Abstract
A piston (10), a spring (15) operatively coupled to a piston, the spring being inside (21) or outside (41) the piston, and if the spring is inside the piston, the diameter of the spring is equal to 0.7 to 0.9, and if it is outside of the piston it is an external coil spring which is outside the cylinder which contains the piston and is able to provide a force of thousands of pounds per inch, and furthermore so that at light load the compression ratio (CR) is greater than 13 to 1 designated as CR0, at medium load has a compression ratio less then CR0 but greater than CReff, and at wide open throttle (WOT) has a CR equal to Creff, the CR is less than CR0 as would occur at medium or higher load which would lead to a flexing of the spring, and the cycle on the compression stroke is known as the HCX cycle where the pressure goes between Ppre and less than or equal to Pf.
