| 摘要 |
A device for monitoring the fuel/air ratio, wherein a vapour accumulator (3) receives at the inlet (3a,3b) fuel vapour coming from a tank (7) and an air flow (Qa) and feeds from the outlet (34) towards an intake manifold (12) of an engine a mixture of air and vapour. An electronic processor (16) receives at the input at least information correlated to the flow rate of air Qa aspirated into the accumulator (3) so as to calculate, on the basis of the flow rate of air Qa, the percentage p of vapour fed to the manifold (12) in relation to the total of vapour and air aspirated into the accumulator. <IMAGE> |
