A New Simplified Carburetor for Small Engines 950272

The benefits of a well optimized carburetion, over the entire engine utilization range, are well known especially in conjunction with a catalytic aftertreatment of engine exhaust gas.Today, electronic injection systems appear very effective for the solution of the above mentioned problem, but their complexity, i.e. the number of components and the necessity of high current rates, and costs preclude their practical application on small engines.The proposed system, that maintains the simplicity of the standard carburetor and requires only small driving currents, for the simplified electronics, could represent a sound solution.In a first part, after a description of the system, flow bench tests are reported.In a second part the results of the practical applications on two different types of small motorcycle are presented.A detailed analysis of the parameters influencing the repeatability is also carried out.
