Abstract

An internal combustion engine, especially a diesel engine, with at least one combustion chamber, an intake system having at least one intake manifold, an exhaust system having at least one common exhaust line, and an exhaust gas recirculation system for reintroducing exhaust gas into the intake system, the exhaust gas recirculation system including at least one exhaust gas recirculation line with an exhaust gas recirculation valve the exhaust gas recirculation line branching off directly from the combustion chamber, the EGR valve being positioned preferably at the branch-off, in order to reduce Nox emissions and ensure good fuel economy.
