An internal combustion engine has a plurality of cylinders which are arranged in two rows, two exhaust-gas turbochargers which are driven in each case by the exhaust gases from the cylinders of a cylinder row, and exhaust-gas recirculation. Two exhaust-gas discharge lines branch off, upstream of the respective exhaust-gas turbocharger, part of the exhaust gases from the cylinders of a cylinder row to be recirculated and supply this part to a common recirculation line. By way of the common recirculation line, the exhaust gases to be recirculated are supplied, downstream of the exhaust-gas turbochargers, to an air supply. At least one valve, which serves as an exhaust-gas recirculation valve and by which the quantity of recirculated exhaust gases can be set, is provided. The valve has a stop by which a communicating connection made between the two exhaust-gas discharge lines can be shut off.

A regulation apparatus for determining the flow of fluid to a hyraulically-operated cooling fan of an air-cooled internal combustion engine includes an electromagnetic valve connected in the fluid line to the cooling fan, a control unit which sends a signal to the electromagnetic valve to control its operation, and multiple sensor elements which are positioned in or near the engine to detect the various parameters which affect its operation, the sensor elements sending electrical input signals to the control unit.
