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 Rankine cycle system having a working medium circulation circuit (110) that includes an evaporator (112), an expander (113), a condenser (114), and a feed pump (115) is provided in which a mixture of oil for lubricating the expander (113) and water, which is a working medium and has become mixed with the oil, is supplied to coalescer type water separating means (118), thus separating the water from the oil. The oil from which water has been separated in water separating means (118) is returned to the expander (113), and the water separated from the oil is returned to the working medium circulation circuit (110). It is thus unnecessary to replenish the working medium circulation circuit (110) with water or replenish the expander (113) with oil.

摘要： In systems in which there is insufficient pressure difference between the intake and the exhaust to drive the EGR, an EGR pump is provided. In a dual-engine system, disclosed herein, the EGR system, i.e., the EGR cooler and EGR pump, is shared to obviate the need for two of each. Shutoff valves may be provided between the EGR system and a secondary of the two engines to isolate the secondary engine when it is not operating. When the engines are OPOC engines, exhaust aftertreatment devices, such as diesel oxidation catalysts and/or diesel particulate filters, may be placed upstream of where the EGR gases tee off from the engine's exhaust to thereby maintain a high pressure ratio across an exhaust turbine located downstream in the engine's exhaust.

摘要： An engine having a Rankine cycle steam expander includes an engine cylinder, a cylinder head and a piston in which clearance is zero together with a negligible amount of compression, such that pressure in the clearance volume is as low as to approximate ambient pressure or condenser pressure existing at the end of a return stroke when the clearance is zero. These provisions for clearance and compression working together simultaneously provide a thermal efficiency which substantially exceeds all prior known Rankine operating cycles and is referred to as “zero clearance with zero compression”. The steam admission valve is raised slightly by the piston to establish a zero clearance whereupon a steam assist then moves the steam admission valve determinately and quickly to a fully open position.

摘要： A high efficiency combined cycle internal combustion and steam engine includes a cylinder and a piston with an internal combustion chamber outward of the piston, a fixed cylinder cap and a steam expansion chamber inside the piston. The cylinder cap can be heated to reduce condensation of steam entering from a steam generator fired by waste combustion heat. Following exhaust, residual steam can be recompressed prior to admitting the next charge of steam. A wrist pin connected to an inner end of the piston skirt inwardly of the cylinder cap is coupled to a connecting rod secured to a crankshaft. One valve or a pair of steam inlet valves are connected to communicate in series within the cylinder cap inside the piston. The steam mass admitted is regulated to reduce fuel consumption. Coolant can be superheated in the combustion exhaust manifold.
