Description
Technical field
The present invention relates to locomotive technology field, and in particular to a kind of diesel engine of locomotive underrun part cylinder deactivation controlling party
Method.
Background technology
The diesel engine of railway shunting diesel locomotive or small operating diesel locomotive is typically all chronically at underrun shape
State, the diesel engine under this state, its charging efficiency also can be very low, and oil atomizing is bad, and these can cause fuel oil to burn
It is insufficient, cause cylinder fire power face, fuel injector, air valve, piston ring, blast pipe and booster inside long-pending oil carbon distribution serious, be harmful to
Emission is high, so as to have a strong impact on the reliability of diesel engine, with maintenance cost and environment.In the prior art, it is slow
Long-pending oil carbon distribution problem caused by solving diesel engine of locomotive underrun, the method typically taken are that diesel engine carbon distribution part is carried out
Periodically open and inspect, cleaning replacement, or periodically lifting diesel engine speed and load, removed using combustion high temperature caused by high load capacity
Long-pending oil carbon distribution.It is short that this way opens and inspect the replacement cycle, and maintenance cost is high, it is impossible to improves low speed operation hazardous emission problem, no
Possess intelligent, it is necessary to which manual fixed cycle operator, the requirement to operator is higher, and takes diesel engine normal working hours.
For many years, in diesel engine of vehicle technical field, for the saving fuel oil under underrun state, occur one
A little parts cylinder deactivation control program, its Basic practice is the fuel delivery that a part of cylinder is cut off when diesel engine underload works.
Such as the way of No. 87215817 Chinese patent applications is to install control gaseous mixture in the inlet manifold after carburetor to enter
Air valve, closes the air valve of certain cylinder, that is, stops the cylinder work done；The way of No. 92226188 Chinese patent applications be by magnetic valve and
Pipeline realizes cylinder deactivation, but these are required for the hardware design transformation of complexity, and is unable to reach good control effect.With
The development of electronic technology, 2006100129874 and No. 2011103589527 Chinese patent applications have further attempted to electric spray type bavin
The cylinder deactivation control technology of oil machine, but be all the main monitoring parameter using the rotating speed of diesel engine as cylinder deactivation, this can not just ensure
The entering part cylinder deactivation work mode under real low load condition.These other schemes still need carries out hardware to engine
Transformation, and it is neither possible to pointedly solving the problems, such as the long-pending oil carbon distribution and hazardous emission of diesel engine of locomotive at low load.
The content of the invention
The purpose of the present invention is exactly to overcome the deficiency of above-mentioned prior art, there is provided a kind of diesel engine of locomotive underrun portion
Divide cylinder deactivation control method.
The technical solution adopted in the present invention is a kind of diesel engine of locomotive underrun part cylinder deactivation control method, to adopt
With EFI fuel system, it is characterised in that take the following steps：
A., cylinder deactivation action condition, low oil mass setting value and high oil mass setting value are set；
B. whether detection diesel engine meets cylinder deactivation action condition：Otherwise original place is circulated；It is then to enter next step；
C. whether detection fuel delivery is less than low oil mass setting value：Otherwise return to step B；It is then to enter next step；
D. entering part cylinder deactivation operational mode, the EFI fuel feeding of stop section cylinder；
E. whether detection fuel delivery is more than high oil mass setting value, otherwise return to step D；It is then to enter next step；
F. part cylinder deactivation operational mode is exited, recovers the normal EFI fuel feeding to all cylinders；
G. return to step B.
In order to be better achieved the purpose of the present invention, the part deactivation mode in step D compiles all cylinders of diesel engine
For different operations/cylinder deactivation combination, alternately run successively by setting time or working cycles number between each combination.
The beneficial effects of the invention are as follows：In diesel engine of locomotive underrun, improve combustion position, reduce carbon distribution, subtract
Few noxious emission, saving fuel oil, improves the reliability of diesel engine of locomotive, extends maintenance period.

Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in invention, those of ordinary skill in the art exist
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Referring to Fig. 1, the diesel engine of locomotive of the present embodiment takes EFI fuel system, and control fuel injection unit 1 drives
The opening time of fuel injection pump solenoid 4 is gathered while dynamic fuel injection pump solenoid 4, is scaled fuel feed amount to judge diesel engine
Payload, at low load the fuel injection pump solenoid 4 of stop section cylinder power, reach cylinder deactivation effect.
To ensure that diesel engine carries out part cylinder deactivation in the state of rationally, cylinder deactivation action condition is set：
