  • Patent number: 12071884
    Abstract: A transmission system selectively coupled to an engine crankshaft of an internal combustion engine arranged on a vehicle includes a transmission, an aftertreatment system, an accessory device and a controller. The aftertreatment system reduces emissions in an exhaust of the internal combustion engine. The accessory device is configured to provide power. The controller operates in an aftertreatment heat-up mode such that the aftertreatment system is heated up to an elevated temperature and emissions are thereby reduced based on the elevated temperature. The controller is configured to heat up the aftertreatment system to reach between one (1) and two (2) kilowatt hours (kWh) of enthalpy before two minutes at engine startup by (i) operating the internal combustion engine in cylinder deactivation mode (CDA); (ii) operating the internal combustion engine at an elevated idle speed; and (iii) operating the accessory device at a threshold power.

  • Patent number: 11946482
    Abstract: A vacuum pump and a washer which can reduce vibration of a rotor and the rotor which can reduce the vibration are provided. When an inertia moment ratio which is a ratio between the inertia moment around a z-axis and the inertia moment around an x-axis or a y-axis is larger than 1, a natural frequency ?2 does not match a rotational frequency ?z but goes away from that. When the natural frequency ?2 matches the rotational frequency ?z, the rotor vibrates and thus, a fatigue failure occurs in a rotor blade. When the rotor is to be made larger in a radial direction of a rotating shaft, a value of the inertia moment ratio is set to a value larger than 1.
