  • Patent number: 7111608
    Abstract: A device for adjusting the loading motion of the intake air in internal combustion engines comprises a housing, which can be connected between an intake module and a cylinder head of an internal combustion engine, the surface of the housing facing the intake module having at least a first opening with a first inlet channel for a cylinder of the internal combustion engine and at least a second opening with a second inlet channel for the same cylinder of the internal combustion engine. Each second opening is provided with a helical valve that can be controlled by an actuator.

  • Patent number: 6138648
    Abstract: An intake device for a supercharged internal combustion engine is installed in a motor vehicle. In particular, the engine is a supercharged otto engine which can be installed in the rear of a motor vehicle, and has an air filter box which receives an air filter element, and a supercharger air cooler. The supercharger air cooler is integrated in the air filter box. In this way, optimal cooling of the supercharger air is assured even in the event that the otto engine and its supercharger as well as the supercharger air cooler are installed in the rear of the vehicle. Furthermore, in this way, the mounting, logistic, and test expenses, particularly at the manufacturing site, can be minimized.

  • Patent number: 5944000
    Abstract: In a venting arrangement for an internal combustion engine having a cylinder head with an intake duct structure consisting of plastic material and including intake passages, an inlet stub for connection to a vent pipe, and an outlet for communication with the intake passages, the intake duct structure includes a passage with a metal sleeve and a bolt extending through the metal sleeve for mounting the intake duct structure to the cylinder head while firmly engaging the metal sleeve with the cylinder head and a throttle structure which limits the vent flow from the inlet stub to the outlet intake ducts is formed in the passage adjacent the metal sleeve so as to be heated by the metal sleeve.

  • Patent number: 5713322
    Abstract: On an intake pipe (1) developed for an internal combustion engine of a motor vehicle which leads to an air filter housing (3), there is arranged on the outside on the intake pipe (1) a housing (11) containing an engine-control electronics. The housing (11) has a bottom (13) which is cooled by the stream of air in the intake pipe (1). In this way, despite the great closeness of the internal combustion engine, sufficient cooling is obtained of the electronic structural parts of the engine-control electronics.

  • Patent number: 5168850
    Abstract: A load adjustment device is provided with a throttle valve (9) which determines the output power of an internal combustion engine and is connected, fixed for rotation, to a throttle-valve shaft (32) which is mounted in the throttle valve housing (30). The throttle-valve shaft (32) has an accelerator-pedal-side, mechanical articulation side and a setting-motor-articulation-side, with which there is associated a coupling element for the mechanical uncoupling of the throttle valve from an electric motor (14), as well as means for reporting the instantaneous position of a throttle-valve lever (21) arranged on the throttle-valve shaft (32) and of a driver element (25) to an electronic control device (17).

  • Patent number: 5161508
    Abstract: A load adjustment device is provided with a throttle valve (9) which determines the output of an internal combustion engine and is fastened, fixed for rotation, to a throttle-valve shaft (32), which is mounted in a throttle-valve housing (30). In idle operation, the throttle-valve shaft (32) is adjusted by an electric motor (14) and a four-link gearing (16) connected behind it. This includes a pinion (14) which is arranged on an output shaft of the electric motor (14) and meshes with a gear segment (50) which is connected for drive via a second link (53) to a rotor (54) which drives the throttle-valve shaft (32). Due to the advantageous arrangement of the four-link gearing (16), a very large transmission ratio can be achieved between the output shaft (40) of the electric motor 14 and the throttle-valve shaft (32), so that a very small, cost-efficient electric motor is sufficient.
