Patent number: 10641163Abstract: A supercharged internal combustion engine has cylinder groups with plural cylinders and plural exhaust gas turbochargers. Exhaust gas can be fed to at least one first exhaust gas turbocharger from first outlet valves of the cylinders of the first and second cylinder groups via at least one first exhaust manifold. Exhaust gas can be fed to at least one second exhaust gas turbocharger from second outlet valves of cylinders of the first and second cylinder groups via a second exhaust manifold. At low rotational speeds and/or in part load and/or non-steady state operation, exhaust gas can be fed via the first exhaust manifolds that are connected to the first outlet valves per cylinder group to a turbine of the first exhaust gas turbocharger in flows that can be divided in the inflow region of the turbine, while the second exhaust gas turbocharger is inactive.Type: GrantFiled: March 29, 2017Date of Patent: May 5, 2020Assignee: Dr. Ing. h.c.

Publication number: 20090031983Abstract: 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.Type: ApplicationFiled: July 24, 2008Publication date: February 5, 2009Applicant: Dr. Ing. h.c.

Publication number: 20090025671Abstract: 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.Type: ApplicationFiled: July 24, 2008Publication date: January 29, 2009Applicant: DR.
