Abstract
The utility model discloses a fuel preheating auxiliary system of diesel vehicles, which comprises a diesel motor, a large oil tank, a waterway and an oil way which are connected with the diesel motor, wherein a waterway oil way separation-integration triplet and a conversion triplet are arranged on an oil way between the oil tank and the diesel motor, the conversion triplet is connected with a sub oil tank, the most part of the oil way is arranged in the waterway to be heated through the waterway oil way separation-integration triplet, thereby facilitating the diesel motor to combust low-grade diesel in cold winters, and reducing the operation cost. An oil pump is further arranged in the oil way for increasing the pressure of fuel and rapidly conducting paraffin deposit of the oil way to start the vehicle, when drivers have difficulties in starting the vehicle after forgetting to convert fuel. The fuel preheating auxiliary system has the characteristics of stable performance, free maintenance and convenient and fast installation.
Description
Technical field
The utility model relates to a kind of diesel car fuel-firing preheating auxiliary system.
Background technique
Present diesel car, in order to guarantee normal operation, can only keep locomotive with high grade diesel oil in the winter of cold and normally start operation, the locomotive that has has also increased independent liquid oil heater, this heater uses can solve the cold-starting problem, but need the burning high grade diesel oil, high grade diesel oil is with respect to low grade diesel oil, price height not only, and hundred kilometers fuel consumption are many, can not use under than the condition at the end in ambient temperature and low grade diesel oil is affected by environment, so just increase the operating cost of diesel car widely.
The model utility content
The utility model technical issues that need to address are to use low grade diesel oil that a kind of diesel car fuel-firing preheating auxiliary system is provided for cutting operating costs.
For addressing the above problem, technical solution adopted in the utility model is: a kind of diesel car fuel-firing preheating auxiliary system, this system comprises diesel engine, water tank, large tank, the water route that links to each other with diesel engine, the oil supply oil circuit, oil return circuit, this system also comprises drop tank, drop tank connects an end of crossover tee, the other end of crossover tee connects diesel engine by the oil supply oil circuit, the 3rd port of crossover tee connects the oil supply oil circuit, the oil supply oil circuit places the water route by deciliter threeway of water route oil circuit, wherein, a port of water route oil circuit deciliter threeway connects the oil supply oil circuit, the another port connects the water route, also have a port to connect the water route that is connected with the oil supply oil circuit, in like manner, oil return circuit also places the water route by deciliter threeway of water route oil circuit; Water route U type bending is stretched into large tank so that heated fuel oil.
This novel improvement is: also be provided with the oil pump that increases oil pressure in the oil supply oil circuit between large tank and the diesel engine.
Adopt the beneficial effect that technique scheme produced to be: cooling system that links to each other with diesel engine and fuel oil supply system, the part oil circuit of fuel oil supply system is set in the part pipeline of cooling system, so that utilize the fuel oil in the heat preheating supplying fuel pipeline of cooling liquid in the cooling system; By on the basis of former diesel car fuel oil system, increasing drop tank, and the fuel delivery diesel engine by crossover tee conversion drop tank and large tank, the major part of oil feed line is wherein passed from oil circuit, make diesel engine can fire low grade diesel oil in the winter of cold, reduced operating cost, oil pump also is installed in oil circuit, make the driver forget that the conversion fuel oil opens car at need, increase fuel pressure, rapidly the oil circuit of conducting wax deposition starts locomotive, and this is novel also to have stable performance, characteristics easily non-maintaining, quick for installation.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: 1, water route oil circuit deciliter threeway, 2, diesel engine, 3, the oil supply oil circuit, 4, the water route, 5, crossover tee, 6, drop tank, 7, large tank, 8, oil pump, 9, water tank, 10, oil return circuit, 11, the oil supply oil circuit.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
As shown in Figure 1, this novel diesel Motor Vehicle combustion in winter No. zero diesel systems mainly comprises diesel engine 2, water tank 9, large tank 7, drop tank 6 (between the volume 10-20 liter), diesel engine 2 is connected with crossover tee 5 by oil supply oil circuit 3, two other port of crossover tee 5 connects oil supply oil circuit 11 respectively, drop tank 6, the fuel oil that crossover tee 5 is used for changing supply is high grade fuel oil or No. zero fuel oil, when diesel engine 2 starts, drop tank 6 oil supply, because what store in the drop tank 6 is high grade diesel oil, so be easy to start diesel engine 2, after about 10-20 minute, engine temperature rising (temperature reaches more than 50 degrees centigrade), conversion by crossover tee 5, the supply reservoir of diesel engine 2 is switched to large tank 7, what store in the large tank is No. zero diesel oil, by large tank 7 fuel feeding, most of oil supply oil circuit 11 between large tank 7 and the diesel engine 2 and oil return circuit 10 pass through 4 pipeline centre by water by deciliter threeway of water route oil circuit, heat fuel oil by oil circuit, make oily temperature can remain on more than 20 degrees centigrade, thereby make diesel engine 2 in running, can use low-grade No. zero diesel oil; Be provided with oil pump 8 at the front end of oil feeding line 3 near the place of large tank 7, this oil pump can pressurize to the fuel oil that outputs to motor.
Using method: Qi Cheshi, the high grade diesel oil with drop tank 6 opens car earlier, starts after 10-20 minute, the oil temperature is when rising to more than 50 degrees centigrade, is transformed into by large tank 7 for low-grade No. zero diesel oil, put out car before, supply reservoir is switched to drop tank 6, move after 5 minutes flame-outly, be high grade diesel oil in oil circuit and the motor when guaranteeing that open car next time, if the driver has forgotten conversion when flame-out, during startup, open oil pump 8, increase oil pressure, can rapidly the oil circuit of wax deposition be got through, open car fast.
