WARMING-UP DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

A warming-up device of an internal combustion engine is provided with a latent heat storage material (X) accommodated in the interior of the internal combustion engine and radiating heat on the basis of a phase change, and a nucleation device (2) provided within the heat storage material (X) and operating so as to prompt the phase change of the heat storage material (X) under a supercooled state. The nucleation device (2) is operated on the basis of an oscillation generated at a time of starting the engine. As a result, it is possible to provide the warming-up device of the internal combustion engine which dispenses with a machining operation for forming a through port passing through the interior and an outside of the heat storage material, a seal around the through port and an electric circuit, and is inexpensive and has a simple structure.
