Fuel oil heating system and engine system

Abstract

The invention relates to a fuel oil heating system and an engine system, relates to the field of starting engines, and mainly aims at fast starting an engine of the engine system at low temperature through the fuel oil heating system. According to the main technical scheme, the fuel oil heating system comprises heating devices, fuel oil nozzles and air inlet pipes; each heating device comprises a shell and a heating element arranged on the shell, the shells are provided with fluid inlets and fluid outlets, and overflowing holes communicated with the fluid inlets and the fluid outlets are formed in the shells; at least one part of each heating element is arranged in the corresponding overflowing hole, and the heating elements are used for heating fluid flowing through the overflowing holes; the fuel oil outlet ends of the fuel oil nozzles are connected with the fluid inlet ends of the heating devices; and the air outlet ends of the air inlet pipes are connected with the fluid inlet ends of the heating devices so that air outlets of the air inlet pipes can be communicated with fluid inlets of the heating devices. The engine system is suitable for a power device with an engine, such as various vehicles, generator units and steamers.

Description

technical field [0001] The invention relates to the technical field of starting an engine, in particular to a fuel heating system and an engine system using the fuel heating system. Background technique [0002] At present, engines generally use gasoline or diesel as fuel. Gasoline or diesel oil is generally produced through petroleum refining. In order to make full use of national coal resources and make the industrial structure of fuel oil more reasonable, there are now some engines that use methanol as fuel on the market. Among them, methanol can be refined from coal. As a result, the utilization rate of coal can be greatly improved. [0003] Among them, methanol has high viscosity at low temperature, and methanol has lower volatility than gasoline, and a large amount of heat is required for gasification, which makes it difficult to start an engine using methanol as fuel at low temperature. [0004] In order to solve the above problems, the engines in the prior art are ...

AI Technical Summary

Problems solved by technology

[0005] In the process of realizing the above technical solution, the inventor found at least the following problems in the prior art: the structure of the above two sets of fuel supply systems is relatively complicated and the cost is high; and the driver of the motor vehicle must detect two different fuel tanks or corresponding The injection volume of the fuel tank, the two fuel tanks cannot be mixed up when adding fuel, the operation is more cumbersome
