internal combustion engine piston to more cylinders with at least duebanchi cylinders.

摘要

In a multi-cylinder internal combustion engine having at least two cylinder banks each with an exhaust system including a catalytic converter, wherein one of the cylinder banks can be deactivated when the engine operates only under partial load, the exhaust systems have exhaust pipe sections which are interconnected by a cross-over structure disposed upstream of the catalytic converters so that exhaust gas can flow also through the catalytic converter of the deactivated cylinder bank, and a length compensating element is disposed in at least one of the exhaust pipe sections and the cross-over structure.
