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.
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.
Abstract:
A load adjustment device is provided having a throttle valve which determines the output of an internal combustion engine and is connected, fixed for rotation, to a throttle-valve shaft (32) which is mounted in a throttle-valve-shaft housing (30). The shaft has an acceleration-pedal side mechanical articulation side (33) and a setting-motor articulation side (34) with which there is associated a coupling element (45) for the mechanical uncoupling of the throttle-valve shaft from the setting motor within a defined angular region of the throttle valve; furthermore, a device is provided for reporting the instantaneous position of the coupling element to an electronic control device. In order, in the case of such a two-sided control of the throttle valve, to permit a structurally simple report of the position of the electric setting motor to the accelerator-pedal-side articulation side, the throttle-valve shaft is developed as a tube and the reporting device has a pass-through shaft (48) which passes through the throttle-valve shaft, a first transmission member (49) which is connected, fixed for rotation, with the pass-through shaft and the coupling element on the setting-motor articulation side and, on the accelerator-pedal-side articulation side, a second transfer member (50) which is connected, fixed for rotation, with the pass-through shaft and which cooperates with an actual-value detection device (18) associated with the control device.
