Self-adapting method of controlling the mixture ratio of an internal combustion engine injection system |
摘要 |
A self-adapting method of controlling the mixture ratio of an injection system, of an internal combustion engine. In each operating state of the engine and for each injector, the method determines a nominal quantity of fuel to be injected as a function of a number of engine parameters and operating conditions, an operating parameter as a function of a signal representing exhaust gas composition and of a proportional-integral regulating function and hot and cold correction coefficients indicating a correction to be made to the nominal quantity of fuel to take into account the effect on injection of different engines and different injection systems during hot and cold engine operation.
