EGR valves (Exhaust Gas Recirculation) are present in all of today’s diesel engines and in a growing number of petrol engines as well. Designed to reduce harmful emissions and help protect the engine, NTK EGR valves are rigorously tested to meet the highest standards.
100% of diesel engines in Europe are fitted with an EGR valve

Nitrogen oxides (NOx) are produced during the combustion process. NOx is created when high combustion temperatures enable the nitrogen and oxygen present in the air-fuel mixture to combine. To reduce these harmful emissions the EGR valve takes exhaust gases from the exhaust manifold and reintroduces them into the intake manifold, mixing them with fresh air. This has a double effect, reducing the amount of oxygen in the air-fuel mixture and reducing the temperature, and thereby reducing the amount of NOx the engine produces.
