Abstract
The utility model relates to a multitube stepped air inlet pipe for a single-cylinder diesel engine, the big choke pipe of which is arranged in the main air inlet pipe. One end of the main air inlet pipe is connected with a flange and the other end is connected with an air filter. The casing of the compensating air inlet valve is provided with a valve and a valve spring, and the air-in joint of the valve is connected with the air filter through a rubber hose and the air-out joint is connected with the compensating air inlet pipe through a rubber hose. The small chock pipe is arranged in the compensating air inlet pipe and the compensating air inlet pipe is connected with a flange. When the diesel engine works in a low rotary speed and under a light load, the compensating air pipe closes automatically and only the main air inlet pipe supplies air, and when the diesel engine transits to a high rotary speed and a heavy load, the valve of the compensating air pipe opens gradually and supplies air. When under the operating mode of a high rotary speed and a heavy load, the main air inlet pipe and the compensating air inlet pipe supply air simultaneously, thereby the air supply is abundant, the combustion is sufficient, the power is improved and the pollution discharging and the oil consumption are reduced.
Description
Technical field:
The utility model relates to a kind of single cylinder diesel multitube classification suction tude, and it is applicable to single cylinder and multi-cylinder diesel engine, can be installed in new and old diesel engine, belongs to the technical field of diesel engine.
Background technique:
Traditional diesel engine intake pipe, its internal diameter and air inflow are changeless, can not be adapted to the inflation requirement under the various operating modes, especially by the little load of the slow-speed of revolution when the big load transition of high rotating speed, because the variation of air feed does not catch up with the retardation phenomenon of load variations and over-emitting black exhaust, increase blowdown, the air feed deficiency also makes incomplete combustion, and oil consumption increases.
Summary of the invention:
The utility model is will solve the diesel engine intake pipe can supply the air inlet classification according to the needs of operating mode, supplies with sufficient air inflow according to the variation of diesel engine speed and load, makes sufficient combustion, reduces blowdown, improves its power, reduces its oil consumption.
Structure of the present utility model is, pack into the internal diameter of main suction tude of big trunnion, main suction tude one end is connected with flange, the other end is connected with air-strainer, in the valve housing of subsidy suction tude shutter spring and valve are housed, the valve air input joint is connected with air-strainer with sebific duct, and air outlet adapter also is connected with the subsidy suction tude with sebific duct, small venturi is also packed into and is subsidized in the internal diameter of suction tude, and the subsidy suction tude is connected with flange again.
The advantage of multitube classification suction tude is can be according to the variation of rotating speed, load, and the ample supply air quantity can reduce blowdown, improves power, saves oil consumption, has both applied to new diesel engine, also can be installed on old diesel engine.
Description of drawings:
Fig. 1 multitube classification suction tude schematic representation
By Fig. 1, pack into the internal diameter of main suction tude (1) of big trunnion (2), main suction tude (1) one end is connected with flange (3), the other end is connected with air-strainer, in the subsidy suction tude valve housing (4) shutter spring (5) and valve (6) are housed, valve air input joint (7) is connected (this filter cleaner does not draw among the figure) with sebific duct (8) with air-strainer, valve air outlet adapter (9) also uses sebific duct (10) to be connected with subsidy suction tude (11), small venturi (2) is packed into and is subsidized the internal diameter of suction tude (11), and subsidy suction tude (11) is connected with flange (3).
Embodiment:
When diesel engine under the situation of the little load of the slow-speed of revolution, subsidy tracheae valve (6) is closed under the air-flow differential effect automatically, at this moment just by the independent air inlet of main suction tude (1), the big trunnion (2) that is provided with in the main suction tude improves intake efficiency, strengthen the air-flow coherence, obtain resonance effect, when diesel engine by the little load of the slow-speed of revolution during to the big load transition of high rotating speed, valve under the air-flow pressure action (6) is opened again gradually, make diesel engine steady, rounding off, reduced smoke intensity and rough property in the diesel engine transition, when diesel engine is in the big load condition of high rotating speed always, the just air inlet simultaneously of main suction tude (1) and subsidy suction tude (11), ensure maximum air inflow, this two suction tude is respectively equipped with big trunnion (2) and small venturi (12), has reached the quickening air velocity, improves air mass flow, therefore, fuel oil instantaneous explosive combustion in the firing chamber is complete, has improved the thermal efficiency, reduce smoke intensity, saved oil consumption.
