Abstract: In a balance shaft for a multi-cylinder in-line engine with at least two imbalance weight sections and at least one bearing structure wherein the balance shaft has imbalance weight sections being arranged symmetrically relative to the bearing position and at least one of the imbalance weight sections is connected to a further shaft section at an end facing away from the bearing position, a flexible coupling element that enables a deflection of the end of the connected imbalance weight section in the direction of the resulting centrifugal forces when the balance shaft rotates is provided between the end of the at least one imbalance weight section facing away from the bearing position and the further shaft section.

Abstract: In an internal combustion engine having a coolant circuit which comprises a first coolant line for the cylinder block and a second coolant line for the cylinder head of the engine, with the cylinder head having at least one inlet valve and at least one outlet valve per cylinder, an additional coolant duct provided in the cylinder head in close proximity to the valves is connected to the second coolant line for directly supplying coolant to the area of the cylinder outlet valves.

Abstract: In a motor vehicle comprising a vehicle body having a support structure for supporting a main drive unit and at least one support block disposed on the support structure by which the main drive unit is supported in the vehicle body, each support block comprises bottom and top parts which are movable relative to each other and provided with an operating mechanism for causing such movement for lowering the drive unit when the motor vehicle is involved in a collision.

Abstract: A unit carrier for secondary units of a motor vehicle internal combustion engine, having secondary unit attachment devices and engine block attachment devices. The unit carrier has a planned deformation point, which allows a relative displacement between the secondary unit and the engine block in case of a vehicle collision, if a predefined force is exceeded. The unit carrier is used in motor vehicles having a front engine arrangement.
