|4352343||Constructional improvements in a two-stroke opposed piston engine operating with stratified charge|
The invention relates to an improvement in a two-stroke internal combustion engine with opposed cylinders of different diameters which communicate by way of a combustion chamber of bell configuration for radially stratifying the rich mixture charge fed ta...
|4296714||Dual piston two stroke engine|
A two stroke internal combustion engine with at least one dual piston, the cylinders of which are connected to each other by a combustion chamber on the cylinder head side. The engine can be charged on the crank chamber side with an air or air/fuel mixtur...
|4079705||Two-stroke-cycle dual-piston internal combustion engine|
In a two-stroke-cycle dual-piston engine in which a fuel mixture is compressed in the crank chamber by the reciprocating pistons, the compressed fluid flows from the crank chamber and a compartment of one cylinder open toward the crank chamber through a t...
