Oil sump arrangement, engine system and vehicle

By introducing a control valve into the oil pan device to control the water inlet according to the oil temperature, the problem of engine power loss and short oil life caused by premature entry of engine oil and coolant is solved. It achieves precise control of coolant at the appropriate temperature, reduces engine power consumption and extends oil life.

AI Technical Summary

Technical Problem

The existing oil pan starts circulating coolant when the oil temperature is low, resulting in slow oil temperature rise, high viscosity, high engine load, serious power loss, and short oil life.

Method used

Design an oil pan device comprising an oil chamber and a water channel. The opening and closing of the water channel inlet is controlled by a control valve according to the oil temperature. Coolant is only allowed to enter the water channel to cool the oil when the oil temperature is suitable. Automatic control is achieved by using an electromagnetic control valve or a paraffin thermostat.

Benefits of technology

It effectively prevents the engine oil from being cooled at low temperatures, reduces engine power consumption loss, extends the service life of the engine oil, and cools it when needed, improving the engine oil cooling efficiency.

Abstract

The utility model relates to an oil pan device, engine system and vehicle, include: oil pan body and control valve, the oil pan body is equipped with the oil cavity and water channel that mutually interval, control valve is connected in oil pan body, and is used for according to the opening and close of the import of water channel control of oil cavity in oil temperature. The oil pan device, engine system and vehicle of this scheme can almost avoid the situation that when the temperature is lower, coolant enters the water channel of oil pan body and cools the oil, and then reach the purpose of reducing the power loss of engine, improving the service life of oil.
