Abstract
The utility model discloses a high pressure fuel distribution pipe of a gasoline engine used for a non-straight engine, which comprises a plurality of tubular fuel distribution pipe components; each fuel distribution pipe component is provided with an oil injector seat and a fixing support block, wherein one fuel distribution pipe component is provided with a fuel inlet; the plurality of fuel distribution pipe components are connected by a high pressure connecting pipe; the two fuel distribution pipes are communicated with a cavity in the high pressure connecting pipe; and fuel can flow into the cavity from the fuel inlet and then flows out of the oil injector seat of each fuel distribution pipe component. By adopting the high pressure connecting pipe to connect the plurality of fuel distribution pipe components, only one high-pressure oil pump and one oil pressure sensor are needed in the non-straight engine, thereby greatly lowering the cost, leading to no difference of the fuel oil pressure, and ensuring the stability of engine power output.
Description
Technical field
The utility model relates to a kind of fuel dispensing tube, especially a kind of gasoline engine high pressure fuel distribution pipe that is used for non-straight engine.
Background technique
Motor car engine all has a plurality of cylinders now, and gasoline burns after flowing into each cylinder by fuel dispensing tube, makes engine output.Spread pattern classification according to engine cylinder, now, the most frequently used motor car engine is straight engine and V-type engine, and straight engine generally is applied to the fewer motor of number of cylinders, and V-type engine can be applied to the more motor of number of cylinders.In recent years, for the very many motors of number of cylinders, in the time of generally more than or equal to 12 cylinders, motor also can adopt the W type, and for the less motor of number of cylinders, also had the manufacturer that it is modified into pancake engine.
In addition, along with development of technology, also develop recently and a kind of novel high compression engine, gasoline has very big pressure in inflow engine.This motor is compared with motor before, can export bigger power, and makes the combustion efficiency of fuel higher.But, owing to this motor need pressurize to fuel, so on the engine fuel distribution piping, just need to install the sensor of high pressure oil pump and detection oil pressure.For straight engine, because its cylinder is that equidirectional " one " word arranges, the valve of all cylinders all is arranged on the top of cylinder, therefore can adopt a fuel dispensing tube to give each cylinder fuel feeding.But for the motor of other type, its valve can not be arranged point-blank, therefore just needs many fuel dispensing tubes to give each cylinder fuel feeding.Like this, each fuel dispensing tube all needs to be provided with high pressure oil pump and oil pressure sensor, complex structure not only, and the cost costliness, and also the pressure in each fuel dispensing tube also may have difference in the course of the work, thus influence the stability that engine power is exported.
The model utility content
Technical problem to be solved in the utility model provides a kind of gasoline engine high pressure fuel distribution pipe that is used for non-straight engine, can adopt comparatively simple structure and cheap cost, for various non-straight engines provide fuel oil, and the oil pressure unanimity of the assurance fuel oil that provides.
For solving the problems of the technologies described above, the technological scheme that the utility model is used for the gasoline engine high pressure fuel distribution pipe of non-straight engine is, the fuel dispensing tube assembly that comprises a plurality of tubuloses, each fuel dispensing tube assembly all is provided with oil injector seat and the fixing piece of supporting, one of them fuel dispensing tube assembly is provided with filler opening, described a plurality of fuel dispensing tube assembly is connected by a high pressure connecting tube, the cavity of described two fuel dispensing tubes and described high pressure connecting tube inside is communicated with, fuel oil can flow into cavity from described filler opening, and the oil injector seat from each fuel dispensing tube assembly flows out then.
The utility model connects a plurality of fuel dispensing tube assemblies by adopting the high pressure connecting tube, making only needs to adopt a high pressure oil pump and oil pressure sensor in the non-straight engine, greatly reduce cost, and make the fuel oil oil pressure without any difference, guaranteed the stability of engine power output.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Accompanying drawing is the structural representation that the utility model is used for the gasoline engine high pressure fuel distribution pipe of non-straight engine.
Reference character is among the figure, 1. the fuel dispensing tube assembly; 2. fuel dispensing tube assembly; 3. oil injector seat; 4. the fixing piece of supporting; 5. filler opening; 6. high pressure connecting tube; 7. sensor connector; 8. high-pressure oil pipe joint.
Embodiment
The utility model discloses a kind of gasoline engine high pressure fuel distribution pipe that is used for non-straight engine, the fuel dispensing tube assembly that comprises a plurality of tubuloses, each fuel dispensing tube assembly all is provided with oil injector seat and the fixing piece of supporting, one of them fuel dispensing tube assembly is provided with filler opening, described a plurality of fuel dispensing tube assembly is connected by a high pressure connecting tube, the cavity of described two fuel dispensing tubes and described high pressure connecting tube inside is communicated with, fuel oil can flow into cavity from described filler opening, and the oil injector seat from each fuel dispensing tube assembly flows out then.
Gasoline engine high pressure fuel distribution pipe shown in the drawings can be used for the V6 motor, it comprises two fuel dispensing tube assemblies 1 and 2, each fuel dispensing tube assembly all is provided with oil injector seat 3 and the fixing piece 4 of supporting, oil injector seat 3 is used to install oil sprayer, carry fuel oil to cylinder, on each fuel dispensing tube assembly shown in the drawings 3 oil injector seats are arranged respectively, with 6 cylinders of corresponding V6 motor, fixing support piece 4 is used for high pressure fuel distribution pipe is fixed on motor.Fuel dispensing tube assembly 1 is provided with filler opening 5.Fuel dispensing tube assembly 1 and 2 interconnects by high pressure connecting tube 6, and fuel oil is driven from filler opening 5 by high pressure oil pump and flows into, and the oil sprayer of installing from 6 oil injector seats flows out afterwards.As shown in drawings, also be provided with sensor connector 7 on the fuel dispensing tube assembly 1, be used for installing oil pressure sensor.Described filler opening 5 adopts the high-pressure oil pipe joint, and described fuel dispensing tube assembly 1 also is connected with described high pressure connecting tube 6 by high-pressure oil pipe joint 8 with 2.
For the W12 motor, its cylinder is divided into 4 row, can adopt the high pressure connecting tube to connect 4 fuel dispensing tube assemblies, and is corresponding with the cylinder of every row.For pancake engine, its valve is arranged on the both sides of motor, therefore can respectively the fuel dispensing tube assembly be arranged on the both sides of motor, and fuel oil also is connected two fuel dispensing tube assemblies by the high pressure connecting tube.
In sum, the utility model connects a plurality of fuel dispensing tube assemblies by adopting the high pressure connecting tube, making only needs to adopt a high pressure oil pump and oil pressure sensor in the non-straight engine, greatly reduce cost, and make the fuel oil oil pressure without any difference, guaranteed the stabilizing member of engine power output.
