https://en.wikipedia.org/wiki/Exhaust_gas_recirculation In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders.
just googling, but, EGR suppose not control air intake?
