Gbt2820.1 requires power to be divided into cop (continuous power), prp (prime power), ltp (display runs power), esp (emergent standby
With power) four ranks, refer to Fig. 1.Although boat engine does not have Standard, also generally make according to difference in industry
It is divided into four ranks of p1, p2, p3, p4 power with, service condition.
It is all the definition that nominal power has been carried out with power rating species in current national standard, industry, company standard.
And the major defect of prior art presence is as follows:
(1) existing engine power stage division is simple, only one operating point of nominal power is defined being classified, system
Determine principle and guard the lifting just limiting engine power, radical just cannot ensure engine reliability.
(2) each power level engine maintenance maintains indifference, not strong to the directiveness of user.
Content of the invention
(1) technical problem to be solved
The technical problem to be solved in the present invention is: how to carry out engine power classification, contrasts with operating principle, and pass through
Instrument shows result, instructs user more reasonably using diesel engine；And how to be selected optimal according to the actually used situation of user
Maintaining scheme, to extend engine life.
(2) technical scheme
In order to solve above-mentioned technical problem, the present invention provides a kind of engine power stage division, calculates electromotor and runs
Strength factor in region, wherein, the computing formula of strength factor is:
μ strength factor；
T engine strokes number:
peEngine power (kw)；
N engine speed；
I number of cylinders；
vhSwept volume (the m of each cylinder3)；
S piston stroke；
Multiple power region are divided into according to the numerical values recited of strength factor, are formulated according to different power region different
Operating principle.
Wherein, by ecu, to electromotor applying working condition, affiliated power region is monitored, and counts its affiliated levels of transmission power area
The run time in domain, is contrasted with operating principle, and result is shown by monitoring device, instruct user's reasonable employment, and
Suitable maintaining scheme is selected according to electromotor applying working condition.
Wherein, described operating principle includes annual run time, average load rate requirement, peak power run time.
Wherein, described maintaining scheme includes oil exchange cycle, three filter replacement cycles, overhaul time and whole machine longevity
Life.
Wherein, mechanical pump engine installs throttle position switch, air inlet pressure is gathered by throttle position switch
Power and tach signal Positioning power region, carry out the determination of coefficient of intensification, and result are shown by instrument.
(3) beneficial effect
Compared with prior art, the invention has the advantages that
A kind of engine power stage division that the present invention provides, by calculating the intensity system in engine operation region
Number, engine power is divided into multiple power region, formulates different operating principles according to different power region, with operation
Principle contrasts, and instructs user more reasonably using diesel engine, in addition, being easy to user according to electromotor in different capacity region
Actually used situation selects optimal maintaining scheme, to extend engine life.
The shorter electromotor of high power region use time can lift peak power according to engine power stage division.
Brief description
The chart that Fig. 1 defines for generating engine power rating；
Fig. 2 is a kind of logic schematic diagram of present invention engine power stage division.
Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.Following instance
For the present invention is described, but it is not limited to the scope of the present invention.
In describing the invention, it should be noted that term " " center ", " longitudinal ", " horizontal ", " on ", D score,
The orientation of instruction such as "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outward " or position relationship are
Based on orientation shown in the drawings or position relationship, it is for only for ease of the description present invention and simplifies description, rather than instruction or dark
Show the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that right
The restriction of the present invention.
Additionally, in describing the invention, unless otherwise stated, " multiple ", " many ", " multigroup " be meant that two or
Two or more.
As shown in Fig. 2 the invention provides a kind of engine power stage division, calculating strong in engine operation region
Degree coefficient, wherein, the computing formula of strength factor is:
μ strength factor；
T engine strokes number:
peEngine power (kw)；
N engine speed；
I number of cylinders；
vhSwept volume (the m of each cylinder3)；
S piston stroke；
Multiple power region are divided into according to the numerical values recited of strength factor, taking certain displacement engine as a example, strength factor
More than 19 is p4 power, is p3 power between 17 to 19, is p2 power between 15 to 17, is p1 power less than 15；User Ke Gen
Formulate its different operating principle according to the different power region of electromotor, operating principle includes annual run time, average load
Rate requirement, peak power run time etc., thus being more reasonably classified to engine power, realize power classification by point
Develop into face, be easy to the actually used situation according to electromotor in different capacity region for the user and select optimal maintaining scheme,
To extend engine life.
Specifically, by ecu (electronic control unit), to electromotor applying working condition, affiliated power region is monitored, statistics
The run time in its affiliated levels of transmission power region, and contrast with operating principle, and result is shown by monitoring device, side
Just user intuitively observes the power region level attribute that electromotor runs at present, the annual run time allowing and remaining
Working time etc., instruct user more reasonably using electromotor, and suitable maintenance can be selected according to electromotor applying working condition
Maintenance scheme, instructs user more reasonably using diesel engine.
