Title:
内燃機関の排ガス系に向かう燃料を調量するための装置
Document Type and Number:
Japanese Patent JP2010514974
Kind Code:
A
Abstract:
The device (10) has an injection valve (14) arranged in an exhaust gas system (12) and cooled in a closed condition by a flowing coolant, where the valve is supplied with a fuel via a fuel inlet (16). The inlet is fed from a low pressure system (18) of an injection system, which serves for dosage of the fuel for combustion that takes place in a combustion chamber of an internal combustion engine. A hydraulic damping device (20) is provided for damping pressure oscillation, is connected with the fuel inlet and exhibits a damping volume that is attached to a fuel-accumulative-return valve (32).
