    摘要: The present invention is a linear internal combustion free-piston engine with three acting pistons per combustion chamber, that has the ability to store energy until needed. This engine utilizes a spring to store potential energy after combustion. The present invention also introduces additional air into the combustion chamber during the combustion cycle providing a more complete burn of the fuel, has the ability to self-start, and does not idle. Multiple engines can be married together and run as a single unit.

    摘要: A high order of thermal efficiency is achieved in a steam engine or steam expander having a piston clearance that approximates zero together with a negligible amount of compression, such that pressure in the clearance volume approximates ambient pressure, i.e. atmospheric or condenser pressure as the case may be at the end of the piston return stroke when the clearance is essentially zero and constitutes a new engine apparatus and Rankine operating cycle that can be referred to as “zero clearance with zero compression”. The steam admission valve assembly can be operated either automatically responsive to piston contact or by means of a cam shaft or electrically by means of a solenoid. A normally open exhaust valve permits residual steam to be exhausted through the piston return stroke, closed by the piston or cam then held closed by a fresh charge of steam.

    摘要: A high order of thermal efficiency is achieved in a steam engine or expander having a piston clearance that approximates zero together with a negligible amount of compression, such that pressure in the clearance volume approximates ambient pressure, i.e. atmospheric or condenser pressure as the case may be at the end of the piston return stroke when the clearance is essentially zero. These two provisions working together simultaneously provide a method and apparatus which constitute a new engine apparatus and Rankine operating cycle that can be referred to as “zero clearance with zero compression”. The invention also provides an improved steam admission valve assembly that can be operated either automatically responsive to piston movement or by means of a cam shaft and cam or electrically by means of a solenoid that provides an intermittent magnetic field for operating one or more valves. A biphasic exhaust system is described in which a piston operated valve opens to exhaust steam in a primary phase at or near maximum displacement, and in a secondary phase an auxiliary, normally open exhaust valve facing the top of the piston permits virtually all residual steam to be exhausted through the approximate end of the piston return stroke after which it is closed by the piston, by a lifter on the piston or by the cam and finally held closed during the power stroke by a fresh charge of steam injected through the steam admission valve into the clearance volume as it approaches zero.

    摘要: A high efficiency combined cycle internal combustion and steam engine includes a cylinder having a piston mounted for reciprocation therein with an internal combustion chamber outward of the piston, a fixed cylinder cap sealingly and slidably mounted within the piston and a steam expansion and recompression chamber inside the piston adjacent the cylinder cap. The cylinder cap can be unheated or heated externally to reduce condensation of steam entering the steam chamber from a steam generator fired by waste combustion heat. After a steam exhaust valve closes at the top center position, residual steam is recompressed during an inward stroke of the piston up to admission pressure prior to admitting the next charge of steam. A wrist pin that is connected to an inner part of the skirt of the piston and located inwardly of the cylinder cap is coupled to a connecting rod that is secured at its inner end to a crankshaft. One valve or a pair of retractable steam inlet valves connected in series within the cylinder cap inside the piston act in cooperation with steam recompression and a variable clearance volume to achieve an effective zero steam chamber clearance and a gain in mean Rankine cycle temperature to maximize efficiency. The amount of steam admitted each outward stroke is continuously regulated to reduce fuel consumption. Engine coolant can be evaporated in an engine cooling jacket to form steam that is superheated in a combustion exhaust manifold.
