Separated space capacity changeable multi-fuel oil tank

Abstract

The invention belongs to the technical field of fuel tanks for supplying fuel oil for motor vehicles and in particular relates to a separated space capacity changeable multi-fuel oil tank. The separated space capacity changeable multi-fuel oil tank is mainly composed of a cover plate, a tank body, a baffle plate a, a push rod a, a push rod b, a baffle plate b, a high-elasticity airbag and a control system and the like; an inner space formed by the cover plate and the tank body is divided into a cavity a, a cavity b and a cavity c through the baffle plate a and the baffle plate b; the high-elasticity airbag is arranged in the cavity a and natural gas fuel is stored in the high-elasticity airbag; gasoline fuel is stored in the cavity b; diesel oil fuel is stored in the cavity c; the controlsystem can be used for driving the baffle plate a and the baffle plate b to slide along an inner wall of the tank body, so that the capacity of each cavity is changed and the capacity of a storage space of each type of fuel can be changed. The oil tank provided by the invention can be used for storing the single fuel and also can be used for storing various types of fuel at the same time; the space is greatly saved and the specific mass level of a whole vehicle is improved; an operation mode of an engine is convenient to match and the fuel is reasonably stored, and the space utilization rate is improved.

Description

technical field [0001] The invention belongs to the technical field of fuel supply fuel tanks for motor vehicles, and in particular relates to a multi-fuel fuel tank with variable partition volume. Background technique [0002] With the increasingly stringent regulations on fuel consumption and emissions of automobiles, many engine energy-saving and emission-reduction technologies have emerged as the times require. At present, the research on multi-fuel engine, integrated multi-fuel EFI system and control method has achieved preliminary results, but the research on the design of its fuel supply source is almost blank. At present, in the research process of multi-fuel engines, each required fuel is stored in different fuel tanks independently. Multiple fuel tanks take up a lot of space in the vehicle, which is not conducive to compact and lightweight design, and reduces the vehicle ratio. The quality level is contrary to the goal of energy saving and emission reduction. The...
