This project in its present form is a device used for reducing pollution, fuel consumption and improves the mixing process in gasoline engines.
The environmental pollution problem is one of the greatest problems in the modern age, as well as the increasing of fuel consumption and its high cost. The effective solution is to use a homogeneous mixture of air and fuel in the carburetor gasoline engine.
In this project, several tests have been done on Mercedes and Volkswagen cars (as they have different characteristics and mechanical structure) , studying the quantity of consumption and temperature of exhaust gases.
A device has been manufactured in the school`s workshop with simple tools and material, so that it is very simple and cheap.
The device is a simple metal spring with special features (high humidity resistance, dynamic form to decrease friction..), installed in the suction pipe of the engine which makes the fuel particles (drops) smaller and smaller and creates a circumvolution in the suction pipe, so that a homogeneous mixture is obtained and admitted to the cylinders. Two different sizes have been manufactured to fit the Mercedes and the Volkswagen, as the size of the suction pipes of the two models is different.
After fixing the spring to the two models, it has been found that the fuel consumption was reduced by 10 -20 %, and the temperature of the exhaust gases was lowered by app. 20oC.
We find this technique is a method to reduce pollution on earth.
