Abstract

The utility model relates to a device for heating diesel oil using the waste heat of an internal combustion engine. The utility model is characterized in that the device is composed of a circulating water sheath and an additional water tank. The circulating water sheath is provided with a water inlet pipe and a water return pipe. The waste heat carried by circulating cooling liquid is used for heating the diesel oil. The utility model solves the problem that low grade diesel oil can not be used at northern area in winter. The fuel cost can be reduced by thirty percent to forty percent. The utility model has the advantages of no engine loading increase, energy saving, safe operation and wide application range. The utility model is suitable for diesel engine vehicles to install and use, such as a car, a tractor and an engineering machine.

Description

Diesel engine increase of temp. device by waste heat

The utility model relates to a kind of utilized device of waste heat of internal combustion engine, the device that the used heat that particularly utilizes cooling liquid of IC engine to take out of heats diesel oil.

In the winter time, especially northern area often makes the automobile of making motor with diesel engine because of temperature is low, and tractor etc. can not use low grade diesel oil, so strengthen fuel cost.Though available electric heating tube heats diesel oil, need in the work to convert kinetic energy to electric energy, so just increased the load of motor, expend the energy.

The purpose of this utility model provides a kind of output power that does not influence motor, the device that utilizes waste heat of internal combustion engine that diesel oil is heated, and low grade diesel oil easy to use reduces cost.

The utility model is achieved in that the used heat that utilizes cooling liquid of IC engine to take out of, according to different type of machines, distribute the circulating liquid of different amounts, by the utility model oil outlet tube in the fuel tank and oil plant on every side thereof are heated, the utility model is formed with the additional water tank that is installed in the fuel tank outside by being installed in the inner cyclic water jacket that forms the grease chamber of diesel oil tank, cyclic water jacket two ends welding annular roof plate, outer wall welding intake pipe and return pipe, on the annular roof plate of cyclic water jacket one end oil connection is housed, connects, screw with hollow screw with the fuel tank transport pipe, the other end and fuel tank base plate (seat) connect, according to the type difference, the welding baffle plate

Below in conjunction with most preferred embodiment and accompanying drawing the utility model is described in detail:

Fig. 1 is that the utility model is applied to liberate～the assembling schematic representation of 141 diesel cars.

Fig. 2 is the assembling schematic representation that the utility model is applied to Xingtai 190～12 type microtractors.

Embodiment 1:

When doing cooling liquid with water (Fig. 1): when using the hot water preheating before diesel engine is starting, hot water enters in the cyclic water jacket (3) from return pipe (5), to grease chamber (4) interior diesel oil heating.After car started, circulating water entered in the cyclic water jacket (3) from intake pipe (1), loops back in the motor from return pipe (5).Meanwhile; cyclic water jacket (3) bottom has the annular roof plate (2) of return pipe (5) one ends to be welded on the fuel tank base plate (9); the other end forms filler opening (shown in the arrow); the interior diesel oil of fuel tank is flowed in the grease chamber (4); return pipe (5) is connected in series a threeway discharging valve after stretching out fuel tank, when shutting down with assurance water is put only.On the annular roof plate (2) on cyclic water jacket (3) top, oil connection (10) is housed, connects, screw with hollow screw (11) with the fuel tank transport pipe.Oil transport pipe outside fuel tank flows out.

When doing cooling liquid: need be in the outside additional water tank (7) of installing of fuel tank with antifreeze liquid.Add boiling water to water tank (7) from water inlet (6), the interior diesel oil in preheating grease chamber (4) reaches the purpose of piloting engine, and waste pipe (8) is equipped with discharging valve, after car starts water is put only.

Embodiment 2:

When with the hot water preheating (Fig. 2): hot water enters in the cyclic water jacket (3a) from return pipe (5a), to grease chamber (4a) interior diesel oil heating.After car started, circulating water entered in the cyclic water jacket (3a) from intake pipe (1a), and (5a) loops back in the motor from return pipe.Meanwhile, cyclic water jacket (3a) outer wall is to diesel oil heating in the fuel tank.But do not have the interior diesel fuel temperature height in grease chamber (4a), baffle plate (12) can stop hot diesel oil and the interior diesel oil convection current of fuel tank in the grease chamber (4a), to guarantee oil temperature in the grease chamber (4a).A filler opening (shown in the arrow) is stayed in baffle plate (12) below, the interior diesel oil of fuel tank is flowed in the grease chamber (4a), its working principle is with embodiment 1, be fuel tank size and position according to different diesel versions, if design cycle water jacket size and mounting point, when mounted, the annular roof plate (2a) of cyclic water jacket (a) end is welded on the fuel tank outlet valve base, cyclic water jacket (3a) inner wall sleeve is on the diesel oil strainer, leave certain interval with coarse filter element, to guarantee oily circulation and enough oil masses.

Be equipped with on the diesel engine of thermostat, intake pipe of the present utility model is being concatenated into the warm short circle sebific duct of joint with sebific duct, and and the sebific duct of water tank major cycle and connecting.According to required heat calculation flow, the decision caliber.

The utility model can adopt 1,25～1, the thick iron of 5mm (aluminium, copper) plate is made.

The utlity model has following advantage:

1, use in winter low-grade diesel, but cut the cost of fuel 30～40%;

2, utilize waste heat of internal combustion engine, do not increase engine load, energy savings;

3, have wide range of applications, the diesel engine of all liquid cooling all can be installed and used;

4, through evidence temperature during at-20 ℃, oil temperature when machine runs well: single cylinder microtractor such as Xingtai 190～12 types can remain on 24～60 ℃, and the automobile oil outlet temperature is 50 ± 2 ℃, and is safe and reliable.

Claims

1, a kind of waste heat that utilizes makes the diesel oil warming device, it is characterized in that: it is made up of cyclic water jacket (3) and additional water tank (7), cyclic water jacket (3) two ends welding annular roof plate (2), outer wall welding intake pipe (1) and return pipe (5) are equipped with oil connection (10) on the annular roof plate (2) of cyclic water jacket (3) one ends, connect with the fuel tank transport pipe, screw with hollow screw (11), the other end and fuel tank base plate (seat) connect, according to the type difference, and welding baffle plate (12).
