ABSTRACT:
A double piston engine has a doubly acting piston reciprocably provided in a cylinder arrangement to form two working chambers which periodically increase and decrease their volumes. The invention provides inlet means with supply means for a cleaning flow through the working chambers and inlet means and supply means for a loading flow in excess of atmospheric pressure to the respective chambers. Means are further provided to secure that the loading flow enters the respective working chamber after the closing of the inlet for the cleaning flow. By this arrangement of the invention it becomes possible to operate two cycle engines with turbo-chargers or other loaders. A very powerful engine at compact space and low weight is obtained, while the poisenous gases of two stroke engines are prevented to a high degree.
