TURBOCHARGED ENGINE ASSEMBLY WITH TWO EXHAUST DUCTS WITH BURN GAS REINTRODUCTION

摘要

The invention relates to a method for controlling an exhaust of a thermal engine assembly (1) of a motor vehicle comprising an exhaust system housing a turbine (2) of a turbocharger, the exhaust having a first turbine flow from the first passage passing through the turbine (2) housing a wheel for partial recovery of an energy contained in the gases and a second discharge flow from the second passage joining the first flow downstream of the wheel bypassing it. A forced increase in the pressure of the second stream is carried out during the period of common opening for a return of at least part of the second stream in said at least one cylinder for full load conditions under an engine speed of less than 3000 rpm. per minute or partial engine load at an average effective pressure of less than 106 Pascals.
