OVERVIEW
The TD4 engine feat ures a Garret t Rotary Electroni c Actuated (REA) variabl e geomet ry turbocharger. The t urbocharger i smounted t o t he exhaus t manifold on the Ri ght -Hand (RH) s ide of t he engine, and secured t o t he cyl inder block wit h abracket . An oil pi pe wit h banjo type fixing i s att ached bet ween an outl et on the RH s ide of t he cyl inder bl ock and the t opof the turbocharger hous ing, and provides pres s uri zed oi l to the t urbocharger beari ngs. An oi l pipe at tached to the bot tomof the turbocharger is connect ed to the oi l pan hous ing, and direct s ret urn oi l from t he t urbocharger i nt o t he oil pan. Aheat shi el d i s ins tal led over the t urbocharger and exhaust mani fold to protect other component s, and t o prevent acci dent alcont act wit h the hot exhaus t component s .
The t urbocharger compri ses a turbi ne and compres sor wheel mounted on a common s haft, enclos ed wit hin a cas t hous ing.The common s haft i s s upport ed on 2 semi -float ing beari ngs . The cast hous ing forms 2 chambers that clos ely s urround thet urbine and compres s or wheel s. The t urbine wheel i s pos i ti oned bet ween the exhaust gas flow from t he engine and t heexhaus t s ys t em. The compress or wheel is pos it ioned in the i ntake air flow bet ween t he air filt er and out let t o t he chargeair cooler.
Duri ng turbocharger operati on, t he t urbine and compres s or s haft may reach s peeds in exces s of 200,000 rpm, and producea charge ai r (boost ) pres s ure of up t o 1.7 bar (25 ps i). A pre-t urbine press ure of 3 bar (44 ps i) and a temperat ure of 800°C(1472°F) may be generated i nsi de t he turbi ne chamber.
A REA is at tached to the compres s or hous ing, and is connect ed via a li nkage t o a rotary adjus ti ng ri ng located wit hi n t het urbine hous ing. The internal circumference of t he rot ary adjus t ing ring hous es a s et of radial variable vanes . The variablevanes are pos it ioned to int ercept t he exhaus t gas fl ow from the engine, ahead of the t urbi ne wheel .

At low engi ne s peed t he volume of exhaust gas l eavi ng the engine is l ow. The vanes are moved toward the cl osed pos it iont o direct t he exhaus t gas fl ow t o t he out s ide edge of t he turbine wheel. The clos ed posi ti on of the vanes creates ares t ri ct ion t o t he gas fl ow and i ncreas es t he gas vel oci ty to the t urbine wheel . The turbi ne wheel s peed is increas ed,cons equent ly producing more charge ai r (boos t pres sure) from t he compres sor.
B - Moderate Engine Speed
As engine s peed and exhaus t gas vol ume increas e, the vanes are moved to the open posit ion t o direct t he exhaus t gasfl ow t oward t he center of the turbi ne wheel . The vanes do not rest ri ct the exhaus t gas flow and therefore exhaus t gasveloci ty is dependant on engine s peed. The t urbi ne wheel s peed is maintai ned due to the i ncreas ed velocit y of t he gas esleaving t he engine and being di rected t oward the center area of t he t urbine wheel .
C - Maximum Engine Speed
At maximum engine s peed the volume of exhaus t gas leavi ng t he engi ne is hi gh. The vanes are moved toward the full yopen pos i ti on and do not affect t he gas vel oci ty. The exhaus t gas fl ow contacts t he center area of t he t urbine wheel tomaint ain t he t urbine wheel s peed and boos t pres s ure from the compress or.
Over-Boost Pressure
Duri ng periods of medi um t o hard accelerat ion, the turbocharger is requi red t o produce a l imit ed period of over-boos tpres s ure from the compress or to meet the current engi ne fueli ng requirement. The ECM wil l reques t and all ow t he REA t omove t he variable vanes t oward t he clos ed posi ti on t o increas e t he vel oci ty of t he already high-s peed turbine wheel. Theover-boos t condit ion is all owed by t he ECM for t he l imi ted period.
Barometric Pressure Sensor
At high al ti tude t he t urbocharger wi ll functi on normal ly, but due t o t he l ower ambi ent ai r pres sure t he turbi ne andcompres sor may tend t o over-speed. A baromet ri c pres sure s ensor i s located i n t he ECM t o prevent over-boost andposs i bl e engine damage occurri ng under t hes e condit ions. The ECM opens t he vari abl e vanes earlier duri ng t he openi ngphas e to s uit the al ti tude of t he vehi cl e.
T urbocharger Lubrication
The rapi d accelerat ion and decelerat ion demands of t he turbocharger rel y on a s t eady flow of cl ean oil. The oi l suppli ed byt he engi ne lubri cat ion s ys tem provides l ubricati on to the t urbocharger shaft and bearings, whi le al so act ing as a cool antfor t he t urbocharger cent er hous i ng.
To mai nt ain the l ife expect ancy of t he turbocharger, t he engine oil mus t be replenished at regular s ervice i nt ervals wit ht he recommended qual it y and quant it y of oil . The oi l mus t have a free-fl ow t hrough the turbocharger and an unres trict edret urn to t he engine oi l pan.
