<p>The piston compressed turbine engine is controlled by drawing air or air-fuel mixture into the cylinder as the intake valve is open and the piston retreats (a retreat act), pausing the piston at the BDC for a predetermined time so that the delay in intake due to inertia of the inducted air or air-fuel mixture is removed (a pause-at-BDC act), compressing the air or air-fuel mixture as the piston advances (an advancing act), and pausing the piston at the TDC for a predetermined time so that constant volume combustion is performed during explosion and combustion gas rotates the turbine after combustion is completed and then is exhausted (an pause-at-TDC act). Thus, a superior thermodynamic performance analyzed using the air cycle can be obtained along with high output and efficiency. Since the power shaft of the turbine and the shaft of the piston are arranged parallel to each other, a compact engine is possible. Since the emission of contaminants is prevented, the engine is pro-environmental. The control and manufacture of an engine are made easy.</p> |
