  • Diesel exhaust fluid system
    Patent number: 10371030
    Abstract: An exhaust gas purification system includes a tank for storing a fluid and a mounting plate coupled to the tank. A baffle is positioned inside the tank below the mounting plate. The baffle has an outer wall defining an interior cavity and an opening. A sensor is positioned in the interior cavity for detecting a condition of the fluid. A supply conduit extends through the mounting plate into the tank. A return conduit extends through the mounting plate into the tank and has an outlet positioned to discharge a return fluid below the opening and exterior to the baffle and the interior cavity.
    Type: Grant
    Filed: September 30, 2016
    Date of Patent: August 6, 2019
    Assignee: DEERE & COMPANY

  • Internal combustion engine charge air cooler precooler
    Patent number: 8813489
    Abstract: A work machine having an air-breathing, fuel-consuming, liquid-cooled internal combustion (IC) engine and a turbocharger receiving combustion products from the IC engine and a compressor for pressurizing air to the IC engine. A primary heat exchanger is in fluid flow connection between the compressor and the IC engine and a secondary heat exchanger is in fluid flow connection between the compressor and the IC engine and is upstream of the primary heat exchanger. The secondary heat exchanger is an air-to-liquid heat exchanger and receives liquid coolant from the IC engine.
