(54) | Injector of fuel regulated electronycally |
(57) An injector for the injection of fuel in diesel motors by means of the system "common-rail"
that avoids the possibility of leak of fuel because of the waste, long term, of the
seat of the needle of the injector. The rotary valve of the injector is actuated by a solenoid (1) which is controlled by an Electronic Unit of Control (UEC) (2). The quantity of fuel that is injected, is regulated by means of the time that the ports (4',4") of the cylinder distributor (3) are open. Since to open the ports it is only necessary that they coincide, it is avoided this way the necessity of a spring that pushes a needle on a hole to close it, that which causes with the time a defect in the seat and therefore a possible leak of fuel. |
