Abstract
The utility model relates to a fuel feeder for an engine, which comprises a fuel pump on a fuel inlet passage between a nozzle of the engine and a fuel tank. The utility model is characterized in that a fuel passable between the nozzle and the fuel pump is connected with a one-way valve; the fuel pump is connected with a pressure relief channel in parallel after connected with the one-way valve in series. The utility model has the advantages of simple structure, convenient assemblage, low price, reliable operation, etc. with the adoption of the utility model, the effect of the atomization of fuel can be improved, and the fuel can be sufficiently combusted; the electric energy and the fuel is saved, and the operating efficiency of the engine can be improved.
Description
The utility model relates to a kind of main auxiliary products of motor car engine, and particularly a kind of motor car engine is for the oil supplying device of Fuel System.
At present, to be the negative pressure that produces by the to-and-fro motion of engine cylinder inner carrier sucks the firing chamber internal combustion to fuel oil for engine operation to the motor car engine oil supply system from Carburetor, and this fuel system exists the fuel delivery instability, the fuel-oil atmozation granularity is big, burning is insufficient, discharge amount of exhaust gas big and waste deficiency such as fuel oil.In order to address these problems, relevant technologies personnel are provided with an oil pump and are connected in series with it on the oil-feed path fuel oil stabilizer, though it can provide enough oil pressure for engine nozzle, but, because the peak injection pressure of engine nozzle is less than the delivery pressure of oil pump, cause the oil pressure in the oil-feed path between oil pump and the nozzle to increase gradually, the pressure of nozzle ejection fuel oil also constantly increases, the nozzle ejection amount of fuel plays pendulum, influenced the mixing ratio of atomizing effect and the fuel oil and the air of fuel oil, it is abundant not enough to burn, and has wasted fuel oil; Also there is following deficiency in this oil supplying device, when the oil pressure in the oil-feed path between oil pump and the nozzle increases to delivery pressure with oil pump and is more or less the same, the motor speed of oil pump is slowed down even stall, can waste electric energy too greatly because of the electric current of Oil pump electrical machinery like this, and Yin Wendu is too high for a long time and burn out motor easily.
The purpose of this utility model just provides a kind of oil-feeding device for engine of simple in structure, reliable and oil pump working stability, and it can provide stable injection pressure for engine nozzle.
The purpose of this utility model is to realize by such technological scheme, it includes the nozzle that is connected motor and the oil pump on the oil-feed path between the fuel tank, it is characterized in that: be connected with one-way valve on the oil-feed path between nozzle and the oil pump, oil pump and one-way valve series connection back are in parallel with the pressure release passage of band Decompression valves.
Working principle of the present utility model is such: oil pump will be extracted out in the fuel from fuel tank by the oil-feed path, enter the nozzle of motor, the combustion chambers burn work done that enters motor after the mist of oil of nozzle ejection and the air mixing through one-way valve, oil-feed path with constant oil pressure.When the oil pressure in the oil-feed path between one-way valve and the nozzle was higher than specified value, Decompression valves was opened automatically, and fuel oil enters fuel tank or oil pump input end through pressure release passage, Decompression valves; When the oil pressure in the oil-feed path between one-way valve and the nozzle was lower than specified value, Decompression valves cut out automatically; Like this, guarantee to enter the engine nozzle oil pressure constant in, guaranteed that also Oil pump electrical machinery with normal stabilization of speed work, has prolonged the working life of product.
Owing to adopted technique scheme, the utlity model has following advantage:
1. simple in structure, easy to assembly, low price;
2. because the jet pressure of engine nozzle is constant, fuel pressure in the oil-feed path can enter in the fuel tank by pressure release passage when too high, so the machine operation of oil pump is stable, not fragile, both save electric energy, guaranteed the stable output of nozzle ejection amount of fuel again;
3. because fuel oil is magnetized, therefore improved the atomizing effect of fuel oil, the mixing ratio of fuel oil and air is uniform and stable, makes fuel oil be able to abundant burning, has reduced discharge amount of exhaust gas, and energy saving has improved efficiency of engine;
4. cancel Carburetor, greatly reduced oil consumption.
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1. nozzle; 2. oil-feed path; 3. oil pump; 4. one-way valve; 5. Decompression valves; 6. pressure release passage; 7. fuel magnetizer.
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model includes the nozzle 1 that is connected motor and the oil pump 3 on the oil-feed path 2 between the fuel tank, it is characterized in that: be connected with one-way valve 4 on the oil-feed path 2 between nozzle 1 and the oil pump 3, oil pump 3 and one-way valve 4 series connection backs are in parallel with the pressure release passage 6 of band Decompression valves 5.
Working principle of the present utility model is such: oil pump 3 will be extracted out in the fuel from fuel tank by oil-feed path 2, enter the nozzle 1 of motor, the combustion chambers burn work done that enters motor after the mist of oil of nozzle 1 ejection and the air mixing through one-way valve 4, oil-feed path 2 with constant oil pressure.When the oil pressure in the oil-feed path 2 between one-way valve 4 and the nozzle 1 was higher than specified value, Decompression valves 5 was opened automatically, and fuel oil enters fuel tank or oil pump 3 input ends through pressure release passage 6, Decompression valves 5; When the oil pressure in the oil-feed path 2 between one-way valve 4 and the nozzle 1 was lower than specified value, Decompression valves 5 cut out automatically; Like this, guarantee to enter engine nozzle 1 oil pressure constant in, guaranteed that also Oil pump electrical machinery with normal stabilization of speed work, has prolonged the working life of product.
As shown in Figure 1, magnetized in order to make fuel oil, oil-feed path 2 is provided with fuel magnetizer 7, and fuel magnetizer 7 is the both sides that two blocks of permanent magnets are arranged on oil-feed path 2 in the relative mode of opposite pole; Nozzle 1 is through magnetized metallic nozzle.Fuel oil is through the said apparatus back magnetization, make fuel oil be magnetized into orderly short molecular chain by original mixed and disorderly long molecular chain, particle is thinner, enlarge the surface of contact of fuel oil and air, improve the atomizing effect of fuel oil, fuel oil and air mixing are even, make fuel oil be able to abundant burning, reduce toxic emission, save the energy.
