摘要:
An air guiding system for a vehicle, particularly a passenger car, that is arranged in a rear area of the vehicle and has at least one central main air guiding element displaceable from a moved-in inoperative position into a moved-out operative position. Lateral auxiliary air guiding elements are displaceable together with the or each central main air guiding element. The lateral auxiliary air guiding elements can be rotated like a folding knife with respect to the or each central main air guiding element in order to change them from an also moved-in inoperative position into an also moved-out operative position.
摘要:
A method for adjusting and maintaining a desired room climate with regards to temperature, humidity, and carbon dioxide concentration at a given charge of heat, humidity, and carbon dioxide. A proportionate amount of outer air is cooled to a saturation temperature and then dehumidified. The saturation temperature results from the intersecting point of the saturation curve of humid air, and a straight line which extends through the point of state of the air being in the state of the desired climate of the room air, and the point of state of the available outer air in an h,x diagram, i.e., provided with a rise of the quotient of the heat charge in relation to the humidity charge.

Method for determining changing ice concentration in binary ice volumes with the steps: carrying out mechanical work in the volume to be measured with an electric motor, determining the electric power and mathematical conversion into a measure for the ice concentration.
摘要:
Method for determining the ice concentration in a liquid ice mixture (binary ice fluid), with the steps: separating a partial flow of the fluid and introducing and heating the partial flow into a heat exchange (16) until complete melting takes place, accompanied by the measurement of the inlet temperature tA and outlet temperature tB, further heating of the fluid flow by an external heat source and return of the partial flow through the heat exchanger (16), accompanied by the measurement of the inlet temperature tC and outlet temperature tO of the return partial flow and calculating the ice concentration according to the equation Xice=(tC−tO−tB+tA)·(cpfluid/hice), in which cpfluid is the specific heat capacity of the binary ice fluid and hice is the enthalpy of fusion of the binary ice.
摘要:
A method for operating an internal combustion engine is described. A base controlled variable for influencing an actual value of an operating variable of the internal combustion engine is ascertained. The actual value of the operating variable is compared to a setpoint value of the operating variable. A correcting variable is ascertained as a function of the comparison. A controlled variable is ascertained as a function of the base controlled variable and as a function of the correcting variable. An actual value of a state variable of the internal combustion engine is ascertained. A start point in time of a time interval of a critical state change of the internal combustion engine is ascertained as a function of the ascertained actual value of the state variable. The controlled variable is essentially ascertained from an intermediate controlled variable and a correcting variable following the start point in time.
摘要:
A fixture (1) for adjusting an air guiding device (2) on a motor vehicle, comprising at least one linear adjustment device (3) for adjusting a linear deployment of the air guiding device (2), and at least one angle adjustment device (4) for adjusting an angle of attack of the air guiding device (2), wherein the adjustment devices (3, 4) are connected to the air guiding device (2) in a force-transmitting manner for adjustment of same.

A motor vehicle, especially a passenger car, is provided with an air-conducting device arranged in its rear area. The air conducting device can be moved by way of an adjusting mechanism from a rest position flush with the adjacent body of the rear area into a driven-out operating position. The adjusting mechanism includes two openers arranged in side areas of the air-conducting device for moving the air-conducting device. In order to be able to adjust an air-conducting element continuously from a lowered rest position and a raised operating position, each opener is connected via a swivel-joint on a bearing part that is fastened to the vehicle and aligned vertically.

In a rear end of the vehicle body, an assembly carrier which is arranged in the vehicle transverse direction is inserted between inner body-side side parts of the vehicle rear end. The assembly carrier holds pre-assemblable components and to which assembly carrier is fastened a rear-end trim panel and which assembly carrier is fixedly connected to the two inner side parts by screw devices and forms a stiffening body cross member.
摘要:
An air guiding system for a vehicle, particularly for a passenger car, is arranged in a rear area of the vehicle and has at least one central main air guiding element that can be displaced from a moved-in inoperative position into a moved-out operative position. Lateral auxiliary air guiding elements are displaceable together with each central main air guiding element. The lateral auxiliary air guiding elements can be rotated with respect to each central main air guiding element about a respective pivot fixed to the main air guiding element in order to change them from an also moved-in inoperative position into an also moved-out operative position.
