Abstract

The utility model relates to a plastic oil tank, in particular to an oil tank for an automobile, which is provided in order to solve the problem that the prior plastic oil tank lacks a fuel preheating device and can not be used in the low temperature environment. The oil tank comprises a tank body and an oil filler pipe orifice; and the oil filler pipe orifice is arranged at the top part of the tank body. The oil tank further comprises a fuel preheating device; and the fuel preheating device is arranged at the lower part of the tank body along the length direction of the tank body. The fuel preheating device solves the problem that winter in a northern area is so cold that automobile fuel is frozen and vehicles cannot be started; meanwhile, the fuel is preheated to improve the work efficiency of a diesel motor and reduce the energy loss; the body of the oil tank and an oil baffle plate are formed through integral injection-molding or blow-molding, thereby greatly reducing the processing cost and reducing the complexity of the processing technique; and a multilayer outer casing body sleeved outside the oil tank on the inner layer can play the role in providing thermal insulation, flame resistance, strong anti-bounce capacity, high temperature resistance and the like, so that the utility model can be widely applied to various fields.

Description

Plastic fuel tank

Technical field

The utility model relates to a kind of fuel tank, is specifically related to a kind of automotive oil tank.

Background technique

The northern area of China winter temperature is lower, outdoor temperature generally between-10 ℃～-20 ℃, some areas outdoor temperature even can reach-30 ℃～-40 ℃, this has brought very big difficulty for the ignition trigger that is placed on outdoor automobile.A denomination of invention is a kind of diesel engine plastic fuel tank that is provided with metal inserted piece, notice of authorization day is on May 17th, 2006, the patent No. is the Chinese utility model patent of ZL200520071348.6, though having solved the conventional diesel sump, it adopt welded steel plate to form, the cost height, Heavy Weight, the problem of long-time vibration oil impregnate easy to crack, but it is not with the fuel-firing preheating device, and plastic material can not be with the problem of naked light baking, seriously restricted its application region, and its processing technology complexity, cost is very high.

The model utility content

The utility model does not have the fuel-firing preheating device, the shortcoming that can not use, and a kind of plastic fuel tank that proposes in order to overcome existing plastic fuel tank in the environment of low temperature.

Plastic fuel tank, it comprises casing and filler neck; Filler neck is located at the top of casing; It also comprises the fuel-firing preheating device; The fuel-firing preheating device is installed in bottom in the casing along the casing length direction.

That the utility model not only has is simple in structure, processing technology simple, low cost and other advantages, and its fuel-firing preheating device solves northern area winter climate cold, vehicle fuel freezes the problem that can't start, simultaneously fuel oil is carried out preheating, can also improve the working efficiency of diesel engine, reduce energy loss; Fuel tank casing and the injection moulding of oil baffle integral type or blowing form, and greatly reduce the complexity of processing cost and reduction processing technology, and the upper and lower part casing adopts the infrared bonding connection technology, not only overcome difficulty on the technology, and weldquality are good, not easy to leak; Be sleeved on the outer multilayer package body of internal layer fuel tank, can play insulation, fire-retardant, impact resistant capability is strong, effect such as high temperature resistant, makes it be widely used in every field.
