Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Please refer to Fig. 1 a-Fig. 1 c, internal combustion engine power plant comprises cylinder 100, cylinder being provided with cylinder head 110, cylinder head be formed below suction port 111, cylinder and is provided with relief opening 120.
Piston 200 under the drive of crankshaft-and-connecting-rod in the to-and-fro motion of cylinder 100 Inner eycle.Also be provided with movable part 300 in cylinder, movable part 300 can move between initial position and terminal position, and initial position is higher than top dead center, and terminal position is higher than lower dead center.Movable part 300 has relative first surface 310 and second surface 320.
Movable part 300 is also provided with the gas channel 330 that can close or open.In the present embodiment, gas channel 330 is by closed check valve or open.Certainly also by other controlling methods such as solenoid valves, gas channel 330 is opened or closed.
Movable part 300 is fixed with connecting rod 400, connecting rod 400 can drive movable part 300 to move in cylinder 100.The mode driving movable part 300 to move in cylinder 100 has multiple, such as telescopic flexible rod is set between movable part 300 and piston 200, or movable part is made up of permeability magnetic material, such as each metalloid material etc., described cylinder is outside equipped with the controllable magnetic field that movable part can be driven to move up and down, such as at the outer winding around of cylinder, by changing the both positive and negative polarity of coil to change magnetic direction.
In gas discharge process, the gas channel on movable part 300 is closed, thus waste gas and live gas is kept apart.When needs make live gas to be entered between movable part 300 and piston 200 for the compressed action used time by gas channel, gas channel is opened.After live gas fills movable part 300 and piston 200, then gas channel is closed.
The schematic diagram of the first operation method of internal combustion engine power plant in the utility model one embodiment is please shown referring again to 1a-Fig. 1 c, Fig. 1 a-Fig. 1 c.
Acting: piston 200 is in top dead center, and movable part 300 is in initial position, and after the pressurized gas knocking fuel between piston 200 and movable part 300 second surface 320 expands, piston 200 is run to lower dead center by top dead center.
Air inlet and exhaust: when piston 200 crosses the relief opening 120 being arranged on cylinder lower end, relief opening 120 is opened, connecting rod 400 is driven movable part 300 to move downwardly to terminal position by initial position and is discharged by relief opening 120 by waste gas.When movable part is moved downward by initial position or after movable part moves downward by initial position, live gas enters in cylinder by the suction port 111 be arranged in cylinder head, namely enter movable part terminad position and run the packing space 500 formed.Specific in the present embodiment, namely this packing space 500 refers to the space formed between movable part first surface 310 and cylinder surfaces and cylinder head.In air inlet and exhaust process, the gas channel 330 on movable part 300 is closed condition.
In the present embodiment, in air inlet and exhaust process, live gas and waste gas are separated by movable part, and the two can not mix.In addition, in the present embodiment air inlet and exhaust carry out simultaneously, intake efficiency is high, air inlet and exhaust needed for time few.
After waste gas is drained, relief opening 120 and suction port 111 are all closed, movable part 300 upwards returns back to initial position, in the process returning back to initial position, gas channel 330 is opened, and makes the live gas in packing space 500 be transferred to the compression volume 600 between movable part second surface 320 and piston 200 by gas channel 330.
Compression: after live gas has shifted, gas channel 330 is closed, piston 200 upwards runs the live gas of compression compression volume 600.
Piston moves to atdc, makes the pressurized gas combustion explosion expansion work between piston 200 and movable part 300 second surface 320.So move in circles.
Further, more clean for making waste gas discharge, in the present embodiment, the terminal position of movable part 300 is positioned near on the upside of relief opening 120, when piston 200 runs, relief opening 120 is opened downwards, movable part 300 by initial position move to downwards terminal position with by waste gas discharge after, movable part 300 stops at terminal position, piston 200 continues to move to lower dead center and is run to top dead center by lower dead center, when piston 200 is soon close to movable part 300 second surface 320, relief opening 120 is closed, and movable part 300 returns back to initial position rapidly.
More preferably, for making the compression ratio of internal combustion engine power plant in the present embodiment can regulate according to the actual operating state of internal-combustion engine, in the present embodiment, the initial position of movable part is adjustable.After regulating movable part initial position, piston is moving to atdc, the stereomutation between piston and movable part second surface, thus changes compression ratio.
More preferably, also by the modes such as such as turbosupercharging change enter live gas in cylinder pressure to adapt to the change of compression ratio, situation occurs to avoid pinking maybe can not light a fire etc.
Due in the present embodiment, waste gas is discharged by exhaust outlet with speed faster by movable part, and air pressure when discharging for utilizing waste gas, the relief opening of the present embodiment is connected to turbine pump.
In order to improve the combustion efficiency of the present embodiment internal combustion engine power plant further, before acting step, also comprise the step of adjustment fuel type.
Please refer to Fig. 2 a-Fig. 2 c, the utility model also provides the operation method of another kind of internal combustion engine power plant, comprises step:
Acting: piston 200 is in top dead center, and movable part 300 is in initial position, and after the pressurized gas knocking fuel between piston 200 and movable part 300 second surface 320 expands, piston 200 is run to lower dead center by top dead center.
Exhaust: relief opening 120 is opened, movable part 300 terminad position is run to be discharged by waste gas; Now, the gas channel of movable part 300 is in closed condition.
Air inlet: after completing waste gas discharge, relief opening 120 is closed, and movable part 300 returns back to initial position, air inlet open, and gas channel is opened, and live gas is directly entered between movable part and piston by gas channel and uses for compressed action.
Compression: inlet close, gas channel is closed, and piston runs until reach top dead center to movable part.
In this operation method, air inlet and exhaust are separately carried out.
This operation method still can adopt other preferred steps in the first operation method, such as, adjust movable part initial position to adjust compression ratio, adjustment live gas pressure, adjustment fuel type etc.
Please refer to Fig. 3, the utility model additionally provides the second preferred embodiment of internal combustion engine power plant.In figure 3, the cylinder of internal combustion engine power plant does not arrange cylinder cap, and on the contrary, cylinder head is opened wide, and form opening 110 ', opening 110 ' is connected directly to intake duct 111 '.After adopting this kind of mode, eliminate the cylinder cap of traditional cylinder, live gas can enter packing space more fast simultaneously.
The utility model also provides a kind of motor, comprises above-mentioned internal combustion engine power plant.
Because the efficiency mass ratio of internal combustion engine power plant is high, therefore motor can, according to different operating modes, adopt different fuel oils to reach best running state.Therefore, in a preferred embodiment, motor also includes the switch piece of changeable different fuel type.Such as switch the gasoline of different model, even switch diesel oil and gasoline.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
