Abstract
The utility model provides a preheating system for an ethanol gasoline engine. The preheating system for the ethanol gasoline engine comprises a storage battery, an electronic control unit, a preheating module and an electrical heating gasoline atomizer, wherein the storage battery, the preheating module and the electrical heating gasoline atomizer are connected in sequence through wiring harnesses, and the electronic control unit is connected with the preheating module through a wiring harness. According to the preheating system for the ethanol gasoline engine, the electrical preheating gasoline atomizer is used for heating ethanol gasoline, and thus the effects that the ethanol gasoline can be atomized sufficiently at low temperature, and the engine can be normally started at low temperature are ensured.
Description
Technical field
The utility model relates to the flexible fuel vehicle field, particularly ethanol petrol cold start-up field.
Background technique
The alcohol fuel oxygen content is high, is conducive to abundant burning, and can effectively reduce motor vehicle exhaust emission, improves energy resource structure, is a kind of novel reproducible clean fuel.But compare with gasoline, the alcohol fuel fire behaviour is poor, cold starting performance is poor, often in alcohol fuel, add in actual applications a small amount of gasoline to improve its cold starting performance, this fuel combination is called ethanol petrol, different according to the fusion rate of mixing gasoline, can be divided into again low-concentration ethanol gasoline and high concentration ethanol gasoline.Use the motor of ethanol petrol under low temperature condition, still be faced with fuel volatility poor, the problem of cold start-up difficulty, seriously the ethanol petrol of restriction promotes the use of.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of ethanol petrol preheating system for engine that can effectively improve engine cold-start.
For solving the problems of the technologies described above, the ethanol petrol preheating system for engine the utility model proposes comprises storage battery, electronic control unit, warm-up block and electric heating oil sprayer, wherein storage battery, warm-up block and electric heating oil sprayer are connected successively by wire harness, and electronic control unit is connected with warm-up block by wire harness.
Preferably, also be connected with safety fuse cutout between described storage battery and described warm-up block.
More preferably, the rated current of described safety fuse cutout is 70A.
Preferably, also comprise relay, described relay is connected with described electric heating oil sprayer with described electronic control unit respectively by wire harness.
More preferably, the rated current of described relay is 70A.
The utility model, by using the electric heating oil sprayer to be heated ethanol petrol, has guaranteed ethanol petrol also fully atomization when low temperature, and the motor machine also can normally start when low temperature.
The accompanying drawing explanation
The embodiment's that Fig. 1 is the utility model ethanol petrol preheating system for engine structural representation.
In figure, indicate as follows:
Storage battery-1, electronic control unit-2, warm-up block-3, electric heating oil sprayer-4, safety fuse cutout-5, relay-6.
Embodiment
For above-mentioned purpose, the feature and advantage that make model utility can become apparent more, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
A lot of details have been set forth in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here and implement, those skilled in the art can be in the situation that do similar popularization without prejudice to the utility model intension, so the utility model is not subject to the restriction of following public specific embodiment.
As shown in Figure 1, the ethanol petrol preheating system for engine that the utility model provides comprises storage battery 1, electronic control unit 2, warm-up block 3 and electric heating oil sprayer 4, wherein storage battery 1, warm-up block 3 and electric heating oil sprayer 4 are connected successively by wire harness, and electronic control unit 2 is connected with warm-up block 3 by wire harness.
In the utility model, when ambient temperature during lower than 20 ℃, electronic control unit 2 is when engine start, send duty cycle signals to warm-up block 3, after warm-up block 3 receives signal, increase by the average current of electric heating oil sprayer 4, the heating-up temperature of electric heating oil sprayer 4 raises, ethanol petrol in heating electric heating oil sprayer 4, ethanol petrol after heating is spurted in motor, ethanol petrol under high temperature obtains the volatilization of atomization preferably, thereby reaches the condition of lighting, and has guaranteed the engine start success.In whole start-up course, electronic control unit 2 continues to send duty cycle signals to warm-up block 3, thereby guarantee electric heating oil sprayer 4 continuous heatings, make the abundant atomization of alcohol fuel in the engine cold process, guaranteeing has the alcohol fuel of lasting abundant atomization to spurt in motor in start-up course, can be continuous light.Along with the temperature rising of motor, when meeting the atomization temperature condition of ethanol petrol, electronic control unit 2 stops sending duty cycle signals to warm-up block 3, and 4 heating of electric heating oil sprayer stop, and engine cold-start finishes.
Preferably, between storage battery 1 and warm-up block 3, also can connect safety fuse cutout 5 by wire harness, when preventing that system circuit is short-circuited, each component in infringement pre-heating system loop.More preferably, select the safety fuse cutout that rated current is 70A, to reduce costs, guarantee the pre-heating system normal operation in the protection loop.
Preferably, between electronic control unit 2 and electric heating oil sprayer 4, also can connect relay 6 by wire harness, when preventing that system circuit is short-circuited, each component in infringement pre-heating system loop.When ethanol petrol preheating system for engine loop is short-circuited, electric current sharply raises, electronic control unit 2 block system relays 6, and electric heating oil sprayer 4 stops heating, thereby prevents electric heating oil sprayer 4 excess Temperatures and damage.More preferably, select the relay that rated current is 70A, to reduce costs, guarantee the pre-heating system normal operation in the protection loop.
Although the utility model is described in conjunction with above embodiment, but the utility model is not defined to above-described embodiment, and only be subject to the restriction of claims, those of ordinary skills can easily modify to it and change, but do not leave essence design of the present utility model and scope.
