Title: Explosion engine with several combustion chambers

Abstract: Two cylinders of a Diesel or gasoline engine are connected by a pipe leading into ports of the combustion chambers which are simultaneously uncovered by the respective pistons at the beginning of the exhaust phase of one chamber and the end of the intake phase of the other. During this temporary communication, the residual energy of the exhaust gases in said one chamber compels air in said tube to supercharge said other chamber. Passageways are provided in the pistons which connect said pipe with air inlet and exhaust manifolds to ensure scavenging of the pipe between the supercharging periods.
