Description
Technical field
The utility model relates to vehicular field, particularly, relates to a kind of engine valve actuating mechanism, motor and vehicle.
Background technique
Distribution device is motor very part and parcel, the effect of distribution device is the requirement of acting order according to each cylinder of motor and each work cycle, periodically each cylinder intake valve and exhaust valve are opened, closed, enter cylinder to make fresh mix device, gas of combustion discharges cylinder.
For petrol engine, at present, in petrolic distribution device, mostly be four valves, i.e. two intake valves, two exhaust valves, as depicted in figs. 1 and 2, this distribution device comprises the first intake valve 10, second intake valve 20, and wherein, described first intake valve 10 and the second intake valve 20 driven by all identical the first cam 11 of cam profile and phase place and the second cam 21 respectively.All identical with phase place with the cam profile of the second cam 21 just because of described first cam 11, therefore described first intake valve 10 and the second intake valve 20 are with the motion of the identical characteristics of motion, and the position that each moment opens is identical.Concrete, when valve opening, gas enters in cylinder from intake duct, with spraying fuel oil mixing after-combustion.Enter in the process of cylinder at gas, the type of flow of air-flow directly can affect the firing effect of mixed gas in cylinder, and the type of flow of air-flow is controlled by whole gas handling system and distribution device.When described first intake valve 10 moves with the identical characteristics of motion with the second intake valve 20, first intake valve 10 and the second intake valve 20 will be opened simultaneously, enter like this air-flow in firing chamber can relative to cylinder axis symmetry (this is because, in most cases, the position of described first intake valve 10 and the second intake valve 20 is relative to cylinder symmetry), and in firing chamber, under the effect of cylinder and piston face, form certain stream that rolls (to roll stream to be formed in intake process, organized air swirl around the axis perpendicular with cylinder-bore axis rotates), such airflow pattern is after combination spraying fuel oil, can mixture gas be taken near spark plug, finally burn after firing.But because in intake process, air-flow only defines and rolls stream, and (eddy current is formed in intake process not form certain eddy current, around the organized air motion of cylinder-bore axis), this just makes gas can not mix fully with spraying fuel oil, and then affects firing effect.
Model utility content
The purpose of this utility model is to provide one can make gas and the well-mixed engine valve actuating mechanism of spraying fuel oil.
The utility model also provides a kind of motor and the vehicle with good combustion efficiency.
To achieve these goals, the utility model provides a kind of engine valve actuating mechanism, this engine valve actuating mechanism comprise for same cylinder at least two intake valves and drive the cam of these at least two IO Intake Valve Opens and closedown for correspondence, cam described in each has different phase places or has different line styles, is not opening in the same time with at least two intake valves described in can driving.
Preferably, cam described in each has default phase place separately, to make having default phase difference along described cam adjacent in described cam sense of rotation.
Preferably, described default phase difference is 15 degree of-25 degree.
Preferably, cam arrangement described in each is on same camshaft.
Preferably, described engines distribution vibrational power flow is at the top of motor, thus described camshaft is overhead camshaft.
Preferably, cam described in each has different phase places and the cam profile of cam described in each is identical.
Preferably, described intake valve is two and is respectively the first intake valve and the second intake valve, and described cam is two and is respectively for driving the first cam of described first intake valve and for driving the second cam of described second intake valve.
The utility model also provides a kind of motor, and described motor comprises described engine valve actuating mechanism.
Preferably, described motor is petrol engine.
The utility model also provides a kind of vehicle, and described vehicle comprises described motor.
The distribution device that the utility model provides, having different phase places by making each cam of same cylinder or having different line styles makes the start-up time of each intake valve different, thus make the type of flow of air-flow in intake process not only only roll stream, and also have certain eddy current, and then make gas more abundant with mixing of spraying fuel oil, Optimizing Combustion effect.
Other feature and advantage of the present utility model are described in detail in embodiment part subsequently.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the noun of locality such as " upper and lower, left and right " of use typically refers to reference to upper and lower, left and right shown in the drawings; " inside and outside " refers to profile inside and outside relative to each parts itself.
According to an aspect of the present utility model, the utility model provides a kind of engine valve actuating mechanism as shown in Figure 3 and Figure 4, this engine valve actuating mechanism comprise for same cylinder at least two intake valves and drive the cam of these at least two IO Intake Valve Opens and closedown for correspondence, wherein, cam described in each has different phase places or has different line styles, is not opening in the same time with at least two intake valves described in can driving.
Here it should be noted that why cam described in each has different phase places, because when cam described in each has identical phase place and identical cam profile, each intake valve that described in each, cam correspondence drives will be opened at synchronization or close, but air-flow in intake process will be made so only to define roll stream, and do not form certain eddy current, finally make gas can not mix fully with spraying fuel oil, and then affect firing effect.Otherwise, if cam described in each has different phase places or has different line styles, each intake valve that described in each, cam correspondence drives like this would not be opened at synchronization or close, Just because of this, in intake process, air-flow not only defines and rolls stream, but also define certain eddy current, and then gas can be mixed fully with spraying fuel oil.Certainly, in order to design conveniently, reduce costs, preferably, cam described in each has different phase places and the cam profile of cam described in each is identical.
Wherein, cam described in each has default phase place separately, to make having default phase difference along described cam adjacent in described cam sense of rotation.That is, can pre-set a phase place for cam described in each according to actual conditions, in order to reach good firing effect, preferably, described default phase difference is 15 degree of-25 degree.
For the ease of installing and simplifying the structure of described gas distribution structure, preferably, cam arrangement described in each is on same camshaft.
Wherein, described engine cam can be middle or underneath type, and preferably, described engine cam adopts overhead type, and that is, described engines distribution vibrational power flow is at the top of motor, thus described camshaft is overhead camshaft.
Wherein, described intake valve is two and is respectively the first intake valve 10 and the second intake valve 20, and described cam is two and is respectively for driving the first cam 11 of described first intake valve 10 and for driving the second cam 21 of described second intake valve 20.
