Simba reinjini yekupisa mukati uye mota yemagetsi - nzira yekududzira? Tarisa kana nhamba ye km ndiyo inonyanya kukosha!

Iyo inonyanya kukosha manhamba paramita yemota injini simba uye simba. Ndeupi musiyano uripo pakati pepfungwa idzi? Simba rinoratidza kuti zvinhu zvinodyidzana sei. Chikamu chayo chinonzi newtons. Simba, kune rumwe rutivi, rinoratidza chiyero chebasa kune nguva yainotora kuzviita. Mune injini, izvi zvakakosha zvine simba rakakura pakutenderera kweyuniti. Nzira yekuverenga sei injini simba? KW ndicho chikamu chichabatsira. Isu tinopa iwo nuances uye tinopa zano kuti ungaverenge sei simba redhiraivha unit!

Injini simba - chii?

Zvinowanzotaurwa kuti motokari ine imwe mhando injini ine 100 kana 150 horsepower. Nekudaro, aya mayunitsi haasi chikamu cheSI system yemayuniti uye anofanirwa kuverengerwa kubva kilowatts (kW). Naizvozvo, mumotokari data sheet uchawana ruzivo rwekuti vangani kW injini ine, uye kwete bhiza. Simba reinjini ndiyo huwandu hwebasa uye inoyerwa pane drive shaft yeyuniti kana pamavhiri (somuenzaniso, pane dynamometer). Nomuzvarirwo, kuyerwa kwakananga pane injini kunopa kukosha kwepamusoro zvishoma. Mukuwedzera, iyi haisi kukosha nguva dzose, sezvo zvichienderana nekutengesa.

Nzira yekuverenga sei mota simba (kW)?

Kuti uverenge simba remota mu kW, maitiro maviri anodiwa:

• torque;
• injini kumhanya.

Ngatiti iwe unoda kutenga injini inovandudza 160 Nm ye torque pa 2500 rpm. Kuti uwane simba mu kilowatts, unofanirwa kuwanza maitiro aya uye kupatsanura ne 9549,3. Uchawana kukosha kwei? Zvinoitika kuti injini panguva ino yekutenderera inobudisa simba re 41,88 kW. Wedzera mhedzisiro ne1,36 kuti uwane kukosha mu km. Izvi zvinopa anenge 57 hp.

Yakatemerwa simba reinjini yekupisa yemukati - inopihwa sei?

Rated simba rinoratidza simba rinobatsira. Iyo inogara ichiyerwa padhiraivha shaft yeinjini, uye kana iri mukati meinjini yekupisa inoratidzwa mu kW kana hp. Ndapota cherechedza kuti injini simba haisi kukosha nguva dzose. Izvo zvakanyanya zvinoenderana nekumhanya kweinjini uye torque. Ndokusaka, semuenzaniso, peturu uye dhiziri mayuniti ane akasiyana zvakanyanya maitiro ekuita, uye hazvina musoro kukora yekutanga kusvika pakumhanya kwakanyanya. Nzira yekuinzwisisa?

Simba rekudyara remagetsi emagetsi uye mukati memoto injini uye pesvedzero yekuchinja

Ngatidzokerei kune tsananguro ye torque. Iri ndiro simba rinoratidzwa mu newtons. Inotaura nezve kushandura nzvimbo yemuviri weimwe misa ine kumwe kukwidziridzwa. Diesel injini dzine yakawanda torque muzasi rpm renji. Vanowanzosvika pakukosha kwavo kwepamusoro muhuwandu hwe1500-3500 rpm. Ipapo unonzwa chimwe chinhu chakaita sokutsikirirwa pachigaro. Urwu rudzi rwekutevedzana kunodzikira sezvo mari ikawedzera kupfuura iyi muganhu.

Simba uye torque yepeturu injini

Injini dzepeturu dzakasiyana zvachose, kunyangwe nekushandisa turbocharger, misiyano iyi inodzimwa. Ivo vanowanzo svika yavo yakakura torque yakatenderedza 4000-5500 rpm. Ndokusaka mayuniti anoshuvira peturu ane simba guru reinjini munzvimbo dzepamusoro dzemarevolutions uye saka mhanyisa mazviri.

Chii chimwe chinodiwa - hp. kana Nm?

Iwe unogona kunge wakacherechedza kuti tsanangudzo dzemotokari dzinowanzova nemashoko pamusoro pesimba reimwe injini. Idzi dzinowanzo tenderera uye "dzakanaka" nhamba. Semuenzaniso, ega ega VAG dhiziri mayunitsi pane imwe nguva aive ne90, 110, 130 uye 150 hp. Izvi zvakabatsira kuwedzera kufarira mumotokari imwe neimwe zvinoshamisa. Zvisinei, mukushanda kwemazuva ose, nokuda kwekufamba kwakanaka, chinhu chinonyanya kukosha hachisi simba rejini, asi torque yayo. Sei?

Sei torque dzimwe nguva ichiti kupfuura simba injini?

Iko kuchinjika kweiyo unit kunoenderana nekuti ingani Nm yakapihwa injini ine uye mune ipi yekumhanyisa renji iyo inoburitsa kukosha kwayo kukuru. Ndicho chikonzero nei injini diki dzakagadzirirwa turbocharger. Nekuda kweizvi, havafanirwe kuchengetwa nekumhanya kwakanyanya kuitira kuti vawane akakodzera ekushandisa parameter. Ichi chinhu chinobatsira kana wakaremerwa zvakanyanya, senge kana uchityaira uine mikwende yakawanda, overtake kana kutyaira uchikwidza. Zvadaro zviri pachena kuti injini duku peturu inofanira kuchengetwa mukati 3-4 zviuru. rpm kuitira kushanda zvakanaka. Diesel, kune rumwe rutivi, haadi iyo RPM yakawanda kubata mamiriro akaomarara zvakanaka. Pakusarudza motokari, teerera kwete chete kuti yakawanda sei bhiza muenzaniso wakapiwa. Onawo mumhando ipi iyo inovandudza simba uye torque. Izvo zvinoitika kuti mayuniti maviri ane simba rimwechete ane akasiyana zvachose maitiro ekuita, nekuti anoshanda mune akasiyana spidhi renji. Saka yeuka kuti injini simba haisi zvose. Inokurumidza uye yakawanda inowanikwa torque ndiyo yakakosha pakufamba kwakanaka.
