The invention relates to an internal combustion engine having a piston-cooling arrangement () which has at least one spray device () which is supplied with a coolant/lubricant via at least one supply passageway (). The supply passageway () is arranged in a module () composed of a crankshaft-bearing structural element () and a crankshaft-bearing cap (). The spray device () is coupled to the crankshaft-bearing cap (), a crankshaft-bearing shell () in the region of the supply passageway (). Supply passageway () also connect to through-opening (), so that coolant/lubricant can be directed via the supply passageway () to both the spray device () and a crankshaft (). The spray device () is designed as an oil-spray nozzle () or alternatively as a spray hole () integrated in the crankshaft-bearing cap ().
