摘要： A high efficiency uniflow steam engine having automatic poppet valves yieldably based by fluid such as steam held under pressure within a cavity in the engine and a cutoff control for closing a steam inlet valve at any time selected stops the flow of steam into the cylinder. Proximate the end of the exhaust stroke, around 0.12 inch before TDC the cylinder is sealed to thereby compress residual steam as the piston clearance approaches zero; typically, 0.020 inch which raises cylinder pressure enough to open an inlet valve without making physical contact to push the inlet valve open with the piston thereby eliminating a tappet type of noise, shock and wear.

摘要： A mechanically simplified electric and fluid (gas, vapor or liquid) control for a piston engine, including an engine valve actuator system that eliminates rotating cam shafts and heavy internal combustion engine valve closing springs by using an electromagnet and an armature which is attracted by the electromagnet to initiate movement of both a fluid control valve and the engine valve. When the control valve is moved only slightly off its seat by the armature, fluid pressure instantly drives the control valve a much greater distance closing the engine valve. Opening and closing time is regulated independently. Engine valves are opened by reversing the fluid pressure balance across the control valve at the time selected.

摘要： The coolant in the cooling jacket of a dual cycle internal combustion steam engine is intentionally maintained at an elevated temperature that may typically range from about 225° F.-300° F. or more. A non-aqueous liquid coolant is used to cool the combustion chamber together with a provision for controlling the flow rate and residence time of the coolant within the cooling jacket to maintain the temperature of the coolant at a selected elevated temperature that is substantially above the boiling point of water but below the boiling point of the coolant. The coolant is passed from the jacket through a heat exchanger in a first circuit to transfer heat to a vaporizable working fluid such as water and is then returned. An optional second circuit is an intrajacket perturbation circuit within the engine can be used to disrupt and disperse pockets of vapor that may tend to form before damaging hot spots can develop around the combustion chamber. A cooling jacket design is tailored to extract heat at the highest possible temperature from each heat transfer zone as by having the coolant follow a circuitous helical pathway to achieve more efficient and improved heat transfer from the combustion chamber to the cooling medium.

摘要： A combination internal combustion and steam engine includes a cylinder having a piston mounted for reciprocation therein with an internal combustion chamber and a steam chamber in the cylinder adjacent the piston and at least one steam exhaust port positioned to communicate with the steam chamber through the wall of the cylinder for exhausting steam at a location in the cylinder wall adjacent to an engine cylinder cap surface that is heated externally to assist in reducing chilling or condensation of steam entering the steam chamber from a boiler fired by waste combustion heat. The invention also permits steam admitted from a steam chest jacketing the cylinder cap to be exhausted from the engine when the steam chamber is in an expanded state whereupon residual steam is then recompressed prior to admitting the next charge of steam with the stream in the steam chamber being heated directly by the combustion chamber as well as by heat from the steam chest. An I.C. exhaust powered heater is a part of an I.C. exhaust manifold which functions as an afterburner with supplemental air injection for promoting combustion of unburned exhaust constituents to superheat steam that is piped through it to the steam chest. The invention provides valves for balancing steam engine displacement with boiler output and for cylinder compounding with a boiler, heat exchange and control arrangement for efficiently recovering waste heat.

摘要： Although internal combustion engines typically waste about 75% of their fuel energy, this invention can provides 31% or more brake horsepower than the engine alone by using anhydrous organic racing engine coolant or other anhydrous organic heat transfer fluid arranged to spiral around a combustion chamber until heated to over 250° C. without boiling while exceeding the boiling point of a separate working fluid that is heated by coolant then superheated by exhaust gas before entering a unique positive displacement vapor expander engine having a piston connected by a clutch to a driveshaft that is also driven by the combustion engine to create a high efficiency direct mechanical powertrain which avoids losses of about 15% had a generator charged a battery powering an electric motor-generator connected for regenerative braking to charge batteries. Highly elevated coolant temperatures also reduce cylinder and exhaust temperatures to lower emission toxicity while preventing lubricant burnout.

摘要： A high efficiency steam engine or steam expander includes a cylinder, cylinder head and piston in which cylinder clearance volume is zero or nearly zero together with a negligible amount of compression such that any pressure in the cylinder clearance volume just before the power stroke is as low as ambient pressure or condenser pressure to provide superior thermal efficiency in a compact compound engine having a high pressure expansion chamber within the piston and low pressure chamber in the cylinder. The inlet valve is opened slightly by piston movement and a steam assist force then drives it to its fully open position. Steam passes from the high pressure chamber to the low pressure chamber through a transfer valve located in the head of the piston and steam is released through an automatic exhaust valve in the cylinder head.

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 with a combustion chamber outward of a piston, a cylinder cap slideably mounted within the piston and a steam expansion chamber inside the piston. The cap can be heated to reduce condensation of steam. Steam remaining when a steam exhaust valve closes can be recompressed prior to admitting the next charge of steam. One valve or a pair of steam inlet valves connected in series act in cooperation to help maximize efficiency. The amount of steam admitted each stroke is regulated by shifting the phase of one steam admission valve of a pair to vary their overlap for determining the steam mass admitted each cycle. Other valves balance steam displacement with the steam generator output to use steam more efficiently.
