Title:
排気ガスターボチャージャを有する内燃機関の動作方法及びその装置
Document Type and Number:
Japanese Patent JP2007529670
Kind Code:
A
Abstract:
in a method for operating a supercharged internal combustion engine and an internal combustion engine including an exhaust gas treatment system which comprises a catalytic converter arranged close to the engine, an exhaust gas turbocharger which is arranged downstream of the catalytic converter, and a post-injection device for introducing additional fuel into the exhaust gas flow upstream of the catalytic converter, wherein the heat energy of the exhaust gas mass flow which acts on the exhaust gas turbocharger is varied by controlling the fuel quantity which is additionally introduced into the exhaust gas flow by means of the post-injection device resulting in an improvement in the response behavior of the internal combustion engine, excess energy which is generated by the exhaust gas turbocharger by means of a motor generator connected to the exhaust gas turbocharger is stored in a storage device and is returned to the motor generator for rapidly accelerating the turbocharger when an increased power output is demanded from the engine.
