Carburetion control system

摘要

System for controlling the carburetion of an internal combustion engine comprising the following activities: a) starting the engine; b) determining the factor λo using any known method; c) measuring the ionization current cio; d) modifying—from outside—the factor λ by a predefined amount equivalent to Δλ bringing it to the value λ1=λo+Δλ; e) repeating the measurement of the ionization current ci1; f) calculating the value of the difference of the ionization current Aλci1 equivalent to cio−Ci1; g) repeating operations d. and e. until the difference between the last value of the ionization current o,η and the second last value cin-1 is smaller than Δci; where Δci is a predefined value which is assumed to have no influence with respect to the carburetion.

1. A system for controlling the carburetion of an internal combustion engine comprising the following activities:
a. starting the engine; b. defining a value λ0 of a lambda factor λ; c. measuring a value ci0 of an ionization current; d. modifying the lambda factor λ by a predefined amount equivalent to Δλ thereby changing the lambda factor to the value λ1=λ0+Δλ; e. repeating the measurement of the ionization current to get a second value ci1 thereof; f. calculating a value of a difference Δλci1 of the ionization current equivalent to ci0−ci1; g. repeating operations d. and e., thereby measuring the ionization current with different values λ1 . . . n, until a difference between a last value of the ionization current cin and a second to last value of the ionization current cin-1 is smaller than Δci, where Δci is a predefined value which is assumed to have no influence with respect to the carburetion; and h. restoring a second to last value λn-1 as the corrected value.
