Background technology
Engine load spectrum is the statistics of engine load parameter under assignment of mission, usage and use condition, to start
The later stage optimizes performance to machine in actual application, reaches energy-saving, provides accurate foundation.
Engine load spectrum is usually made of its Performance Parameters (such as engine speed, rate of load condensate), concentrated expression
Engine thermic load in use and mechanical load.Engine complete machine loading spectrum is the main of engine because of the object of its statistics
Running parameter, it can reflect the relative status of engine totality stand under load.Engine load spectrum is the load of engine performance research
Foundation.By the research of loading spectrum, the status information of engine at work can be obtained.The research is to optimizing engine
Can, it lowers consumption for machine energy-saving, accurate foundation is provided.
Invention content
The technical problem to be solved in the present invention is to provide a kind of preparing methods of engine load spectrum, can be quick and convenient straight
The loading spectrum of the display engine of sight, foundation is provided for optimization engine performance and oil consumption.
The present invention is to realize that the technical solution of its purpose is such：A kind of preparation method of engine load spectrum is provided,
It is characterized by comprising include the following steps:
Engine speed and engine load rate are acquired simultaneously with constant duration, respectively with engine speed for horizontal seat
Mark on abscissa and ordinate divides the two of grid to divide to be formed etc. at equal intervals using engine load rate as ordinate and respectively
Dimension coordinate chart；
By each collected engine speed and engine load rate according to its numerical value two-dimensional coordinate chart correspondence
It is cumulative that number is carried out in grid；
The recorded number of the grid is calculated and be shown in each grid of two-dimensional coordinate chart to account for engine speed and start
Machine rate of load condensate acquires the times of collection percentage of total degree；
Multiple default values are set between 0 to 100% and are divided into multiple sections by 0 to 100%, by adopting in each grid
Collection percentage of time adds up and judges in multiple sections of each secondary accumulation result between 0 to 100% successively from big to small
Residing section, the grid that times of collection percentage accumulation result belongs to same section are shown as same background color, acquisition time
The grid that number percentage accumulation result belongs to different sections between minimum default value and maximum preset numerical value is shown as the different back ofs the body
Scape color.Times of collection percentage accumulation result belongs to the area less than the section of minimum default value or more than maximum preset numerical value
Between grid be shown as white background.
Further, in the preparation method of above-mentioned engine load spectrum, engine speed and engine load rate are acquired
Time interval is 5 seconds to 60 seconds.
Further, in the preparation method of above-mentioned engine load spectrum, the abscissa in the two-dimensional coordinate chart is with 100
Switch to interval to divide, it is that interval divides that ordinate, which is with 10%,.
Further, in the preparation method of above-mentioned engine load spectrum, the default value is respectively 50%, 80%,
90%.
Further, in the preparation method of above-mentioned engine load spectrum, times of collection percentage accumulation result belongs to minimum
The background colour of the grid of default value and maximum preset numerical intervals and the grid background colour of other each numerical intervals are different.
Compared with prior art, the present invention the loading spectrum worked out through the invention, it being capable of quick and convenient intuitive display hair
The loading spectrum of motivation provides foundation for optimization engine performance and oil consumption.
Description of the drawings
Fig. 1 be two-dimensional coordinate chart grid in record the number figure of acquisition.
Fig. 2 is the engine load spectrum that times of collection percentage is shown in the grid of two-dimensional coordinate chart.
Fig. 3 is the engine load spectrum that the present invention finally works out.
Specific implementation mode
Illustrate specific embodiment below in conjunction with the accompanying drawings.
The ECU of existing EFI engine obtains parameter when engine work by the sensor on engine, to ginseng
Fix time after number processing the outside engine on performance parameter in interval, wherein engine speed when including just engine work and
Engine load rate.The preparation method of engine load spectrum in the present invention is exactly to acquire engine simultaneously with constant duration to turn
Speed and engine load rate usually acquire an engine speed and engine load with the time interval between 5 seconds to 60 seconds
Rate.Work out two-dimensional coordinate chart, wherein using engine speed as abscissa, using engine load rate as ordinate and respectively in cross
The two-dimensional coordinate chart for dividing grid such as to form on coordinate and ordinate to divide at equal intervals；Abscissa in two-dimensional coordinate chart
Switch to interval with 100 to divide, it is that interval divides that ordinate, which is with 10%, to form two-dimensional coordinate chart net in two-dimensional diagram
Lattice.Each collected engine speed and engine load rate are found into corresponding net according to its numerical value in two-dimensional coordinate chart
Lattice are simultaneously cumulative in grid progress number, as shown in Figure 1.
The recorded number of the grid is calculated and be shown in each grid of two-dimensional coordinate chart to account for engine speed and start
Machine rate of load condensate acquires the times of collection percentage of total degree, as shown in Figure 2.
Multiple default values are set between 0 to 100% is divided into multiple sections, such as default value point by 0 to 100%
It Wei 50%, 80%, 90%.Times of collection percentage in each grid is added up successively from big to small and judges each cumulative knot
Residing section in multiple sections of the fruit between 0 to 100%, times of collection percentage accumulation result belong to same section
Grid is shown as same color, and the grid that times of collection percentage accumulation result belongs to different sections is shown as different colours.
Also times of collection percentage that will be in each grid adds up successively according to sequence from big to small, when accumulation result is less than 50%
When, all colors for having carried out the cumulative grid of times of collection percentage are shown as the first background colour；By times of collection hundred
