Description
Technical field
The utility model belongs to petrol engine oil-saving apparatus technical field, especially relates to a kind of fuel economizer.
Background technique
Along with the development of society, demand for the energy also progressively improves, energy consumption gets more and more, the energy also more and more lacks, especially oil, the significantly raising of the recoverable amount of Motor Vehicle, for gasoline, the demand rapid growth of diesel oil, the discharge environmental pollution of tail gas is more serious simultaneously, increasing substantially of the consumption of the Motor Vehicle energy, become the difficult problem that the whole society needs to solve, thus the oil consumption reducing Motor Vehicle becomes the problem needing solution at present badly, although there are some fuel economizers at present, but due to the restriction of its structure, fuel-efficient effect is not ideal, have impact on promoting the use of of fuel economizer.
Model utility content
The purpose of this utility model be to improve the deficiency of prior art and provide a kind of and regulate the pressure balance effect of the vacuum pressure in crankcase and intake manifold, increase engine output power, reduce engine movements resistance, reduce oil consumption, structure is simple, fuel-efficient effective, fuel economizer that cost is low.
The purpose of this utility model realizes like this, a kind of fuel economizer, be made up of housing, be characterized in that housing cavity is divided into upper and lower two-part by the elastomer diaphragm be fixed in inner walls, top is ventilation chamber, lower space is divided into left and right two-part by partition wall, left side is suction chamber, right side is discharge chamber, ventilation chamber is provided with vent, suction chamber is provided with suction port, discharge chamber is provided with air outlet, tinsel is close to the elastomer diaphragm side of being installed on it, the connecting rod of tinsel is fixedly connected with spring through elastomer diaphragm, spring upper end is installed on the suction port of discharge chamber, lower end is fixed on the spring seat bottom discharge chamber.
In order to realize the purpose of this utility model further, can be, outside suction port, seal ring is installed.
Compared with the prior art the utility model has following distinguishing feature and good effect: suction port of the present utility model is connected with valve-chamber cover air outlet, air outlet is connected with intake manifold, vent air-strainer connects, elastomer diaphragm compressible spring seals the suction port of discharge chamber, the suction of intake manifold when being worked by the motor car engine be communicated with air outlet, the air inlet indoor exhaust air attracting elastomer diaphragm bottom discharge chamber and be communicated with valve-chamber cover air outlet, make valve-chamber cover, in crankcase and the suction chamber of elastomer diaphragm bottom, discharge chamber forms negative pressure, which reduces the intake stroke friction in down stroke of engine piston, play adjustment valve-chamber cover, the pressure balance effect of the vacuum pressure in crankcase and intake manifold, reach fuel-efficient object, increase engine output power, simultaneously when elastomer diaphragm bottom two Room negative pressure, under the effect of elastomer diaphragm upper and lower cavity pressure reduction and intake manifold suction, elastomer diaphragm Compress Spring seals the mouth of pipe of giving vent to anger, avoid excessive air-breathing, ensure that the normal work of motor, at valve-chamber cover, when have accumulated engine exhaust in crankcase, waste gas will enter in the suction chamber of elastomer diaphragm bottom, when suction chamber internal pressure is higher than top ventilation chamber pressure, elastomer diaphragm under the action of the spring, open the suction port of closed discharge chamber, waste gas enters discharge chamber and discharges, tinsel auxiliary pressure elastomer diaphragm, avoid elastomer diaphragm stressed comparatively large and damage, when high engine speeds works, the pressure needed in valve-chamber cover, crankcase is larger, air-strainer gettering quantity strengthens, vent chamber gas will be drawn like this and form negative pressure, elastomer diaphragm pushed open by secondary spring, avoid the excessive air-breathing of intake manifold and cause valve-chamber cover, crankcase pressure too low, affecting motor, be operated in outside suction port and seal ring is installed, make joint good seal, avoid exhaust gas leakage.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is another kind of structural representation of the present utility model.
Embodiment
Embodiment 1, a kind of fuel economizer, with reference to Fig. 1, that housing 1 inner chamber is divided into upper and lower two-part by the elastomer diaphragm 7 be fixed on housing 1 inwall, top is ventilation chamber 9, lower space is divided into left and right two-part by partition wall 10, left side is suction chamber 11, right side is discharge chamber 12, ventilation chamber 9 is provided with vent 6, suction chamber 11 is provided with suction port 2, discharge chamber 12 is provided with air outlet 5, tinsel 8 is close to elastomer diaphragm 7 side of being installed on it, the connecting rod of tinsel 8 is fixedly connected with spring 4 through elastomer diaphragm 7, spring 4 upper end is installed on the suction port of discharge chamber 12, lower end is fixed on the spring seat bottom discharge chamber 12, this forms a kind of structure of the present utility model.
Embodiment 2, a kind of fuel economizer, and with reference to Fig. 2, in order to ensure sealing effect, be provided with seal ring 3 outside suction port 2, other are identical with embodiment 1.
When using the utility model, vent 6 is communicated with the air-strainer of motor, suction port 2 is communicated with the valve-chamber cover air outlet of motor, air outlet 5 is communicated with the intake manifold of motor, during such engine operation, the intake manifold of motor draws discharge chamber 12 by air outlet 5, valve-chamber cover is drawn in the suction chamber 11 be communicated with by discharge chamber suction port and the valve-chamber cover air outlet be communicated with suction port 2, waste gas in crankcase, make valve-chamber cover, in crankcase and suction chamber, discharge chamber forms negative pressure, which reduces the intake stroke friction in down stroke of engine piston, regulate valve-chamber cover, vacuum pressure in crankcase and the pressure balance of intake manifold, reach fuel-efficient object, increase engine output power, simultaneously at suction chamber, during discharge chamber negative pressure, under the effect of elastomer diaphragm about 7 pressure reduction and intake manifold suction, elastomer diaphragm 7 Compress Spring 4 seals the suction port of discharge chamber 12, avoid excessive air-breathing, ensure that the normal work of motor, the compression of spring 4 simultaneously drives tinsel 8 descending, ensure elastomer diaphragm 7 uniform force, at valve-chamber cover, when have accumulated more engine exhaust in crankcase, waste gas will enter in suction chamber 11, when suction chamber 11 internal pressure is higher than ventilation chamber 9 pressure, elastomer diaphragm 7 is under the effect of spring 4, open the suction port of closed discharge chamber 12, when high engine speeds works, the pressure needed in valve-chamber cover, crankcase is larger, air-strainer gettering quantity strengthens, vent chamber gas will be drawn like this and form negative pressure, elastomer diaphragm 7 pushed open by secondary spring 4, avoid the excessive air-breathing of intake manifold and cause valve-chamber cover, crankcase pressure too low, affecting the high speed operation of motor.
