As shown in Figure 1, one embodiment of the invention proposes a kind of dual fuel engine fuel injection control method, specifically include
Following steps:
Step 100, the water temperature of the dual fuel engine is obtained, and determines oil spout map corresponding with the water temperature.
Wherein, the dual fuel engine includes multiple operation areas corresponding with multiple temperature ranges, and each fortune
Row region uses different oil spout map.
In this step, the water temperature of dual fuel engine can be obtained by the temperature sensor etc. being placed in engine cylinder.Spray
Oily map can be obtained by test, and which illustrate the corresponding relationships of engine speed, engine torque and distributive value, that is to say, that
By inquiring oil spout map, oil mass and Injection strategy can be determined according to the engine speed and engine torque of vehicle.Oil spout
The related data of map is to be obtained by the routine test of this field, therefore the present embodiment is not herein to the specific acquisition of oil spout map
Process is described.
According to the operating condition of dual fuel engine, the present embodiment preferably divides three fortune according to different engine water temperatures
Row region, comprising: cold operation region, medium temperature operation area and hot operation region.Wherein, low, medium and high temperature indicates
Three temperature ranges, and the corresponding temperature of these three temperature ranges is low temperature < medium temperature < high temperature.
Preferably, the corresponding temperature range in the cold operation region is less than 10 DEG C, and the medium temperature operation area is corresponding
Temperature range be 10 DEG C to 60 DEG C, the corresponding temperature traffic coverage in the hot operation region is greater than 60 DEG C.
In other embodiments of the invention, operation area, the fortune of division can also be divided using other temperature ranges

Multiple jeting areas, specific division methods are as follows.
One, cold operation region
As shown in Fig. 2, the present embodiment draws the oil spout map in cold operation region according to engine speed and engine torque
It is divided into two jeting areas, is the first jeting area 1 and the second jeting area 2.
First jeting area 1 uses pure diesel injection mode, including diesel oil sprays in advance, sprays after diesel oil main jet and diesel oil.Wherein,
It is sprayed with after diesel oil and is conducive to the row's of raising temperature, make DOC Fast light-off.In this jeting area, since engine water temperature is lower, gasoline is sprayed into
After cannot burn, therefore only carry out diesel injection.
Second jeting area 2 uses dual fuel injection mode, including gasoline gas-duct jetting, diesel oil spray in advance and diesel oil main jet.
In conjunction with Fig. 2 it is found that engine speed has reached a high value in this jeting area, therefore speed load is higher, belongs in vehicle
The region suddenly accelerated at low temperature, in this jeting area, hot atmosphere is higher in engine cylinder, and gasoline can burn when intervening,

It is bright, for some type of vehicle, this jeting area want demanded engine torque in 20Nm hereinafter, engine speed 900rpm with
Under, hot atmosphere is low in engine cylinder at this time, and gasoline is not easy compression ignition, to ensure that the pure diesel injection mode of the jeting area.
6th jeting area 6 uses dual fuel injection mode, including diesel oil sprays in advance and gasoline gas-duct jetting.This jeting area
For the optimal region of dual fuel injection, diesel oil only serves the effect of igniting, gasoline homogeneous combustion, and PM discharges almost nil, NOXControl
System is in a very low degree.But as shown in figure 4, the maximum engine torque of this jeting area is restricted.
7th jeting area 7 uses dual fuel injection mode, including diesel oil sprays in advance, diesel oil main jet and gasoline gas-duct jetting.
For the restricted problem of maximum engine torque of the 6th jeting area 6, this jeting area is the base in the 6th jeting area 6
Increase diesel oil main jet on plinth, expanded maximum engine torque, and keeps lower discharge and lower oil consumption.
Step 300, oil spout is carried out according to the corresponding oil spout map of the jeting area.

Injection.Comparison diagram 2 and Fig. 3, it is known that be changed into the predetermined value of the engine speed of the 4th jeting area 4 from third jeting area 3
Less than the predetermined value for the engine speed for being changed into the second jeting area 2 from the first jeting area 1, that is, show medium temperature Operational Zone
In domain, dual fuel injection can be used when engine speed is lower, advantageously reduces PM and NOXDischarge.
As shown in figure 4, when vehicle just starts starting, increasing with engine speed for hot operation region, by the 5th spray
The oil spout map for penetrating region 5 carries out pure diesel injection, after engine speed reaches a predetermined value, further according to engine torque
Value selects the oil spout map of the 5th jeting area 5 to continue pure diesel injection or the oil spout map progress pair of the 6th jeting area 6
Fuel injection, and when engine speed continues to increase to another predetermined value, and need according to the value of engine torque selection the
The oil spout map of five jeting areas 5 continues pure diesel injection or the oil spout map of the 6th jeting area 6 continues double fuel
The oil spout map of injection or the 7th jeting area 7 carries out dual fuel injection.It is apparent that the 6th jeting area be dual fuel injection most
Excellent region, but limited by maximum engine torque, and corresponding engine torque is greater than the 5th spray in the 7th jeting area
Region and the 6th jeting area are penetrated, the range of engine torque is extended.Corresponding diagram 2 and Fig. 3, it is known that in hot operation region
In, corresponding engine speed is run compared to cold operation region and medium temperature when being changed into dual fuel injection from pure diesel injection
Region wants small, i.e., in hot operation region, after starting vehicle, and reason needed for engine water temperature will soon rise to vehicle operation
Think temperature (such as 80 DEG C), guarantees that vehicle is smoothly run to not only improve, ensure that low oil consumption also by dual fuel injection mode
And low emission.
