  • Patent number: 8100096
    Abstract: The invention concerns a method for automatically controlling an internal combustion engine, wherein, in a first controller mode, a charge air temperature controller is set as dominant for a map-controlled thermostatic valve, and, in a second controller mode, a coolant temperature limit controller is set as dominant for the map-controlled thermostatic valve. Upstream of a recooler, a coolant flow is divided into a recooler coolant flow and a bypass coolant flow as a function of the position of the map-controlled thermostatic valve. Downstream of the recooler, the temperature of the charge air cooler coolant flow is determined from the combined fractions of the recooler coolant flow and the bypass coolant flow to control the charge air temperature (TLL) or to control the coolant temperature (TKM).

  • Patent number: 8099956
    Abstract: The invention is based on an arrangement of supercharging units (1, 5, 6, 7), which arrangement is to be attached in the construction space of a motor vehicle, for supercharging an internal combustion engine with a fluid (23) comprising charge air and/or exhaust gas, wherein the supercharging units (1, 5, 6, 7) comprise at least one heat exchanger (5, 6, 7) and at least one compressor (1). According to the concept of the invention, the supercharging units (1, 5, 6, 7) are arranged combined in a module (10A, 10B) and, in order for the same to be kept together in the module (10A, 10B), the supercharging units (1, 5, 6, 7) are connected at any rate partially to one another in a fluid-conducting manner, and at least one of the supercharging units (1, 5, 6, 7) is held on a holding structure. This enables the supercharging units to be handled flexibly, simply and nevertheless in a manner saving on construction space and outlay on connection. The invention also leads to a production method.

  • Patent number: 8096347
    Abstract: A cooler block for an agricultural tractor comprising a cooler assembly mounted on a radiator and coupled to the radiator by upper and lower linkages. The cooler assembly can be moved between a first position in which the cooler assembly lies parallel to the radiator and a second position in which the cooler assembly is inclined relative to the radiator. The cooler assembly is pivotable about a pivot in the upper linkage that is itself movable relative to the radiator. The lower linkage allows the entire cooler assembly to rise and the pivot of the upper linkage to move away from the radiator as the cooler assembly is pivoted from the first to the second position. A detent is incorporated into one of the two linkages to retain the cooler assembly in the second position.

  • Patent number: 8061135
    Abstract: A condensate extractor system for an internal combustion engine assembly with a charge air cooler system is provided. The condensate extractor system includes a hose member with a first end in direct fluid communication with the charge air cooler system, and a second end in direct fluid communication with the intake manifold of the engine air intake system. The hose member removes condensate from the charge air cooler system in a continuous manner in response to a pressure gradient created by the throttle body when the engine is in an on-state. The hose member defines an orifice configured to restrict the flow of air and condensate through the hose member. A filter is placed in direct fluid communication with the hose member, upstream from the orifice. The hose member is preferably characterized by a lack of fluid communication with a reservoir configured to collect condensate.
