  • VARIABLE COMPRESSION CYLINDER HEAD, CRANKSHAFT, AND PISTON ROD AND SYSTEM THEREOF
    Publication number: 20170218838
    Abstract: A variable compression cylinder head assembly usable with an internal combustion engine having at least one piston, the cylinder head assembly including a cylinder head housing having a combustion chamber formed therein, a compression control piston disposed within the combustion chamber, a compression head actuator coupled to the cylinder head housing, the compression head actuator including an actuator housing defining an actuator reservoir, a fluid port coupled to the actuator housing to receive a fluid, a movable force plate disposed within the actuator reservoir and coupled to the compression control piston, wherein the force plate and the compression control piston move between a first position and a second position when the fluid enters the actuator reservoir.

  • Internal combustion engine machine incorporating significant improvements in power, efficiency and emissions control
    Patent number: 7104227
    Abstract: A two stroke cycle internal combustion engine machine that does not require lubricating oil to be mixed with its fuel, producing greater efficiency, higher power to weight ratio, cooler operating temperatures, a wider speed range, greater simplicity, and lower toxic emissions, many of the improvements also transferable to four stroke engines.
