Abstract
A cycle residual boost and two release cavities are provided on a cylinder wall. Wankel cycle air pump is provided with additional cavities which allow the pressure output higher than its fixed compression ratio and further increase compression efficiency. An apex seal active tracking mechanism is also provided. Wankel cycle air pump rotor plates passage makes apex seals keep firmly contact against a cylinder.
