Knock Sensors
Two knock sens ors are located on the front of t he engi ne and are each s ecured to threaded holes in t he engine cylinderblock wit h a bol t. The knock sens ors are us ed by t he ECM t o monit or combus ti on knocking or vibrati on generat ed byignit ion combus ti on. The knock s ens ors are each connected t o t he ECM via a t wis t ed pai r of wires which reduces electricalint erference di s rupti ng t he si gnal produced.
Each knock s ens or cont ains a pei zo-ceramic crys t al whi ch produces a vol tage when an ext ernal force appli es pres s ure orload on it . W hen t he engi ne is runni ng, compres s ion waves produced by t he combus t ion proces s, creat es pres sure waveswhich pas s t hrough the engine cyli nder bl ock. Thes e press ure waves are detected by the knock s ens ors and the defl ect ionof the crys t al caus ed by the pres sure waves caus es the sens ors t o produce an out put s ignal. The s i gnals are pas s ed to theECM whi ch compares them wit h s tored mapped s ignal s i n it s memory.
The ECM can t hen det ermine when t he correct combus t ion occurs i n indivi dual cyl inders . If incorrect combus t ion detonat ionis det ect ed, the ECM can retard t he ignit ion ti ming on that cyl inder for a number of combus ti on cycl es . The i gni ti on ti mingwil l be gradually ret urned t o it s opti mal s et t ings. If t he knock is st il l det ected the ECM wi ll i ncreas e t he i nject ion period,which has a cooli ng effect on t hat cyl inder.
The s ignals from the knock s ens ors are us ed i n conjunct ion wi th the CMP sens ors and t he CKP s ens or t o det ermi ne theignit ion cycle and t herefore i dent ify which cylinder is knocki ng. The ECM is programmed to us e i gni ti on maps bas ed on highqual it y 95-98 RO N fuel . If fuel of a poor qual it y s uch as 91 RON i s us ed the engi ne may s uffer from knock (pinking) for aperi od of ti me. The ECM is capable of l earning and adapti ng to the l ow grade fuel and wil l modi fy it s int ernal ignit ionmapping t o compens at e for t he low grade fuel .
