Description
Affiliated technical field
The utility model relates to a kind of motor, especially high efficiency piston internal-combustion engine.
Background technique
At present, known piston internal-combustion engine structure is to be combined by piston, bent axle.In same piston, finish the circulation that a thermal power transfer becomes power after process air inlet, compression, acting, four processes of exhaust.Because compression and acting are carried out in same piston, the acting process at the end specific volume of working medium can only expand into the preceding specific volume of compression, the pressure and temperature of the interior gas of piston this moment is also very high, possess very big acting and heat-transfer capability, but because of there not being the expand acting and conduct heat of enough room and times, can only discharge outside the motor, make engine efficiency lower, waste the energy.
Summary of the invention
Its purpose of the utility model provides a kind of piston internal-combustion engine with regard to being to overcome above defective, overcome the lower problem of available engine efficient, Working medium gas in its piston may be expanded to greater than the specific volume before the compression at acting process specific volume at the end, can increase the output of useful work, gas after the acting is by the preceding pressurized gas of heat exchanger heats acting, can reduce the consumption of fuel, thereby improve the efficient of motor
The technological scheme that the utility model provides to achieve these goals is, this motor is by compression piston, expansion piston, bent axle and heat exchanger constitute, wherein compression piston and expansion piston are equipped with intake valve and exhaust valve, compression piston is equipped with connecting rod with expansion piston and links to each other with bent axle, be provided with heat exchanger between compression piston and the expansion piston, heat exchanger is divided into high temperature chamber and low temperature cavity, and the intake valve of low temperature cavity links to each other with the exhaust valve of compression piston, the exhaust valve of low temperature cavity links to each other with the intake valve of expansion piston, and the intake valve in high temperature chamber links to each other with the exhaust valve of expansion piston.
Air inlet and compression process be placed in the piston finish, (this piston is called compression piston, down with), will do work to be placed in another piston and finish that (this piston is called expansion piston with exhaust process, connect a heat exchanger between compression piston and the expansion piston down together).Gas after the compression piston compression is stored in earlier in the low temperature cavity of heat exchanger, utilizes the high-temperature tail gas that is entered by expansion piston in the heat exchanger high temperature chamber to preheat; Suck in the low temperature cavity of expansion piston automatic heat-exchanger through pre-warmed pressurized gas, under the effect of fuel combustion, expand and do work, the discharge capacity of expansion piston is greater than compression piston, the expansion ratio of expansion piston is greater than the compression ratio of compression piston, the not restriction of piston volume by compression of volume that Working medium gas is expanded, may be expanded to greater than the specific volume before the compression, thereby make full use of the acting ability of gas.The high-temperature tail gas of finishing merit in the expansion piston enters in the heat exchanger high temperature chamber, and the pressurized gas by before the heat exchanger heats acting reduces the consumption of fuel, improves the efficient of motor.
The beneficial effects of the utility model are, overcome the lower problem of available engine efficient, Working medium gas in its piston may be expanded to greater than the specific volume before the compression at acting process specific volume at the end, can increase the output of useful work, gas after the acting is by the preceding pressurized gas of heat exchanger heats acting, the consumption of fuel be can reduce, thereby the efficient of motor, fuel saving improved.
