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 .
