Abstract
A two-cycle diesel engine comprising a diesel head and a combustion chamber whose size is variable upon movement of a flexible fluorocarbon membrane. The diesel engine has an engine cylinder in which a reciprocating piston is disposed. The combustion chamber is positioned above the piston and bounded on top by the membrane. Since fuel ignition occurs because of the heat from the compression of air in the combustion chamber, the rate of firing of the engine can be altered by changing the chamber's size. This is accomplished by a flexing and unflexing movement of the membrane which is selectively controlled by a contra piston and screw mounted in the diesel head above the membrane.
