  • Patent number: 11274617
    Abstract: A system includes an engine adapted to output a torque, a parasitic load adapted to receive a portion of the torque from the engine, and a controller communicably coupled to the parasitic load. The controller is configured to determine an actual exhaust temperature value of an exhaust gas flow exiting the engine and a minimum fuel amount to be injected into the engine. The controller is configured to compare the actual exhaust temperature value with an exhaust temperature threshold value of the exhaust gas flow to determine a first difference between the actual exhaust temperature value and the exhaust temperature threshold value. The controller is configured to determine a target torque output of the engine based on the first difference and the minimum fuel amount. The controller is configured to cause the torque to be increased to attain the target torque output using the parasitic load.

  • Patent number: 3946230
    Abstract: An original and a heat sensitive member are inserted as a sandwich into a copying machine and fed past a combined imaging and transfixing or fusing station where radiation is applied to the sandwich to thermally impart a latent image of the original to the heat sensitive member. Thereafter, the original is separated from the heat sensitive member and ejected from the machine. The heat sensitive member on the other hand, continues onwardly to a developing station where toner particles are applied to develop the latent image. Next, the heat sensitive member loops back towards the imaging and transfixing station, and a copy medium is brought into engagement with the developed image. The copy medium and the heat sensitive member are then passed into the imaging and transfixing or fusing station.
