Abstract: A cooling device for an internal combustion engine of a motor vehicle, particularly of a passenger car, has at least one radiator, through which cooling water is flowing. The radiator is disposed in a cooling cycle and connected over a supplying pipeline and a returning pipeline with the internal combustion engine. Moreover, a heat exchanger, with which the oil of a transmission is cooled, is provided in the cooling cycle. For spatial and functional reasons, a flow resistance is connected in the supplying pipeline before the internal combustion engine. A branching pipeline, which is connected with the heat exchanger of the transmission and downstream, behind the heat exchanger, with the flow resistance, leads away from the supplying pipeline.

Abstract: A helicopter is driven by means of a rotor that is connected with an internal-combustion engine. The air-cooled internal-combustion engine has a horizontally opposed construction and is arranged within walls of a cabin of the helicopter. In order to supply the internal-combustion engine with cooling air and intake air, air inlet openings are provided at the side walls of the cabin. For the discharge of the cooling air, outlet openings are arranged at the underside of the cabin.

Abstract: An air supply channel for a charging air intercooler of an exhaust gas turbocharger of an internal combustion engine arranged in the rear of a vehicle, in which the air supply channel is arranged within the fender area of the vehicle and includes an air inlet and an air discharge opening; the channel includes a tubular element which is constructed trumpet-shaped and is retained in the wheel casing above the rear wheel; at its air inlet side, the channel is connected with an inlet connection fixed at the body by way of a connecting sleeve and at its air discharge side with the charging air intercooler.
