Abstract
The utility model relates to a safe pressure relief electric spray engine oil supply system, which is composed of two oil tube loops. Another oil tube is positioned between an oil inlet tube and a return oil tube, which is provide a pressure relief valve, forming the second oil tube loop composed by a oil tank, a electric fuel pump, a fuel filtrator and the pressure relief valve. Usually the pressure valve is in closed state, the second oil tube loop is blocked. When the oil supply system has a failure, needing overhauling, and the pressure valve is opened, making the second oil tube loop communicating, and making the fuel inside the tube returning to the oil tank, thus discharging the pressure from the tube, realizing the effects of effectively preventing fuel spraying and safe overhauling.
Description
Affiliated technical field
The utility model relates to a kind of oil supply system of motor car engine, but especially a kind of electronic fuel injection engine oil supply system of safe unloading pressure.
Background technique
At present, known automotive electric injection engine oil supply system is to connect fuel tank, electric fuel punp, fuel filter, oil pressure regulator etc. by metal oil conduit to constitute, and has only a loop.Generally, when the electronic fuel injection engine oil supply system breaks down when overhauling, because the electronic fuel injection engine fuel pressure is higher, at first to lay down oil pressure, careless slightly in the operating process, will cause the fuel oil splash to be overflowed, both caused waste, and initiation fire very easily, bigger loss caused.At present this also there is not highly effective solution.
Summary of the invention
The problem that causes the outer spray of fuel oil when carrying out troubleshooting because of the pipe internal pressure in order to overcome existing electronic fuel injection engine oil supply system, but the utility model provides a kind of electronic fuel injection engine oil supply system of safe unloading pressure.This oil supply system can be laid down the oil pressure in the oil pipe fast, effectively prevents the fuel oil splash, and easy to operate, for troubleshooting provides safety guarantee.
The technological scheme that the utility model adopted is: engine fuel system is made of two oil pipe loops; Promptly installing an oil pipe additional on the return tube (2) between oil inlet pipe (8) between oil supply system fuel filter (6) and oil pressure regulator (4) and oil pressure regulator (4) and the fuel tank (1) is connected, the centre is equipped with pressure-relief valve (3), formation is by fuel tank (1), oil inlet pipe (8), electric fuel punp (7), fuel filter (6), pressure-relief valve (3), the second oil pipe loop that return tube (2) links to each other, pressure-relief valve under the normal condition (3) is a closed condition, second oil pipe loop obturation, when oil supply system breaks down the needs maintenance, open pressure-relief valve (3), second oil pipe loop is linked up, make the interior fuel oil of pipe pass back into fuel tank rapidly, lay down the pipe internal pressure, reach the purpose that effectively prevents fuel oil splash and safety inspection.
The beneficial effects of the utility model are: release fast and safely, effectively prevent the fuel oil splash, and cut the waste, for carrying out troubleshooting, engine fuel system provides safety guarantee.
Description of drawings
The utility model is described in further detail with mode of execution below in conjunction with accompanying drawing;
Accompanying drawing is a structural principle schematic representation of the present utility model;
Among the figure, 1. fuel tank, 2. return tube, 3. pressure-relief valve, 4. oil pressure regulator, 5. fuel dispensing tube, 6. fuel filter, 7. electric fuel punp, 8. oil inlet pipe.
Embodiment
In the accompanying drawings, but the electronic fuel injection engine oil supply system of safe unloading pressure is made of two oil pipe loops, installing an oil pipe additional on the return tube (2) between oil inlet pipe (8) between fuel filter (6) and oil pressure regulator (4) and oil pressure regulator (4) and the fuel tank (1) is connected, the centre is equipped with pressure-relief valve (3), thereby form by fuel tank (1), oil inlet pipe (8), electric fuel punp (7), fuel filter (6), pressure-relief valve (3), the second oil pipe loop that return tube (2) connects and composes, pressure-relief valve under the normal condition (3) is a closed condition, second oil pipe loop obturation, when oil supply system breaks down the needs maintenance, open pressure-relief valve (3), second oil pipe loop is linked up, make the interior fuel oil of pipe pass back into fuel tank (1) rapidly, lay down the pipe internal pressure, reach the purpose that effectively prevents fuel oil splash and safety inspection.
Claims (2)
1. but the electronic fuel injection engine oil supply system of a safe unloading pressure, it is characterized in that adopting two oil pipe loops, install an oil pipe additional on the return tube (2) between oil inlet pipe (8) between oil supply system fuel filter (6) and oil pressure regulator (4) and oil pressure regulator (4) and the fuel tank (1) and be connected, constitute the second oil pipe loop that links to each other by fuel tank (1), oil inlet pipe (8), electric fuel punp (7), fuel filter (6), pressure-relief valve (3), return tube (2).
2. electronic fuel injection engine oil supply system according to claim 1 is characterized in that in the middle of the second oil pipe loop pressure-relief valve (3) being installed.
