The tes ts are us ed t o categori ze the i njectors, the difference i n t he inject ion analys isres ult s i s transl ated t o a 10-digit al pha-numerical code t hat is s t amped on t he inject or cas ing.
The 10-digi t codes are s tored in t he ECM memory al ong wit h t he corres pondi ng cyl inder numbers for each inject or, and anengi ne performance s oft ware map. The ECM recogni zes each inject or 10-digit code and adapts t he operat ion of eachinject or to provi de s imi lar i nject ion press ures and quant it y of del ivered fuel for the current operati ng condit ion, inaccordance wit h t he programmed s oft ware map.
The inject or body contai ns a s tack of piezo-electric crys t als mount ed above a cont rol pis ton. The piezo crys t al s areact uated by a s uppl y vol tage from t he ECM. The control pis ton i s s eparated wit h a hydrauli c chamber t hat acts to operat et he needle val ve via a domed pis ton and control dril li ngs . The hydrauli c chamber compens ates for temperat ure changeswit hin the i njector as sembl y, and al so allows the i njector t o operate wit h a cons tant reacti on ti me, even aft er numerousoperati ons .
The hydraulic chamber eliminates t he requi rement for contacti ng moving part s wi thi n t hi s t ype of i njector. In ot her types ofinject or thes e cont act parts will wear, increasi ng t he reacti on ti me of t he inject or and subs equentl y affect ing the enginesperformance and emis s ions .
On t he vehicle, the hydraul ic chamber i s mai nt ained by a 10 bar (145 ps i) check valve locat ed in the injector l eak-off pipejuncti on.
Due t o t he Bosch Generat ion 3 technol ogy and the i njector hydraulic chamber, t he inject ors will operat e wi th a nearins t ant aneous respons e ti me t o ECM commands . This provi des a fi ner at omizat ion of t he inject ed fuel, and al lows t he ECMt o precis ely control the actuat ion peri od of the injector. During certain engi ne operati ng condit ions , each injector i s able t odeliver a s equence of up t o 5 injecti ons during a s ingle i njecti on cycle. The s equence for an injecti on cycle of 5 indivi dualdeliveries is as fol lows :

The pil ot injecti on phas e is deli vered ahead of t he mai n charge of fuel t o produce a s teady flame front , and create aprogres s ive pres s ure ri se in t he cylinder. The pi lot inject ion phas e reduces the l ag between t he i nject ion of fuel andcombus t ion occurri ng, al lowing the remaining charge of fuel t o be injected whi le combus ti on is taking pl ace.
