Abstract
The utility model discloses high pressure fuel pipe arrangement structure for car, including the oil pump seat, high pressure oil pump and high pressure fuel pipe, the oil pump seat is connected in engine cylinder lid one side, the installation face of oil pump seat is located the engine cylinder lid outside, high pressure fuel pump installs on the installation face of oil pump seat, the oil pipe interface of high pressure fuel pump and high pressure fuel pipe butt joint is towards the engine cylinder lid outside, high pressure fuel pipe one end and high pressure fuel pump's oil pipe interface connection, high pressure fuel pipe extends to the oil inlet of cylinder along the engine cylinder lid outer fringe after round high pressure fuel pump one side outer fringe. The utility model discloses arrange high pressure fuel pipe's the form adjustment for arranging outside the engine cylinder lid, replace high-pressure oil pump backplate, reduce cost with arranging of high pressure fuel pipe self simultaneously.
Description
Technical Field
The utility model relates to the technical field of engines, in particular to automobile is with engine outer high pressure oil pipe arrangement structure.
Background
The high-pressure oil pipe of the existing engine is arranged to be arranged inwards around the rear part of the engine, as shown in fig. 1, the high-pressure oil pipe is arranged to pass into a cylinder cover, and meanwhile, a high-pressure oil pump protective plate needs to be added at the edge position of the high-pressure oil pump to protect the high-pressure oil pump. The prior art has the following defects: high pressure fuel pipe 1 walks around to in the cylinder cap 4, leads to not being convenient for dismantle cylinder cap 4 in the maintenance dismantlement in-process, if dismantle cylinder cap 4 again after dismantling high pressure fuel pipe 1, then the high pressure fuel pipe 1 of reassembling need carry out leak detection, leak detection need use dedicated check out test set, detect with high costsly. In addition, because oil pipe local arrangement is in high-pressure oil pump inboard, need assemble high-pressure oil pump backplate 3, protects high-pressure oil pump 2. The breather pipe is required to adopt a non-detachable connection mode according to the six emission standards of China, when the high-pressure oil pipe is arranged on the inner side of the cylinder cover to cause the disassembly of the high-pressure oil pipe, the space between a tool and the breather pipe is insufficient, the phenomenon that the tool and the breather pipe interfere when the high-pressure oil pipe is disassembled is caused, and the high-pressure oil pipe is difficult to disassemble.
Disclosure of Invention
The utility model aims at the defect that above-mentioned prior art exists, provide a high pressure fuel pipe arrangement structure for car, adjust high pressure fuel pipe's the form of arranging to arranging outside the engine cylinder lid, replace high-pressure oil pump backplate, reduce cost with arranging of high pressure fuel pipe self simultaneously.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the high-pressure oil pipe arrangement structure for the automobile comprises an oil pump seat, a high-pressure oil pump and a high-pressure oil pipe, wherein the oil pump seat is connected to one side of an engine cylinder cover, an installation surface of the oil pump seat is located on the outer side of the engine cylinder cover, the high-pressure oil pump is installed on the installation surface of the oil pump seat, an oil pipe interface of the high-pressure oil pump, which is in butt joint with the high-pressure oil pipe, faces the outer side of the engine cylinder cover, one end of the high-pressure oil pipe is connected with the oil pipe interface of the high-pressure.
The utility model discloses a further technical scheme is: the minimum distance between the high-pressure oil pipe and the high-pressure oil pump is larger than 3 mm.
The utility model discloses high pressure fuel pipe arrangement structure for car has following beneficial effect: the utility model discloses high pressure fuel pipe arranges to the engine cylinder lid outside and can provide wider space, avoids appearing the phenomenon that dismouting in-process high pressure fuel pipe and instrument interfere, and high pressure fuel pipe arranges, plays the effect of protection high pressure fuel pump round high pressure fuel pump outer fringe simultaneously, can cancel this part of high pressure fuel pump backplate, reduce cost.
The following describes the high-pressure oil pipe layout structure for a vehicle with reference to the accompanying drawings and embodiments.

FIG. 1 is a schematic illustration of a prior art high pressure fuel line disposed on an engine cylinder head;
FIG. 2 is a schematic structural view of the high-pressure oil pipe arrangement structure for the automobile of the present invention;
FIG. 3 is another directional view of FIG. 2;
the reference numbers illustrate: 1-high-pressure oil pipe, 2-high-pressure oil pump, 3-high-pressure oil pump guard plate, 4-cylinder cover, 5-oil pump seat, 6-mounting surface and 7-oil pipe interface.
Detailed Description
As shown in fig. 2 and fig. 3, the utility model discloses high-pressure oil pipe arrangement structure for car, including oil pump seat 5, high-pressure oil pump 2 and high-pressure oil pipe 1. The oil pump seat 5 is connected on one side of the engine cylinder head 4, the mounting surface 6 of the oil pump seat 5 is positioned on the outer side of the engine cylinder head 4, the high-pressure oil pump 2 is mounted on the mounting surface 6 of the oil pump seat 5, and the high-pressure oil pump 2 cannot extend into the engine cylinder head 4 (namely does not extend to the outer surface of the cylinder head and does not influence the disassembly of the cylinder head) after being mounted. An oil pipe interface 7 of the high-pressure oil pump 2 and the high-pressure oil pipe 1 in butt joint faces the outer side of the engine cylinder cover 4, one end of the high-pressure oil pipe 1 is connected with the oil pipe interface 7 of the high-pressure oil pump 2, the high-pressure oil pipe 1 extends to an oil inlet of the cylinder along the outer edge of the engine cylinder cover 4 after surrounding the outer edge of one side of the high-pressure oil pump 2, and a protective plate does not need to be. The minimum distance between the high-pressure oil pipe 1 and the high-pressure oil pump 2 is larger than 3mm, and interference is not easy to occur.
When the engine cylinder cover is disassembled and assembled, the high-pressure oil pipe does not extend to the outer surface of the engine cylinder cover, so that the high-pressure oil pipe does not need to be disassembled; meanwhile, when the high-pressure oil pipe is arranged on the outer side of the cylinder cover and the high-pressure oil pipe is detached, the space is sufficient, and the tool cannot interfere with the vent pipe.
The above embodiments are only preferred embodiments of the present invention, the structure of the present invention is not limited to the forms illustrated in the above embodiments, and any modifications, equivalent substitutions and the like made within the spirit and principle of the present invention should be included within the scope of the present invention.
