Abstract: To provide an exhaust emission control device of an internal combustion engine able to well atomize a reducing agent and ensure supply of combustion air. Since a controller of the exhaust emission control device also controls a nozzle opening degree of a variable geometry turbocharger for purpose of spraying a urea water, even in the state where the engine works in a low load range of T1 to T2 where supercharging pressure normally can not be increased, supercharging pressure P suitable to atomization of the urea water can be obtained by controlling the nozzle opening degree of the variable geometry turbocharger to be closer to a closing side compared to the conventional art (shown by the chain double-dashed line), while the urea water can be securely atomized by a part of the supercharged air.

Abstract: A reciprocating engine includes a turbocharging unit that: supplies the intake manifold with air via a coolant; is supplied with gas by the exhaust manifold; and has the turbine supply pressure substantially equal to the compressor discharge pressure. At constant air temperature, the turbocharging unit delivers a substantially constant volume of cooled air when the pressure varies, and the volume is substantially proportional to the turbine outlet section. The turbine pressure is maintained substantially equal to compressor pressure by a EGR bypass between the intake and exhaust manifold. In addition, the volume of air is less than the volume drawn in at the speed so that a flow of hot gases is drawn in again via the bypass above the speed, where the volume drawn in is equal to the volume, and a flow of air is deflected towards the turbine below the speed.
