Abstract

An IC engine with cooling system (2,4,5,7) and lubricating system (17,19,22) has a control unit (51). A thermal insulated accumulator tank (14) with pressure container (34) for storing heated engine oil which is fed from the coolant pump (2) via a valve (7,10). A drain pump (28) transfers all the oil from the oil sump to the pressure container. On re-starting oil is directed straight into the engine lubricating passages (22) via a valve (36) and cold coolant is replaced from the accumulator tank via a valve (10). The exhaust (40) is looped via a valve (47) to heat oil in the engine oil sump.

Description

10 15 20 506 244 2 Figurerna visar en termiskt isolerande vakuumzon l mellan en yta 2 och en motstående yta 3 samt flera mellanliggande strålningsbarriärer 4. Strålningsbarriärerna 4 har utbukt- ningar 5 fördelade över ytorna. Utbuktningarna 5 kan vara utformade på olika sätt, exempelvis som rätlinjiga eller kroklinjiga åsar, konor, halvsfärer eller liknande, vilket ger en begränsad kontaktyta 6. Utbuktningarna 5 kan vara utförda i grundmaterialet eller av tillsatsmaterial. Utbukt- ningarna 5 är försedda med hål 7. 10 15 20 506 244 2 The figures show a thermally insulating vacuum zone 1 between one surface 2 and an opposite surface 3 and several intermediate ones radiation barriers 4. The radiation barriers 4 have bulges 5 distributed over the surfaces. The bulges 5 may be designed in different ways, for example as rectilinear or curvilinear ridges, cones, hemispheres or the like, which gives a limited contact surface 6. The bulges 5 can be made of the basic material or of additive material. Bulging the holes 5 are provided with holes 7.

När det finns en temperaturdifferens mellan ytorna 2,3 strå- lar värmeenergi från den varmare ytan till den kallare.When there is a temperature difference between the surfaces 2,3 converts heat energy from the warmer surface to the colder one.

Strålningsbarriärerna 4 reducerar denna värmestrålning. I och med att strålningsbarriärerna 4, exempelvis tillverkade av blank aluminiumfolie, förses med utbuktningar 5, fungerar dessa som distanser. Detta gör det möjligt att ha barriärerna placerade sida vid sida och samtidigt erhålla en spalt mellan dessa. De förluster, som på grund av ledning uppstår vid kontaktytorna 6 mellan utbuktningarna 5 och närmast intill- iggande barriär 4, är i det närmaste försumbara. Genom ut- buktningarnas hål 7 erhålls evakueringsvägar för den gas som skall pumpas ut ur zonen 1 i samband med dess tillverkning.The radiation barriers 4 reduce this heat radiation. In and with the radiation barriers 4, for example made of glossy aluminum foil, provided with bulges 5, works these as distances. This makes it possible to have the barriers placed side by side and at the same time obtain a gap between these. The losses that occur due to management the contact surfaces 6 between the bulges 5 and the nearest barrier 4, is almost negligible. By hole 7 of the bends, evacuation paths are obtained for the gas which shall be pumped out of zone 1 in connection with its manufacture.
