Description
Technical field
The utility model relates to a kind of diesel fuel heating equipment, belongs to the starting aid technical field of combustion engine.
Background technique
At present single cylinder diesel engine is in the cold start-up situation, especially during cold-starting, when being in low temperature due to diesel oil, can have freezing phenomenon, and in cylinder, available amount of gasoline is less, therefore starts more difficult; For improving amount of gasoline in cylinder, facilitate it to start at low temperatures, general measure is multiway oil, yet so, is easy to occur flooding the cylinder phenomenon, motor can't normally start, and makes troubles to the user.
Have based on this, make the utility model.
The model utility content
The purpose of this utility model is to provide a kind of motor that makes and also facilitates the fuelizer that starts when cold conditions especially low-temperature condition.
For achieving the above object, the technological scheme taked of the utility model is as follows:
The diesel fuel heating equipment comprises plunger, oil intake nozzle, electric heating wire and oil nozzle, and plunger is between oil intake nozzle and oil nozzle; Electric heating wire is helical, and is parallel with plunger, is arranged at the oil nozzle place, and described electric heating wire is connected power supply.
For realizing better using effect, further arrange as follows:
Described plunger is connected with oil intake nozzle, and the joint is provided with seal ring.
Working principle of the present utility model and beneficial effect are as follows:
The utility model heating equipment is arranged in the single cylinder diesel intake duct, during starting electrical machinery work, power initiation, the electric heating wire heating power, simultaneously, fuel enters through oil intake nozzle, and under the effect of plunger, enter oil nozzle, due to high-pressure atomization, after the electric heating wire of fuel through heating, can produce spark, and together enter the firing chamber with air-flow, other fuel that ignition combustion is indoor, thereby realize the purpose of the easy ignition of fuel under cold state, need not to take other measure can realize the quick startup of motor.
The utility model is simple in structure, and is easy for installation, can be directly existing fuel tube intake duct on add and get final product, need not too much retrofit work, can solve the engine cold-start hard problem.
