Embodiment Construction

[0036] The engine system is a device that provides power for the running of the car. Its function is to burn fuel in the cylinder to generate power, and drive the wheels through the transmission system of the chassis, so that the vehicle can run normally. figure 1 is a schematic structural block diagram of an engine system for a vehicle dual fuel supply device 100 according to an embodiment of the present invention. Wherein, the dual fuels are the first fuel and the second fuel respectively. Specifically, the first fuel may be gasoline, for example, and the second fuel may be methanol, for example. The engine system may generally include: a dual fuel supply device 100 for controlling the engine 2 to work in any fuel mode in the dual fuel, and a dual fuel supply device 100 for controlling the dual fuel supply device 100 to supply any fuel to the cylinder of the engine 2 Combustion controller 1 and the first fuel supply system and the second fuel supply system. The engine syst...

Abstract

The invention provides a dual-fuel supply device used for a vehicle, an engine system and the vehicle. An engine of the vehicle can work under a work mode of any one fuel of dual fuels. The dual-fuelsupply device comprises a shell, two oil supply structures and a piston structure, wherein the shell is provided with two oil inlet ports and one oil outlet port; the two oil inlet ports are located in the side walls close to the two ends of the shell; the two oil supply structures are located inside a cavity of the shell and extend out of the two ends of the shell, so that the fuel entering any one oil supply structure through the corresponding oil inlet port is supplied to a cylinder of the engine through the oil outlet port, and is combusted to generate power; and the piston structure is located inside the cavity of the shell and located between the two oil supply structures, so that the dual fuels are prevented from being mixed in the cavity of the shell or one fuel is prevented from entering the oil outlet port operating under a work mode of the other fuel. The problems that a dual-fuel supply spraying rail structure is complex, compactness is low, and consequently arrangement isdifficult in the prior art are solved.

Description

technical field [0001] The invention relates to the field of vehicle fuel supply systems, in particular to a dual fuel supply device for vehicles, an engine system and the vehicle. Background technique [0002] Methanol fuel, as a clean energy source, has good development prospects in the application of the engine field. However, methanol engines are difficult to start cold and cause many problems such as poor fuel atomization and oil emulsification. Therefore, it is necessary to solve the cold start and the resulting problems. A series of questions are of great significance. Gasoline has good evaporability and combustibility. As a traditional energy source, it is beneficial to low-temperature cold start of the engine. Therefore, gasoline fuel can be used in methanol engines to assist low-temperature cold start of the engine. [0003] At present, there are many solutions for low-temperature cold starting of methanol engines, including electric heating solutions and starting...
