SCR module

Abstract

Reciprocating-piston internal combustion engines having different power outputs are to be equipped simply, reliably and inexpensively with a device for the selective catalytic reduction of the exhaust gases having an SCR module for a reciprocating-piston internal combustion engine, comprising a housing and / or a frame, an exhaust-gas section which delimits a flow duct for guiding through exhaust gas, having an inlet opening for introducing the exhaust gas and an outlet opening for discharging the exhaust gas, an SCR catalytic converter which is arranged inside the flow duct, at least one injection element for adding a reducing agent, for example ammonia or a urea solution, to the exhaust gas which is guided through the flow duct. This problem is solved by virtue of the fact that the SCR module comprises at least one delivery device (13) for feeding the reducing agent to the injection element at a predetermined pressure.

Description

technical field [0001] The invention relates to an SCR module according to the preamble of claim 1 , an internal combustion engine system according to the preamble of claim 6 and a method for producing a method for an internal combustion engine system. Background technique [0002] Reciprocating piston internal combustion engines are used in different applications. In stationary installations, a reciprocating internal combustion engine is combined with a generator, for example to generate electricity. In mobile installations, reciprocating piston internal combustion engines are used to drive ships, military vehicles such as armored vehicles or also agricultural vehicles. In this case, the reciprocating internal combustion engine should have the lowest possible nitrogen oxide emissions. It is known to selectively reduce nitrogen oxides in the exhaust gas at the SCR catalyst by means of selective catalytic reduction (SCR). As a result, nitrogen oxide (NOx) emissions can be...

AI Technical Summary

Problems solved by technology

For this reason, it is necessary to provide correspondingly different devices for reciprocating piston internal combustion engines with different powers in a costly and expensive manner

This significantly increases the costs for producing the internal combustion engine system and, moreover, expensive, expensive and error-prone assembly outlays occur during the production of the internal combustion engine system
