HEAT ACCUMULATOR FOR MAINTAINING START-UP TEMPERATURE OF ICE DURING INTER-SHIFT DOWNTIME OF CONSTRUCTION MACHINE DURING WINTER SEASON Russian patent published in 2011 - IPC F02N19/00 

FIELD: engines and pumps.

SUBSTANCE: invention refers to devices for heating and maintenance of start-up temperature of internal combustion engine (ICE). Heat accumulator for maintaining the start-up temperature of ICE of construction machine during inter-shift downtime represents the cover fixed on jacket and tray of the engine. Cover consists of the first, the second and the third layers. The first layer represents material from strong reinforcing grid of polyester fibres with fixed cells, and layer of plasticised polyvinylchloride. The second layer is made on the basis of foamed polyethylene coated with aluminium foil. The third layer represents separate sections filled with phase-transition heat-accumulating material; at that, the above sections are located in three rows so that the first and the second row is located along ICE jacket with left and right side, and the third row of sections is located along oil pan of ICE. Sections with heat-accumulating material are attached to the second layer in order to exclude the possibility of movement of sections during ICE operation.

EFFECT: effective maintenance of start-up temperature of internal combustion engine during inter-shift downtime of construction machine.
