Description

Fuel gas phase conversion device for internal combustion engine

technical field

The utility model belongs to a fuel-saving auxiliary device for an internal combustion engine, in particular to a fuel-saving device for converting fuel oil into a gas phase before the fuel oil enters a cylinder, thereby improving fuel combustion efficiency.

Background technique

In order to save fuel for automobiles, improve combustion efficiency, and improve the environmental protection effect of automobile emissions, many technologies for fuel-saving and environmental protection of automobiles have been proposed. Although most of these technologies have different degrees of fuel-saving and environmental protection effects, they still need to be further improved to make fuel economy more efficient and emissions more environmentally friendly. Therefore, further improved techniques need to be proposed.

Utility model content

The purpose of the utility model is to solve the above-mentioned technical problems, and propose a gas-phase conversion device for fuel oil of an internal combustion engine, which greatly improves the fuel combustion efficiency and environmental protection effect of the internal combustion engine, and has a simple structure.

The purpose of this utility model is achieved through the following technical solutions: an internal combustion engine fuel gas phase conversion device, which is characterized in that: an extension pipe is connected to the exhaust valve of each cylinder of the internal combustion engine, and the other end of the extension pipe is connected to the exhaust gas of the automobile The fuel supply pipe of the car is spirally wound several times on the extension pipe.

The supplementary scheme that the utility model progresses and perfects and implements is:

The oil supply pipe of the automobile is also provided with a catalytic box, which is provided with catalyst particles and filter screens for cracking fuel molecules, and the catalytic box is connected to the oil supply pipe through the front and rear inlets and outlets.

The utility model uses the high-temperature exhaust gas discharged from the cylinder to preheat the fuel, or passes through a catalytic box for cracking fuel molecules to convert the fuel from a general liquid state to a gaseous state or a mixed state of liquid and gas, so that the combustion efficiency is greatly improved. The utility model has the advantages of simple and ingenious structure, easy manufacture and installation, can greatly save fuel and obviously improve the environmental protection effect.
