Supercharged internal combustion engine with separate exhaust manifolds and method to operate such an engine

The engine (1) e.g. four-cylinder in-line engine, has a cylinder (3) including switched outlet openings (4a, 4b) for discharging exhaust gas. Exhaust pipes (5a, 5b) of the switched outlet openings are connected to total exhaust pipes (7a, 7b) within a cylinder head (2) by the cylinder under formatio...

More Information
Summary:The engine (1) e.g. four-cylinder in-line engine, has a cylinder (3) including switched outlet openings (4a, 4b) for discharging exhaust gas. Exhaust pipes (5a, 5b) of the switched outlet openings are connected to total exhaust pipes (7a, 7b) within a cylinder head (2) by the cylinder under formation of exhaust manifolds (6a, 6b). The total exhaust pipes are connected with turbines (8a, 9a) of outlet openings (8, 9), where the turbines are equipped with bypass pipes (10a, 10b) that branch from the exhaust manifolds upstream of the turbines to be directed over turbine housing. An independent claim is also included for a method for operating a turbocharged internal combustion engine.
