The cooling liquid, the cooling liquid container, the evaporator and the fan are not required to be additionally arranged, the structure is simpler, the maintenance is easy, and the production cost is reduced; meanwhile, the temperature of the diesel oil is increased, so that the viscosity of the diesel oil is reduced, the volatility of the diesel oil is improved, the diesel oil is easier to atomize and combust in a cylinder, and the power of the diesel engine is improved.
Description
Technical field
The utility model relates to a kind of diesel engine of making cooling liquid with diesel oil.
Background technique
At present, the cooling means of the diesel engine of known pump circulation liquid cooling is: cooling liquid (water) absorbs the waste heat that the diesel oil detonation produces in the cylinder of diesel engine at the cooling duct of diesel engine, under the effect of water pump, via the pipeline inflow radiator, cooling back recirculation enters cooling duct in radiator.This cooling means has following shortcomings: it is a kind of waste of energy that radiator distributes heat; When outside air temperature is lower than the freezing point of cooling liquid (water), cooling liquid (water) will be frozen and can't be worked even machine part such as bursting by freezing radiator, therefore need add antifreezing solution when outside air temperature is lower than the freezing point of cooling liquid (water) in cooling liquid (water); Cooling liquid (water) deficiency or incrustation scale too much wait can influence the heat absorption of cooling liquid (water) to cylinder of diesel engine; Lax the skidding in fan belt can cause rotation speed of the fan to reduce, and air quantity reduces, and then influences the cooling of diesel engine.
Summary of the invention
The utility model purpose provides a kind ofly makes the diesel engine of cooling liquid with diesel oil, and it need not to be provided with in addition cooling liquid and container thereof, simple in structure, for ease of maintenaince, cost of production is low; Can make simultaneously diesel oil preheating improve temperature again, make that its viscosity reduces, volatility improves, easier in cylinder atomization combustion, improve diesel engine power.
The technical solution of the utility model is: a kind of diesel engine of making cooling liquid with diesel oil, comprise diesel fuel tanks, fuel oil supply system, the cylinder that is communicated with fuel oil supply system and be enclosed in the outer cooling duct of cylinder, described diesel fuel tanks is communicated with by transport pipe with the bottom of cooling duct, transport pipe is provided with oil transfer pump, the top of described cooling duct is communicated with a unify end of a thermostat of fuel supply system respectively, and the other end of described thermostat is communicated with diesel fuel tanks by return tube.
The further technological scheme of the utility model is: a kind of diesel engine of making cooling liquid with diesel oil, comprise diesel fuel tanks, fuel oil supply system, the cylinder that is communicated with fuel oil supply system and be enclosed in the outer cooling duct of cylinder, described diesel fuel tanks is communicated with by transport pipe with the bottom of cooling duct, transport pipe is provided with oil transfer pump, the top of described cooling duct is communicated with a unify end of a thermostat of fuel supply system respectively, and the other end of described thermostat is communicated with diesel fuel tanks by return tube; Scribble impervious barrier in the described cooling duct.
The utility model advantage is:
1. the utility model is so that the fuel of diesel engine--diesel oil is made cooling liquid; the waste heat that the diesel oil detonation produces in cylinder when absorbing the diesel engine acting with it; thereby Yin Wendu is not too high and impaired for the component of protection diesel engine; need not to be provided with in addition other cooling liquids and container thereof; also need not component such as radiator, fan; keep with the identical cooling effect of cooling unit in the past in, simplified the structure of diesel engine, the manufacturing that has reduced diesel engine and maintenance cost.
2. diesel oil has absorbed in cooling duct after the waste heat in the utility model, and the temperature of diesel oil can be controlled at about 90 degree with thermostat, and this is the optimum working temperature of diesel engine, and it is lower than the temperature of diesel oil nature; The more important thing is, after diesel fuel temperature promoted, its viscosity reduced, volatility improves, easier in cylinder atomization combustion, and then improved the power of diesel engine.
3. the utility model need not to add the antifreeze liquid of freezing liquid (water), and is easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein: 1 diesel fuel tanks; 2 transport pipe; 3 cooling ducts; 4 oil nozzles; 5 high-pressure oil pipes; 6 thermostats; 7 return tubes; 8 fuel oil supply systems; 9 oil transfer pumps.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: as shown in Figure 1, a kind of diesel engine of making cooling liquid with diesel oil, comprise diesel fuel tanks 1, fuel oil supply system 8, the cylinder that is communicated with fuel oil supply system 8 and be enclosed in the outer cooling duct 3 of cylinder, described diesel fuel tanks 1 is communicated with by transport pipe 2 with the bottom of cooling duct 3, transport pipe 2 is provided with oil transfer pump 9, the top of described cooling duct 3 is communicated with an end of a fuel oil supply system 2 and a thermostat 6 respectively, the other end of described thermostat 6 is communicated with diesel fuel tanks 1 by return tube 7, and return tube 7 is the easily material manufacturing of heat radiation.
Scribble impervious barrier in the described cooling duct 3, prevent the seepage and the volatilization of diesel oil.
During work, under the effect of oil transfer pump 9, diesel oil (among the figure shown in the dotted line) is entered the cooling duct 3 of diesel engine via transport pipe 2 by fuel tank 1, behind the waste heat that produces when absorbing diesel engine work, enter fuel oil supply systems 8 such as fuel filter, pump into oil nozzle 4 jet atomization burning in cylinder from fuel oil supply system 8 via high-pressure oil pipe 5 again.If the waste heat of diesel oil hyperabsorption in cooling duct 3, temperature are higher than the proper operation temperature of diesel engine, then the diesel oil return tube 7 that enters easy heat radiation from thermostat 6 returns in the fuel tank 1 again and makes natural cooling.
The utility model need not to be provided with in addition cooling liquid, cooling liquid container, vaporizer and fan, it is simple in structure, for ease of maintenaince, cost of production is low; Can make simultaneously diesel oil preheating improve temperature again, make that its viscosity reduces, volatility improves, easier in cylinder atomization combustion, improve diesel engine power.
