Cov txheej txheem kuaj tshwj xeeb yog raws li hauv qab no: (1) Thaum qhov kev sib hloov ceev ntawm cov twj tso kua roj txhaj tshuaj yog 1000 r / min, kho qhov chaw ntawm cov roj txhuam hniav kom cov roj ntim ntawm cov roj txhaj tshuaj yog 50 mm3, Ua kom txoj haujlwm ntawm cov khoom siv roj txhuam hniav tsis hloov pauv, thiab ntsuas cov tshuaj tsuag cuam tshuam ntawm txhua lub qhov ntawm cov roj txhaj tshuaj nyob rau hauv qhov kev sib hloov ceev ntawm cov roj txhaj tshuaj ntawm 800, 1000 thiab 1200 r / min feem; (2) Kho qhov ntsuas lub rooj zaum ntawm lub twj tso kua mis txhaj tshuaj kom lub zog ntawm cov roj txhaj twj tso kua mis khiav ruaj khov ntawm 1000 r / min, kho qhov chaw ntawm cov roj txhuam hniav, thiab ntsuas cov tshuaj tsuag cuam tshuam ntawm txhua lub qhov. cov roj injector thaum cov roj ntim ntawm cov roj txhaj tshuaj yog 50, 60 thiab 70 mm3 / voj voog.
Txhawm rau kom ua tau raws li cov cai nruj CO: emission regulation thiab txo cov phiaj xwm tsis sib haum xeeb ntawm nitrogen oxide (NO.) thiab soot emissions, nws yog ib qho tsim nyog los tsim cov chaw tsim hluav taws xob zoo. Nws yog ib qho kev sib tw rau cov tshuab hluav taws xob kom ua tau raws li tam sim no thiab yav tom ntej European emissions qauv. High tso pa roj recirculation (EGR) tus nqi thiab siab booster siab tuaj yeem txhim kho qhov tsis sib haum xeeb ntawm NO thiab soot emissions ntawm diesel xyaw nyob rau hauv ib feem ntawm kev ua haujlwm. Qhov zoo tshaj plaws kev txhaj tshuaj zoo yog ua ke nrog cov qauv kev txhaj tshuaj digital kom txo tau cov pa phem thiab cov suab nrov combustion. Matsumoto et al. tau pom tias optimizing roj txhaj tshuab yog ib qho tseem ceeb ntawm kev ua tiav cov hom phiaj no. Lub hom phiaj ntawm kev tshawb fawb tsis tu ncua yog txhawm rau ua ke cov kev hloov pauv siab rau hauv lub tshuab hluav taws xob diesel ntawm cov neeg caij tsheb kom ua tiav cov qauv kev txhaj tshuaj zoo nrog tib qhov nyuaj ntawm qhov system.
