N'chifukwa chiyani magalimoto amakhala ndi nthawi zosiyanasiyana zosinthira mafuta?

Kusintha kwamafuta pamagalimoto kumatengera mtundu, mtundu, ndi chaka chagalimoto yanu. Mafuta oyenera komanso momwe galimoto imagwiritsidwira ntchito ndizofunikira.

Kusintha mafuta ndi imodzi mwazinthu zofunika kwambiri zokonzetsera magalimoto, ndipo pali zifukwa zingapo zomwe magalimoto amakhala ndi nthawi zosiyanasiyana zosinthira mafuta, kuphatikiza:

• Mtundu wa mafuta omwe amagwiritsidwa ntchito mu crankcase
• Mtundu wa ntchito yomwe galimotoyo imagwiritsidwa ntchito
• mtundu wa injini

Mafuta opangira, monga Mobil 1 Advanced Full Synthetic Motor Oil, adapangidwa kuti azigwira ntchito pa kutentha kwakukulu. Amapangidwanso kuti asawonongeke kwa nthawi yayitali kuposa mafuta amtundu wamba. Chifukwa idapangidwa kuti ikhale yotalikirapo, imakhalanso ndi nthawi yosiyana yosinthira mafuta kuposa mafuta oyambira, ngakhale amagawana mafotokozedwe a SAE (Society of Automotive Engineers).

Kumene mumagwira ntchito zimakhudza

Momwe mumayendetsera galimoto yanu ndi momwe mumayigwiritsira ntchito zidzakhala ndi zotsatirapo zina pa nthawi ya kukhetsa. Mwachitsanzo, ngati galimoto yanu ikugwiritsidwa ntchito kumalo otentha, owuma komanso afumbi, mafuta amatha kutha mofulumira. Si zachilendo kuti ngakhale mafuta ofunikira kwambiri amalephera pasanathe miyezi itatu pansi pazimenezi. Ichi ndichifukwa chake akuluakulu ena amagalimoto amalimbikitsa kusintha mafuta anu kamodzi pamwezi ngati mumagwira ntchito m'chipululu ndikuyendetsa kwambiri.

Mofananamo, ngati mumayendetsa m'malo ozizira kwambiri, mafuta a galimoto yanu amathanso kutsika mofulumira. Chifukwa injiniyo singafike kutentha kwanthawi zonse chifukwa cha kuzizira kwambiri, zonyansa zimatha kudziunjikira mumafuta. Mwachitsanzo, m’madera ena, si zachilendo kuti kutentha kukhale pansi pa 0°F kwa nthawi yaitali. Pakutentha kopitirizabe kumeneku, maunyolo a ma molekyulu a parafini omwe mwachibadwa amakhala m’mafuta amayamba kulimba, n’kupanga unyinji wa matope mu crankcase womwe umafuna kukhala olimba. Mufunika chotenthetsera chipika kuti mafuta viscous mu mikhalidwe imeneyi. Kusiyidwa osatenthedwa, mumakhala pachiwopsezo chowononga injini mpaka injiniyo ikatentha kwambiri kotero kuti mafutawo amakhala owoneka bwino.

Chochititsa chidwi n'chakuti, mafuta opangira, monga momwe amapangidwira, amatha kukhala owoneka bwino kwambiri pa kutentha kwambiri. Komabe, ngakhale mafuta opangidwa amafunikira thandizo pamene kutentha kwa injini za gasi kuyandikira -40 ° F kwa nthawi yayitali.

Ma injini a dizilo ali ndi zosowa zawo

Ngakhale kuti injini za dizilo ndi mafuta zimagwira ntchito pa mfundo zofanana, zimasiyana mmene zimapezera zotsatira zake. Ma injini a dizilo amagwira ntchito mothamanga kwambiri kuposa ma injini a gasi. Madizilo amadaliranso kutentha kwambiri ndi kupanikizika mu silinda iliyonse kuti aziwotcha mpweya / mafuta osakaniza omwe amabayidwa kuti apereke mphamvu. Ma dizilo amagwira ntchito mokakamiza mpaka kupsinjika kwa 25: 1.

Popeza injini za dizilo zimagwira ntchito zomwe zimatchedwa kuzungulira kotseka (zilibe magwero akunja oyatsira), zimakondanso kukankhira zonyansa mumafuta a injini pamlingo wokwera kwambiri. Kuphatikiza apo, zovuta za injini za dizilo zimabweretsa mavuto owonjezera pamafuta. Pofuna kuthana ndi vutoli, makampani amafuta akupanga mafuta opangira injini ya dizilo kuti azitha kupirira kutentha, kuipitsidwa, ndi zinthu zina zokhudzana ndi kuyatsa. Nthawi zambiri, izi zimapangitsa mafuta a dizilo kukhala olimba kuposa mafuta a injini ya gasi. Nthawi yosinthira mafuta m'ma injini ambiri a dizilo ili pakati pa 10,000 ndi 15,000 mailosi, kutengera wopanga, pomwe injini zamagalimoto zimafunikira kusintha kwamafuta pakati pa 3,000 ndi 7,000 mailosi kutengera mtundu wamafuta. Mafuta amtundu wanthawi zonse amafunikira kusinthidwa pakadutsa mailosi pafupifupi 3,000, pomwe mafuta opangidwa apamwamba amatha kukhala mpaka ma 7,000 mailosi.

Turbocharging ndi nkhani yapadera.

Mlandu wina wapadera ndi turbocharging. Mu turbocharging, mpweya wotulutsa mpweya umapatutsidwa kuchoka kumayendedwe abwino kupita ku chothandizira ndikutuluka mupaipi kupita ku chipangizo chotchedwa compressor. Compressor, nayonso, imawonjezera kuthamanga kwa mbali ya injini kuti mpweya / mafuta osakanikirana omwe amalowa mu silinda iliyonse amawunikiridwa. Kuphatikiza apo, kukakamiza kwamafuta a mpweya kumawonjezera mphamvu ya injini motero mphamvu zake zimatuluka. Turbocharging kwambiri kumawonjezera mphamvu yeniyeni ya injini. Ngakhale kuti palibe lamulo lalikulu la kuchuluka kwa mphamvu zomwe zimatuluka, popeza dongosolo lililonse ndi lapadera, nkoyenera kunena kuti turbocharger imatha kupanga injini ya silinda anayi kugwira ntchito ngati silinda sikisi ndi injini ya silinda sikisi kugwira ntchito ngati eyiti. - silinda.

Kuchita bwino kwa injini ndi kutulutsa mphamvu ndi ziwiri mwazabwino zazikulu za turbocharging. Kumbali ina ya equation, turbocharging imawonjezera kutentha mkati mwa injini. Kutentha kokwezeka kumawonetsa mafuta amtundu wanthawi zonse mpaka pomwe amafunikira kusinthidwa pafupipafupi mkati mwa mailosi 5,000 kuti akhalebe ndi mphamvu ndikupewa kuwonongeka.

Inde, kusintha kwa mafuta kumasiyanasiyana

Chifukwa chake, magalimoto osiyanasiyana amakhala ndi nthawi zosiyanasiyana zosinthira mafuta. Ngati mafuta ali opangidwa mokwanira, nthawi yake yosinthira imakhala yayitali kuposa yosakaniza kapena wamba. Ngati galimotoyo ikugwiritsidwa ntchito kumalo otentha, owuma ndi amchenga, mafuta mu injini yodzaza ayenera kusinthidwa mwamsanga kusiyana ndi malo abwino kwambiri. N'chimodzimodzinso ngati galimotoyo ikugwiritsidwa ntchito kumalo ozizira. Iliyonse mwa mitundu iyi ya ntchito imadziwika ngati ntchito yomwe injini ikugwira ntchito. Pomaliza, ngati injini ndi dizilo kapena turbocharged, mafuta kusintha intervals ndi osiyana.

Ngati mukufuna kusintha mafuta, "AvtoTachki" akhoza kuchita kunyumba kwanu kapena ofesi pogwiritsa ntchito apamwamba Mobil 1 mafuta okhazikika kapena kupanga injini.
