Beschreibung
Zusammenfassung:	Invention relates to an internal combustion piston engine (10) comprising an arrangement (20) for introducing additional oxygen containing gas in- to the cylinders (14) of the engine (10). The arrangement (20) for introducing additional oxygen containing gas comprises a control fluid conduit (36) for introducing the pressure medium to the pneumatically operated actuator device (28) of the injection valve (24), the control fluid conduit (36) is provided with a first control valve (30) and a second control valve (32) arranged parallel in the control fluid conduit (36) for control the fluid communication to the pneumatically operated actuator device (28) of the injection valve (24) and the control fluid conduit (36) is provided with a switch valve (34) arranged to provide a flow connection of the control fluid conduit (36) alternatively with one of the first control valve (30) and the second control valve (32). The invention relates also to a method of starting an internal combustion piston engine (10) and a control unit (70).
