Abstract
An evaporation-cooled internal combustion engine having a cooling system that can be pressurized and that includes a surge tank and a radiator. The surge tank (1) communicates through a line (2) with a section of the cooling system (3) that is constantly full of liquid coolant while the engine is in operation. The engine operation is thereby unaffected by low ambient temperatures.
Claims15
In an evaporation-cooled internal combustion engine having a pressurizable cooling system including a surge tank and a radiator, the improvement wherein the surge tank communicates through a line with a section of the cooling system that is constantly full of liquid coolant while the engine is in operation;
- wherein the cooling system includes at least one condensation radiator;
- and wherein a convection radiator parallels the condensation radiator.
In an evaporation-cooled internal combustion engine having a pressurizable cooling system including a surge tank and a radiator, the improvement wherein the surge tank communicates through a line with a section of the cooling system that is constantly full of liquid coolant while the engine is in operation;
- wherein the cooling system further includes a coolant-intake line and a coolant-outlet line and wherein the cooling system is completely full of liquid coolant during vapor-free operation.
In an evaporation-cooled internal combustion engine having a pressurizable cooling system including a surge tank and a radiator, the improvement wherein the surge tank communicates through a line with a section of the cooling system that is constantly full of liquid coolant while the engine is in operation;
- and wherein the surge tank comprises a partition formed of a piston arranged to move within a cylinder.
