摘要:
An internal combustion engine for a motor vehicle is provided with a crankcase that contains lubricating oil and on which a cylinder block with several cylinder bores is arranged. The cylinder bores are closed with a cylinder head that is arranged on the cylinder block and features cylinder head covers for covering a valve mechanism mounted on the cylinder head. Means are provided for guiding a dipstick that serves for determining the filling level of the lubricating oil. The means for guiding the dipstick are realized in the form of cast channels that extend through at least the cylinder head and the cylinder block. The upper outlet of the channels is provided for inserting and removing the dipstick in the region of one cylinder head cover.

摘要:
Method for determining, with geodesic precision, the position of a target point on a target object by using a geodesic measuring device, said method comprising a sighting device which comprises at least one objective unit that defines an optical line of sight, an electronic distance measuring unit, and a thermal imaging camera for recording a thermal image in the direction of the optical line of sight. An angle measuring function is provided for recording the line of sight alignment, and a control unit is provided for controlling the angle measuring function, the thermal imaging camera. In a thermal imaging mode when a measurement procedure is triggered, position data of the sighted target point which are determined in said measurement procedure are linked to temperature information which is read out from the thermal image for the target point at which the line of sight is aimed.

摘要:
A cylinder head arrangement is provided for an internal combustion engine of a motor vehicle. The cylinder head arrangement includes, but is not limited to a combustion chamber, a first intake valve in a first intake port, as well as a first exhaust valve in a first exhaust port and a second exhaust valve in a second exhaust port (19). The second exhaust port is realized in such a way that a gas flow from the second exhaust port back into the combustion chamber results in an at least partially swirling flow in the combustion chamber.
