Abstract: An injector which incorporates the use of an insert to compensate for the change in volume of diesel exhaust fluid as the diesel exhaust fluid freezes, reducing or eliminating the effects on the calibration of the injector. The calibration freeze protection insert is located adjacent a calibration sleeve in the injector, where the insert is welded to an inlet tube. Any axial forces applied to the calibration sleeve from the blocking force of the freezing diesel exhaust fluid are transmitted to the insert, and the position of the insert is maintained by the welds. The insert and the calibration sleeve are configured to only allow small amounts of diesel exhaust fluid to migrate around the injector components, which is able to be compensated for by the elastic modulus of the various injector components.

Abstract: An internal combustion engine comprises a fuel injector 31, a spark plug 16, a piston 14 having a cavity 91, a swirl control device 95, and a control system 70. The cavity is formed so as to change in distance from the fuel injector to a side wall surface of the cavity, in the circumferential direction. The system performs ignition assist control for successively performing injections of main fuel and ignition assist fuel, makes an air-fuel mixture formed by the ignition assist fuel burn by flame propagation by the spark plug, and makes the remaining fuel burn by pre-mix compression self-ignition. The system controls the swirl control device during the ignition assist control so that when the engine load is high, the fuel sprayed heads toward parts of the side wall surface which are short in distances from the fuel injector.
