Description
Technical field
The present invention relates to alcohol engine technical field, particularly relate to the cold starting system of alcohol engine.
Background technique
As everyone knows, the methyl alcohol energy is the best substitute of energy source of car, but automobile burning methyl alcohol is under current technology prerequisite, also do not obtain very large popularization, because methyl alcohol burning-point is low, during low temperature, single fire methyl alcohol is not easy to catch fire, engine start difficulty, so a left side causes methanol vehicle to be promoted widely.Cold start-up is the development obstacles of methanol vehicle, and the cold start-up therefore solving methanol vehicle is the most important thing.
The cold start-up of current solution alcohol engine has following several mode:
One, in Aalcohols fuel, a certain proportion of gasoline and additive is added.But gasoline and adding of additive can cause impurity blocking oil pipe in crude oil case, make automobile burning insufficient, then are the qualities changing oil, cause a lot of chemical reactions.Additive cost is high in addition, and proportioning is complicated, and long term storage is easily divided into the insurmountable problems such as rotten.
Two, increase a set of gasoline cold-starting device, be placed in intake manifold.Gasoline is transported in motor in advance, but it can not oil spout for a long time, otherwise just cylinder plug, moreover its rotating speed that the engine long time can not be made to reach stable, like this motor, Starter, storage battery, cylinder etc. are caused damage, also from tempering intake manifold, the accident of vehicle fire can be caused, existing precedent.What from intake manifold, tempering caused vehicle to burn has a lot of report.
Three, electrically heated line is adopted to carry out fuel dispenser heating, the line of heating is adopted to start, this mode can not engine warming up, can only the fuel Heating in oily rail, but it does not have the effect of cold start-up completely, moreover heating time is long, time length very large to the electric quantity consumption in storage battery has been used up the electricity in storage battery a bit.Do not have electricity to carry out ato unit on the contrary, cause unnecessary trouble to user, to be just all out of use afterwards so much automobile-used.
Four, increase flange and be mounted to the two spray of double track, utilize gasoline to start.Increase flange and install oil nozzle, vehicle refitting being become this mode of double track double-spraying type, is current state-of-the-art cold-starting device, but there is a lot of challenge, in a lot of motor car engine, gap is very little can not increase flange, and vehicle is many, flange configuration is difficult, cost is high, uses the two spray joint of double track many, the risk of invisible increase fuel leakage, moreover he will change motor, on the engine a flange is installed, adds a set of oily rail, engine front cover with enter discrimination tracheae and will all take apart.User to change send out for motivation exist suspection attitude, this user beyond affordability it.This technology is caused not popularized in an all-round way.
Therefore, the cold start-up problem solving alcohols duel fuel engine is needed badly.
Summary of the invention
For above-mentioned defect and the problem of prior art, the object of this invention is to provide the cold starting system of alcohol engine, two are adopted to enter the oily rail that a hydraulic fluid port out connects design soon, the Aalcohols fuel in oily rail can be converted to gasoline rapidly, adopt single fire gasoline to carry out vehicle launch, thus thoroughly solve the world-famous puzzle of methanol and alcohol powered automobile cold start-up.Solve the cold start-up problem of alcohol engine.
In order to achieve the above object, the invention provides following technological scheme:
