An oil supply system for an internal combustion engine includes an oil pump, a heat exchanger, an oil feed line and two oil outlet lines, for conveying the oil from the oil pump through the oil feed line to the heat exchanger and from the latter through the two oil outlet lines. In a system of this type, there is provision for the internal combustion engine to be configured as a piston engine and for the heat exchanger to be configured as a water/oil heat exchanger, and for one oil outlet line to be connected to oil spray nozzles of the piston engine and for the other oil outlet line to be connected to a main oil line of the piston engine. An oil supply system of this type is distinguished by its simple design and functionality, and permits optimum cooling and lubrication of the relevant components of the engine.

1. An oil supply system for an internal combustion engine, having an oil pump, a heat exchanger, an oil feed line, a first oil outlet line and a second oil outlet line, for conveying the oil from the oil pump through the oil feed line to the heat exchanger and from the heat exchanger through the two oil outlet lines, wherein the internal combustion engine is configured as a piston engine and the heat exchanger is configured as a water/oil heat exchanger, and the first oil outlet line is connected to oil spray nozzles of the piston engine and the second oil outlet line is connected to a main oil line of the piston engine, wherein an oil filter is arranged downstream of the oil pump, between the oil pump and the heat exchanger. 2. The oil supply system as claimed in claim 1, wherein, downstream of the oil pump, an auxiliary oil feed line connects the oil feed line to the second oil outlet line from the heat exchanger to the main oil line. 3. The oil supply system as claimed in claim 2, wherein a thermostat is provided for controlling the oil throughflow through the oil feed line to the heat exchanger and through the auxiliary oil feed line. 4. The oil supply system as claimed in claim 1, wherein the first oil outlet line is configured to be fluidly disconnected from the oil spray nozzles by a valve. 5. The oil supply system as claimed in claim 1, wherein two oil spray nozzles, which are configured to be switched in a manner controlled by characteristic diagram, are provided per cylinder of the piston engine. 6. The oil supply system as claimed in claim 1, wherein the two outlets from the heat exchanger, which are assigned to the oil outlet lines, are arranged in different regions of the heat exchanger, wherein a greater proportion of colder oil enters into the first oil outlet line to the oil spray nozzles than enters into the second oil outlet line to the main oil line. 7. The oil supply system as claimed in claim 1, wherein a measuring device is provided for detecting a temperature and a pressure of the oil in the second oil outlet line and/or the main oil line. 8. The oil supply system as claimed in claim 1, wherein the piston engine has dry sump lubrication. 9. The oil supply system as claimed in claim 8, wherein the oil is conveyed from the dry sump via suction stages to an oil tank, and the oil tank is connected to the oil pump via a connecting line. 10. The oil supply system as claimed in claim 1, wherein the piston engine is a boxer engine.
