Abstract
A kind of charged piston, comprise piston mechanism, storage mechanism, control mechanism, be provided with valve rod aperture 6 in the piston 1 of described piston mechanism, piston 1 front end is provided with valve port 5, is provided with gas storage chamber 4 in the piston wall of front end, connecting rod chamber 11; The piston nose of described control mechanism is provided with valve 7, and valve stem 8 afterbody of valve 7 is provided with Returnning spring 9, rear end is provided with gland 10; The utility model utilizes piston movement to press gland unseat the valve to rear solstice and enters in the storage chamber being arranged at front end, connecting rod chamber by the high-pressure gas in work done later stage, store the high-pressure gas in work done later stage; During employing suction stroke, piston movement presses to rear solstice the air that gland unseat the valve releases the high-pressure gas pressurization suction stored, and makes to obtain higher compression ratio in cylinder, makes full use of power character and the Economy of combustion gas high pressure raising motor.
Description
Technical field
The utility model relates to supercharging technology in engine cylinder, specifically a kind of charged piston.
Background technique
Stronger according to Motor Vehicle firing chamber compressive force, outputting power and the larger working principle of outburst dynamics, the motor of same displacement, compression ratio is higher, its power character and Economy better.Utilize the external pressurized turbosupercharger of tail gas energy obtain universal and promote, but its pressurized effect exists hysteresis quality, preparation complexity costly for this reason.
Model utility content
The utility model, for the problems referred to above, provides a kind of charged piston, supercharging in the high-pressure gas utilizing the work done later stage.
According to the technical solution of the utility model: a kind of charged piston, comprise piston mechanism, storage mechanism, control mechanism.
Connecting rod chamber 11 is provided with in the piston 1 of described piston mechanism, both sides, connecting rod chamber 11 are provided with connecting rod pin-and-hole 2, valve rod aperture 6, piston 1 front end is provided with valve port 5, and piston 1 outer wall is provided with piston ring groove 3, is provided with storage mechanism in the forward bolt piston wall of connecting rod chamber 11.
Described storage mechanism is provided with gas storage chamber 4.
The piston nose of described control mechanism is provided with valve 7, and valve stem 8 afterbody of valve 7 is provided with Returnning spring 9, rear end is provided with gland 10.
Technique effect of the present utility model is: adopt and be arranged at storage chamber in the forward bolt piston wall of connecting rod chamber and move to rear solstice by fuel work doing pistons and press gland unseat the valve and enter by the high-pressure gas in work done later stage, store the high-pressure gas in work done later stage; During employing suction stroke, piston movement presses to rear solstice the air that gland unseat the valve releases the high-pressure gas pressurization suction stored, and obtains higher compression ratio, makes full use of power character and the Economy of high-pressure gas raising motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is plan view of the present utility model.
Fig. 3 is the utility model worm's eye view.
Embodiment
Below in conjunction with accompanying drawing, the embodiment in the utility model is described further.
In Fig. 1, Fig. 2, Fig. 3, comprise piston 1, connecting rod pin-and-hole 2, piston ring groove 3, gas storage chamber 4, valve port 5, valve rod aperture 6, valve 7, valve stem 8, Returnning spring 9, gland 10, connecting rod chamber 11 etc.
According to a kind of charged piston of the utility model, comprise piston mechanism, storage mechanism, control mechanism.
Described piston mechanism comprises piston 1, connecting rod chamber 11, connecting rod pin-and-hole 2, valve rod aperture 6, valve port 5, piston ring groove 3; Connecting rod chamber 11 is arranged in the rear side of piston 1; Valve rod aperture and front valve rod aperture after valve rod aperture 6 points; Connecting rod pin-and-hole 2, rear valve rod aperture 6 are arranged in the skirt section of both sides, connecting rod chamber 11, and front valve rod aperture 6 is arranged at the front side of gas storage chamber 4; Valve port 5 is arranged in the front-end face of piston 1, and piston ring groove 3 is arranged on the outer wall of piston 1.
The gas storage chamber 4 of described storage mechanism is arranged in the piston wall of front end, connecting rod chamber 11.
Described control mechanism comprises valve 7, valve stem 8, Returnning spring 9, gland 10; Valve 7 is arranged in valve port 5, and the valve stem 8 of valve 7 is arranged in valve rod aperture 6, and Returnning spring 9 is arranged at the rear portion of valve stem 8, and gland 10 is connected with the tail end of valve 7.
The utility model adopts fuel work doing pistons to move to rear solstice and presses gland unseat the valve and enter in the storage chamber be arranged in the forward bolt piston wall of connecting rod chamber by the high-pressure gas in work done later stage, stores the high-pressure gas in work done later stage; When utilizing suction stroke, piston movement presses gland unseat the valve to rear solstice and releases the high-pressure gas stored, and makes to obtain higher compression ratio in cylinder, makes full use of power character and Economy that high-pressure gas improves motor.
