Abstract:
The thesis is aimed at designing a fuel atomizer device to be incorporated in a fuel economizer system for use in petrol engines for more efficient fuel consumption. The principle adopted is based on the spraying paint machine. A compressor is used to compress air from the atmosphere and deliver it to the carburetor. The power required to operate the compressor is obtained by connecting the compressor pulley and the crankshaft pulley with a fan belt. A fuel atomizer device is used to ensure that correct orifice released air to the carburetor with the aid of control valve and air pressure gauge to ensure that correct air/fuel ratio is maintained. An air dryer is installed to absorb moisture from the air. An air cylinder is installed to store compressed air, while a high pressurized air incorporated inside the carburetor through a pipe and atomizer device’s orifice to atomize fuel into tiny possible particles to achieve a complete combustion and fuel economy. This was ascertained by testing vehicle with fuel economizer with measured quantity of fuel, noting the speedometer at the start of the vehicle for a certain distance and doing the same without a fuel economizer. The speedometer and time taken were recorded and graph of the result was shown in figure 4.20. The result showed that vehicle installed with fuel economizer device gives complete combustion than vehicle without it. It also reduces petrol waste, lessens pollution and installation is environmental friendly.
