The multi-cylinder piston engine (20) comprises means (24) for introducing combustion air into the cylinders (19) of the engine (20) and at least one cam-operated valve lifting device (4) for each cylinder (19) of the engine (20), the valve lifting device (4) being arranged to open a gas exchange valve (24, 25). The engine (20) further comprises an arrangement for injecting additional oxygen containing gas into the cylinders (19) of the engine (20), the arrangement comprising a pressure medium source (18) for supplying the additional oxygen containing gas,an injection valve (10) in connection with each cylinder (19), means (21) for connecting the pressure medium source (18) to the injection valves (10), and a control valve (12) for each cylinder (19) of the engine (20) for controlling the operation of the injection valve (10). Each control valve (12) is arranged to be operated by a gas exchange cam (1) of the respective cylinder (19). |
