Fuel dosing device for exhaust gas system of internal combustion engine i.e. diesel engine, has damping device provided for damping pressure oscillation and connected with fuel inlet that is fed from low pressure system of injection system |
摘要 |
<p>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).</p> |
