Internal combustion engine/generator with pressure boost

An improved internal combustion engine having compression and power strokes, comprising:

• at least one cylinder;
• a piston movable coaxially within said cylinder, said piston having at least one cam follower;
• an endless cam track driven by said at least one cam follower, said cam track being configured to permit the independent movement and acceleration of said piston during said compression and power strokes based upon at least one parameter;
• means for introducing air and fuel into said cylinder and compressing said air and fuel during said compression stroke;
• means for combusting said air and fuel to initiate said power stroke, whereby the combustion of said air and fuel serves to drive said piston and said cam follower;
• and
• means for introducing a rapidly expanding medium comprising liquid water into said cylinder during said combustion, whereby said medium transforms into an increased-volume gas to increase the pressure within said cylinder, reduce the temperature within said cylinder, and further drive said piston.
