ABSTRACT:
A liquid cooling system for an internal combustion engine charged by a turbosupercharger has forced circulation cooling of the engine and turbosupercharger. To cool the turbosupercharger after the internal combustion engine has been switched off the turbosupercharger inlet pipe contains a check valve and a return flow pipe to an expansion tank is split into branch pipes, a first pipe entering the expansion tank above the cooling liquid level and a second pipe entering the expansion tank below the cooling liquid level and having a check valve. Upon switching off the engine, the cooling liquid in the turbosupercharger is evaporated by residual heat and discharges the cooling liquid into the expansion tank in a cyclic, thrust-like process.
