Shown in Fig. 2 and 7, the outlet (not shown) of the control valve 162 of OCV 120 by be formed on path 153 in the cylinder head 6 (left side group 7a) with rocker shaft 27 (exhaust side) thus oil circuit 27a be connected oil pressure be applied to adjustable valve door system 17a with the shortest path.The oil circuit 26a of rocker shaft 26 is connected with return path 153a (only being presented among Fig. 7) in being formed on cylinder head 6.
As shown in Figure 2, the outlet of the control valve 182 of OCV 121 is connected with the oil circuit 26b (right group 7b) of air inlet side rocker shaft 26 by the path 6b in the cylinder head 6 that is formed on right group 7b.Path 6b is defined as oil circuit in the present invention.As shown in Figure 2, the discharging unit for discharging of the control valve 182 of OCV 121 through with about the phantastron parts 155 that are connected with 7b of group 7a be connected with the oil circuit 26b that the rocker shaft 26 (air inlet side) of 7a is organized on a left side, inlet 156a is positioned at the end of cylinder head 6 (left side group 7a), and path 156 is connected with inlet 156a.
With this structure, when control valve 182 (oil controlling valve door 121) is operated, about being applied to from accumulator 183, oil pressure organizes adjustable valve door system 17a and the 17b of 7a and 7b, the running of organizing 7a and 7b is switched to fast mode from normal mode.When control valve 162 (OCV 120) is operated, oil pressure is applied to adjustable valve door system 17a from the driven oil pump 170 of camshaft, and the running of left side group 7a will switch to the cylinder park mode that left side group 7a stops.
With this structure, air inlet side switching mechanism 69a and 79a and exhaust side switching mechanism 97 can be done switching according to the running state of automobile (traffic tool) by variable valve device between operating mode.
In this embodiment, motor fuselage 1, adjustable valve door system 17a, adjustable valve door system 17b, OCV120 and OCV 121 form the variable valve device 300 that is defined as first cross part in the present invention.
Behavior with reference to Figure 11 and 14 explanation adjustable valve door systems 17.When the running state according to automobile, when the order that is used to carry out low-speed mode was provided to control unit 122, control unit 122 made the control valve 162 and 182 of OCV 120 and 121 keep closing.
Just, oil pressure is taken action among 26b and the 27a not at oil circuit 26a.Shown in the solid line among Figure 11, the window 44 of the handover operation parts 40a (air inlet) of left side group 7a is blocked by piston 46 (by the elastic force of pressure spring 47).The window 50 of handover operation parts 40b (air inlet) is opened (by the elastic force of pressure spring 54), shown in the solid line of Figure 12.
As shown in figure 13, the window 100 of the handover operation parts 98 (exhaust) of left side group 7a is blocked by piston 102 (by the elastic force of pressure spring 103).Then, in the group 7a of a left side, air inlet side cam follows rocking bar 60 (low speed) and exhaust side cams is followed rocking bar 80 close pistons 46 and 102 ground wave.
Therefore, in the group 7a of a left side, the displacement of intake cam 33 (being used for low speed) is sent to the rod end of air intake valve 13a and 13b from valve driving rocking bar 35 by rocker arm 37, thereby drives air intake valve 13a and 13b.The displacement of exhaust cam 32 also is sent to the rod end of drain tap 15a and 15b from the link arm 95 of valve driving rocking bar 90 by arm 93, thereby drives drain tap 15a and 15b.
In the air inlet side of right side group 7b, similar left side group 7a, the displacement that only is sent to the low speed intake cam (not shown) of valve driving rocking bar 35 is sent to the air intake valve (not shown), thereby drives air intake valve.At exhaust side, the displacement of exhaust cam (not shown) is directly transferred to drain tap by valve driving rocking bar 90, thereby drives drain tap.
Therefore, group 7a and 7b are operated (up to predetermined engine speed range: run well) about under the low-speed mode that the combination of the Lower speed cam of Figure 19 and exhaust cam brings.
When motor became high engine speed range above the desired speed scope owing to the operation of the acceleration that for example requires high output, control unit 122 was only opened the control valve 182 of the OCV 121 that is used for fast mode.This make savings in accumulator 183 high oil pressure or come the high oil pressure of the lubricating pump that free crank output drives with high rotating speed to be introduced to the oil circuit 26b of left side group 7a and the oil circuit 26b (air inlet side rocker shaft) of right group 7b by pipe component 155 and path 156.
Therefore, switch on the pin 55 of (air inlet side) handover operation parts 40b that needed oil pressure is applied to left side group 7a or right group 7b.Like this, the piston 53 that is upwards driven by pin 55 has blocked window 50, shown in 1 long 2 short-terms of Figure 12.Then, shown in 1 long 2 short-terms of Figure 12, about the air inlet side cam of group 7a and 7b follow rocking bar 70 and waved on being close to piston 53 time.
Because it is big that the profile of high speed intake cam 30 is set than low speed intake cam 33, only the displacement of following the intake cam 30 (being used at a high speed) of rocking bar 70 from cam is sent to air intake valve 13a and 13b from valve driving rocking bar 35.Just, the air intake valve 13a of group 7a and 7b and 13b are only driven by high speed intake cam 30 about.
The displacement of exhaust cam 32 is followed the link arm 95 that rocking bar 80 is sent to valve driving rocking bar 90 from cam, thereby continues to drive drain tap 15a and the 15b of left side group 7a.The drain tap of right group 7b keeps moving with same action.Therefore, group 7a and 7b switch to the fast mode that the combination by the High speed cam of Figure 19 and exhaust cam brings about.
When automobile enters the running state that fuel consumption reduces, for example, low speed and middling speed operation or neutral gear, control unit 122 carries out cylinder park mode (being used to reduce the pattern of fuel consumption).Just, control unit 122 is opened the control of the control valve 162 of the OCV 120 that is used for the cylinder park mode.
In this point, because being used for the rotation (double crank shaft) of oil pump 170 by camshaft 25 that is attached on the OCV 120 of cylinder park mode is driven, even under low engine speed state (even neutral gear), in other words, even do not guarantee oil pressure in accumulator 172a, the oil pressure that is enough to drive the switching of adjustable valve door system 17a also is guaranteed.
As shown in Figure 2, the oil pressure of oil pump 170 is provided to path 153 by the open-close port of control valve 162, and this guides to oil pressure the oil circuit 27a of rocker shaft 27 (exhaust side).Then, the oil pressure of oil circuit 27a is introduced to the oil circuit 26a of the rocker shaft 26 (air inlet side) among the group 7a of a left side, and this raises the piston 46 of each handover operation parts 40a.
Therefore, the window 44 of air inlet side handover operation parts 40a is opened.Because oil pressure is not taken action on handover operation parts 40b, window 50 be opened (referring to Figure 12).
Therefore, in the group 7a of a left side, cam follow rocking bar 60 (air inlet: low speed) and cam follow rocking bar 80 (exhaust) and when impinging air, waved.This has interrupted being used to drive the transmission of the driving force of valve to valve driving rocking bar 35 and 90 (air inlet and exhaust).
In this point, in the air inlet variable valve device 20 and exhaust variable valve device 21 of right side group 7b, the displacement of intake cam is sent to air intake valve constantly and the displacement of exhaust cam is sent to drain tap constantly.Because this reason, motor switch to the cylinder park mode that left side group 7a is suspended.
Because in service at the cylinder park mode, the scope of cylinder park mode has been widened by the driven oil pump 170 of camshaft, and the frequency of cylinder park mode is increased.Therefore, the chance of maintenance that comprises the OCV 120 of oil pump 170 is increased.
The following describes maintenance.The maintenance of supposing OCV 120 and oil pump 170 is carried out.OCV 120 and oil pump 170 all are attached to the outer surface of motor fuselage 1.
Because this reason, in a single day R is opened when engine compartment, comprises that the whole OCV 120 of oil pump 170 is presented among the engine compartment R.This satisfied the motor fuselage outer side to present OCV 120 and oil pump 170 safeguard.
Therefore, can safeguard control valve 162 and oil pump 170 and do not need the work of part of the dismounting motor fuselage 1 of trouble.
In addition, OCV 120 and oil pump 170 are attached to the cylinder head end (being arranged in the motor body parts in the engine compartment R top) that is arranged in as obvious and nearly hand position, therefore, can easily safeguard in OCV 120 and oil pump 170.
Particularly, oil pump 170 is provided in the shell 163 of OCV 120, and this makes oil pump 170 near control valve 162 (switching part).Therefore, oil pressure can be given to adjustable valve door system 17a effectively and reduce the loss.In addition, oil pump 170 has constituted the part of OCV 120, and therefore, the simplification of oil pump 170 is implemented.
In V-type engine, when OCV 120 and oil pump 170 were set in the outer wall surface at cylinder head end place of the group 7a that carries out the cylinder park mode, by utilizing the characteristics of V-type engine, OCV 120 and oil pump 170 were arranged in the position of nearly hand.This has realized maintaining easily of OCV 120 and oil pump 170.
Particularly, when the left side group 7a of attached OCV 120 laterally is installed in the engine compartment, left side group 7a is arranged on automotive body distolateral (embodiment's front side).As a result, OCV 120 and oil pump 170 can clearly be identified when safeguarding at once.OCV 120 and oil pump 170 also are arranged on the position of nearest hand.This has given OCV 120 and oil pump 170 high maintenance attributes.
Similarly, to be arranged on automotive body in the motor distolateral vertically installing when OCV 120 and oil pump 170, and the convenience of maintenance also can be modified.When OCV 120 and oil pump 170 are arranged on the automotive body front side, the convenience of maintenance is further improved.
Have only by about the OCV 121 that generally uses among group 7a and the 7b just can switch to fast mode, this makes the switching between fast mode and the cylinder park mode can only pass through minimum OCV, that is, the OCV 120 and 121 that is arranged in respectively among group 7a and the 7b carries out.
Therefore, the quantity of expensive OCV can be reduced, and therefore, motor cost and engine weight can be reduced.
Because OCV 120 and 121 is arranged in the group skew Space L 1 and L2 that becomes V-type engine inner cap space, OCV 120 and 121 can be assembled to motor compactly.Therefore, can suppress the size increase of motor.
In addition, the OCV 120 that is used for the cylinder park mode is not arranged on the outer surface that is arranged on the group end in the group, therefore, carries out safeguarding (because not needing to dismantle the outer surface that different parts is exposed to OCV 120 group) OCV 120 easily.
Particularly, compare with OCV 121, the OCV 120 that is used for the cylinder park mode is arranged on automotive body distolateral (embodiment's automotive body front side), is installed in attitude in the engine compartment irrelevant (laterally or the motor of vertically installing) with motor.Therefore, in maintenance, the ratio OCV 121 that is used for the cylinder park mode has the OCV 120 of high maintenance frequency more to be positioned at the position of obvious and nearly hand, maintain attribute height.According to present embodiment, the OCV 120 that is used for the cylinder park mode is arranged in the automotive body front side, and this has further improved the convenience of safeguarding.
The present invention is not only limited to described embodiment, and numerous variations and modification can not exceeded scope of the present invention by generation.
Though adjustable valve train uses piston structure to switch to the cylinder park mode among the embodiment, as an example, the adjustable valve train that switches to the cylinder park mode in addition may be used.
