SYSTEM AND METHOD OF HEATING OF URGENT INJECTION SYSTEMS (VERSIONS) Russian patent published in 2017 - IPC F01N3/20 

FIELD: engines and pumps.

SUBSTANCE: reductant supply system is designed to supply the reducing agent to the exhaust aftertreatment system of the engine heated during cold temperature conditions. Heat transfer agent flows through the heat path, which ensures a flow path from the heat source to the feeder, water flows out of the tank for the storage of the reductant and the storage tank of the reductant to heat source. Control valve regulates the flow of the heat transfer agent in the heat transfer circuit, so that at least one heat cycle provides circulation period, which exceeded low reducing agent in detergent compartment and storage tank, and the period ending where circulation stops until it reaches the lower limit temperature reducer in the feeder.

EFFECT: increase of economy and ecological compatibility.
