OVERVIEW
The TD4 dies el engi ne fuel charging and cont rol s ys tem provides precis e and i nst antaneous fuel del ivery t o t he combust ion

The fuel s yst em features a Bos ch Generat ion 3 common rai l injection s yst em that is moni tored andcont rol led by an engine control modul e (ECM), t o precis ely cont rol the fueli ng st rategy.
Fuel charging is achieved wit h a l ow and hi gh-pres sure fuel s yst em. The l ow-pres s ure fuel s ys tem compris es ;

The fuel charging and control s ys tem provides i nject ion press ures of up to 1800 bar (26,106 psi ). Fi ner at omizati on of theinject ed fuel is achieved wi th the 7 hol e piezo i njectors that are capable of near ins tant aneous res ponse to the ECMcommands , all owing up to 5 individual inject ions per st roke.
The high-press ure fuel pump i s mounted at t he rear of t he cyl inder head and i s dri ven by the exhaust cams haft . A fuel l iftpump i s int egral wit h t he high-pres s ure pump and is therefore al so driven when t he exhaus t cams haft rot ates . The li ftpump creat es suct ion i n the supply line to t he fuel t ank and draws t he fuel from the t ank. The fuel pas s es through the fuelfi lt er and is t hen delivered at lift pump pres s ure to the hi gh-pres sure pump i nlet port .
The advanced high-press ure fueli ng s ys t em enables pil ot inject ions to be delivered ahead of t he main charge of fuel. Thisproduces a s teady fl ame front and creates a progres s ive pres s ure ris e in t he cyl inder s imi lar to that achi eved wit h petrolengi nes. This reduct ion i n combust ion lag between t he i nject ion of fuel and combus tion occurring al lows fuel t o be i njectedwhil e combus t ion i s t aki ng place, creat ing i ncreas ed power and reducing creat ed combus t ion nois e, vibrat ion andhars hnes s (NVH) and emis s ions .

This pos t combus t ion i njecti on proces s caus es fuel to be burnt in the exhaust s ys tem and creates t he high exhaus tgas temperatures that are required to regenerate t he dies el part icul ate fi lt er.
