Internal combustion engine with cooling system

摘要

A piston internal combustion engine with at least one cylinder and with a cooling system coordinated thereto that operates with a fluid medium and includes an oil-spray cooling system; at partial engine loads, the cooling output is reduced by disconnection of a part of the oil-spray cooling system so that the heat content in the combustion space increases while the specific fuel consumption is reduced and the warm-up period of the engine after the start is reduced.
