Abstract
The utility model discloses an assembled pressure sensor of an engine comprising an engine, an inlet manifold and a pressure sensor, wherein the inlet end of the inlet manifold is communicated with the outside, and the outlet end thereof is communicated with a combustion chamber of the engine; and the assembled pressure sensor is characterized in that an air pressure conduit is arranged between the inlet manifold and the pressure sensor, one end of the air pressure conduit is fixed on the inlet manifold and close to the engine, and the other end thereof is provided with the pressure sensor. The assembled pressure sensor of the engine has the obvious benefits of absorbing the vibration effectively, reducing the pollution of oil fouling on water vapor, isolating high-temperature heating, prolonging the service life the pressure sensor and lowering the maintenance cost of the sensor.
Description
Technical field
The utility model belongs to engine electric spray system, is specifically related to the installation combination of pressure transducer in a kind of automobile and motorcycle electronic fuel injection engine.
Background technique
Pressure transducer is one of component important in the engine electric spray system, is used for the suction pressure of detection of engine.Usually pressure transducer is directly installed on the outlet side of engine intake manifold in traditional electric injection system, when negative pressure sucks motor with air, can clearly detects the size of the indoor negative pressure of engine combustion by pressure transducer.
The available engine pressure transducer is installed the shortcoming of combination: under traditional mounting type, pressure transducer directly is fixed on the intake manifold, can produce vibration when engine operation, can affect to the use of pressure transducer; Simultaneously, because pressure transducer is too near apart from motor, when the engine long time service, heating produces high temperature easily, has a strong impact on the working life of pressure transducer; In addition, the greasy dirt that motor produces, and the water vapour of intake manifold suction etc., all can cause ill effect to pressure transducer, greatly the working life of the pressure transducer of Suo Duaning, increased maintenance and the cost that upgrades pressure transducer.
The model utility content
The purpose of this utility model provides a kind ofly can effectively isolate high temperature, and the engine pressure sensor of protection pressure transducer is installed combination.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of engine pressure sensor is installed combination, be provided with motor, intake manifold and pressure transducer, the inlet end of described intake manifold communicates with the external world, the outlet side communicates with described engine chamber, its key is: also be provided with pressure catheter, an end of this pressure catheter is fixed on the described intake manifold and near described motor, the other end of this pressure catheter is equipped with pressure transducer.
Described pressure catheter is a rubber pipe.
For ease of rubber pipe is installed.Have through hole on the intake manifold wall, be drilled with screw thread on the through-hole wall and connecting tube is installed, connecting tube and through-hole wall joint are coated with sealer, and it is smooth to stay the outer connecting tube outer wall of intake manifold, and rubber pipe is fixed on the plain tube through anchor ear.
Carry the rubber pipe conduit on the pressure transducer, rubber pipe is fixed on the rubber pipe conduit through anchor ear.
Because rubber pipe is a flexible material, the vibration that brings in the time of can effectively slowing down engine operation; In addition, pressure transducer is connected with intake manifold by rubber pipe, prolonged the path of gas arrival pressure transducer, make greasy dirt in the gas and water vapour before arriving pressure transducer attached to rubber pipe on, only need clean or change rubber pipe during cleaning, effectively prolonged the working life of pressure transducer, reduced because of maintenance or the replacing cost that pressure transducer brought.
Described pressure transducer is installed on the vehicle frame.
Because pressure transducer is not directly installed on motor next door, but at interval a segment distance, effectively isolated the high temperature that the motor heating produces, prolonged the working life of pressure transducer, reduced because of maintenance or changed the cost that pressure transducer brought.
Remarkable result of the present utility model is: effectively slow down vibration, reduce greasy dirt and water vapour and pollute, isolate heating high temperature, prolong the working life of pressure transducer, reduced the sensor maintenance expense.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of engine pressure sensor is installed combination, be provided with motor 1, intake manifold 2 and pressure transducer 4, the inlet end of described intake manifold 2 communicates with the external world, the outlet side communicates with described motor 1 firing chamber, be provided with pressure catheter 3 between described intake manifold 2 and pressure transducer 4, an end of this pressure catheter 3 is fixed on the described intake manifold 2 and near described motor 1, the other end of this pressure catheter 3 is equipped with pressure transducer 4.
Described pressure catheter 3 is a rubber pipe.
Described pressure transducer 4 is installed on the vehicle frame 5.
Although above structure is described preferred embodiment of the present utility model in conjunction with the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite of the utility model aim and claim; can make multiple similar expression; as change the fit of intake manifold 2 and pressure catheter 3; change pressure transducer 4 and pressure catheter 3 fit; and the mounting point of change pressure transducer 4 on vehicle body, such conversion all falls within the protection domain of the present utility model.
