A system for pre-start heat preparation of power unit of transportation device includes heat accumulator (HA) in which heat accumulating substance with phase transition is used, this is placed in annular space, has channels of HA are connected in parallel to discharge system of engine, liquid channels – in parallel to cooling system of engine, valves and pump unit that pumps through cooling liquid. Additional heat accumulator (AHA) for cooling liquid is used, its body is formed with double walls with air gap. At that in AHA removable capsule with heat accumulating liquid is placed, with pipeline for worked-out gases connected to discharge system of the engine. |
