Description

Fuel Control Device for Butanol Fuel Engine

Technical field:

The utility model relates to a fuel control device for a butanol fuel engine.

Background technique:

Gasoline and diesel combustion provide power for the engine, and there are environmental pollution problems due to insufficient combustion. Using butanol instead of gasoline to provide power for the engine has insufficient power. If it is directly mixed in the fuel tank, the calorific value of the fuel will be fixed and the flexibility will be poor. There are currently no fuel control devices for butanol fueled engines.

Invention content:

The purpose of the utility model is to provide a fuel control device for a butanol fuel engine.

Above-mentioned purpose realizes by following technical scheme:

A fuel control device for a butanol fuel engine, which comprises: a butanol fuel tank, a fuel pump is installed in the butanol fuel tank, the fuel pump is connected to a single-chip microcomputer through a wire, and is connected to a butanol fuel filter through an oil pipe. cleaner, the butanol fuel filter is connected to the butanol flow limiting valve through the oil pipe, the butanol flow limiting valve is connected to the input end of the fuel mixing chamber through the oil pipe, and the input end of the fuel mixing chamber is connected to the Gasoline flow limiting valve, the output end of the fuel mixing chamber is connected to the fuel injector, and the gasoline flow limiting valve is connected to the single-chip microcomputer; wherein, a pressure sensor is installed at the front end of the gasoline flow limiting valve, and the pressure The sensor is connected to the single chip microcomputer.

A fuel control device for a butanol fuel engine, the fuel mixing chamber includes a casing, the input end of the casing is inserted with two inlet pipes, the output end of the casing is inserted with an outlet pipe, and the casing is fixedly installed Two drive shafts, the drive shafts are connected to the motor and the stirring blade set.

The beneficial effects of the utility model:

The fuel control device of the butanol fuel engine designed by the utility model is an improvement carried out on the existing engine. The fuel injector is the original nozzle of the automobile. Reaching the fuel mixing chamber and providing power at the same time has the advantages of low modification cost, increased engine power, and reduced fuel pollution.

In the specific working process, the single-chip microcomputer is used to receive the throttle opening signal to calculate the fuel injection quantity, and then distribute the opening of the two restrictor valves, the butanol restrictor valve and the gasoline restrictor valve, to ensure that the required amount of fuel enters the fuel mixture. room. In addition, the pressure sensor is used to detect the pressure of the butanol fuel filter. When the pressure drops, the single chip microcomputer gets a signal, and then controls the fuel pump in the butanol fuel tank to work.

In the fuel mixing chamber, the blades of the stirring blade group rotate against the flow direction of the liquid to form turbulent flow, so as to achieve the purpose of fully mixing the fuel and reducing the probability of deflagration. This device for controlling the fuel mixing ratio before fuel combustion also has the advantage of being able to reasonably match the calorific value of the fuel so that the engine power can be adapted to different road conditions.
