Embodiment Construction

[0041] figure 1 A schematic diagram of an internal combustion engine 1 with an exhaust gas turbocharger 10 and a device V according to the invention for exhaust gas recirculation is shown.

[0042] In this embodiment, the internal combustion engine 1 is a diesel engine with six cylinders 2 , an intake line 3 and an exhaust line 4 . The exhaust gas turbocharger 10 has an exhaust gas turbine 11a which is coupled via a shaft 11b to a compressor 11c. The intake line 3 is connected to the compressor 11 c of the exhaust gas turbocharger 10 via a gas supply device 14 . In this case, a charge air cooler 13 is arranged between the gas delivery device 14 and the compressor 11 c. The compressor 11c of the exhaust gas turbocharger 10 is connected to the air intake 5 for the fresh gas FG. The term fresh air here also refers to fresh air from the atmosphere. An air filter (not shown in the figure) can also be inserted in this line.

Abstract

The device (V) has an exhaust gas recirculation unit (AGR) with a recirculation valve (8) which is connected with an exhaust gas line (4) and a suction line (3) of an internal combustion engine (1) to be associated. An air compressor (20) is provided for the compression of retrived exhaust gas and is connected with the exhaust gas line. An exhaust gas-pressure container (28) is formed for storing the compressed exhaust gas and is connected with the air compressor. An independent claim is included for a method for recirculating the exhaust gas of an internal combustion engine, particularly a diesel engine.

Description

technical field [0001] The invention relates to a device and a method for recirculating exhaust gases of an internal combustion engine, in particular a diesel engine, having an exhaust gas turbocharger. The invention also relates to an internal combustion engine. Background technique [0002] The use of internal combustion engines or internal combustion engines is governed worldwide by correspondingly applicable exhaust gas legislation. This includes consideration of nitrogen oxides, particulates, carbon monoxide and incompletely burned hydrocarbons. First, efforts to reduce are focused on particulate and nitrogen emissions. For example from 2013 / 14 the European legislator limits particulate and nitrogen emissions from heavy goods vehicles to 0.4g / kWh nitrogen oxide and 0.01g / kWh particulate, see European Parliament and Senate of 18 June 2009 no. Regulation (EG) 595 / 2009. [0003] Nitrogen oxides are produced in three different ways during the combustion process in inter...
