Abstract
The present invention provides a connector between an engine and an air inlet manifold for gasoline/LPG or gasoline/natural gas dual-fuel vehicles, including a pipe connecting piece, a pressure discharging hole, an air inlet channel and a pressure discharging ring. The present invention is characterized in that the internal side of the pipe connecting piece is provided with the air inlet channel; the rampart of the pipe connecting piece is provided with the pressure discharging hole; the external side of the pressure discharging hole is provided with a pressure discharging ring; the internal side of the pressure discharging hole is communicated with the air inlet channel. A end of the pipe connecting piece is connected with the tail end of the air inlet manifold fixed by a fastening part; The B end of the pipe connecting piece is connected with the air inlet end of the engine fixed by a fastening part. When the drawing phenomenon of the fuel vehicle engine occurs, the present invention can prevent the connector from falling and further ensure the normal operation of the fuel vehicle.
Description
Affiliated technical field
The present invention relates to a kind of gasoline/liquefied petroleum gas (LPG) or the gasoline/motor of rock gas variable fuel vehicle use and the connecting head of intake manifold.
Background technique
At present, the ordinary casing that the connecting head of known gas combustion automobile motor and intake manifold system is made by elastic material, the air inlet port of one end and motor joins, and the end of the other end and intake manifold joins, and fixes with fastening piece.But, when this connecting head tempering phenomenon occurs at the gas combustion automobile motor,, produce the problem that can cause connecting head to come off to intake manifold direction adverse current by the huge high-pressure combustion gas that engine chamber produces.General connecting head only plays the interconnect function of motor and intake manifold, when tempering phenomenon appears in motor, does not have the decompression protection function, can not guarantee the normal operation of gas combustion automobile.
Summary of the invention
For fear of the problem that the gas combustion automobile engine flashback causes connecting head to come off, the invention provides a kind of connecting head, this connecting head can make high-pressure combustion gas obtain discharging, not the problem that can cause connecting head to come off when tempering phenomenon appears in motor.
The technical solution adopted for the present invention to solve the technical problems is, an end of connecting head and the air inlet port of motor join, and the other end and intake manifold end join, and fix with fastening piece.Several relief holes are set on the ring wall of connecting head, and relief hole is inboard to communicate with gas-entered passageway, when the expansive pressure release lasso of arranged outside pressurized, pressure release lasso move at the motor nominal situation, is in air-tight state.When tempering phenomenon appearred in the gas combustion automobile motor, pressure release lasso pressurized expanded at once, and relief hole is opened, and the high-pressure combustion gas that engine flashback produces can be released from relief hole moment of connecting head.After the pressure release, the pressure release lasso shrinks at once and sets back, and the relief hole of connecting sleeve is airtight.
Of the present invention simple in structure, beneficial effect is that when tempering phenomenon appearred in the gas combustion automobile motor, the problem of avoiding connecting head to come off reached the normal purpose of moving of gas combustion automobile.
Description of drawings
Accompanying drawing 1 is a structural profile schematic representation of the present invention
Accompanying drawing 2 is a scheme of installation of the present invention
As shown in Figure 1, the ring wall place of pipe connecting piece 1 arranges relief hole 2, and the inboard of pipe connecting piece 1 is air inlet Passage 3, the inboard of relief hole 2 communicates with inlet channel 3, the arranged outside pressure release lasso of relief hole 2 4, pressure release lasso 4 is airtight with the outside of relief hole 2.
As shown in Figure 2, the port A of pipe connecting piece 1 and the end of inlet manifold J join, and be solid with securing member Fixed, other port B of pipe connecting piece 1 and the air inlet port of engine F join, and fix with securing member.
Embodiment
In Fig. 1, Fig. 2, the ring wall place of pipe connector 1 is provided with relief hole 2, and the inboard of pipe connector 1 is a gas-entered passageway 3, and the inboard of relief hole 2 communicates with gas-entered passageway 3, the arranged outside pressure release lasso 4 of relief hole 2, and pressure release lasso 4 is airtight with the outside of relief hole 2.
The port A of pipe connector 1 and the end of intake manifold J join, and fix with fastening piece, and other port B of pipe connector 1 and the air inlet port of motor F join, and fix with fastening piece.
When automobile normally moved, mixed gas was from the A extreme direction B extreme direction of pipe connector 1, and the gas-entered passageway 3 through pipe connector 1 inboard enters motor F, and pressure release lasso 4 is airtight with relief hole 2.
When tempering phenomenon appearred in motor, high-pressure combustion gas was produced from the B extreme direction A extreme direction refluence of pipe connector 1, when flowing through relief hole 2 places, pressure release lasso 4 pressurizeds expand rapidly, relief hole 2 is opened, and high-pressure combustion gas is just from gas-entered passageway 3, and release at 2 places through relief hole.After the pressure release, pressure release lasso 4 shrinks and sets back, and pressure release lasso 4 is airtight with relief hole 2.
Claims (2)
1. a gasoline/liquefied petroleum gas (LPG) or automobile/rock gas variable fuel vehicle motor and the intake manifold connecting head that joins and use, an end and intake manifold end join, and fix with firm, and the other end and engine charge port join, and fix with firm.
2. connecting head according to claim 1 is characterized in that the pipe connector ring wall is provided with several relief holes, and relief hole is inboard to communicate with gas-entered passageway, and the relief hole arranged outside has the pressure release lasso, and the pressure release lasso is subjected to compression swelling, and can shrink and set back.
