Description
Technical field
The invention belongs to the technology of the heat energy of internal combustion type power plant, relate in particular to a kind of semi-free piston linear generator set to the electric energy conversion.
Background technique
Traditional internal-combustion engine-generator set, at first piston-cylinder the part by piston internal-combustion engine is the past complex line machine power of piston with the thermal power transfer that fuel combustion discharges, by crank-linkage mechanism part the past complex line machine power of piston is converted to rotating machinery power again, then with these rotating machinery power some medium taches of process such as coupling, transfer case etc., the conversion of mechanokinetic transmission, shunting and kinetic parameter is converted to electric power by rotary generator with mechanical energy at last.This group shot is widely used, but has following significantly drawback: 1. by two independently energy conversion unit---internal-combustion piston engine, rotary generators, combine by the intermediate connecting ring joint.Heat energy is long to the conversion and the transfer route of electric power, and efficient is low, and energy dissipation is serious.2. owing to piston in the system directly links to each other with connecting rod, the piston lateral force that the swing of connecting rod causes is bigger, has not only caused the mechanical efficiency loss, has caused wearing and tearing and extra heat load between piston and casing wall simultaneously; 3. connecting rod participates in the transmission and the conversion of whole power, connecting rod be subjected to force intensity big, the frictional loss at each articulating point place is serious, the ricing of system running is big.4. crankshaft rod system complexity, heaviness, waste of raw materials is serious, cost of production and operating cost height.
The more above-mentioned traditional internal-combustion engine of electric power free-piston engine EFPE-generator set assembly system has had a lot of improvement.By linear electric generator, realize of conversion and the output of piston linear mechanical energy to electric energy.But itself there is more technical problem in the EFPE scheme:
1. start-up system complexity, subsystem drives difficulty, is difficult to realize regularly, co-ordination; 4 stroke mode of operations, multi-cylinder interlock are difficult to realize.
2. do not have fixedly stop, no fixed journey system, alterable compression ratio is though realize that easily operating mode stability is difficult to control by adjusting the combustion process that compression recently improves motor; In order to pursue efficient low-discharging, require accurate control simultaneously, cause control system comparatively complicated, be difficult to solve compression ratio.
3. the supply timing complex structure of fuel causes the control of compression ratio, firing pressure etc. to become uncertain, and the fuel delivery per cycle control accuracy also requires much higher than conventional engines, thus the difficulty of bringing fuel oil supply system to make.
4. the kinetic characteristic of moving element is a non-sinusoidal nature, piston motion is asymmetric near the dead center position, and braking section is longer than accelerating sections, compare with legacy system, variation has taken place in heat energy-mechanical energy and mechanical energy-power conversions environment, transfer process is brought influence, be difficult to directly realize the performance characteristic and the performance of legacy system.
5. under top speed the same terms, has bigger acceleration.Because structural imbalance, cause the reciprocal inertia force can not homeostasis, cause system works to impact and unstability increases, the vibration problem that causes thus need take additional means to solve;
6. owing to piston " freedom ", so the speed governing difficulty; Because of there not being wheel action engine misses phenomenon serious, cause the functional reliability variation of motor.
