Machine or they requisite combustion chambers being formed with a constant volume on top land and cylinder head of four-cycle diesel internal combustion engine,
This combustion chamber volume is changeless, exhaust stroke piston from high point to low spot time, it is impossible to will be left in combustion chamber
Waste gas is discharged, when intake stroke, it is also difficult to suck more fresh air.Therefore, cause existing combustion engine powered deficiency, combustion
Oil consumption increases incomplete combustion, causes entering in air by the pernicious gas of unburned burning-out, the ring that the harm people depend on for existence
Border.
Owing to the bags of traditional internal combustion engine is fixing, it is difficult to increase the crank of I. C. engine crankshaft
The power of engine, owing to the crank of traditional combustion engine is shorter, causes the stroke up and down in piston-cylinder short, flammable in cylinder
The time that gas acts on piston area is short, causes the insufficient and inefficient of burning.
Three, summary of the invention
The purpose of the present invention overcomes disadvantages mentioned above exactly, it is provided that one sets up valve piston and spring at existing internal combustion engine
And the mechanical device of valve piston ring.When exhaust pition to top dead centre, the bags of top land is the least, is discharged by waste gas
Totally；When compression piston is to top dead centre, the air pressure of top land is of a relatively high, and valve piston is at big piston up-downgoing, self-assembling formation
Combustion chamber, reach improve internal combustion engine power, save the energy and reduce pernicious gas purpose.
The internal combustion engine in the past used, when piston compression arrives upper point, has a constant volume between top land and cylinder cap
Combustion chamber, this bags is changeless, therefore, causes piston when exhaust, it is impossible to by the bags
Waste gas is discharged, and during air-breathing, it is also difficult to suck more flammable fresh air, so causes the combustion engine powered deficiency of crude oil, and fuel oil increases
Add, give off unburned sufficiently a large amount of pernicious gases.
The technical solution adopted for the present invention to solve the technical problems is: the piston used by conventional internal combustion engine, piston
Pin-and-hole moves down, and is constructed to embed the circular hole of valve piston, within one week, is provided with installation compression ring and oil ring on the top of valve piston in the middle of piston
Annular groove, the outer, bottom of valve piston be provided with on valve piston shifting location snap ring, at bottom and the piston pin hole of connecting rod of valve piston
Top between be provided with the spring that valve piston moves up and down.When exhaust, exhaust valve is opened, and big piston is together with moving on on valve piston
During stop, the air pressure of top land is relatively low, valve piston under the spring-force driven dual of its underpart on move to size top land plane put down
Together.Reach the bags little, by clean for waste gas discharge；During intake stroke, big valve piston goes downwards to lower dead center simultaneously, more
Suck the fresh air being available for burning；During compression stroke, when big valve piston moves on to top dead centre on simultaneously, due to, inlet and exhaust valve closes
Closing, now the air pressure of top land is slightly higher, makes valve piston be moved down by after atmospheric pressure, the combustion needed for the self-assembling formation of valve piston top
Burn room；During expansion stroke, the air pressure of top land is higher, and valve piston top is by bigger atmospheric pressure, and valve piston is further
Move down, absorb now bent axle and be difficult to absorb the energy rotated, when the descending top land space of big piston acting becomes big, valve piston
Upper shifting, fills the space of top land and releases energy under spring force.
The invention has the beneficial effects as follows
The present invention has additional valve piston and spring and size piston ring on original quartastroke engine piston
Plant equipment, overcomes conventional combustion chambers of internal combustion engines volume and immobilizes, and air-breathing is less and is vented incomplete deficiency, structure letter
Single, cost is low, stable and reliable in work.The present invention implements to improve the power of internal combustion engine early, saves fuel oil, reduces into
This, reduce the discharge of pernicious gas, be the another item significant innovation after internal combustion engine has booster.
