In addition, the structure of present embodiment also comprises oil sprayer 16 is arranged on the top that is connected between cylinder head 6 and the intake manifold 10, above oil sprayer 16, be provided with transport pipe 18, and the space of opening wide 20 that produces by means of the downward extension of the arm 14 of intake manifold 10; Among described unlimited space 20, between oil sprayer 16, transport pipe 18 and pressure stabilizer 12, be provided with engine control parts 24.
In addition, as shown in Figure 2, described motor 2 be installed in vehicle component 42 below, below will be described.
In addition, as illustrated in fig. 1 and 2, oil sprayer 16 is arranged on the top that is connected between cylinder head 6 and the intake manifold 10, is provided with transport pipe 18 above oil sprayer 16.
In addition, shown in Fig. 3 and 4, described intake manifold 10 has such structure, for example, so that the pressure stabilizer of integrative-structure 12 is connected on the cylinder head 6 by four arms 14; As shown in Figure 3, the end of arm 14 is connected on the base of pressure stabilizer 12, and arm 14 extends downwards from this tie point, is being bent near cylinder block 4 place's arms 4; Arm is along the direction setting of cylinder block 6 to cylinder head 6 after the bending, and arm 14 is just in the certain degree of the front of cylinder head 6 bending, and they are connected on the cylinder head 6 then.
In this embodiment, because the structure of the arm of above-mentioned intake manifold 10, so form a unlimited space 20 on top around this arm 14, shown in Fig. 3 and 4.
In addition, the height that described engine control parts 24 are arranged is lower than the peak of transport pipe 18 and pressure stabilizer 12, as shown in Figure 1.
In addition, described engine components 24 are connected on the intake manifold 10, and itself and pressure stabilizer 12 are structures of one.Yet when pressure stabilizer 12 and intake manifold 10 are the branch body structure, described engine components 24 can be connected on the described pressure stabilizer 12.
In addition, described engine components 24 comprise a pressure regulator control valve 26 and jar case purge control valve 28.
In this embodiment, as illustrated in fig. 1 and 2, pressure regulator control valve 26 is set, and jar case purge control valve 28 is set near pressure stabilizer 12 near transport pipe 18.
When the installation finished at motor 2 described in the vehicle (not shown), the position of the peak of transport pipe 18 and pressure stabilizer 12 is higher than the cylinder head cover 8 of motor 2, as shown in Figure 1.
In addition, label 30 is represented pvc pipe, and it connects the cylinder head cover 8 of described motor 2 and the pressure stabilizer 12 of described intake manifold 10; Label 32 is represented a vacuum tube, and arm 14 and transport pipe 18 that it connects intake manifold 10 also connect pressure regulator control valve 26; Label 34 representative pressure regulator control valves 26 regulator control valves connect support; On behalf of jar case purge control valve 28 purge control valves, label 36 connect support; The connecting tube part of the described transport pipe 18 of label 38 representatives; Label 40 representative pressure regulators; Label 42 representatives are positioned at the vehicle component of described motor top; And C represents the gyration center of bent axle (not shown).
Below operation will be described.
Along with intake manifold 10 connection to the cylinder head 6 of described motor 2, oil sprayer 16 is arranged on the top that is connected between cylinder head 6 and the intake manifold 10, above oil sprayer 16, be provided with transport pipe 18.
In addition, the layout of the decline of the arm 14 by described intake manifold 10 forms a space 20 of opening wide, and in the zone 20 in the middle of oil sprayer 16, transport pipe 18 and pressure stabilizer 12, the support 34 of pressure regulator control valve is provided with pressure regulator control valve 26 and is connected support 36 with purge control valve and is provided with a jar case purge control valve 28.
Here as additional reference, the work of pressure regulator 40 will be explained.The constant high-caliber fuel pressure with respect to pressure in the intake manifold in transport pipe 18 and the oil sprayer 16 is controlled and remained on to pressure regulator 40.When transport pipe 18 intermediate fuel oil pressure are lower than certain level,, as shown in Figure 5, and will close transport pipe 18 and fuel flow returns system with the valve body of closing pressure regulator 40.When fuel pressure was higher than certain level, the valve body of pressure regulator 40 as shown in Figure 6, was opened to the passage of transport pipe 18 and fuel flow returns system with the pressure of antagonistic spring, so discharged too high pressure.
Here will explain the work of described pressure regulator 40.Under normal condition, when pressure regulator control valve (indicated as P/R-VSV) 26 is in the closed position, the intake manifold valve body is worked in the diaphragm chamber of pressure regulator 40, and will remain on constant level in the pressure difference between transport pipe 18 and the intake manifold 10.When starting under high-temperature, pressure regulator control valve 26 will be opened and the diaphragm chamber of pressure regulator 40 will be exposed in the unlimited air, like this with the adjusting pressure of boost pressure regulator 40 and the pressure of transport pipe 18.
In addition, the steam that produces in the transport pipe 18 will be suppressed at, to improve starting performance at high temperature.
By this measure, the open spaces 20 that forms is arranged in decline by the arm of described intake manifold 10, and by using at oil sprayer 16, zone 20 between transport pipe 18 and the pressure stabilizer 12, can in described open spaces, be provided with and arrange engine control parts and pipeline, with from intake manifold 10, different parts can be arranged on minimum as far as possible position, described intake manifold 10 is connected to the top of the cylinder head 6 on the motor 2 that tilts to install, the installation dimension at motor 2 tops will be compact as much as possible, and guarantee in the top section of motor 2 and the open spaces between the vehicle component 42, cause practical advantage.
In addition, by described oil sprayer 16 being arranged on the top of the part that connects cylinder head 6 and intake manifold 10, and by transport pipe 18 being arranged on the top, position of described oil sprayer 16, to oil sprayer 16 and transport pipe 18 to be connected process efficiency higher, so improved the efficient of overall connection operation.
In addition, the structure of described intake manifold 10 is bases that the end of arm 14 is connected to pressure stabilizer 12, and arm 14 extends downwards from this tie point, is being bent near cylinder block 4 place's arms 4; Arm extends to the direction of cylinder head 6 along cylinder block 6 after bending, and just in the front of cylinder head 6 arm 14 crooked certain degree, they are connected on the cylinder head 6 then.By this structure, owing to the downward layout of the arm 14 of above-mentioned intake manifold 10 forms a unlimited space 20, help overall compact design, guarantee the enough length of arm 14 and the torque characteristics of the enhancing in middle lower speed range simultaneously; In addition, by along the just in time specific bending before being connected to cylinder head 6, to set up one and flow,, will increase air inlet and burning so cause when flowing into motor, producing the effect of rolling so that flow slowlyer simultaneously along inward flange along the outward edge flows faster.
In addition, the height of arranging by described engine control parts 24 is lower than the peak of transport pipe 18 and pressure stabilizer 12, can guarantee the opening between engine control parts 24 and vehicle component 42 clearly.
In addition, be connected on the intake manifold 10 by described engine components 24, itself and pressure stabilizer 12 are structures of one, widget can be connected on the big parts, be that engine control parts 24 are connected on the intake manifold 10, cause a modular design, it has the real advantage that increases assembling and transfer efficiency.
When the installation finished at motor 2 described in the vehicle (not shown), the position of the peak of transport pipe 18 and pressure stabilizer 12 is higher than the cylinder head cover 8 of motor 2, so the center of gravity of vehicle descends, helps to increase the Security of vehicle.
