OVERVIEW
The evaporat ive emis si on (EVAP) control s ys tem reduces the l evel of hydrocarbons releas ed int o the at mos phere by fuelvapor venti ng from t he fuel t ank. The s yst em compris es a charcoal canis ter, purge valve and i nt erconnect ing vent pipesand hoses .
Fuel vapor is generated by the fuel in t he t ank and the amount of vapor produced increas es as the fuel heat s up. Fuelvapor can flow freely to the charcoal canis t er vi a the tank venti ng sys t em. The venting s yst em cons is ts of roll over val vesand a l iquid vapor s eparat or mounted i nternal ly i n t he tank and t hen ext ernall y via a breather l ine. The breather li neall ows the fuel vapor to fl ow t o t he charcoal cani st er.
On NAS vehicl es the vapor generat ed in the fuel tank duri ng refuel ing flows wit hout res t ri ct ion to t he charcoal canis ter.
On al l vehicles except NAS, t he vapor i s res t ri ct ed in it s path to t he charcoal canis ter but can fl ow freely during t herefuel ing operat ion t o at mos phere, vi a t he fi ller opening.
The vapor pas ses i nto the charcoal canis t er where it i s abs orbed and s tored by the charcoal. Becaus e t here i s a l imi t t o theamount of vapor the canis t er can contain, t he fuel vapor i s purged from the canis t er when t he engine i s running andburned i n the engi ne.
PRINCIPLES OF OPERATION
Charcoal Canister
The charcoal cani s ter cont ains a bed of acti vat ed charcoal or carbon. The charcoal is produced us ing s peci al manufact uri ngt echniques to treat the charcoal wit h oxygen. The oxygen t reatment opens up mi ll ions of pores between t he carbon at omsres ult ing i n a hi ghl y porous charcoal wi th a very l arge effecti ve surface area which is capable of abs orbing l arge quanti ti esof fuel vapor. Once treat ed t he charcoal is known as 'act ivated' carbon or charcoal. The charcoal canis t er on NAS vehi cl esus es a higher grade charcoal t o meet t he requirement s of t he emis s ion regul ati ons .
On-board Refueling Vapor Recovery
To meet On-board Refueli ng Vapor Recovery (O RVR) requi rement s, t he fuel t ank and associated component s are desi gnedt o mi ni mize fuel vapor los s duri ng refuel ing. This i s achi eved by prevent ing fuel vapor from t he fuel t ank venti ng direct ly tot he atmos phere. Ins t ead fuel vapor is di rected into the Evaporati ve Emis s ion (EVAP) canis t er where i t is s t ored beforebeing purged at i ntervals int o the engi ne’s int ake mani fol d.
Duri ng vehi cl e refueling the narrow fuel-fi ller-t ube below t he fuel -di spens er nozzle regi on, provi des a l iquid s eal agai ns tt he escape of vapor. A check valve al so locat ed i n the fi ller-t ube opens t o i ncomi ng fuel t o prevent spl as h back.
As t he fuel t ank fil ls , fuel vapor i s rout ed to the EVAP canis t er's charcoal fi lt er, where i t is abs orbed by t he charcoal 'sact ivat ed granules . The hydrocarbons from the fuel vapor are retai ned wit hin t he cani s ter, al lowing onl y puri fied ai r to berel eas ed t o at mosphere through the canis ter's vent pipe. The hydrocarbons s t ored in the canis t er are purged at i nt ervalsint o t he engi ne for combust ion.
The EVAP cani st er purge valve i s located i n t he engi ne compart ment . The Engine Control Modul e (ECM) operat es the val vet o purge fuel vapor from t he EVAP cani st er int o t he engi ne for combust ion. Purge rates (the ext ent that the purge valveopens ) are det ermined by t he engi ne operati ng condi ti ons . The purge rates are adjus ted t o mai ntai n vehi cl e dri vingcharact eri st ics and exhaus t emi ss i ons at opt imum levels . Engi ne operati ng condi ti ons that affect t he purge rate are:
s peed and load,engi ne cool ant temperat ure,t ime from engine s t art-up,clos ed loop fuel ing
Owi ng to the l imi ted st orage-volume of the EVAP canis ter:
NAS deri vat ive - 2.5 l it erROW derivat ive - 0.7 li ter
t he charcoal fi lt er is conti nuall y regenerat ed.
Regenerat ion is achieved when the engine is runni ng, by drawing ai r through t he EVAP cani s ter, vi a t he vent pipe, i nt o t heengi ne for combus ti on.
Fuel Tank Leakage Monitoring
Fuel t ank leakage monit oring i s a l egis lat ive requirement for NAS vehicles . The monit ori ng sys t em peri odi cal ly checks t heEVAP s ys t em and fuel t ank for l eaks when t he i gni ti on is off.
The monit ori ng s ys t em compri ses the previ ous ly des cri bed components of t he EVAP s ystem wit h the foll owing addit ionalcomponents :
air pump, anddust fil ter
The pump i s connected t o t he vent pi pe of the EVAP canis t er and i ncorporates :
a Pos it ive Temperat ure Coefficient (PTC) heat ing element ,

change over val ve, anda reference ori fi ce
The pump i s only operat ed when the ignit ion i s 'off' and as cont rol led by t he ECM. The ECM al so monit ors t he pumpoperati on and t he change over valve for fault s . The dus t fil ter prot ect s t he pump from the i ngres s of mois t ure and foreignpart icles .
The fuel t ank leakage moni toring t est i s performed if t he foll owing fact ors are present:
t he engi ne has been operat ing for at leas t 10 mi nut es and is now at res t,t he fuel in the t ank is bet ween 15 and 85 percent vol ume,t he ambient temperat ure is above 0°C (32°F) and les s t han 40°C (104°F),t he engi ne has not been s t art ed for at leas t 3 hours prior t o it s l as t operat ion
The pump i s operated t o press uri ze the fuel tank and t he electrical current used to operat e t he pump i s meas ured wi th thechange-over val ve in di fferent s tat es. A comparis on of the current draw in each s tate indi cat es the degree of any fuelvapor l eak; i f appropriat e the ECM records t he appropri ate Di agnos t ic Trouble Code (DTC).
