Claims

[Claims for Utility Model Registration] 1. A main circulation oil passage and an auxiliary circulation oil passage are provided as oil passages for pumping engine oil to parts that require cooling to cool the cooling part, and the main circulation oil passage is equipped with a main oil pump that is activated by engine operation, and an auxiliary oil pump is provided in the auxiliary circulation oil path, and the auxiliary oil pump is equipped with an auxiliary oil pump that is activated when the cooling part is at a predetermined temperature or higher after the engine has stopped. An engine oil circulation device for an engine, comprising a power supply circuit that supplies a driving current to an oil pump. 2. The power supply circuit according to claim 1 of the utility model registration claim includes a thermoelectric generating element in the cooling section or the exhaust pipe section,
An engine oil circulation device in an engine configured to drive an auxiliary oil pump by thermoelectromotive force of the thermoelectric generating element. 3. The power supply circuit according to claim 1 of the utility model registration claim is wired to drive an auxiliary oil pump using a vehicle-mounted battery as a power source, and a switch that is turned on when the engine switch is turned off is installed during the wiring. An engine oil circulation system for an engine that includes a switch that is turned on when the temperature of the cooling section is higher than a predetermined temperature.
