Combined integrated fuel tank

Abstract

The invention provides a combined integrated fuel tank. The combined integrated fuel tank includes a fuel tank body; the fuel tank body is divided into four chambers through three non-porous partition plates, and the four chambers are a first chamber, a second chamber, a third chamber and a fourth chamber. The first chamber is a urea chamber, the second chamber is a heating chamber, the third chamber is formed into a fuel tank, and the fourth chamber is formed into an auxiliary fuel tank. Inlets and outlets are formed in all the chambers, and a porous partition plate is arranged in the center of the third chamber fuel tank to divide the third chamber fuel tank into several communicated spaces. A fuel amount change-over valve is connected with the position between the third chamber and the fourth chamber through pipes. By means of the combined integrated fuel tank, different functions are achieved through a plurality of the chambers, an independent urea tank and mounting support are canceled, the whole car cost is reduced, and the chassis space is saved; by means of the auxiliary fuel tank, the chassis space is saved, and the fuel tank fuel loading amount is increased; the auxiliary fuel tank is added, so that the car fuel injection efficiency is reduced, and time is saved.

Description

technical field [0001] The invention relates to auto parts, in particular to a composite integrated fuel tank. Background technique [0002] Automobile fuel tank is an indispensable part for automobile to store fuel. When the vehicle is running, the impact force generated by the fuel in the fuel tank will cause instability in handling, and the fuel tank is easy to crack and leak oil; National IV commercial vehicles have added exhaust emission catalytic device urea tank, At the same time, the installation bracket is added, which takes up space on the chassis; commercial vehicle fuel tanks generally have no auxiliary fuel tanks, and when the fuel is about to be exhausted, there is nowhere to refuel, which increases anxiety for drivers and passengers; urea and fuel are prone to urea crystallization and fuel freezing in winter; urea Tank and fuel tank heating devices are independent. [0003] Various fuel tanks fulfilling different functions have been disclosed in the patent li...
