Abstract
The utility model relates to a kind of twin-tub cover motor, comprise the outer cylinder sheath be fixed on cylinder body, and to be coaxially arranged in outer cylinder sheath and the inner cylinder liner be slidably matched with outer cylinder sheath, piston to be built in inner cylinder liner and to be slidably matched with inner cylinder liner, cylinder cap is fixed on the top of inner cylinder liner, the top of cylinder cap is also provided with a driven unit for driving cylinder cap, inner cylinder liner descending, the upper end of inside and outside cylinder sleeve has an annular protrusion radially stretched out respectively, between two annular protrusions of inside and outside cylinder sleeve, be provided with reset assembly.The utility model has the advantage of: the utility model motor adopts inside and outside twin-tub nested structure, roll the piston that makes while top dead center declines by the cycle of cam, the speed that the speed that inner cylinder liner declines simultaneously and declines declines faster than piston, thus improve the compression ratio of fuel further and make descent of piston, the arm of force increases, then light, so just the utilization ratio of power is improved.
Description
Technical field
The utility model relates to a kind of motor, especially a kind of twin-tub cover motor.
Background technique
Fewer and feweri along with Global Oil resource, but no matter increasing to the demand of oil in daily production or military affairs, and utilization ratio is not high, petroleum resources are non-renewable again, therefore economize on resources at present and improve oil utilization ratio concerning critical.
At present, the fuel utilization ratio of motor is between 25% to 30%, utilization ratio is very low, the working principle of its current motor is: air and fuel oil are mixed into good mixed gas in certain proportion, be inhaled in cylinder in suction stroke, mixed gas produces heat energy through compression ignite or ignition, and the gas of High Temperature High Pressure acts on piston head, promotion piston does reciprocating linear motion, by connecting rod, the external output mechanical energy of crankshaft-flywheel mechanism.Four-stroke gasoline engine completes a work cycle in aspirating stroke, compression stroke, expansion stroke and exhaust stroke.Current motor is when piston reaches top dead center, bent axle reaches plumbness substantially, in firing chamber, fuel oil is lighted thermal energy is mechanical energy, now because power is perpendicular to force bearing point, moving direction and Impact direction are close to vertical, and the arm of force is very little, and portion of energy is applied directly on the axle center of bent axle, effective kinetic energy cannot be formed, thus reduce the utilization ratio of fuel oil.
Therefore a kind of new work engine promoting fuel utilization ratio, more energy-conserving and environment-protective is researched and developed imperative.Through retrieval related documents, do not find the arm of force of piston actuated bent axle to be avoided too small at ignition point, and the compression ratio simultaneously in firing chamber reaches maximized new work engine structure.
Model utility content
The technical problems to be solved in the utility model is to provide a kind ofly can avoid the arm of force of piston actuated bent axle too small at ignition point, and the compression ratio simultaneously in firing chamber reaches maximized motor.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of twin-tub cover motor, comprise cylinder body, cylinder sleeve, cylinder cap, piston, connecting rod, described cylinder body is provided with at least one cylinder sleeve, the top of cylinder sleeve is provided with sealing cylinder cap, cylinder sleeve is built-in with piston, piston by connecting rod and bent axle hinged; Its innovative point is:
Described cylinder sleeve comprises the outer cylinder sheath be fixed on cylinder body, and to be coaxially arranged in outer cylinder sheath and the inner cylinder liner be slidably matched with outer cylinder sheath, piston to be built in inner cylinder liner and to be slidably matched with inner cylinder liner, cylinder cap is fixed on the top of inner cylinder liner, and the top of cylinder cap is also provided with a driven unit for driving cylinder cap, inner cylinder liner descending;
The upper end of described inside and outside cylinder sleeve has an annular protrusion radially stretched out respectively, between two annular protrusions of inside and outside cylinder sleeve, be provided with reset assembly.
Further, described driven unit is a cam pack.
Further, described driven unit is connected with a peripheral hardware storage battery.
Further, described driven unit by transmission device to be connected with bent axle realize descending.
The utility model has the advantage of: the utility model motor adopts inside and outside twin-tub nested structure, roll the piston that makes when working stroke by the cycle of cam, the speed that the in good time descending and descending speed of inner cylinder liner declines faster than piston, thus backward delay period of combustion, keep optimum compression ratio simultaneously, thus compression and combustion is fully realized, like this with regard to making the utilization ratio of power be improved, save resource.
Accompanying drawing explanation
Fig. 1 is the working state that the utility model engine piston is positioned at top dead center.
Fig. 2 is the working state that the utility model motor starts to light a fire.
Fig. 3 is the working state that the utility model engine piston is positioned at lower dead center.
Embodiment
A kind of twin-tub cover motor as shown in Figures 1 to 3, comprise cylinder body, cylinder sleeve, cylinder cap, piston, connecting rod, described cylinder body is provided with at least one cylinder sleeve, the top of cylinder sleeve is provided with sealing cylinder cap, cylinder sleeve is built-in with piston, piston by connecting rod and bent axle hinged.
The cylinder body of the utility model device comprises the outer cylinder sheath be fixed on cylinder sleeve, and to be coaxially arranged in outer cylinder sheath 1 and the inner cylinder liner 2 be slidably matched with outer cylinder sheath 1, piston 5 to be built in inner cylinder liner 2 and to be slidably matched with inner cylinder liner 2, cylinder cap is fixed on the top of inner cylinder liner 2, the top of cylinder cap is also provided with a driven unit 3 for driving cylinder cap, inner cylinder liner descending, the upper end of inside and outside cylinder sleeve has an annular protrusion radially stretched out respectively, between two annular protrusions of inside and outside cylinder sleeve, be provided with reset assembly 4.
The driven unit 3 of this motor is a cam pack, and cam pack is connected with a peripheral hardware storage battery.
The driven unit 3 of this motor can also by transmission device to be connected with bent axle realize descending.
Its working principle is: here just for the compression ratio of the highest petrol engine Mitsubishi GPI motor of compression ratio in the market for 12:1, the utility model motor when piston arrives top dead center, inner cylinder liner is also at the highest notch, the compression ratio of firing chamber sky is now less than optimum compression ratio 12:1, descent of piston subsequently, inner cylinder liner also moves down under the effect of cam simultaneously, but the descending speed of inner cylinder liner will faster than the speed of descent of piston, so the space of firing chamber can be more and more less, compression ratio is greatly more next, when runner descending angle in bottom reaches 18 degree to 22 degree, compression ratio reaches best 12:1, now engine ignition, descent of piston operates, inner cylinder liner resets under the effect of Returnning spring, so repeatedly complete engine running.
