FUEL INJECTORS

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.

CAUTION: To avoid damage/malfuncti oni ng of the BMS module, always us e a s uit able body ground point rather thant he bat t ery negat ive terminal when connect ing a s lave power supply.
