Diesel internal combustion engine operating method involves feeding air, filtered by air filter, through intake section of internal combustion engine and conducting secondary air over secondary compressor in exhaust gas tract

摘要

The method involves feeding the air, filtered by an air filter (15), through an intake section and conducting the secondary air over a secondary air compressor (27) in the exhaust gas tract. Diesel internal combustion engine (10) has pipelines for secondary air, which has extraction tube for secondary air to be taken from induction tract or the atmosphere. The excess pressure of the pressurized air source is used to drive a secondary air turbine (26) of the secondary air system (22) and the secondary air turbine (26) drives the secondary air compressor. An independent claim is also included for a diesel internal-combustion engine has an air intake system for the combustion air with an intake air filter.
