Katswiri Wopanga Mafuta a Dizilo Injector A6510702787 Common Rail Injector wa Mercedes-Benz Engine Injector

1. Kusiyana pakati pa mphamvu ndi torque

Nthawi zonse, silinda ya silinda ya injini ya petulo imakhala yayifupi. Chifukwa chomwe mapangidwewa amatengera ndikuwonjezera liwiro lalikulu la injini, kuti aphulike mphamvu zambiri. M'malo mwake, injini za dizilo zimayang'anira kwambiri torque yamagalimoto, ndipo silinda ya silinda imakhala yayitali, yomwe ingachepetse liwiro lagalimoto ndikukulitsa makokedwe. Chifukwa chake, ichi ndichifukwa chake magalimoto olemetsa kwambiri, ma SUV, magalimoto, ndi zina zambiri amasankha mafuta a injini ya dizilo ngati gwero lawo lamagetsi.

2. Mafuta amafuta

Zomwe zimatchedwa chuma chamafuta, kufananitsa kowoneka bwino ndikufanizira magwiridwe antchito a injini ziwiri pakutembenuza mphamvu yotentha kukhala mphamvu yamakina. Komabe, chifukwa cha kusiyana kwina kwaukadaulo wa injini kuchokera kwa opanga osiyanasiyana, pali kusiyana kwina mu mphamvu yamagetsi yosinthira ma injini. Pakadali pano, kusintha kwachangu kwa injini zamagalimoto kwakhala vuto nthawi zonse. Kutentha kwamafuta ambiri amafuta kumatha kufika pafupifupi 40%. Only matenthedwe dzuwa kutembenuka kwa injini opangidwa ndi zopangidwa monga Nissan ndi Mazda akhoza upambana 40%. Kumbali ina, kwa injini za dizilo, kutembenuka kocheperako kwamafuta kumakhala pamwamba pa 35%, ndipo ndikosavuta kupitilira 40%. Palinso injini zina zomwe kutentha kwawo kumatha kupitirira 45%. Choncho, pogwiritsira ntchito mafuta omwewo, injini ya dizilo imatha kusintha mphamvu zambiri zotentha kukhala mphamvu zamakina, zomwe zikutanthauza kuti ndiyopanda mafuta.

Kuphatikiza apo, kutsika kwamafuta ochepa a injini zamafuta kumagwirizananso kwambiri ndi kapangidwe ka mafuta. Kuchokera kumalingaliro amankhwala, mafuta ndi dizilo amapangidwa ndi mamolekyu ang'onoang'ono, ndipo pa molekyulu iliyonse ya hydrocarbon, pali mamolekyu amafuta a 8-10. maatomu a carbon, pamene mamolekyu a dizilo amatha kufika maatomu a carbon 12-15. Kuchuluka kwa atomu ya carbon, mphamvu yomwe imakhalapo pambuyo poyaka. Chifukwa chake, kuti akwaniritse mphamvu zomwezo, injini ya petulo imafunika kubaya mafuta ambiri kuposa injini ya dizilo, ndipo mwachilengedwe mafutawo amakhala okwera kwambiri.

 3. Kudalirika kwa injini ndi chitetezo

Moyo wautumiki wa injini umagwirizana kwambiri ndi liwiro lozungulira. Kukwera kwa liwiro la ntchito, kumachepetsa moyo wautumiki. Mwachitsanzo, injini yomwe imagwiritsidwa ntchito m'magalimoto othamanga a F1 imakhala ndi liwiro la 3,000 rpm, ndipo liwiro la injini limakhala pamwamba pa 15,000 rpm injini ikugwira ntchito, motero zimangotengera mipikisano yochepa kuti injini itumizedwe kuti ikatenge zidutswa. . Kubwerera ku zenizeni, injini za dizilo zimayang'anitsitsa kwambiri torque yotsika, kotero mphamvu yomweyi ikafika pa liwiro lomwelo, liwiro la injini ya dizilo limatsika. Komanso, ngakhale pa liwiro lapamwamba injini dizilo liwiro zambiri si upambana 4500 rpm, pamene injini mafuta ali ndi liwiro pazipita osachepera 6500 rpm kuti Finyani mphamvu ndiyamphamvu. Chifukwa chake, ma injini a dizilo okhala ndi rpm yotsika amakhala odalirika mwachilengedwe.

Dizilo simasinthasintha ndipo sikophweka kuyatsa pa kutentha kwanthawi zonse. Chifukwa chake, ngozi ya injini ya dizilo ikachitika, mwayi woti galimotoyo imangoyaka yokha ndi yaying'ono kwambiri. Mosiyana ndi galimoto ya petulo, thanki yamafuta ikangowotchera, kamoto kakang'ono kokha kamayatsa. Nthawi yomweyo amayatsa galimoto yonse.
