OVERVIEW
The TD4 engine i nt ake air s yst em provides fi lt ered and pres s uri zed ai r to the engine cyli nders , to promote compl etecombus t ion of t he inject ed fuel under al l engine condit ions .
A di rt y air i nt ake duct i s located behind the Left -Hand (LH) front fender and is connect ed to the ai r fi lt er hous ing. Air isdrawn into the i ntake air duct and direct ed through an oil impregnat ed repl aceable fil ter element , locat ed wi thi n the ai rfi lt er hous ing. The filt ered i ntake air i s t hen direct ed through t he clean ai r duct t o the compress or s ide of t he turbocharger.
The clean air duct is manufact ured t o i ncorporat e 4-quarter wave t ubes and a connection to the crankcas e venti lat ions ys t em. The quarter wave t ubes reduce the Noi se, Vi brati on and Hars hnes s (NVH) levels creat ed by t he air t raveli ngt hrough the duct. The connect ion t o t he crankcas e vent il ati on s ys t em al lows environment al ly harmful gas es and vapors tobe drawn from t he engine crankcas e, and int o t he cl ean air duct . The gases and vapors are mi xed wit h t he fi lt ered i ntakeair and burned i n t he cyl inders .
The t urbocharger compres ses and di rects the press uri zed hot i ntake air t hrough a large bore connecti ng hos e to t he chargeair cooler. The ai r pas s es through the charge ai r cooler and i s s ubs equent ly cooled t o i ncreas e t he i nt ake air densi ty. Theoutput s ide of t he charge air cool er direct s the cool dens e ai r through a large bore connecti ng hose to the el ect ronict hrott le and intake mani fold, where the ai r is then dis t ri but ed via the i ntake manifold ports t o t he i ndi vi dual enginecyl inders .
Exhaus t gas via t he Exhaus t Gas Reci rculat ion (EGR) sys t em i s als o direct ed i nt o t he int ake air s yst em t o reduce Oxi des OfNit rogen (NOX) emis s ions . A pipe connect s t he EGR valve l ocat ed at the Ri ght -Hand (RH) s ide of t he engine, to the i ntakemanifold l ocat ed at the Left-Hand (LH) s ide of t he engine. The exchange of exhaust gas i nto t he i nt ake manifold i scont rol led by t he Engine Control Modul e (ECM) during cert ain engine operat ing conditions.For addit ional informat ion, refer t o: Engi ne Emis s ion Cont rol (303-08B Engi ne Emis s ion Cont rol - TD4 2.2L Di esel ,Des cript ion and Operat ion).
Electroni c s ens ors are s t rat egi cal ly l ocat ed around t he int ake ai r s ys t em and const antl y provide i nformat ion of IAT, MAFand MAP t o t he ECM. Thi s i nformat ion i s proces sed and us ed by t he ECM for adjust ing engi ne performance to meet thecurrent operat ing condi ti ons , and driver demands .For addit ional informat ion, refer t o: Electroni c Engi ne Controls - 2.2L Dies el (303-14 El ect ronic Engine Cont rols - 2.2LDies el, Des cript ion and Operat ion).

The TD4 cylinder head and int ake mani fol d are des igned t o opti mize level s of s wirl acros s t he engines s peed range, andprovide a high volume of ai r int o the cyli nders . The intake mani fold is des igned wi th a lower row of 4 heli cal s wirl ports ,and an upper row of 4 fil li ng port s wit h port -deacti vat ion device. The 8 port s are seal ed to the cyli nder head and s truct uralcamshaft cover mati ng port s wi th a s haped s ealing ri ng. The heli cal s wirl port is configured t o creat e opti mum s wi rl forefficient combus t ion; whil e t he fi ll ing port i s provided t o s upply high vol umes of ai r wit hout di s turbi ng in-cyl inder s wi rl . Theint ake manifol d port de-act ivati on devi ce is controlled by the ECM.For addit ional informat ion, refer t o: Electroni c Engi ne Controls - 2.2L Dies el (303-14 El ect ronic Engine Cont rols - 2.2LDies el, Des cript ion and Operat ion).
Each cyli nder i s s uppl ied ai r through t he heli cal s wirl port, and when act ivated, through the fil ling port. The heli cal s wi rlport i s always open and direct s air from the intake mani fold lower port at a t angent i nt o t he combust ion chamber. Thefi ll ing port is normal ly cl os ed, and is onl y opened during cert ain engine operat ing condit ions by t he ECM. W hen opened t hefi ll ing port di rects ai r from t he i nt ake manifold upper port, and t hrough t he curved int ake tract s int o t he combus t ionchamber. The int ake t ract s are cas t wit h t he s truct ural cams haft cover, and join t he i nt ake manifold upper fi lli ng port s t ot he cyl inder head machined fil ling ports .
At low engi ne loads gas fl ow i s s o low that t he fi ll ing port is clos ed off. This has t he effect of rai s ing gas velocit y throught he hel ical port and increas ing i n-cylinder s wirl to t he opti mum rat e. To avoid the ris k of t he high gas flow creati ngexces s ive s wirl, t he ECM opens the fi lli ng port under hi gh gas-fl ow condi ti ons to maint ai n consi st ent opt imum s wi rl acros st he engi nes operat ing range.
