Device for feeding measured quantities of volatile fuel components particularly to the intake conduit of an internal combustion machine of a vehicle |
摘要 |
<p>Volatile fuel dosed injector for a motor vehicle combustion engine has electromagnetic valve (1) controlled by pulse width modulation and control through flow sensor (6) : A device for the dosed injection of volatile fuel constituents into the inlet tube of a motor vehicle combustion engine comprises an electromagnetic regeneration valve (1) controlled by a pulse width modulation proportional drive and a regulating circuit which is adjustable for external disturbances in the coil (2) current. Devices (6) determine the mass or volume flow through the valve and/or the gap between the valve seal (4) and seat and/or the hydrocarbon component of the volume flow and the coil current is adjusted depending on at least one of these.</p> |
