  • Publication number: 20230069392
    Abstract: A method of oil pre-conditioning for an electric powertrain for a vehicle configured to provide electric propulsion of the vehicle, said electric powertrain comprising the first electric motor being linked to the first gear module, a secondary shaft being linked to the second gear module, the second electric motor being linked to the third gear module through a motor shaft, the differential being shared by both electric motors, The electric powertrain is surrounded by an oil. The method includes the steps of selecting an oil pre-conditioning configuration wherein the secondary shaft does not rotate and at least one of the first electric motor or the second electric motor rotates while the other is in driving mode leading to the heating of the oil to reach a threshold temperature and applying the selected oil pre-conditioning configuration.

  • Patent number: 11300019
    Abstract: The present invention relates to a cooling jet nozzle (10) for an engine piston. The nozzle (10) comprises a cooling stream pathway (14), in which the internal cross-sectional dimensions of the pathway vary along the length of the pathway; and a plunger (28) located within the cooling stream pathway to impinge a cooling feedstream received within the pathway to provide a cooling jet. The plunger (28) is axially moveable within the pathway to adjust the internal cross-sectional dimensions of the cooling jet.
