摘要： Piston assembly (1) for an internal combustion engine comprising an upper section (2) abutting onto the combustion chamber of the cylinder, a piston skirt (3) in connection with the upper section, and a sealing arrangement for sealing the joint between the upper section and the skirt. In the piston assembly the sealing arrangement (1.2, 1.3) between the upper section and the skirt is provided by utilizing the difference between the mounting and working temperatures of the upper section (2) and the piston skirt (3). Preferably, the sealing arrangement between the upper section and the skirt is arranged to operate under working pressure and the sealing arrangement comprises several operationally in succession provided counter surfaces, which are arranged with respect to each other so that their mutual distance is reduced at the working temperature of the surfaces, and that a pressure balancing chamber is formed between two successive, tightly arranged counter surface pairs (2a - 3b).

摘要： An air supply arrangement for piston engine (1) comprising a feed channel (22) for combustion air, through which combustion air is fed into the engine, i.e. into a collecting container (6), to which the channel (22) for combustion air is connected, and from which collecting container (6) combustion air is distributed further to each cylinder (3) of the engine, a feed pipe (11) for each engine cylinder (3), by which feed pipe combustion air is conducted from the collecting container (6) to each cylinder of the engine, and means (17) for introducing moistening fluid into the combustion air. In addition, in the flow direction of the combustion air after the collecting container (6) there is arranged at least one droplet separator (20).
