Abstract: A fuel injector has a seat and at least one seat passage. The seat includes an outer tip surface through which the seat passage extends. A non-thermally conducting coating is provided on at least a portion of the outer tip surface and not on surfaces defining the seat passage. The coating is constructed and arranged to be heated by combustion gases so that the outer tip surface reaches a temperature greater than a temperature that the outer tip surface would reach if the coating was not provided so as to cause evaporation of fuel that contacts the outer tip surface, The seat passage is constructed and arranged to not be substantially heated by conduction from the outer tip surface and to be cooled by fuel passing there-through so as to prevent deposits of combustion from accumulating on surfaces defining the seat passage.

Abstract: A switch valve includes a fixation portion and a water diversion plate, the fixation portion, a water diversion cavity connected to an inlet waterway, at least two diversion waterways, and a water diversion plate. A universal driving shaft is rotatably connected to the fixation portion and is inserted to the water diversion cavity. The driving mechanism is connected to the universal driving shaft. The water diversion plate and the universal driving shaft rotate synchronously. The bottom of the water diversion cavity is fixedly disposed with a first gear ring. The water diversion plate is fixedly disposed with a second gear ring which engages with the first gear ring. When the driving mechanism drives the water diversion plate to rotate in a preset angle, it slides along the universal driving shaft. The inlet waterway is switched to connect to the diversion waterways by the rotation of the water diversion plate.
