Description
Technical field
The present invention relates to a kind of engine fuel supply system, especially relate to a kind of low temperature auxiliary starting system for alcohol fuel vehicle.
Background technique
At present, ethanol petrol progressively forms scale in the popularization of countries and regions such as China, the U.S. and Brazil, and especially Brazil's popularization is more extensive and ripe, and the ratio of ethanol also higher (being up to E100).The situation of petroleum-based energy anxiety can be effectively alleviated in the popularization of ethanol petrol, can the better protect environment.But because alcohol fuel self, cold start-up is relatively poor, and especially high proportion ethanol gasoline is under lower temperature, and therefore more difficult startup needs to solve the cold start-up problem.
Summary of the invention
The purpose of this invention is to provide a kind of low temperature auxiliary starting system for alcohol fuel vehicle, solve high proportion ethanol gasoline car cold start-up problem at a lower temperature, satisfy the requirement of car load normal driving.
The technical solution adopted for the present invention to solve the technical problems is: a kind of low temperature auxiliary starting system for alcohol fuel vehicle comprises car load fuel oil supply system, engine electric-controlled unit (ECU); Described car load fuel oil supply system comprises that main fuel tank, main oil pump and pipeline connect the oil sprayer in the engine air inlet tube; Described ECU is electrically connected and the control main oil pump; It is characterized in that: cold start gasoline tank is set is connected the cold start-up jet-sub that is arranged on the engine air inlet tube front end with cold start-up oil pump and pipeline; Also cooling-water temperature sensor is set and is electrically connected ECU at motor water channel place; Described ECU also is electrically connected and controls the cold start-up oil pump.
For further safety control cold start-up oil pump, between described cold start-up oil pump and cold start-up jet-sub connecting pipeline, solenoid valve is set also, described solenoid valve is electrically connected ECU.
Working principle of the present invention is, when car load ECU judged whether to need to adopt the gasoline auxiliary starting system by cooling-water temperature sensor, this system's fuel pump, solenoid valve began work, and car load main fuel supply system quits work simultaneously, guarantee that car load successfully starts smoothly, improves the cornering ability of car load.
Good effect of the present invention: owing to only adopt additional gasoline injection to improve cold starting performance, it is remarkable that the present invention uses advantage, is summarized as follows:
● car load is changed less, simple in structure, easy realization.
● this scheme reliable performance, with low cost.
● can effectively solve car load low-temperature startup and emission performance.
Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is a kind of low temperature auxiliary starting system for alcohol fuel vehicle organigram.
Among the figure: 1. motor, 2. cooling-water temperature sensor, 3. cold start-up fuel tank, 4. cold start-up oil pump, 5. solenoid valve, 6. cold start-up jet-sub, 7.ECU, 8. fuel tank, 9. engine air inlet tube, 10. oil pump, 11. oil sprayers.
Embodiment
Embodiment 1, and as shown in Figure 1, a kind of low temperature auxiliary starting system for alcohol fuel vehicle comprises car load fuel oil supply system, engine electric-controlled unit (ECU) 7.Described car load fuel oil supply system comprises that main fuel tank 8, main oil pump 10 and pipeline connect the oil sprayer 11 in the engine air inlet tube.Described ECU7 is electrically connected and control main oil pump 10.Cold start gasoline tank 3 is set is connected the cold start-up jet-sub 6 that is arranged on motor 1 suction tude 9 front ends with cold start-up oil pump 4 and pipeline; Also cooling-water temperature sensor 2 is set and is electrically connected ECU7 at motor water channel place.Described ECU7 also is electrically connected and controls cold start-up oil pump 4.
Core of the present invention is that car load ECU judges whether that according to water temperature needs adopt the gasoline auxiliary starting system, when system judges that the ethanol car need adopt cold starting system to start, by controlling main, the work of cold start-up oil pump, the opening and closing time of control cold start-up solenoid valve is controlled the emitted dose of gasoline, guarantees smooth ato unit.Wait to meet under the certain condition, close AFS Auxiliary Fuel Supply System, open the work of ethanol main oil pump, guarantee engine mildness, normal.
When the present invention specifically implements, before the ethanol car begins to start, car load ECU7 judges the ambient temperature of this moment by cooling-water temperature sensor 2, when temperature during less than 10 ℃, ECU7 starts 4 work of gasoline cold start-up oil pump, and while opens solenoid valve 5 is so that gasoline is ejected in the suction tude 9 by gasoline injection joint 6 from fuel tank 3, form the cylinder combustion burning that mixed gas enters motor 1, ato unit 1 with air then.When engine operation a period of time, after ECU7 satisfied hot machine by cooling-water temperature sensor 2 judgements, ECU7 opened oil pump 10 work of main fuel tank, closes oil pump 4 simultaneously, and this moment, car load switched to alcohol fuel work stably.
Arranging on the ethanol car, petrol tank 4 is installed can be plastics or metalwork, and this fuel tank also can have parts such as oil outlet, fuel liquid level, support and integrated carbon filling; This fuel tank can be arranged near the engine air inlet tube.
