Abstract: An internal combustion engine control apparatus that prevents an abrupt change in the air amount at the time of supercharger switching. The control apparatus enters a small turbo operating state in which a small turbocharger is mainly operative, during relatively low-rotation-speed and low-load side, and enters a large turbo operating state in which a large turbocharger is mainly operative, in a relatively high-rotation-speed and high-load. In the small turbo operating state, the control apparatus can exercise charging efficiency enhancement control by using a scavenging effect. Before switching from the small turbo operating state to the large turbo operating state, the control apparatus predicts whether the large turbocharger will build up its boost pressure quickly or slowly. When slow boost pressure is predicted, the control apparatus exercises charging efficiency enhancement control to provide a low degree of charging efficiency enhancement.

Abstract: The present invention is a heat recovery fluid to be used in a closed loop, hot dry rock system, where the fluid remains in a liquid state flowing down from the surface in an annular, downflow conduit to a terminal end heat exchanger. At the terminal end heat exchanger, the heat recover fluid partially vaporizes as a result of indirect heat transfer locally from the geological formation, resulting in a dual-phase fluid or vapor stream flowing out from the terminal end heat exchanger to an axial, return upflow conduit. In one embodiment, the upflow conduit is separated by a single wall from the downflow conduit. When the upflow conduit bears a dual-phase fluid, it has been found that the degree of vaporization of the heat transfer fluid does not result in substantial separation of the vapor and remaining liquid, i.e., which could result in plugging or slug flow in a sloping upward direction, but instead produces a stable flow regime for return of the heated heat recovery fluid to the surface.
