  • Combustion engine housing having cylinder cooling
    Patent number: 11187181
    Abstract: A combustion engine housing with cylinder cooling includes at least one cylinder. The cylinder cooling channel has a distribution cross-sectional area having a cross-sectional area through which coolant can flow, in a first cross-sectional plane that is perpendicular to the cylinder axis. In a second cross-sectional plane, which is perpendicular to the cylinder axis and which is arranged in relation to the vertical direction between the first cross-sectional plane and the coolant outflow opening, has a throttle cross-sectional area, which is a cross-sectional area through which coolant can flow. The throttle cross-sectional area is smaller than the distribution cross-sectional area.

  • Internal combustion engine with split cooling system
    Patent number: 10287966
    Abstract: An internal combustion engine, in particular for a vehicle, is provided. The internal combustion engine has a crankcase, a cylinder head, a coolant feed line, a cooling channel branching line, a first coolant channel which runs at least partly through the cylinder head, and a second coolant channel which runs at least partly through the crankcase. The coolant feed line is connected to the cooling channel branching line to supply coolant. The first and second coolant channels are each connected to the cooling channel branching line to be supplied with coolant from the cooling channel branching line. The cooling channel branching line is equipped with a temperature-sensitive current regulating device which is configured to variably adjust the ratio of the coolant volumetric flow rates that are from the cooling channel branching line into the first and second coolant channels over a range on the basis of the temperature.

  • Log splitter
    Patent number: 4081008
    Abstract: An upright free-standing log splitter operated by a vertical ram energized from any source desired such as a tractor to which the log splitter may be secured, or a trailer. The log splitter may be placed on a rear part of a truck or the like by means of parallel bars so that the splitter may be placed on the ground or raised for transportation. Wheels may be provided for the working platform or bed of the splitter so that it may be trailered.
