Abstract
The invention discloses a kind of stability solution of internal combustion engine cylinder deactivation oil-break, it is characterised in that：When internal combustion engine is in the working condition of cylinder deactivation oil-break, the valve for the cylinder that internal combustion engine is stopped by valve control element is opened, and be allowed to be in opening all the time, so, stress of the cylinder to bent axle is reduced, changing the respective amplitudes vector of bent axle simple harmonic oscillation does not influence the stability of internal combustion engine.Compared with prior art, internal combustion engine is simple in construction without being redesigned, with low cost, this power-saving technology of internal combustion engine cylinder deactivation oil-break is generalizable.
Description
Technical field
The invention belongs to technical field of internal combustion engines, more particularly to the stability solution in internal combustion engine cylinder deactivation oil-break technical field.
Background technology
The fuel ratio of internal combustion engine consumption is up to 60%, and its power-saving technology research and development application has important economic and social benefit.In many power-saving technologies of internal combustion engine, the energy-saving effect of cylinder deactivation oil-break (variable displacement) technology is the most notable.At present, the cylinder deactivation oil-break technology of domestic and international application is all to use to close cylinder control, that is, internal combustion engine, when middle low power is run, partial cylinders fuel cut-off, valve is closed all the time.In this application for closing cylinder control cylinder deactivation oil-break technology, its in-cylinder pressure of the cylinder being stopped is changed so that the Relative Vibration vector of bent axle simple harmonic oscillation is varied widely, gasoline engine vibration aggravation, noise becomes big, works long hours and is likely to result in system destruction.
People take round trip flight wheel construction or crankshaft counterbalance structure to solve the stability after internal combustion engine cylinder deactivation oil-break, and these technologies make the complexity that Structure of Internal-Combustion Engine becomes, and increasing combustion engine weight is not only reduction of matter work(ratio, meanwhile, cost is very high.
Can the stability of internal combustion engine cylinder deactivation oil-break is solved with an acceptable cost performance of people turns into the deciding factor that cylinder deactivation oil-break technology is applied.
The content of the invention
The present invention provides the stability solution of internal combustion engine cylinder deactivation oil-break a kind of simple in construction, with low cost.
In order to solve the above-mentioned technical problem there is provided a kind of stability solution of internal combustion engine cylinder deactivation oil-break by the present invention, it is characterised in that：When internal combustion engine is in cylinder deactivation oil-break working condition, under program, the valve for the cylinder that internal combustion engine is stopped by valve control element is opened, and be allowed to be in opening all the time, so, active force of the cylinder to bent axle is reduced, changing the respective amplitudes vector of bent axle simple harmonic oscillation does not influence the stability of internal combustion engine.
It is preferred that described solution coordinates adjustment idling for internal combustion engine rotating speed, the idle stability when present invention can make idle stability of the internal combustion engine when cylinder deactivation oil-break works with internal combustion engine normal work is in same level.
The present invention is compared with prior art, simple in construction, with low cost and do not change internal combustion engine existing structure, this power-saving technology of internal combustion engine cylinder deactivation oil-break is generalizable.

Embodiment 4：
In Fig. 4; pressing plate 13 is installed on rocker arm support and pressing plate 13 is located at the top position of valve rocker 3; when valve rocker 3 pushes valve guide 8; produce gap between valve guide 8 and pressing plate 13; with Fig. 1; motor 12 is under the control of programme-control 6, and motor 12 drives swing arm 11 to be located at position between valve rocker 3 and pressing plate 13, and valve does not reach closed position so as in opening shape.
By the specific implementation of the invention described above, then coordinate idling for internal combustion engine rotating speed, by experiment, internal combustion engine is taken after cylinder deactivation oil-break, its idle stability and the idle stability of internal combustion engine normal work are in same level.
From the specific implementation of foregoing invention, the application is compared with existing crankshaft counterbalance technical scheme and free wheels technical scheme, and internal combustion engine is simple in construction without being redesigned, it is with low cost, this power-saving technology of internal combustion engine cylinder deactivation oil-break is generalizable.
Presently preferred embodiments of the present invention is the foregoing is only, the present invention, all any modification, equivalent substitution and improvements done within the principle of the present invention etc. is not intended to limit, should be included within the scope of protection of the invention.
