Abstract
A knocking-based, micro-combustion engine constructed in three layers of micromachined material. Two outer layers contain means for directing gases and fuels into and out of vents in a middle layer. The middle layer has machined in it two, linear, free pistons with or without integral air springs, and vents for directing gases and fuels into and out of a combustion chamber. A high compression ratio is achieved. The engine can be constructed with means to generate electrical energy.
Claims29
A microcombustion engine comprising:
- a substantially planar inner layer attached on opposing surfaces thereof to a pair of substantially, planar outer layers;
- a chamber formed in said inner layer;
- a first piston situated in said chamber;
- a second piston situated in said chamber;
- at least one intake port in said chamber;
- at least one output port in said chamber;
- and
- wherein said first and second pistons are moveable towards each other so as to compress and ignite a fuel so that the force of combustion causes said first and second pistons to move away from each other, resulting in a product of combustion leaving said chamber through said at least one output port and another fuel to enter said chamber through said at least one intake port to be compressed and ignited by said first and second pistons so that the force of combustion causes said first and second pistons to move away from each other.
A microcombustion engine comprising:
- a substantially planar inner layer attached on opposing surfaces thereof to a pair of substantially planar outer layers;
- a chamber formed in said inner layer;
- a first piston situated in said chamber;
- a second piston situated in said chamber;
- a first detector proximate to said first piston;
- a second detector proximate to said second piston;
- a first transducer proximate to said first piston;
- and
- a second transducer proximate to said second piston.
A microcombustion engine comprising:
- a substantially planar inner layer attached on opposing surfaces thereof to a pair of substantially planar outer layers;
- a chamber formed in said inner layer;
- a first piston situated in said chamber and freely moveable along a length of said chamber;
- a second piston situated in said chamber and freely moveable along the length of said chamber;
- and
- a vent situated in said chamber;
- and
- wherein said chamber, first piston, second piston, and vent are micromachined from a material.
A microcombustion engine comprising:
- a substantially planar inner layer attached on opposing surfaces thereof to a pair of substantially planar outer layers;
- a combustion chamber formed in said inner layer;
- first and second linearly opposing pistons situated in said chamber, which pistons are adapted for opposed linear motion in said chamber;
- at least one fuel intake port through at least one of the outer layers connecting with said chamber;
- at least one at least one exhaust output port through at least one of the outer layers connecting with said chamber;
- and
- wherein said first and second pistons are moveable towards each other so as to compress and ignite a fuel so that the force of combustion causes said first and second pistons to move away from each other, resulting in a product of combustion leaving said chamber through said at least one output port and another fuel to enter said chamber through said at least one intake port to be compressed and ignited by said first and second pistons so that the force of combustion causes said first and second pistons to move away from each other.
