8.8. System of repeated combustion of exhaust gases (EGR)
Scheme of work of system of repeated combustion of exhaust gases
For reduction of emission of an oxide of nitrogen in the atmosphere together with exhaust gases a part of exhaust gases via the EGR valve comes to an inlet collector and is repeatedly burned.
The system of repeated combustion of exhaust gases consists of the EGR valve, the EGR modulator, the vacuum switching valve (VSV), the block of electronic control (ESM) and the sensor of temperature of the EGR system.
