In this case, the receptacles on the driver and passenger sides are configured and arranged such that installation of the loading space covering is possible from a passenger compartment. | 02-26-2009 |
20090049939 | Change Speed Transmission - A transmission, in particular a dual clutch transmission, has a plurality of transmission shafts and a fastening apparatus for at least one fixed gear on one of the transmission shafts. The fixed gear is held axially on the transmission shaft by way of a fastening nut. The fixed gear is formed with a recess around the transmission shaft in a region that lies radially below the gear toothing system. A fastening sleeve is positioned in the recess between the fixed gear and the transmission shaft in a section which adjoins a fastening nut. During the clamping of the fastening nut, the latter bears against the fastening sleeve. As a result, the transmission of micromovements to the fastening nut is minimized or prevented, with the result that loosening of the fastening nut does not take place during the operation of the transmission. | 02-26-2009 |
20090031983 | Air Filter for an Air Intake System of a Multi-Cylinder Internal Combustion Engine - An air filter for an air intake system of a multi-cylinder internal combustion engine has a housing with a first housing part and a second housing part. A filter element is arranged between the housing parts. An untreated air side of the air filter is formed in the first housing part and a clean air side of the air filter is formed in the second housing part. The first housing part has a housing opening for conducting untreated air into the housing and the second housing part has a housing opening for discharging clean air out of the housing. Further, the housing has a third housing opening for conducting untreated air into the housing, with the housing holding a switchable flap arrangement for opening and closing the third housing opening. The flap arrangement can be activated as a function of operating states of the internal combustion engine. This allows variable, in particular large air masses to be passed through an air filter on account of the further housing opening. | 02-05-2009 |
20090025671 | Air Intake System of a Multi-Cylinder Internal Combustion Engine - An air intake system of a multi-cylinder internal combustion engine has a first collecting chamber and a second collecting chamber. An inflow line supplies intake air to the first collecting chamber. First regions of a plurality of ram pipes are connected to the first collecting chamber and guided through the second collecting chamber and opening out into second regions of the ram pipes. The second regions are arranged outside of and connected to the second collecting chamber. The first regions of the ram pipes are arranged within the second collecting chamber and have adjustable sections. When the adjustable sections of the intake pipes are in one position, intake air is sucked in directly through the first and second regions of the ram pipes. When they are in a second position, intake air is sucked into the second collecting chamber and from the latter into the second regions of the ram pipes. An overflow chamber device connects the first collecting chamber and the second collecting chamber to one another. The overflow chamber device forms an additional overflow volume between the two collecting chambers, to provide increased air mass throughput in the power position, that is, in the second position of the adjustable sections of the ram pipes. | 01-29-2009 |
20090020097 | Internal Combustion Engine - An internal combustion engine has a plurality of cylinders and an air intake system. The air intake system is formed from at least one distributor pipe, a plurality of intake pipes, and at least one plenum. The plenum is located between the distributor pipe and the intake pipes. Here, the combustion air is fed to the air intake system via an air guiding duct which opens out into the distributor pipe. The charge pressure of the combustion air is reduced between the outlet out of the compressor and the inlet into the combustion chamber of the internal combustion engine. A distributor pipe length is dimensioned as a function of an equivalent distributor pipe diameter such that it is possible for a reduction in the charge pressure to be obtained within the air intake system by way of an expansion, with the expansion taking place partially in the plenum in the respective intake pipe and/or within the distributor pipe. | 01-22-2009 |
