Herein, " standard " means that the cam curve of control air intake valve is relative to " starting " pattern of engine
It is completely constant.In addition, the concept of standard also means that the present invention keeps crack referred to as exhaust air type (bleeder with valve
Type those special applications) are unrelated.In contrast, the present invention be directed to the improvement of traditional scheme, wherein valve is in closing
When completely close.
Therefore, because of the invention, bent axle per revolution can all perform compression-decompression behavior (compression-
decompression event).Particularly, decompression behavior is performed in each TDC.
According to the preferred embodiment of the present invention, braking strategy, such as 2010 are realized by performing cam displacement method

Control flume on sleeve cooperates with a cam pin carrys out sliding axially for control sleeve, and the cam pin is by live spindle branch
Support, the live spindle tangentially contacts control flume.
The method of the present invention, which is included in, sets two or more exhaust cam curves on the adjacent part of exhaust sleeve
Step, and cause the step of sleeve is axially shifted on standard shaft, in order to make exhaust cam curve be able to carry out braking
Two decompression behaviors of journey.
According to above-mentioned paper, the concept of " adjacent part " is clear：Multiple cam curves are annularly limited to sleeve
On adjacent and continuous part and along the longitudinally extending direction of sleeve.
According to another implementation of the invention, by the three-D cam with different curves from the axle on standard shaft
2- stroke braking procedures are performed to displacement.The example of this solid cam is shown in EP0208663.
In addition, the part of the present invention is the method that axially displaced cam curve is used during engine braking.

Embodiment
According to the present invention, during brake operating, changed by least one according to cam displacement method (i.e. by
Axially shiftable sleeve on standard shaft, in order to be able to form different cam curves) exhaust cam curve realize to engine
The control of valve.
According to the preferred embodiment of the present invention, for each complete circulation, i.e. each 720 degree for bent axle, lead to
The offer of identical exhaust cam curve is provided and decompresses behavior twice, and one or more drain taps have been kept in remaining time
Contract fully, sole exception performs extra expiratory phase B-III, such as following institute by one or more drain taps
It is disclosed.
In order to be clearly understood that the present invention, during braking procedure, the first compression stage is overlapped with the standard compression stage, that is, is worked as
During engine start, during braking procedure, engine is pind down (drag) and prevents injector spray fuel.
First decompression behavior B-II ' occurs approximately in greatly TDC.Preferably, the drain tap before piston reaches TDC
Somewhat open, to discharge pressure.
According to the present invention, after the first compression behavior B-II ', drain tap is stayed open, and (this (starts) valve with standard
Door behavior is opposite), in order to allow same piston from blast pipe suction air B-III.
In the second lift stage of piston, i.e. the four-stage F-IV of 4- Stroke Engines circulation, (engine has been sent out
It is dynamic), drain tap is opened in order to evicting waste gas from.In contrast, according to the present invention, at second liter of the brake operating stage
Journey stage, drain tap is remained closed in carrying out the second compression stage, and the second compression stage is followed by the second decompression
Behavior.
As being illustrated above, " closing " refers to " completely closing ", rather than is partially turned off as in exhaust scheme.
It is clear that the admission cam lifting curve of air intake valve is relative to standard cycle, (i.e. engine, which is in, starts shape
The circulation of state) it is completely constant.
On the contrary, according to the present invention, one or more of drain taps in the second decline stage of piston, (i.e. send out by 4- strokes
The phase III B-III of motivation circulation) stay open, and (4- Stroke Engines are circulated during the second lift stage B-IV
Fourth stage) remain turned-off, this with shown in F-IV emissions standard behavior (wherein described drain tap be open with
In discharge waste gas) it is opposite.
In other words, the first expiratory phase is realized by air intake valve, therefore, and admission cam lifting curve is constant, and the
Two expiratory phases are realized by drain tap, therefore only exhaust cam lifting curve changes.
Fig. 1 show the four-stage F-I to F-IV (left side of figure) of the 4- Stroke Engines under launch state with
According to the comparison between the braking procedure (right side of figure) from B-I to B-IV of the present invention.

Part/braking condition (namely when the engine is driven and when engine is in braking mode) is identical；
F-II and B-II：The first time lift of piston；During braking procedure, suppress fuel injection and second stage B-
II includes decompression behavior B-II '；
F-III and B-III：Second of decline of piston：When the engine is driven, air intake valve and drain tap are to close
Close；When engine is in braking mode, drain tap is to open, and is sucked in order to perform second of air, but from
Exhaust side is sucked；
F-IV and B-IV：When the engine is driven, during fourth stage, waste gas is discharged by drain tap, on the contrary,
During braking procedure, the identical behavior that drain tap is referred to during following with second stage, i.e. compression stage B-IV heel
With decompression behavior B-IV '.
