Abstract
In an internal combustion engine of a motor vehicle, in order to shorten the cold-starting phase, it is provided that upon a shut off of the engine, essentially the entire amount of coolant is pumped out of a cooling system into a normally empty heat insulated reservoir, from which the coolant is fed back into the cooling system again upon subsequent start up of the engine.
Claims19
A method of moderating the temperature of an internal combustion engine of a motor vehicle during start up of the engine after the engine had previously been shut off, using a cooling system that circulates liquid coolant through the engine, and a normally empty heat-insulted reservoir, said method comprising feeding the liquid coolant from the cooling system to the reservoir upon shut off of the engine, upon subsequent start up of the engine feeding the coolant from the reservoir to the cooling system.
In a cooling system for an internal combustion engine of a motor vehicle having a cooling system conduit through which liquid coolant is circulated between a radiator and the engine, a reservoir system comprising a normally empty heat-insulating reservoir, a reservoir conduit connecting said cooling system conduit with said reservoir, a pump in said reservoir conduit operable upon shut off of the engine to feed the liquid coolant from said cooling system into said reservoir, and a valve in said reservoir conduit operable upon start up of said engine for feed of the liquid coolant from said reservoir into said cooling system.
