OVERVIEW
The TD4 dies el engi ne has an Electroni c Dies el Cont rol (EDC) engine management s yst em. The s ys t em i s cont rol led by anECM whi ch is able to monit or, adapt and preci sel y cont rol t he fuel inject ion. The ECM us es mult iple s ens or inputs andprecis ion control of act uat ors t o achieve opti mum performance during all driving condit ions.
The ECM controls fuel deli very t o all 4 cyli nders via a common rai l inject ion s yst em. The common rail s ys t em us es a fuelrai l to accumulate highly press uri zed fuel and feed t he 4, electroni cal ly controlled injectors . The fuel rail i s located i n clos eproximit y to the i njectors, whi ch ass is t s in maint aining full s yst em press ure at each i njector at all t imes .
The ECM us es t he drive by wire pri nci pl e for accelerat ion control. Accelerator pedal demand i s communicat ed t o t he ECM by2 pot ent iomet ers l ocat ed in a thrott le pos it ion sens or. The ECM us es t he 2 s ignals to det ermi ne the pos it ion, rat e ofmovement and di recti on of movement of t he pedal . The ECM t hen uses t his dat a, al ong wit h ot her engine i nformati on fromother s ens ors, t o achieve the opt imum engine respons e.
