Abstract
The invention discloses a combustor structure in a motorcycle engine. The combustor structure in the motorcycle engine is characterized in that a semispherical concave pit and a piston concave pit are respectively arranged between a cylinder end combustor and a piston, a combustor is composed of the cylinder end combustor and the piston as well as an inlet valve and an exhaust valve so as to divide a combustor; the combustor is composed of two concave pits and isolated from the outside, and two combustors generate a siphon action during power stroke of an engine; a burning mixture can enter into the main combustor more rapidly so as to carry out full combustion, thereby achieving higher work power; and the combustor structure is used in the field of motorcycle engines.
Description
Technical field
The present invention relates to a kind of internal structure of motor car engine parts, particularly relate to the chamber structure in a kind of motorcycle engine.
Background technique
In-engine firing chamber is that fuel or propellant agent burn therein and produce the device of high-temperature fuel gas; In-engine chamber structure in the past is many to be made up of the bottom surface of cylinder head firing chamber, intake valve and exhaust valve, the head of firing chamber inner carrier and the space of the relative closure that piston ring constitutes, and we generally are referred to as the firing chamber space of this relative closure.In the firing chamber, fuel is inhaled into, and compresses and lights, and accomplishes work done, and waste gas after burning emits in the firing chamber more then, to accomplish an expansion stroke.
In the conventional petrol engine; Its cylinder head firing chamber be shaped as hemisphere; The semicircular arc of piston head position protrusion; The setting of this type of combustion chamber components can be convenient to the processing of device and the stack mounting of firing chamber inner structure, but still there is the leeway that can further improve its work done power in this type of in-engine firing chamber.
Summary of the invention
For addressing the above problem, the present invention provides a kind of engine combustion chamber structure that can further improve its work done power.
The technical solution adopted for the present invention to solve the technical problems is:
Chamber structure in a kind of motorcycle engine; Comprise cylinder liner and place the piston in the cylinder liner; Be provided with the cylinder head firing chamber in the outside of piston on the cylinder liner; Be connected with intake valve and exhaust valve on the cylinder head firing chamber respectively, the bottom near piston one side on the cylinder head firing chamber is provided with hemispherical dimples, and the top near cylinder head firing chamber one side on the piston is provided with piston crater.
Further as the improvement of technological scheme of the present invention, the bottom near cylinder head firing chamber one side on intake valve and the exhaust valve is provided with the valve pit, is provided with the valve slot to make way in the side near the cylinder head firing chamber on the piston.
Further as the improvement of technological scheme of the present invention, be provided with piston ring between the outer ring of piston and the inwall of cylinder liner, the outside of cylinder head firing chamber is provided with the cylinder end seal circle.
Further as the improvement of technological scheme of the present invention, the bottom and the piston space of cylinder head firing chamber are provided with the gap.
Beneficial effect of the present invention: the chamber structure in this motorcycle engine is through being provided with hemispherical dimples and piston crater respectively in cylinder head firing chamber and piston space; In the firing chamber of forming by cylinder head firing chamber and piston and intake valve and exhaust valve, be separated out a firing chamber; And the firing chamber that two pits are formed is not hedged off from the outer world; Thereby in the power stroke of motor, in two firing chambers, produce siphonage, make burning mixture can get in the main firing chamber more rapidly; Burn fully, thereby reach higher work done power.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further:
Fig. 1 is an embodiment of the invention internal structure overall schematic;
Fig. 2 is an embodiment of the invention cylinder head chamber structure schematic representation;
Fig. 3 is an embodiment of the invention piston head structural representation.
Embodiment
With reference to Fig. 1～Fig. 3; The present invention is the chamber structure in a kind of motorcycle engine; Comprise cylinder liner 1 and place the piston 2 in the cylinder liner 1, be provided with cylinder head firing chamber 3 in the outside of piston 2 on the cylinder liner 1, be connected with intake valve 4 and exhaust valve 5 on the cylinder head firing chamber 3 respectively; Bottom near piston 2 one sides on the cylinder head firing chamber 3 is provided with hemispherical dimples 31, and the top near cylinder head firing chamber 3 one sides on the piston 2 is provided with piston crater 21.
Chamber structure in this motorcycle engine is through being provided with hemispherical dimples 31 and piston crater 21 respectively in cylinder head firing chamber 3 and 2 in piston; In the firing chamber of forming by cylinder head firing chamber 3 and piston 2 and intake valve 4 and exhaust valve 5, be separated out a firing chamber; And two pits are formed the firing chamber and are not hedged off from the outer world; Thereby in the power stroke of motor, in two firing chambers, produce siphonage, make burning mixture can get in the main firing chamber more rapidly; Burn fully, thereby reach higher work done power.
As the preferred embodiment of the present invention, the bottom near cylinder head firing chamber 3 one sides on intake valve 4 and the exhaust valve 5 is provided with valve pit 6, is provided with valve slot to make way 23 in the side near cylinder head firing chamber 3 on the piston 2.
As the preferred embodiment of the present invention, be provided with piston ring 22 between the inwall of the outer ring of piston 2 and cylinder liner 1, the outside of cylinder head firing chamber 3 is provided with cylinder end seal circle 33.
As the preferred embodiment of the present invention, 2 in the bottom of cylinder head firing chamber 3 and piston are provided with the gap.
Intake valve 4 can get into respectively in movement process in the valve slot to make way 23 that is provided with on the cylinder head firing chamber 3 with exhaust valve 5; Thereby by the piston crater 21 at valve pit 6 on intake valve 4 and the exhaust valve 5 and piston 2 tops, form an auxiliary combustion chamber with piston ring 22 and cylinder end seal circle 33; Form main firing chamber by the hemispherical dimples 31 of 3 bottoms, cylinder head firing chamber and the piston crater 21 at piston 2 tops; 2 gaps that are provided with of the bottom of cylinder head firing chamber 3 and piston make motor in expansion space stroke between two firing chambers the stroke siphonage, thereby can make inflammable mixture get into the firing chamber more rapidly.
In the suction stroke of motor, piston 2 is descending, and intake valve 4 is opened; The volume of firing chamber is expanded rapidly; Because the siphonage between two firing chambers, the entering that burning mixture can quicken also is full of whole firing chamber, helps in power stroke, effectively to improve its work done power; And effectively raise the utilization ratio of fuel, reduced fuel consume.
Certainly; The invention is not limited to above-mentioned mode of execution; Those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of spirit of the present invention, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
