This paper presents a nonlinear modeling of a small combustion engine and its validation. The salient characteristic of the procedure is the fewness on the amount of sensors, in fact using only three commercial sensors available for other combustion motors, an error less than five percent was obtained during the identification process. As another important point, the control of the combustion engine replacing the original carburetor for a commercial injector using the same hardware utilized for identification (this time reprogrammed) made possible the control of the motor in closed loop forming in this way a cheap ECU.
