Abstract
A water cooled internal combustion engine, especially for utility vehicles operated with a gas which is stored in a liquid condition in a fuel tank. The internal combustion engine includes a cooling water cycle containing a thermostat, a cooler and a water pump. A fuel vaporizer is heated by the cooling water cycle of the internal combustion engine with an air intake preheater likewise being heated by the cooling water cycle. A throttle valve is arranged between the air/gas mixer and working cylinders of the engine. An externally heated water cycle is additionally provided in such a way that the externally heated water cycle is connected functionally in parallel with the cooling water cycle. The water cycles are joined by a conduit with a thermostatic valve being arranged within the conduit so that the two cycles can be switched in such a manner than, in dependence upon the temperature, water from the externally heated water cycle and/or from the cooling water cycle is conducted through the fuel vaporizer and intake air preheater. The externally heated water cycle, when the internal combustion engine is not yet warmed up for operation, and the cooling water cycle, when the internal combustion engine is warmed up for operation, are switched on with respective priority.
