Abstract

LA NUOVA INDUZIONE HA LUCE DI SCARICO CHE SI TROVA SULLE PARETI DEL CILINDRO IN ALTO, NELLA ZONA IN CUI LE FASCE NON ARRIVANO. LA VALVOLA DI CARICO HA FORMA INUSUALE "A CIAMBELLA" PER OTTENERE LA MASSIMA AREA DI PASSAGGIO. PER LO SCARICO E' NECESSARIO CHE LA VALVOLA ABBIA FORMA SIMILE ALLA FESSURA DI SCARICO, OVVERO CIRCONFERENZIALE, PARIMENTI AL CILINDRO, POICHE' L'APERTURA DA OCCLUDERE SI SVILUPPA TUTTO ATTORNO LA PARTE SUPERIORE DEL CILINDRO. IL COMANDO DI ALZATA DI ENTRAMBE LE VALVOLE E' DEMANDATO AD UNA DISTRUZIONE PARTICOLARE CHE CONSTA DI UNA SOLA MOLLA DI RICHIAMO PER AMBO LE VALVOLE E DI DUE CUSCINETTI REGGISPINTA, DOTATI DI DOSSI NELLA FACCIATA ADIACENTE ALLE PUNTERIE A RULLO, CHE IMPONGONO LA LEGGE DI ALZATA. ARCHITETTURA SIFFATTA LASCIA AMPIA LIBERTA' PER IL DISEGNO DELLA CAMERA DI COMBUSTIONE.THE NEW INDUCTION HAS EXHAUST LIGHT WHICH IS ON THE CYLINDER WALLS ABOVE, IN THE AREA WHERE THE BANDS DO NOT ARRIVE. THE INLET VALVE IS UNUSUAL "DONUT" TO GET THE MAXIMUM PASSAGE AREA. FOR THE DISCHARGE IT IS NECESSARY FOR THE VALVE TO HAVE A FORM SIMILAR TO THE DISCHARGE SLOT, OR CIRCUMFERENTIAL, ALSO TO THE CYLINDER, BECAUSE THE OPENING TO BE OCCLUDED IS DEVELOPED ALL AROUND THE TOP OF THE CYLINDER. THE LIFTING COMMAND OF BOTH VALVES IS COMMANDED TO A PARTICULAR DESTRUCTION THAT CONSISTS OF A SINGLE SPRING OF RECALL FOR BOTH VALVES AND TWO THRUST BEARINGS, EQUIPPED WITH DOSES IN THE FACADE ADJACENT TO THE ROLLER POINT, WHICH IS THE RING BASE . ARCHITECTURE SIFFATTA LEAVES LARGE FREEDOM FOR THE DESIGN OF THE COMBUSTION CHAMBER.
