Abstract
The utility model relates to a car oil heating installation including a water tank, a water pump, a liquid heater and a warming tube composed by the radiators, characterized in that, a branch is arranged in parallel on the feedwater pipe of the radiators, a plurality of heat exchangers and the engine water circulating system are connected in series on the branch. A fuel preheating loop is arranged on the car tank, and a plurality of heat exchangers, the circulating oil pumps and the pressure oil pumps are connected in series on the fuel preheating loop, wherein one of the heat exchangers is immerged in the car tank. A pair of motored normal open solenoid valves and normal close solenoid valves, a normal close solenoid valve motored with the water pump is arranged on the water tube. The utility model has convenient and simple refit, reasonable design, strong service dependability, which can be used in the diesel motor car of the northern cold area.
Description
One, technical field
The utility model relates to the automobile oil supply system, is specifically related to a kind of vehicle fuel Preheating unit.
Two, background technique
At northern area, winter is very cold, and automobile adds low grade diesel oil and can freeze, and influences fuel delivery, and motor is with cisco unity malfunction.Generally come in the winter time temporarily, automobile has to use the diesel oil of high grade.High grade diesel oil exceeds much than low grade diesel oil price, uses high grade diesel oil very uneconomical.Therefore, in order to reduce cost, continue in the winter time to use low grade diesel oil, the someone adopts electrical heating method, and also the someone adopts the method for tail vapour heating.Electric heating power consumption is higher, can't heat and dissolves automobile high pressure oil pump fuel oil, and catch fire easily, and is dangerous high; Tail vapour mode of heating motor can't start, and can't work when perhaps inoperative.All there is the defective that is difficult to overcome in above-mentioned two kinds of methods.At present, on some automobile, particularly on the motorbus liquid heater is installed, when the winter driving of cold, for heating in the compartment.Because the liquid heater of heating usefulness has been installed on the car, the Preheating unit that utilizes liquid heater circulation loop heating vehicle fuel has been arranged now, but, the repacking of vehicle fuel Preheating unit at present exists installs complexity, it is many that pipeline is arranged joint, hidden danger such as the fuel pipe fault is frequent, and it is unreliable to work.
Three, summary of the invention
The purpose of this utility model is in order to overcome the deficiency of prior art, provides that a kind of repacking is easy, circuit design is reasonable, the vehicle fuel Preheating unit of reliable operation.
A kind of vehicle fuel Preheating unit of the utility model, comprise by water tank, water pump, the heating pipeline that liquid heater and radiator are formed, be characterized in: a normally closed solenoid valve one is set on the described radiator inlet pipeline, in parallel with described normally closed solenoid valve one branch road is set, heat exchangers in series one successively on the described branch road, heat exchanger two, heat exchanger three, the heat exchanger four and the engine water circulatory system, automotive oil tank is provided with the fuel-firing preheating loop, described fuel-firing preheating loop is to set out oil pipe and return tube in automotive oil tank, the described heat exchanger one of on the pipeline between described oil outlet tube and the described return tube, connecting successively, oil circulating pump, described heat exchanger three, high pressure oil pump and described heat exchanger two, described heat exchanger four is immersed in the automotive oil tank, a normally open solenoid valve is set on the outlet pipe of described heat exchanger three, be provided with between connection water pipe between the described heat exchanger four and the engine water circulatory system and the heating installation return pipe and be communicated with water pipe, on the described connection water pipe normally closed solenoid valve two is set, described normally closed solenoid valve one and the interlock of described normally open solenoid valve, described water pump and two interlocks of described normally closed solenoid valve.
The utility model working principle: during starting cold, liquid heater and pump working, solenoid valve all is failure to actuate, the hot water that comes out from liquid heater enters heat exchanger one successively, heat exchanger two, heat exchanger three, the heat exchanger four and the engine water circulatory system, enter radiator then, arrive the heating installation return pipe again, form water cycle, slightly after the heating, the oil circulating pump starting, fuel oil is extracted out from oil outlet tube, enters heat exchanger one successively, heat exchanger three, high pressure oil pump and heat exchanger two, return fuel tank through return tube again, the circulation of formation fuel oil, fuel oil and hot water carry out sufficient heat exchange like this, and fuel oil is heated, high pressure oil pump also is heated, and can satisfy to be engine oil.When stopping, engine misses are if the temperature in the maintenance compartment, liquid heater and water pump still work on, normally closed solenoid valve one and normally open solenoid valve interlock, and normally closed solenoid valve one is opened, normally open solenoid valve cuts out, and hot water only circulates in radiator, for heating in the compartment.When weather was not cold, liquid heater did not need work, water pump and normally closed solenoid valve two interlocks, and water pump stops, and normally closed solenoid valve two is opened, engine water circulatory system proper functioning.
The utility model has the advantages that: reequip easy, circuit design is reasonable, functional reliability is strong.
Four, description of drawings
