Abstract
Because of the big influence on driveability and exhaust emissions one of the most important challenges of modern fuel injection systems is to ensure a very good constancy of the air/fuel ratio. A precise feedforward control especially for dynamic transitions is necessary because a feedback control of the air/fuel ratio based on an oxygen sensor in the exhaust gas is not able to avoid dynamic deviations. Therefore in this paper a new fuel injection technique is presented which is founded on a simultaneous control of air and fuel in connection with algorithms based on mathematical models of the different physical effects.
