Testing of a Mixture Preparation System for Spark Ignition Internal Combustion Engines

An experimental investigation of the performance of a mixture preparation system used with spark ignition internal combustion engines is presented. The proposed carburetor works on the principle of adiabatic vaporization of liquid gasoline fuel before it is led to engine cylinders by means of passing atmospheric air, induced by engine suction, through fuel. The study aims at the determination of parameters that affect the performance of this system.

It is demonstrated through the results that this carburetor is a better device for mixture preparation in spark ignition engines having numerous advantages over conventional carburetors most notably fuel economy.
