Description
Technical field
The present invention relates to the engine fuel supply system, be specifically related to the system of a kind of shape of a saddle gasoline fuel tank to engine oil.
Background technique
At present, the tank design of " shape of a saddle " is more and more general, fluid in order to ensure major and minor fuel tank part in saddle-shaped oil tank all can participate in engine fuel system, in a lot of designs, all can utilize siphon principle that the fuel oil in drop tank is drawn in main fuel tank.
At notice of authorization number: US6,871,640B2, the applying date: in U.S.'s patent of invention of on March 18th, 2003, denomination of invention " SADDLE TANK SIPHON PRIMER ", utilize fuel pump simultaneously to siphon mechanism (pick-up) fuel feeding in motor and drop tank, the recycling syphon tube is communicated with siphon mechanism and main fuel tank, and the fluid in drop tank is sucked to main fuel tank.But, in this invention, at first, between fuel pump and siphon mechanism, need oil pipe to be connected, this has just improved structure complexity; Secondly, in this patent of invention, at the oil outlet end of fuel pump, be provided with a threeway, one end is to engine oil, and an end output is as the power of the Jet injector to the drop tank oil suction, and fuel pump is motor and siphon mechanism fuel feeding simultaneously, that is to say, motor and Jet injector share an output.If regard motor and Jet injector as two loads, two loads change: along with the difference of engine speed, the use amount of its fluid is also different, this certainly will have influence on the input of Jet injector, this has just caused fuel oil to enter before motor and has just produced oil pressure loss and unstable, may cause engine oil not enough and affect working efficiency and engine life.In addition, during the situations such as vehicle voltage is low when existing, fuel pump natural wastage, the input of the power of Jet injector also will obviously diminish, even not enough.Therefore, this invention can cause the situation of syphon structure oil suction deficiency in fuel tank.
In notice of authorization number: CN1075160C, the applying date: on August 6th, 1996, denomination of invention " are supplied the fuel oil supply device of fuel oil " by reservoir to combustion engine Chinese invention patent in Motor Vehicle, oil pump (oil feeding mechanism) be first by fuel delivery to internal-combustion engine, then unnecessary fluid oil return is to oil tank bottom, and then the mixed zone oil suction of the siphon structure by oil tank bottom.This device does not need for fuel pump increases oil pipe, and still, this device need to arrange a mixed zone, still has complex structure, problem that cost is high, and still there is the problem of and jet pump simultaneously voltage supply injection system fitted for gasoline simultaneously in oil feeding mechanism.
Above invention is all the siphon stress problems of simultaneously having considered gasoline, diesel oil, but due to gasoline and diesel oil aspect the physical propertys such as viscosity factor, exist many different, and along with the application of direct fuel-injection engine is more and more general, gasoline also can enter high pressure oil rail after the high pressure oil pump pressurization again, so, for petrolic oil supply system, also have further room for improvement.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, oil supply system that cost is low, make fluid in the drop tank in saddle-shaped oil tank stably by siphon, to enter main fuel tank and participate in engine oil.
For achieving the above object, the invention provides following technological scheme:
A kind of shape of a saddle gasoline fuel tank oil supply system comprises: the gasoline fuel tank, and the one side is main fuel tank, opposite side is drop tank; Fuel pump, it is arranged in described main fuel tank and by the gasoline in described main fuel tank and flows to motor; Siphon mechanism, it is arranged in described drop tank; Syphon tube, the one end is communicated with described siphon mechanism, and the other end is communicated with described main fuel tank, thereby the gasoline in described drop tank is delivered to described main fuel tank; Also comprise return tube, described return tube one end is communicated with the high pressure oil rail of described motor, and the other end is communicated with described siphon mechanism.
Preferably, between described high pressure oil rail and described siphon mechanism, pressure regulator valve also is installed, described pressure regulator valve guarantees to reach in described high pressure oil rail the pressure of setting.
Preferably, be provided with main fuel-quantity transducer in described main fuel tank, be provided with secondary fuel-quantity transducer in described drop tank.
Preferably, described fuel pump is positioned at the main lubricating cup of described main fuel tank.
Preferably, described main lubricating cup has filtration.
Beneficial effect of the present invention is:
Fuel pump of the present invention is only engine oil, without oil pressure, lose, and between fuel pump and drop tank without without independent oil pipe, simple in structure, siphon mechanism utilizes the oil return in high pressure oil rail that pressure is provided, and high pressure oil rail itself has played the power source effect of jet pump, saved cost, and, for gasoline, the pressure of high pressure oil rail oil return generally is enough to provide siphon mechanism required pressure, and oil pressure is stable.
Further, between high pressure oil rail and siphon-pump, pressure regulator valve is installed, while only having pressure in high pressure oil rail to be greater than setup pressure value, pressure regulator valve is just opened, opening degree can determine according to the size that surpasses setting value, and that is to say, pressure regulator valve had both played the effect of voltage stabilizing, play again the effect of preferential assurance high pressure oil rail oil pressure, avoided return line to cause the oil pressure loss.
Further, fuel pump is positioned at main lubricating cup, can guarantee liquid level height.
Further, filtration can guarantee that fluid is clean.
The accompanying drawing explanation
Next in connection with accompanying drawing, specific embodiments of the invention are described in further detail, wherein:
Fig. 1 is the structural representation of the oil supply system of embodiments of the invention.
Description of symbols in upper figure: gasoline fuel tank 100, main fuel tank 110, drop tank 120, ridge 130, main lubricating cup 140, fuel pump 200, transport pipe 300, return tube 400, pressure regulator valve 500, siphon mechanism 600, syphon tube 700, main fuel-quantity transducer 800, secondary fuel-quantity transducer 900.
