Patent number: 6138648Abstract: 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.Type: GrantFiled: April 16, 1999Date of Patent: October 31, 2000Assignee: Mannesmann VDO AGInventor: Matthias Zentgraf

Patent number: 5713322Abstract: 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.Type: GrantFiled: August 18, 1995Date of Patent: February 3, 1998Assignee: VDO Adolf Schindling AGInventors: Eberhard Mausner, Reiner Weingartner, Manfred Pfalzgraf, Matthias Zentgraf

Patent number: 5168850Abstract: 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).Type: GrantFiled: April 19, 1991Date of Patent: December 8, 1992Assignee: VDO Adolf Schindling AGInventors: Matthias Zentgraf, Gerd Hickmann

Patent number: 5161508Abstract: 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.Type: GrantFiled: April 19, 1991Date of Patent: November 10, 1992Assignee: VDO Adolf Schindling AGInventors: Matthias Zentgraf, Gerd Hickmann, Peter Volz
