How efficient is a linear generator?
The free piston linear generator can be used in many applications. Due to the expected high electrical efficiencies in the range of 46 % for a Diesel-HCCI-Process [1] the automotive application in the field of APU or even the main drive train is promising.
How does a linear generator work mention its applications?
The free-piston linear generator (FPLG) uses chemical energy from fuel to drive magnets through a stator and converts this linear motion into electric energy.
Do generators have pistons?
The diesel generator piston set consists of a piston, a piston ring and a piston pin. The piston is the pressure of the gas and transmits the force to the crankshaft via the connecting rod. The working condition of the piston is very bad.
How does the mainspring generator work?
The Mainspring Linear Generator – distinct from an engine, microturbine, or fuel cell – directly converts motion along a straight line into electricity using chemical energy. At the heart is our 120 kW linear generator core. Our first product features two cores in each package, working in tandem.
How does a linear generator work?
The Sunpower linear alternator operates, like all generators and motors, through the interaction between a coil of wire and a magnetic field. A changing magnetic field (caused by the motion of magnets attached to the piston) induces a voltage in the coil causing an electrical current to flow.
What is a linear combustion engine?
A LCE is a special type of combustion engine representing a new approach concerning the conversion of the chemical energy of hydrocarbon fuel into electrical energy. Unlike conventional engines, this type of engine does not use a crankshaft, and generates electric energy directly by a linear movement of pistons.
What engine does not use pistons?
pistonless rotary engine
A pistonless rotary engine is an internal combustion engine that does not use pistons in the way a reciprocating engine does. Designs vary widely but typically involve one or more rotors, sometimes called rotary pistons.
What’s the meaning of Mainspring?
1 : the chief spring in a mechanism especially of a watch or clock. 2 : the chief or most powerful motive, agent, or cause.
What is a technology generator?
Electric generator, also called dynamo, any machine that converts mechanical energy to electricity for transmission and distribution over power lines to domestic, commercial, and industrial customers. Generators also produce the electrical power required for automobiles, aircraft, ships, and trains.
Which is used for the permanent magnet in linear electromagnetic generator?
Structure and principle of linear electromagnetic generator A neodymium–ferrite (Nd-Fe) magnet is used for the permanent magnet.
Why is it called reciprocating engine?
A reciprocating engine is an engine that uses one or more pistons in order to convert pressure into rotational motion. They use the reciprocating (up-and-down) motion of the pistons to translate this energy.
