Die vorliegende Erfindung betrifft ein Verfahren zum Betreiben eines getaktet angetriebenen Kolbenmotors, der mindestens einen Zylinder, mindestens einen im Bereich eines Zylinderkopfs angeordnetes Einlassventil und mindestens einen im Bereich des Zylinder...

An exhaust gas emission control system for a diesel engine, having an oxidation catalyst (DOC) (7) and a diesel particulate filter (DPF) (9) in an exhaust passage, wherein a late post-injection control unit (62), which injects fuel into a combustion chambe...

Provided is an engine exhaust-gas purification device which can meet exhaust gas regulations by addressing the ship itself, even when using conventional fuel rather than low sulphur fuel. An engine exhaust-gas purification device (1) which reduces and remo...

Provided is a hydraulic drive system for a hydraulic working machine, which can surely set a delivery pressure at a preset value upon raising a temperature of exhaust gas to a temperature needed for combustion of particulate matter by increasing a load to ...

In an internal combustion engine utilizing an exhaust gas recirculation, an exhaust gas recirculation rate is set to a minimum or zero at a small engine load. The exhaust gas recirculation is carried out after lowering an exhaust gas temperature by a heat ...

An exhaust emission control system of an internal combustion engine capable of post injection is disclosed which provides control such that the injection timing in sub injection is set to a point earlier than the target injection timing when the sub inject...

An exhaust emission control system of an internal combustion engine is provided which controls the oxygen concentration of exhaust passing through the exhaust emission control device (2) according to the flow rate of exhaust flowing through an exhaust pass...
