Enhanced piston for improving the efficiency of an internal combustion engine

An enhanced piston for improving the efficiency of an internal combustion engine comprising:

• a cylinder;
• said cylinder having a combustion chamber and a lower cylinder portion;
• a cylinder head disposed on said cylinder;
• an enhanced piston moveably disposed within said cylinder;
• a piston rod connected to said enhanced piston;
• said enhanced piston having a piston cavity;
• an upper piston valve connected to an upper piston valve rod;
• said upper piston valve disposed within said piston cavity;
• wherein said upper piston valve selectively seals said piston cavity from said combustion chamber;
• a piston cavity port disposed on a bottom portion of said piston cavity;
• a lower piston valve;
• and
• said lower piston valve disposed within said piston cavity port;
• wherein said lower piston valve seals said piston cavity port from said lower cylinder portion;
• wherein gases selectively sealed in said piston cavity are contained under pressure until released in said combustion chamber;
• said lower piston valve having a lower piston valve rod connected to said lower piston valve wherein said lower portion protrudes into a portion of said lower cylinder portion;
• and
• a lower piston valve push rod disposed to protrude into said portion of said lower cylinder portion to intermittently make contact with said lower piston valve rod to selectively open and close said lower piston valve.

An enhanced piston for improving the efficiency of an internal combustion engine comprising:

• a cylinder;
• said cylinder having a combustion chamber and an open cylinder portion;
• a cylinder head disposed on said cylinder;
• an enhanced piston moveably disposed within said cylinder;
• a piston connecting flange on a bottom portion of said enhanced piston,
• a connecting rod moveably connected to said connecting flange;
• said enhanced piston having a piston cavity;
• a piston valve moveably disposed within said piston cavity;
• a piston valve rod connected to said piston valve wherein said piston valve selectively seals said piston cavity from said combustion chamber;
• a piston valve actuator arm connected to said connecting rod;
• said piston valve actuator arm slidably disposed to a lower portion of said piston valve rod and secured to said lower portion with a retainer;
• a spring bracket disposed on said bottom portion;
• a piston valve rod spring retained within said spring bracket wherein said piston valve is biased in a sealed position;
• a piston cavity inlet port disposed within said bottom portion;
• a piston cavity inlet connecting port disposed within said open cylinder portion;
• and
• said piston cavity inlet port adapted to removably fit with said piston cavity inlet connecting port wherein compressed gas is selectively transferred to said piston cavity when said piston cavity inlet connecting port is in contact with said piston cavity inlet port.
