Реферат: According to a first aspect, the present invention relates to a combustion engine comprising, a first controllable engine valve (8) arranged to selectively open/close a combustion chamber (7) included in the combustion engine (1), and a gas handling system arranged to drive said first engine valve (8), which gas handling system comprises a closed pneumatic pressure fluid circuit, wherein the closed pressure fluid circuit comprises, coupled in series with each other, a compressor (31) and a valve actuator (10) that are operatively connected to said first engine valve (8). The combustion engine is characterized by the gas handling system further comprising a gas accumulator (38) that is connected with the closed pressure fluid circuit via at least one gas accumulator conduit (39), which includes a controllable valve (40). According to a second aspect, the present invention relates to a gas handling system for pneumatic control of a valve actuator.
