Warming-up device of internal combustion engine

摘要

A warming-up device of an internal combustion engine includes a latent heat storage material accommodated in the interior of the internal combustion engine and radiating heat based on a phase change, and a nucleation device within the heat storage material and operating to prompt the phase change of the heat storage material under a supercooled state. The nucleation device is operated based on an oscillation generated at a time of starting the engine. As a result, the warming-up device of the internal combustion engine 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 the device is inexpensive and has a simple structure.
