may be reduced by activating the second injector and allowing fuel flow through the second injector to reduce the pressure and temperature of the fuel rail.
