Double Piston, Two-Cycle Engine. pistons working in the opposite ends pistons were connected to the enginecrankshaft by an ingenious system of levers andconnecting rods which transmitted the motion ofthe pistons to the crankshaft. The four diagrams of Fig. 6, show the posi-tions of the pistons at different points of thecycle. In the first, the pistons are at one ex-treme of their stroke and are just beginning toseparate.

The charge is now admitted betweenthem through an automatic lift valve. In thesecond, the admission of the charge has beencompleted and the further movement of thepistons is about to close the ports leading tothe admission and exhaust valve. In the third,the charge is compressed and ignited, the result-ing explosion causing the pistons to rapidlyseparate. In the fourth, the exhaust port isuncovered, and the products of combustion dis-charged into the atmosphere. By this method,the several operations of admission, ignition,-expansion, and discharg
