Four-stroke internal combustion engine of power transmission, sucks and fills gas and/or fuel gas mixtures in one pair of compression/suction chambers, in respective pair of compression/combustion chambers in primary stage by pistons

摘要

The engine has cylinder units (1,2) with double pistons (13-16) connected respectively to form double piston units (11,12). The pistons are set in respective compression/suction chambers (7-10) and compression/combustion chambers (3-6). The gas and/or fuel gas mixtures in one pair of compression/suction chambers are sucked and filled in respective pair of compression/combustion chambers in primary stage and mixtures in other pair of compression/suction chambers are sucked and filled in respective other pair of compression/combustion chambers in secondary stage by pistons.
