    Abstract: Hydraulic engine valve actuation systems and methods for internal combustion engines. The systems utilize a proportional valve to regulate the flow of a working fluid to and from a hydraulic actuator controlling the engine valve position. The position of the proportional valve is controlled by one or more high speed valves to control various engine valve parameters, including engine valve takeoff and landing velocities. Returning all valves to a known starting position between engine valve events avoids accumulation of errors in proportional valve positioning. Embodiments using spool valves for the high speed valves and the proportional valve, and spring return and hydraulic return for the engine valve, are disclosed. A specially shaped spool in the proportional valve provides enhanced control over the engine valve operation. Various further alternate embodiments are disclosed.

    Abstract: The present invention relates to an eight-phases engine having high thermal efficiency and low polluting emissions and which is formed by an internal combustion engine and a heat exchanger due to the fact that it makes use of the residual heat of the exhaust gases of a first exhaust stroke of the internal combustion engine to heat a portion of the air admitted by the cylinder in the intake stroke, which subsequently flows into an ancillary tank subsequently used to carry out the charging and expansion of said air in the interior of the cylinder and subsequent evacuation thereof, once the first six phases have been completed: intake, first compression, transfer, second compression, first expansion and first exhaust.
