Description
Technical field
The purpose of this utility model provides a kind of automobile and the artificial device that is provided with of engine experimental table oil path failure.
Background technology
The automotive electronics oil supply system is one of big main system of three in the automotive electronic control system system.In current various imports in usefulness, in the middle of the domestic automobile, it is common faults type comparatively that oil supply system breaks down, the automobile assembly parts that relate to are also many, because various imports of today, the oil supply system of domestic automobile all is that employing is electronically controlled, therefore its fault diagnosis technology requires high, certain degree of difficulty is arranged, and at automobile maintenance industry, grasp comprehensively and detect at the automotive electronics oil supply system failure, diagnosis, and can carry out quantitatively oil path failure, the technician of qualitative analysis comparatively lacks, work is organized grade of skill evaluation and technical examination etc. with traffic department, also is difficult to relate to these aspects comprehensively.
On the other hand, in automotive operation and the training of service engineering vocational education, also lacking a kind ofly can provide various automotive electronics oil supply system most common failures and exceptional fault at any time, simultaneously, do not damage the device of " recurrence of failure " of automobile overall performance again, the device of this " recurrence of failure " can also be subjected to artificial control.
Summary of the invention
At the problems referred to above, the utility model provides a kind of automobile and the artificial device that is provided with of engine experimental table electronics oil supply system failure, except automobile or the original electronics oil supply system of engine experimental table, the device that adds mainly contains one section pipeline (4), a four-way (15), intercepting valve A (9), intercepting valve B (10), intercepting valve C (11) and fixed head (16) and a fuel pressure gauge (5) that is used for monitor force.Particular content is: block electronic fuel pump to the oil feed line between the fuel pressure regulator (3), intercepting valve (11) is installed, a four-way (15) is installed in front at intercepting valve, one end of four-way connects one section extra pipeline (4), the other end of this pipeline feeds fuel tank (1), and the other end of four-way is connected to the situation of change that fuel pressure gauge (5) is used to monitor fuel pressure.An intercepting valve (10) is installed on extra pipeline, an intercepting valve (9) is installed on scavenge pipe.By tuning or close intercepting valve (9), intercepting valve (10) and intercepting valve (11), just can realize simulating that oil circuit obstruction, fuel valve dribbling, fuel filter are stopped up, the fuel pressure regulator pressure regulation is too high, the fuel pressure regulator pressure regulation is low excessively, the oil pump wearing and tearing cause that charge oil pressure is low, pump pressure is crossed high polytype automobile oil supply system failure.Owing to the situation of change that has inserted fuel pressure gauge (5) supervision fuel pressure at oil inlet pipe (3), so fault setting can be controlled in the safe scope.
By above-mentioned design, the beneficial effects of the utility model are: add some simple devices in automobile or the original electronics oil supply system of engine experimental table, by changing the flow and the flow direction of fuel oil, just can artificially control the oil supply system failure that makes automobile or engine experimental table number of different types occur, offer the examination of auto repair and the training of fault diagnosis vocational education and technical ability and use.This apparatus features is simple in structure, and is with low cost, safe and reliable, convenient and swift.
Its structural principle and be connected as shown in the figure with the installation of automobile or engine experimental table:
Description of drawings
Fig. 1 is that oil path failure is provided with schematic diagram, and Fig. 2 is the installation panel figure of intercepting valve, and Fig. 3 is built-in fuel pressure regulator electronics oil supply system figure.
Among the figure:
The 1st, fuel tank
The 2nd, electronic fuel pump
The 3rd, oil inlet pipe
The 4th, the one section pipeline that adds
The 5th, external fuel pressure gauge
The 6th, the fuel injector mounting bracket
The 7th, fuel pressure regulator
The 8th, scavenge pipe
The 9th, intercepting valve A
The 10th, intercepting valve B
The 11st, intercepting valve C
12 is four fuel injectors
The 13rd, the vacuum tube interface
The 14th, oil filler
The 15th, the four-way that adds
The 16th, the fixed head of intercepting valve
The fuel pressure regulator of present most of automobiles all is installed in an end of fuel injector support, we are referred to as " external fuel pressure regulator " usually, but also have some vehicles, fuel pressure regulator is designed to become one with electronic fuel pump, be immersed in the fuel tank, we are referred to as " built-in fuel pressure regulator " usually.At the vehicle fuel feed system of " built-in fuel pressure regulator " structure, the artificial technical scheme that is provided with of its electronics oil supply system failure is provided with principle and method basically identical with the vehicle fuel feed system fault of " external fuel pressure regulator " structure.See accompanying drawing 3
Embodiment:
In the embodiment shown in fig. 1, intercepting valve A (9) and intercepting valve C (11) are in fully open position, intercepting valve B (10) is in full close position, fuel oil supply system does not change, with the same operate as normal of fuel oil supply system of former car configuration.At this moment, intercepting valve A (9) and intercepting valve C (11) are in fully open position, it is crack to adjust intercepting valve B (10), because a part of fuel oil flows back to fuel tank (1) by the one section pipeline (4) that adds, therefore the fuel injector support can not keep enough pressure, the fault that similar fuel valve dribbling, oil circuit rush down leakage occurs, observe fuel pressure gauge (5) and will find that fuel pressure is lower than normal value.The condition of this fault setting is: fuel pressure kills engine after setting up.
In second embodiment shown in Figure 1, intercepting valve C (11) is in fully open position, intercepting valve B (10) is in full close position, adjust intercepting valve A (9) to closing direction, be unlikely to again to close fully, observe fuel pressure gauge (5) and find that pressure can be higher than normal value, this is because the oil return caliber attenuates, and causes oil return not smooth, so the too high fault of similar fuel pressure regulator pressure regulation occurs.The condition that is provided with of this fault is: the engine operation also is in idling operation.
In the 3rd embodiment shown in Figure 1, intercepting valve A (9) is in fully open position, intercepting valve B (10) is in full close position, adjust intercepting valve C (11), the pressure that can find fuel pressure gauge (5) demonstration is apparently higher than normal value, this is because the in-line caliber diminishes, cause oil-feed not smooth, the fault that similar oil circuit stops up, fuel filter wears out obstruction, high type is crossed in the fuel pressure regulator pressure regulation occurs.The condition that is provided with of this fault is: engine operation, idling operation.What pay particular attention to is: this fault is set to be needed to note at any time observing the pressure that fuel pressure gauge shows, should kill engine before tensimeter indicated pressure≤6Kp, in order to avoid too high oil pipe explosion or the joint of causing of line pressure comes off.
