Momwe mungawerengere mphamvu

Mphamvu ya akavalo imadziwika ndi ntchito zomwe zimachitika pakapita nthawi. Mtengo wolondola wamahatchi amodzi ndi mapaundi 33,000 pa phazi pa mphindi. Mwanjira ina, ngati mutakwanitsa kukweza phazi 33,000, XNUMX phazi limodzi mphindi imodzi, mungakhale mukugwira ntchito pa liwiro la mahatchi amodzi. Munthawi imeneyi, mukadatopa kamphindi kakang'ono ka mphamvu yamphamvu ya mahatchi amodzi.

Kusiyana pakati pa mphamvu ndi torque yamagalimoto

Mphamvu za akavalo

Mphamvu ya akavalo imadziwika ndi liwiro ndipo imayezedwa pakusintha kwakukulu pamphindi (RPM). Mphamvu ndizomwe zimakakamiza wopanga magalimoto kuti adziwe momwe angagwiritsire ntchito tachometer komanso amasankha mtundu wa matayala ndi kuyimitsidwa komwe kudzagwiritsidwe ntchito pamagalimoto. Horsepower imayika malire a liwiro lomwe injini ingayendetsere galimoto panthawi yoyendetsa.

Mphungu

Torque imadziwika ndi mphamvu ndipo imayezedwa motsika (grunt) ndikutsimikiziridwa pakusintha kochepa pamphindi (RPM). Torque ndi chomwe chimapangitsa galimoto kuchoka pakupuma kupita kukuyenda kwathunthu. Opanga amasankha mtundu wanji wa kusiyanitsa ndi kufalitsa kuti agwiritse ntchito potengera torque. Horsepower kokha kufulumizitsa kufala; komabe, torque ndi yomwe imapangitsa kuti magiya agwirizane ndi mphamvu zambiri.

Gawo 1 la 4: Kuyeza mphamvu ya injini yamagalimoto

Zipangizo zofunika kuti amalize ntchitoyi

• cholembera ndi pepala
• Buku la Mwini Magalimoto

Gawo 1: Pezani ma torque agalimoto. Mutha kuziyang'ana mumlozera wogwiritsa ntchito ndipo bukhulo lidzakuuzani ma torque.

Khwerero 2: Yang'anani liwiro la injini mu bukhu la eni ake.

3: Chulukitsani mtengo wa torque ndi liwiro la mota. Mudzagwiritsa ntchito fomula (RPM x T)/5252=HP pomwe RPM ndi liwiro la injini, T ndi torque, ndipo 5,252 ndi ma radian pamphindikati.

• Chitsanzo:: 2010 Chevrolet Camaro 5.7-lita umabala 528 Ft-lbs wa makokedwe pa 2650 rpm. Choyamba mumawerengera 2650 x 528. Mupeza 1,399,200 1,399,200 5252. Tengani 266 ndikugawaniza ndi XNUMX ndipo mumapeza mphamvu. Mupeza mahatchi XNUMX.

Ngati mulibe Buku ndipo mukufuna kudziwa mphamvu ya injini, mukhoza onani amene injini ndi galimoto. Mutha kuyang'ana injini ndikuzindikira kuti injiniyo ili ndi masilinda angati kuchokera ku majekeseni ndi ma spark plugs.

Ndiye onani mtundu wa injini waikidwa pa galimoto. Yang'anani mbale yomwe ili pachitseko, cholembera pachitseko cha khoma la chitseko cha dalaivala. mbale Izi zikusonyeza chaka kupanga galimoto, makhalidwe katundu ndi injini kukula. Ngati mulibe mbale ya pakhomo, yang'anani nambala ya galimotoyo. Tengani nambala ndikuphwanya VIN. Mukakhala ndi kuwonongeka kwa VIN, mudzadziwa kukula kwa injini.

Tengani kukula kwa injini ndikuchulukitsa ndi kuchuluka kwa masilindala. Kenako tengani nambalayo ndikuchulukitsa ndi kuchuluka kwa masilindala omwe amagawidwa ndi kukula kwake ndikuchulukitsa ndi 3 pamainjini anthawi zonse kapena 4 pamakina opangira ma torque. Kenako chulukitsani yankho ndi pi. Izi zidzakupatsani mphamvu ya injini.

• Chitsanzo::
  
  

5.7 x 8 = 45.6, 8/5.7 = 0.7125, (0.7125 x 3 = 2.1375 kapena 0.7125 x 4 = 2.85), 45.6 x 2.1375 x 3.14 = 306 kapena 45.6 x 2.85 x 3.14

Makokedwe ndi 306 kwa injini muyezo ndi 408 ndi phukusi makokedwe. Kuti mudziwe mphamvu, tengani galimotoyo ndikuzindikira ma rpm.

Makinawa kufala

• Kupewa: Musanafufuze, onetsetsani kuti mabuleki akugwira ntchito. Galimotoyo ikhala yothamanga kwambiri ndipo mabuleki olakwika apangitsa kuti galimotoyo iziyenda.

Khwerero 1: Khazikitsani mabuleki oimika magalimoto ndikuyambitsa injini. Ikani mabuleki a utumiki njira yonse. Sinthani cholozera chosinthira kupita pa "drive" ndikusindikiza chopondapo cha gasi kwa masekondi 3-5 pamayendedwe otseguka.

Khwerero 2: Pakuthamanga kwathunthu, yang'anani sensor ya RPM. Lembani kuwerengera kwa pressure gauge. Mwachitsanzo, gauge ikhoza kuwonetsa 2500 rpm. Uwu ndiye mtengo wapamwamba kwambiri womwe chosinthira makokedwe amatha kupanga pamakokedwe athunthu a injini.

Kutumiza Kwamanja

Khwerero 1: Tengani galimoto kuti mukayese. Mukasuntha, musagwiritse ntchito clutch, koma onjezerani liwiro la injini mpaka chiwongolero cha gear chigwire.

**Khwerero 2: Chingwe chosinthira chikasintha kukhala giya, yang'anani kachipangizo ka RPM ndikulemba zomwe mukuwerenga.

Mukakhala ndi RPM yopangidwira kuyesa kwa khola kapena kuyesa kutsetsereka, tengani RPM ndi x pa torque, kenako gawani ndi 5252 ndipo mumapeza mphamvu zamahatchi.

• Chitsanzo::
  
  

Liwiro la khola 3350 rpm x 306 Ma injini okhazikika = 1,025,100 5252 195/3350 = 408. Pa injini yokhala ndi torque: Liwiro la khola 1 rpm x 366 = 800 5252, 260/XNUMX = XNUMX

Choncho, injini akhoza kukhala ndi mphamvu ya 195 hp. kwa zida za injini (3" kubowo kuya) kapena 260 hp kwa zida za torque (kuya kwa dzenje 4".

Gawo 2 la 4: Kuyeza mphamvu ya injini pa choyimitsa chamoto

Zipangizo zofunika kuti amalize ntchitoyi

• Wophwanya 1/2 galimoto
• Kuzama kwa micrometer kapena caliper
• Internal micrometer
• Kuyika kwa Micrometer
• cholembera ndi pepala
• SAE/Metric socket yakhazikitsa 1/2 drive
• Telescopic sensor

Ngati muli ndi injini pa injini ndipo mukufuna kudziwa kuchuluka kwa mahatchi omwe amatha kupanga, muyenera kutsatira izi:

Khwerero 1: Chotsani zochulukira zomwe mumadya ndi mitu ya silinda ya injini. Onetsetsani kuti muli ndi poto ngati choziziritsa kapena mafuta atuluka mwadzidzidzi pansi pa injini.

Khwerero 2: Pezani choyezera chamkati kapena choyezera ma telescopic. Yezerani kukula kwa silinda kuzungulira pamwamba, pansi pa bwana wa mphete.

• Chenjerani: Mphepete mwa mphete ndi pamene pisitoni imayima ndi kupanga chitunda pamwamba pa pisitoni pamene pisitoni ikulira mu bore wear.

Khwerero 3: Mukayeza dzenje, tengani ma micrometer ndikupeza micrometer yomwe ingagwirizane ndi kukula kwa chida chomwe chikugwiritsidwa ntchito. Yezerani chida kapena werengani micrometer yamkati kuti mudziwe kukula kwa dzenje. Werengani micrometer ndikulemba muyeso. Mwachitsanzo, kuyang'ana bore pa 5.7 lita Chevrolet chipika kuwerenga za 3.506 pa micrometer.

Khwerero 4: Tengani micrometer yakuya kapena caliper ndikuyang'ana mtunda wa pisitoni yoyima pamwamba ndi pansi pa dzenje. Muyenera kuyeza pisitoni pansi pakatikati pakufa (BDC) komanso pakatikati pakufa (TDC). Werengani kuwerenga kwa geji yozama ndikulemba miyeso. Chotsani miyeso iwiri kuti mupeze mtunda pakati pawo.

Tsopano popeza muli ndi miyeso, muyenera kubwera ndi chilinganizo kuti mudziwe kuchuluka kwamphamvu kwamahatchi omwe injiniyo ipange.

Ndibwino kugwiritsa ntchito njira iyi:

Kukula kwa silinda kumachulukitsa kuya kwa silinda kuchulukitsa kuchuluka kwa masilindala kuchulukitsa tchati cha chitumbuwa.

• Chitsanzo::
  
  

3.506 x 3 x 8 x 3.14 = 264.21

Chitsanzo ichi zachokera 5.7L Chevrolet injini ndi anabowola 3.506, kuya 3 mainchesi, okwana masilindala 8, ndi kuchulukitsa ndi (3.14), kupereka 264 HP.

Tsopano, pisitoni ikakhala yotalikirapo mu injini, m'pamenenso injini imakhala ndi torque yambiri, komanso mphamvu zambiri za akavalo. Ndi ndodo zazitali zolumikiza, injiniyo imazungulira crankshaft mwachangu kwambiri, zomwe zimapangitsa injiniyo kugwedezeka mwachangu kwambiri. Ndi ndodo zazifupi zolumikizira, injini imatembenuza crankshaft kuchokera pakatikati mpaka pang'onopang'ono, zomwe zimapangitsa injiniyo kugwedezeka kwa nthawi yayitali.

Gawo 3 la 4: Kuyeza Mphamvu Zamagetsi Zamagetsi Pamagalimoto Amagetsi

Zipangizo zofunika kuti amalize ntchitoyi

• cholembera ndi pepala
• Buku la Mwini Magalimoto

Gawo 1: Pezani buku la eni ake agalimoto yanu. Pitani ku index ndikupeza makhalidwe a galimoto yamagetsi. Ngati mulibe bukhu la malangizo, pezani dzina la dzina pagalimoto yamagetsi ndikulemba mawonekedwe ake.

Khwerero 2: Lembani ma amplifiers omwe agwiritsidwa ntchito, magetsi ogwiritsidwa ntchito komanso mphamvu zotsimikizika. Kenako gwiritsani ntchito chilinganizo ((V * I * Eff)/746=HP) kuti mudziwe mphamvu yamahatchi. V = voteji, I = panopa kapena panopa, ndi Eff = mphamvu.

• Chitsanzo::
  
  

300 x 1000 x 0.80 = 240,000 746 / 321.715 = XNUMX

Galimoto yamagetsi idzatulutsa mphamvu zokwana 322 mosalekeza. Ma injini a dizilo ndi petulo sapitilira ndipo amafuna kuthamanga kosinthika.

Gawo 4 la 4: Ngati mukufuna thandizo

Ngati mukufuna thandizo lodziwa injini yagalimoto yanu kapena mukufuna thandizo lowerengera mphamvu zamahatchi a injini yanu, muyenera kupeza thandizo kuchokera kwa m'modzi wamakaniko athu ovomerezeka omwe angakuthandizeni ndi galimoto yanu. .
