Reduced Nox emissions by Exhaust Gas Recirculation
The Exhaust Gas Recirculation (EGR) system partially cools the exhaust gas, and by mixing it with suction air and circulating it within the cylinder, lower the burning temperature inside the cylinder and decrease nitric oxide (NNOX). The EGR valve controls the circulating mount of EGR depending on the density of intake oxygen, which in turn depends on the suction temperature and altitude. It allows a stable combustion control of fuel under all working conditions.
