Particle sensor for protection of components of exhaust system of turbocharged engine, is arranged at lower pressure side of turbocharger, and outputs signal for switching off exhaust gas recirculation

摘要

The particle sensor (17) is arranged at a lower pressure side of a turbocharger (5). The particle sensor outputs a signal for switching off an exhaust gas recirculation (14) when a particle concentration is exceeded. Independent claims are also included for the following: (1) an exhaust system for a turbocharged engine; and (2) a method for protection of components of an exhaust system of a turbocharged engine.
