The utility model advantage and effect: at first: a kind of new thinking has been set up in the utility model and design, changed two kinds of old ideas---promptly set up the internal combustion engine thinking of circularly moving piston, changed that piston in the past pumps and the idea of compressed action.

The fuel utilization ratio that improves internal-combustion engine is everybody common pursuit, realize this target, and this just requires us must set up new model utility and mentality of designing, changes in the past old idea.In recent years, some of motor-dom or internal-combustion engine circle it is believed that: " compression ratio of motor car engine is big more, and the explosive force that the mixed gas burning produces is just strong more, and the power of motor is just big more ".I think that this saying is unscientific saying.Should: large-scale combustion is complete more more to contain the composition (concentration) of effective fuel in the mixed gas, and the explosive force that is produced during the mixed gas burning is just strong more, and the power of motor is just big more ".And it is irrelevant with compression ratio.Taking petrol engine is example: the behavior of compressed mixed gas in the petrol engine work is the structural behavior that can't avoid intrinsic on this kind machine construction.This behavior is the process of an effort wasted work, is the primary factor that has reduced engine power.This says that the saying of compressed mixed gas generation explosive force is unscientific saying in the Gasoline Engine Working Process, runs counter to the saying of law of conservation of energy especially, and the explosive force of petrol engine all comes from fuel, never is compression.

Make the piston that has the campaign-styled internal-combustion engine of piston linear now become the curve circular movement of piston from straight line motion in addition, increased the working stroke of piston, reduced the energy dissipation of expanding gas, eliminated the piston connecting rod of straight line moving type internal-combustion engine and the energy dissipation of crank up and down, eliminated piston up and down during straight line moving type internal-combustion engine compressed mixed gas for internal-combustion engine energy unnecessary consumption.Also overcome simultaneously existing rotary internal combustion engine acting---be to defeat the end that combustion chamber volume is relatively little, strength is weak relatively and the directed bonding force that produces promotes that rotor does that orientation rotatablely moves and the energy dissipation of doing work (output work=hold greatly merit-small end merit) by combustion chamber volume one end big relatively, that strength is strong relatively.

The utility model and design have realized: effectively reduce existing internal-combustion engine the chemical energy of fuel is converted into the energy consumption of machine self in the mechanical energy process, improved the fuel oil utilization ratio.Ten big advantages of circularly moving piston internal combustion engine:

1, because of the revolutionary character of internal-combustion engine machine structure changes, piston rotates energy consumption when no longer doing meaningless pressurized gas along circumference, has improved the efficiency of internal combustion engine.2, the circumference of piston rotates the work distance prolonged expanding gas, has increased the working stroke of piston, and more effective minimizing fuel consume has been saved the consumption of the energy, has improved the fuel utilization ratio of internal-combustion engine.3, the piston that rotates of circumference is in the tangent direction of floral disc all the time, makes expansion thrust all the time on the moment loading line of maximum, makes the power of internal-combustion engine more powerful.4, circular floral disc transmits torsion accurately, reliably, directly.5, system architecture is clear, and technology is simple, and the vibrations swing is little, and noise is little; 6, do not have compression process, so this internal combustion engine start resistance is little, inertia is big; 7, the every rotation half cycle of the central shaft of circularly moving piston formula petrol engine, corresponding piston is last and following some acting altogether simultaneously about just having two, they are in 2 thrusts that are subjected to expanding gas respectively up and down, as ion accelerator---successively quicken.It is big to produce output torque, the effect of powerful; 8, circularly moving piston internal combustion engine is when the bigger power of needs.Be convenient to along central shaft series connection assembling; 9, pump four big birth defects of formula internal-combustion engine of conventional piston have effectively been overcome; 10, circularly moving piston internal combustion engine is because of its lowering and work-saving and successively afterburning effect, and do not have idle work consumption, will save the gasoline energy consumption, increases exponentially the fuel efficiency of petrol engine.
