The present disclosure provides a split cooling apparatus for an internal combustion engine, the apparatus including: a base inserted into a water jacket of a cylinder block, the base surrounding an outside of a cylinder along a shape of the cylinder; an insertion groove formed on the base by being depressed into an inner surface of the base; and a sealing member inserted into the insertion groove, wherein when a temperature of cooling water supplied into the water jacket reaches a preset temperature or higher, the sealing member expands so as to close a flow passage between the base and the cylinder, thereby increasing flow resistance of the cooling water and thus reducing a heat transfer rate of the cylinder.

The supercharging system and the internal combustion engine according to the present invention are provided with: a first supercharger (20); a second supercharger (30); an electric motor (23) connected to a shaft end of a first compressor (21); a generator (24) connected to a shaft end of a first turbine (22); a bypass exhaust pipe (L6) that allows exhaust air to bypass the first turbine (22); a cooler (51) that cools the generator (24); and a control device (50) that activates the cooler (51) when the generator (24) is driven by exhaust air that has driven the first turbine (22).

An engine temperature control system is provided for heating and/or cooling engine fluids to resist deviation of the temperature of these fluids from a temperature range wherein optimal fluid performance is achieved. Some examples of the temperature control system provide for preheating fluids such as coolant, lubricant, or diesel exhaust fluid prior to starting the engine. Other examples of the temperature control system provide for improved cooling of lubricants utilized for high heat generating components such as turbochargers, continuing cooling of these fluids after the engine is stopped.

In a method for cooling a component of a motor vehicle, which component is coupled thermally to a cooling volume filled with a liquid coolant, at least one cooling parameter is measured by a control device and, in dependence on the cooling parameter, the component is either cooled in a first cooling mode, in which the cooling volume is connected via a first and second coupling device to a cooling circuit which includes at least one circulating device by means of which the coolant is circulated, or is cooled in a second cooling mode, in which the cooling volume is separated from the cooling circuit by the first and second coupling device, wherein the component is cooled by evaporation of coolant in the cooling volume.

A power generation system is provided that includes an internal combustion engine configured to provide rotational mechanical energy. A generator is configured to receive the rotational mechanical energy and generate electrical power in response to the rotational mechanical energy. A fluid medium is provided to the internal combustion engine and to the generator for removing thermal energy from the internal combustion engine and from the generator.
