  • Publication number: 20240083410
    Abstract: Disclosed are a hybrid electric vehicle and a method for controlling an engine speed of a hybrid electric vehicle. In particular, the method includes: determining, when an engine on one end and a first motor are directly connected and while driving in a state where an engine clutch is connected and a second motor is connected to the other end, a compensation value based on the difference in the rotational speed of the engine and the second motor when a control entry is caused, which induces the rotational speed mismatch of the engine and the second motor; and compensating an output torque of the first motor based on the compensation value.

  • Patent number: 11927100
    Abstract: The present invention relates to a method of manufacturing a labyrinth sealing device mounted between a diaphragm and a turbine rotor of a turbine in order to induce smooth rotation of the turbine rotor and prevent a leakage of gas by minimizing friction between a rotor, such as the turbine rotor, and a stator, such as the diaphragm, when the rotor rotates in the stator, wherein the labyrinth sealing device includes a ring-shaped body and a labyrinth part protruding from one surface of the ring-shaped body, the ring-shaped body is manufactured by centrifugal casting or ring mill, and the labyrinth part is manufactured by 3D printing. The method of manufacturing a labyrinth sealing can improve productivity by reducing material costs and machining costs by manufacturing the labyrinth part (or teeth) protruding from the ring-shaped body using three-dimensional printing after manufacturing the ring-shaped body by centrifugal casting or ring mill.
