EATS for converting NOx emissions in exhaust gases from an engine

An exhaust aftertreatment system, EATS, for converting NOx emissions in exhaust gases from an engine, the EATS comprising:

• a fluid channel for providing a fluid pathway for the exhaust gases,
• a selective catalytic reduction, SCR, catalyst arranged in the fluid channel, the SCR catalyst being configured to store ammonia,
• an injector configured to inject a reductant for providing ammonia to the SCR catalyst, the injector being arranged upstream of the SCR catalyst,
• a fluid flow inducer configured to cause an induced fluid flow in at least a part of the fluid channel when the engine is turned off,
• a controlling apparatus configured to precondition the EATS prior to engine start by injecting the reductant into the fluid channel, and transport the reductant into the SCR catalyst by the induced fluid flow to store ammonia in the SCR catalyst, the EATS further comprising an electrical heating arrangement for heating the reductant, the controlling apparatus being configured to heat the reductant by the electrical heating arrangement, wherein the electrical heating arrangement is arranged in the fluid channel upstream the injector with no other EATS components in between.
