Patent ID: 7104227

Claim:
An internal combustion engine machine incorporating significant improvements in power, efficiency and emissions control comprising: (a) one or more cylinders, each comprising at least one head, combustion chamber, base, compression chamber and sidewall; (b) one or more means of igniting fuel in the cylinder(s); (c) one or more sources of intake air; (d) at least one means of storing and/or cooling lubricating oil between cycles of circulation; (e) a drive train; (f) at least one means of encasing, protecting, cooling and lubricating the drive train; (g) at least one means of segregating the oil in the sump and/or crankcase from the air or air/fuel mixture in the cylinder, whether within or apart from the combustion chamber; (h) at least one means of dispersing oil on the cylinder walls and of then gathering excess for return to the oil sump; (i) at least one means of transmitting energy to and from the pistons; (j) at least one means of guiding each piston rod such that it moves in a linear manner, always along substantially the same line; (k) at least one means of drawing air or air/fuel mixture into the engine machine, propelling it into the cylinder combustion chamber, compressing it for ignition and propelling its expulsion after ignition; (l) at least one means of admitting air and fuel, or air/fuel mixture into each cylinder apart from the combustion chamber; (m) at least one means of efficiently expelling exhaust gases resulting from combustion of the air fuel mixture after energy has been extracted; (n) at least one means of transmitting energy from the piston rod to the drive train; (o) at least one means of cooling the engine; and (p) at least one means of transporting dispersing gathering and returning lubricating/cooling oil while keeping it segregated from combustion air and fuel; (q) wherein the means of efficiently expelling exhaust gases upon completion of combustion and energy extraction comprises a cylinder head exhaust valve, allowing exhaust to exit through the head of the cylinder.
