The most difference for one kind of the positive-displacement engine from capacity-invariable engine is, the CVE has double pistons interlinked mutually in every cylinder. Inner piston connects with the piston pin by the connecting rod. Outer piston with a ring sits on inner piston supported by the spring. The characteristic of this engine is: Every stroke volume changes diversity. In exhaust stroke, outer piston gets to the tiptop of the cylinder, waste gas almost discharges (exhaust ratio can be to 95%˜98% in theory), compression ratio is improved (≧12); In intake stroke, outer piston continues moving by the inertia at the end of the intake stroke, the air intake volume increases. So it realizes the automatic supercharging and the fuel efficiency and emission have improved.
