Abstract
A reductant delivery unit for selective catalytic reduction (SCR) after-treatment for vehicles includes a solenoid operated fluid injector associated with an exhaust gas flow path upstream of a SCR catalytic converter. The fluid injector has a fluid inlet and a fluid outlet. The fluid inlet receiving a source of reducing agent and the fluid outlet communicating with the exhaust gas flow path so that the fluid injector controls injection of urea solution into the exhaust gas flow path. The fluid injector has an inlet tube for directing the reducing agent between the fluid inlet and the fluid outlet. A shield is fixed with respect to the fluid injector and surrounds at least portions of the fluid injector. A coil heater is integral with the fluid injector and is constructed and arranged, when energized, to inductively heat the inlet tube to thereby heat the reducing agent within the inlet tube.
