Abstract
The utility model discloses a diesel preheating device, which comprises a discharge pipe of an automobile and an oil pipe which is connected with an oil injecting nozzle, wherein the other end of the oil pipe is connected with a high pressure oil pump, the middle portion of the oil pipe is located in the discharge pipe of the automobile, and an insulating layer is coated on the walls of the oil pipe between the discharge pipe of the automobile and the oil injection nozzle. The device can effectively preheat diesel, guarantees the full combustion of diesel, and reduces air pollution.
Description
Technical field
The utility model relates to a kind of diesel oil preheating device, in order to diesel oil is carried out preheating, guarantees that diesel oil fully burns, and reduces and pollutes.
Background technique
At the northern China cold area, because diesel fuel temperature is low in the fuel tank, usually cause diesel engine normally not start, and low temperature diesel oil is insufficient owing to burning, and can produce a large amount of black smokes, contaminated air influences productive life.
The model utility content
The purpose of this utility model is to provide a kind of diesel oil preheating device, and is not only simple in structure, is easy to make, and can carries out preheating to diesel oil, guarantees that diesel oil fully burns, and reduces atmospheric pollution.
The purpose of this utility model is achieved in that a kind of diesel oil preheating device, comprise motor vehicle exhaust and the transport pipe that links to each other with oil nozzle, the other end of transport pipe is connecting high pressure oil pump, the middle part of transport pipe is positioned at motor vehicle exhaust, coats on the transport pipe tube wall between motor vehicle exhaust and the oil nozzle thermal insulation layer is being set.
When the utility model uses, by the high-temperature tail gas in the motor vehicle exhaust low temperature diesel oil in the transport pipe is carried out preheating, the diesel oil after the preheating enters diesel combustion by oil nozzle again.The utility model is simple in structure, is easy to make, and can carry out preheating to diesel oil, guarantees that diesel oil fully burns, and increases work efficiency, and reduces atmospheric pollution.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment 1 a linkage structure schematic representation;
Fig. 2 is the utility model embodiment 2 a linkage structure schematic representation.
Embodiment
A kind of diesel oil preheating device as shown in Figure 1 and Figure 2, comprises motor vehicle exhaust 4 and the transport pipe 5 that links to each other with oil nozzle 6, and the other end of transport pipe 5 is connecting high pressure oil pump 3, and high pressure oil pump 3 is connecting fuel tank 1 by filter 2.The middle part of transport pipe 5 is positioned at motor vehicle exhaust 4, coats on transport pipe 5 tube walls between motor vehicle exhaust 4 and the oil nozzle 6 thermal insulation layer or electric heating thermal insulation cover are being set.During use, the low temperature diesel oil in the transport pipe 5 is carried out preheating by the high-temperature flue gas in the motor vehicle exhaust 4.The transport pipe 5 that is positioned at motor vehicle exhaust 4 is straight tube shape or elbow-shaped or broken line shape, in order to prolong the length of transport pipe 5 in motor vehicle exhaust 4, can also on transport pipe 5 tube walls that are positioned at motor vehicle exhaust 4, endothermic plate be set uniform interval, with further raising endothermic effect.
Claims (3)
