Description
Technical field
The utility model relates to the legged lawn grass mower that a kind of compression-ignited internal combustion engine that adopts the single cylinder of flammable pluralities of fuel promotes.This internal combustion engine can use multiple fuel, diesel oil for example, clean diesel oil, esterification and do not have the plant wet goods of esterification.
Background technology
Now most legged lawn grass mower all is that internal combustion engine with spark ignition type promotes on the market, the utility model purpose is to promote legged lawn grass mower with compression-ignited internal combustion engine, for a long time, spark ignition type and compression-ignited internal combustion engine all are to do fuel with the fuel that the mineral oil of fluidization is drawn, the purposes of these two kinds of internal combustion engines also is similar, the main of these two kinds of internal combustion engines is respectively how to come pilot fuel, ignition internal combustion engine is outer next energy is lighted air and fuel in cylinder a mixture, this external energy is to chew (spark plug) through the spark in the moving system of establishing by cable of engine to light, compression ignition engine then is to rely on fuel reaching uniform temperature, spontaneous combustion during with the certain proportion of air and certain pressure.
Compression ignition engine is except the efficient of combustion fuel is higher, it also has the another one advantage: that is exactly that this internal combustion engine can use multiple fuel, these fuel comprise mineral diesel, and clean mineral diesel (ULSD) is a low-sulfur diesel-oil, artificial diesel oil, coal gas liquefaction diesel oil (GTL), kerosene, civil aviation fuel, military aviation fuel, esterified vegetable oil does not have the mixing of esterified vegetable oil and above any fuel.
The plant of having found in the whole world that contains vegetable oil has surpassed 1,000 kinds.With esterification and one of the advantage that do not have the vegetable oil of esterification to make the fuel of internal combustion engine is to reduce the carbonic acid gas in the exhaust and the content of carbon monoxide.In the world, only the pollution of U.S.'s horticultural machinery I. C. engine exhaust has just accounted for 5 percent of all I. C. engine exhausts pollutions.And with esterification and not have the vegetable oil of esterification to act as a fuel be the fuel of a kind of biological volume (biomass).Esterification and do not have the burning of the vegetable oil of esterification to have the characteristics of carbon balance (carbonneutral).The hours run of most legged lawn grass mower is very low.Just because the vegetable oil that this reason makes their internal combustion engine be more suitable for adopting esterification and there be not esterification is used as fuel.Here it is because some there is not the relevant problem (for example: carbon tires out problems such as collection and the tired collection of ester acid) of vegetable oil of esterification all to become not clear aquatic foods with burning.
Do not have the vegetable oil of esterification to comprise pure vegetable oil (PPO), pure rape oil (SVO), oil of having used that boils (UCO) and useless rape oil (WVO) etc., the vegetable oil of esterification is exactly the biodiesel that is processed by vegetable oil in general.
The utility model content
No matter most of compression-ignited internal combustion engines are that toroidal swirl type or indirect injection formula can be used most of above-mentioned fuel without repacking, and still, the vegetable oil that does not have esterification that effectively burn will be done some a spot of transformations to engine.
One of the purpose of this utility model is to overcome the defective that above-mentioned burning does not have the vegetable oil of esterification, and a kind of legged lawn grass mower that adopts compression-ignited internal combustion engine to promote is provided.It not only can use fossil fuel can also make plant fuel.
The technical solution of the utility model is: design a kind of legged lawn grass mower, this grass mower comprises the wheel that a chassis and a component are opened, a compression-ignited internal combustion engine is contained on this chassis, the output shaft that is contained in internal combustion engine that the cutting blade that is used to mow is direct or indirect, the pushing hands of grass mower is to be contained in the back on chassis, and fuel tank is contained on the chassis or on the engine.It has supplied with the fuel oil of engine, and this internal combustion engine can use multiple fuel, and the transformation of some engines can make its more effective burning there be not the vegetable oil of esterification, and the characteristics of these transformations are set out in claims.
For more effective burning there is not the vegetable oil of esterification, in the fuel tank of described internal combustion engine and engine for the electric heater that all is provided with on the cartridge to the vegetable oil heating.
For more effective burning there is not the vegetable oil of esterification, this compression-ignited internal combustion engine can adopt the fuel injection nozzle of single needle single hole, cooperates a kind of internal combustion engine top of pit type in direct injection.
For more effective burning there is not the vegetable oil of esterification, this compression ignition engine also can adopt the fuel injection nozzle of single needle porous or porous, cooperates a kind of internal combustion engine top of heat preserving type in indirect or direct injection.
For more effective burning there is not the vegetable oil of esterification, before the petrolift of this compression ignition engine and added high-quality fuel filter afterwards.
For more effective burning there is not the vegetable oil of esterification, the pressure of the petrolift of this compression ignition engine has increased.
As to improvement of the present utility model, on the air inlet pipe of described internal combustion engine, also can be provided with and be used for the pressurizer of increasing combustion engine admission pressure.This pressurizer will improve the efficiency of combustion of all various fuel, and described pressurizer is the turbine type pressurizer that promotes with engine exhaust gas.Or described pressurizer is the mechanical pressue device that drives with internal combustion engine output shaft.Or described pressurizer is to pressurize with the fan blower that battery drives.
The utility model since the internal combustion engine that has adopted flammable pure vegetable oil as lawn shear grass mechanomotive force source, and the burning of vegetable oil has the characteristics of carbon balance, so lawn shear grass facility have environmental protection, the advantage that little air is polluted.The inventor can make internal combustion engine enough simply and enough small-sizedly be more suitable for large-scale production.
