According to one aspect of the present invention, a liquid reductant tank for supplying liquid reductant to a selective catalytic reduction system is disclosed. The tank includes a tank cavity for holding a liquid reductant and being at least partially defined by one or more side walls; a liquid reductant supply line at least partially situated within the tank cavity and for communicating liquid reductant from the tank cavity to outside of the tank cavity; and a heating element situated at least partially within the liquid reductant supply line and for thawing frozen reductant situated within the supply line during cold start conditions to obtain liquid reductant for use in a selective catalytic reduction system.

Method and apparatus for rapidly thawing frozen NOx reductant

Systems and methods are provided for injecting liquid reductant into an engine exhaust. An example system includes a gas deflector positioned upstream of an injector where the gas deflector is configured to create a high pressure zone upstream of the deflector and a low pressure zone downstream of the deflector surrounding the injector outlet. A bypass flow passage diverts exhaust flow from the high pressure zone upstream of the deflector to allow the bypassed portion of exhaust to flow into the exhaust gas stream to form a gas shield for a liquid reductant spray from the injector. In this way, it is possible to reduce deposit formation and accumulation in the exhaust system.

Bypass purge for protecting against formation of reductant deposits

An exhaust system for an internal combustion engine for a vehicle is provided. The system comprises an exhaust passage with an angled injector and a plurality of mixing devices.
