Isitofu soBuchule seDizili sokuSebenzisa i-A6510702787 Isitofu sikaLoliwe esiQhelekileyo sezahlulo zeNjini yeMercedes-Benz

1. Umahluko phakathi kwamandla kunye netorque

Kwiimeko eziqhelekileyo, i-cylinder stroke ye-injini yepetroli ifutshane. Isizathu sokuba olu yilo lwamkelwe ngokupheleleyo kukunyusa isantya esiphezulu se-injini, ukuze kuqhume amandla amaninzi. Ngokuchasene noko, ii-injini ze-diesel zihlawula ingqalelo ngakumbi kwi-torque yesithuthi, kwaye i-cylinder stroke imiselwe ukuba ibe yinde, enokunciphisa isantya sesithuthi kwaye ikhulise ngcono i-torque. Ke ngoko, esi sesona sizathu sokuba kutheni izithuthi ezibaleka endleleni, iiSUV, iilori, njl.njl zonke zikhetha i-oyile ye-diesel injini njengomthombo wamandla azo.

2. Uqoqosho lwamafutha

Okubizwa ngokuba yi-fuel economy, eyona nto i-intuitive uthelekiso kukuthelekisa ukusebenza kakuhle kweenjini ezimbini ekuguquleni amandla ashushu kumandla omatshini. Nangona kunjalo, ngenxa yeeyantlukwano ezithile kwitekhnoloji ye-injini evela kubavelisi abahlukeneyo, kukho iiyantlukwano ezithile ekusebenzeni kokuguqulwa kwamandla obushushu kwiinjini. Okwangoku, ukuguqulwa kokusebenza kakuhle kwe-injini yemoto ibisoloko iyingxaki. Ukusebenza kakuhle kwe-thermal yeenjini ezininzi zepetroli kunokufikelela kuphela malunga ne-40%. Kuphela kukuguqulwa kwe-thermal esebenzayo yeenjini eziveliswe ziimpawu ezifana ne-Nissan kunye ne-Mazda ezinokudlula i-40%. Ngakolunye uhlangothi, kwiinjini zedizili, ukuguqulwa okuncinci kwe-thermal kungaphezulu kwe-35%, kwaye kulula ukudlula i-40%. Kukho nezinye iinjini ezinobushushu obungadlula kuma-45%. Ngoko ke, ukusebenzisa umlinganiselo ofanayo wamafutha, i-injini ye-diesel inokuguqula amandla amaninzi ashushu abe ngamandla omatshini, nto leyo ethetha ukuba iyonga kakhulu amafutha.

Ukongeza, ukusebenza kakuhle kwe-thermal yeenjini zepetroli kukwanxulumene ngokusondeleyo nokwakhiwa kwepetroli. Ukusuka kwimbono yeekhemikhali, i-petroli kunye ne-diesel yenziwe ngama-athomu amancinci, kwaye kwi-molecule ye-hydrocarbon compound, kukho malunga ne-8-10 iamolekyu zepetroli. iiathom zekhabhoni, ngelixa iimolekyuli zedizili zinokufikelela kwi-12-15 iathom zekhabhoni. Okukhona uphezulu umxholo we-carbon athom, kokukhona amandla aqulethwe emva kokutsha. Ngoko ke, ukufumana amandla afanayo, injini yepetroli kufuneka ifake amafutha amaninzi kune-injini ye-diesel, kwaye ukusetyenziswa kwamafutha kuya kuba phezulu.

 3. Ukuthembeka kwe-injini kunye nokhuseleko

Ubomi benkonzo ye-injini ihambelana ngokusondeleyo nesantya sokujikeleza. Ukuphakama kwesantya sokusebenza, bufutshane ubomi benkonzo. Umzekelo, i-injini esetyenziswa kwiimoto zomdyarho ze-F1 inesantya esingama-3,000 rpm, kwaye isantya se-injini esiphakathi singaphezulu kwe-15,000 rpm xa i-injini isebenza, ngoko ke ithatha imidyarho embalwa kuphela ukuba injini ithunyelwe kude iyokulahla. . Ukubuyela kwinyani, iinjini zedizili zihlawula ingqalelo ngakumbi kwitorque ephantsi, ngoko xa amandla afanayo efikelela kwisantya esifanayo, isantya senjini yedizili sisezantsi. Ukongeza, nakwesona santya siphezulu isantya se-injini ye-diesel ngokuqhelekileyo asidluli kwi-4500 rpm, ngelixa i-injini yepetroli inesantya esiphezulu se-6500 rpm ukuze ikhuphe amandla angakumbi ehashe. Ke ngoko, iinjini zedizili ezine-rpm esezantsi zithembeke ngokwendalo.

Idizili ayiguquguquki kwaye akulula ukuyitshisa kubushushu obuqhelekileyo bokusebenza. Ngoko ke, xa kusenzeka ingozi ye-injini ye-diesel, ithuba lokuvutha kwesithuthi ngokuzenzekelayo lincinci kakhulu. Ngokungafaniyo nesithuthi sepetroli, xa itanki yamafutha ivuza, kuphela yintlantsi encinci enokuyitshisa. Ngoko nangoko ilayita yonke isithuthi.
