Abstract

An embodiment of the abovementioned invention is shown in the drawing and is described with reference to this in the following abstract. The drawing shows: insulated tank, water pump electrically driven by the vehicle mains, time switch (adjustable electrical time-lag relay) with push-button operation and function pilot lamp, pressure valve with circulation bore, feed line from the engine, return line to the engine, non-return valve to the feed line, non-return valve to the return line, non-return valve to the connecting line, remote thermometer of the insulated tank. The operating principle of the invention shown lies in the fact that the quantity of cooling water in the insulated tank during operation is circulated by way of the circulation bore of the pressure valve (4) and thereby gradually raised to operating temperature. The amount of heat which is thereby stored in the contents of the tank is available for the next starting for warming up the engine (approx 16 to 20 hours, depending on the type of insulation). By pressing the start button of the electrical timer switch (3) the circulating pump driven by the vehicle mains is put into operation until such time as the hot cooling water of the insulated tank has been replaced by the cold cooling water of the engine; a function display is provided by the pilot lamp at (3). The main purpose of the invention is thereby achieved: that is to preheat the engine without an external energy supply before the starter has been operated. <IMAGE>
