摘要:
An auxiliary power system for providing electrical power and heat to an indoor area includes an external combustion engine, such as a Stirling cycle engine (101), for generating mechanical energy and thermal energy. The external combustion engine (101) burns a fuel with substantially complete combustion such that exhaust emissions from the external combustion engine (101) are below a predetermined exhaust level. A generator (102) is coupled to the external combustion engine (101) and converts the mechanical energy produced by the external combustion engine (101) to electrical power. A first power output is used to provide the electrical power produced by the generator (102). The external combustion engine (101) and generator (102) are disposed within a housing such that the external combustion engine (101), generator (102) and housing combination is a portable size. The thermal energy generated by the external combustion engine (101) may be used to heat the atmosphere surrounding the housing.

A stirling engine (1) includes a crankcase (9), a crank box (11), and a path (51). A crankshaft (8) for taking power to outside is bridged across the crankcase (9). The crank box (11) is disposed in the crankcase (9). The crank box (11) accommodates a power conversion member (30) that converts reciprocating movement of a piston (3) to rotation movement of the crankshaft (8). A connection route (51) takes a balance between a pressure of a first space (S11) in the crank box (11) and a pressure of a second space (S9) inside the crankcase (9) and outside the crank box (11).

A thermal cycle engine (96) of the type having a piston undergoing reciprocating linear motion within an expansion cylinder, the expansion cylinder having a cylindrical wall and containing a working fluid heated by conduction, through a heater head (100), of heat from an exhaust gas of an external combustor having a fuel supply and a thermal sensor (138) for measuring a temperature of the heater head (100) at a point of maximum temperature of the heater head (100).
摘要:
A method of controlling power output of a Stirling engine having a casing, a displacer slidably fitted in the casing, and a working piston disposed under the displacer and slidably fitted in the casing, comprising the steps of: providing the casing with a bleeding passage extending radially outwardly between the displacer and the working piston, and providing means for adjusting volume of the bleeding passage, whereby the power output of the Stirling engine can be accurately controlled.
摘要:
Thermal machine (12) of the type having a machine body with a main axis extending between a thermal end (16) and a work end (18), said machine body being comprised of a plurality of axial body sections (20, 22), a working fluid at relatively high pressure in a chamber (24) defined in said body and a displacer element (34) reciprocable in said chamber (24) for displacing the working fluid between a hot space and a cold space of said chamber (24) for subjecting the fluid to a thermodynamic cycle in cooperation with a work piston (36), further comprising outer means (56) compressively pre-loading said machine body between said ends (16, 18) for maintaining said body sections (20, 22) in axially assembled operative relationship.
