Nzira yekuverenga simba

Simba rebhiza rinoonekwa nebasa rakaitwa nekufamba kwenguva. Iko kukosha kwayo kwebhiza rimwe chete i33,000 pounds per foot paminiti. Mune mamwe mazwi, kana iwe neimwe nzira wakakwanisa kusimudza 33,000,XNUMX mapaundi tsoka imwe panguva imwe chete, unenge uchishanda nekumhanya kwebhiza rimwe chete. Mumamiriro ezvinhu aya, ungadai wakapedza nguva yesimba rehupenyu rebhiza rimwe chete.

Musiyano uripo pakati pesimba uye torque yemotokari

Horsepower

Simba rebhiza rinozivikanwa nekumhanya uye rinoyerwa nepamusoro revolutions paminiti (RPM). Simba ndiro rinomanikidza mugadziri wemotokari kuona iyo yakanyanya tachometer kuita uye zvakare inosarudza mhando yematayi uye kuturika kuchashandiswa pamotokari. Horsepower inoisa miganhu pakukurumidza kweinjini inogona kufambisa mota panguva yekutyaira.

Torque

Torque inozivikanwa nechisimba uye inoyerwa yakaderera (grunt) uye inotemerwa pane yakaderera revolutions paminiti (RPM). Torque ndiyo inoita kuti mota ibve pakuzorora ichienda kuzere. Vagadziri vanosarudza kuti ndeupi rudzi rwekusiyanisa uye kutapurirana kwekushandisa zvichienderana ne torque. Horsepower inongomhanyisa kutapurirana; zvisinei, torque ndiyo inokonzera kuti magiya aite kusangana nesimba rakawanda.

Chikamu 1 che4: Kuyera injini yemotokari simba

Zvinhu zvinodiwa kuti basa racho ripere

• peni nepepa
• Bhuku reMuridzi weMotokari

Danho 1: Tora kukosha kwemota torque. Iwe unogona kuzvitarisa mushandisi yemanyorero indekisi uye bhuku richakuudza iyo torque tsika.

Nhanho yechipiri: Tarisa kumusoro kumhanya kweinjini mubhuku remuridzi.

Nhanho 3: Wedzera kukosha kwe torque nehuwandu hwekumhanya kwemota. Iwe uchashandisa fomula (RPM x T)/5252=HP uko RPM iri injini kumhanya, T iri torque, uye 5,252 iri radians pasekondi.

• Muenzaniso:: 2010 Chevrolet Camaro 5.7-liter inogadzira 528 ft-lbs torque pa2650 rpm. Chekutanga waizoverenga 2650 x 528. Unowana 1,399,200 1,399,200 5252. Tora 266 uye ugovane neXNUMX uye unowana horsepower. Iwe uchawana XNUMX horsepower.

Kana iwe usina bhuku uye uchida kuziva simba reinjini, unogona kutarisa kuti ndeipi injini iri mumotokari. Iwe unogona kutarisa injini uye kuona kuti ingani masilinda ine injini kubva kunhamba yeinjection uye spark plugs.

Zvadaro tarisa rudzi rweinjini yakaiswa pamotokari. Tarisa ndiro iri pamusuwo, chikwangwani chiri pamusuwo wemadziro emusuwo wemutyairi. Iri ndiro richaratidza gore rekugadzirwa kwemotokari, hunhu hwekutakura uye saizi yeinjini. Kana usina ndiro yegonhi, tarisa nhamba yemotokari iyoyo. Tora nhamba uye uparadze VIN. Paunenge uchinge uine iyo VIN kuparara, iwe unozoziva kuti saizi yeinjini.

Tora saizi yeinjini woiwedzera nenhamba yemasilinda. Wotora nhamba iyoyo woiwedzera nenhamba yemasilinda akapatsanurwa nehukuru wozowanza ne3 kumainjini akajairwa kana 4 kune torque package injini. Wobva wawedzera mhinduro nepi. Izvi zvinokupa iwe injini torque.

• Muenzaniso::
  
  

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

Torque ndeye 306 yeakajairika injini uye 408 ine torque package. Kuti uone simba, tora mota uye uone iyo rpm kukosha.

Otomatiki hutachiwana

• Kudzivirira: Usati watarisa, iva nechokwadi chokuti mabhureki anoshanda. Mota ichange yave mukukwira kuzere uye mabhureki asina kunaka achaita kuti mota ifambe.

Danho 1: Seta bhureki yekupaka uye tanga injini. Isa mabhureki ebasa munzira yese. Chinja chibatiso chekuchinja kune "drive" chinzvimbo uye dzvanya gasi pedal kweinenge 3-5 masekonzi pakuvhurika kwakavhurika throttle.

Nhanho 2: Pakazara throttle, tarisa iyo RPM sensor. Rekodha chiyero chekumanikidza kuverenga. Semuenzaniso, geji inogona kuratidza 2500 rpm. Iyi ndiyo yakanyanya kukosha iyo torque inoshandura inogona kuburitsa pane yakazara injini torque.

Chinyorwa Chekutumira

Danho 1: Tora motokari yekuedza kutyaira. Paunenge uchichinja, usashandise clutch, asi wedzera injini yekumhanya kusvika giya revha rabata.

** Danho 2: Kana iyo shift lever ichichinja kuita giya, tarisa iyo RPM sensor uye rekodha kuverenga.

Kana uchinge wava neRPM inoitirwa kuyedza zvitoro kana kuyedza kutsvedza, tora RPM uye x ye torque, wogovanisa ne5252 uye unowana simba rebhiza.

• Muenzaniso::
  
  

Stall speed 3350 rpm x 306 Standard injini specs = 1,025,100 5252 195/3350 = 408. Yeinjini ine torque package: Stall speed 1 rpm x 366 = 800 5252, 260/XNUMX = XNUMX

Nokudaro, injini inogona kuva nesimba re 195 hp. yeyakajairwa injini kit (3" gomba kudzika) kana 260 hp ye torque kit (4" gomba kudzika).

Chikamu 2 che4: Kuyera simba reinjini pane chinomira mota

Zvinhu zvinodiwa kuti basa racho ripere

• Breaker 1/2 drive
• Kudzika micrometer kana caliper
• Internal micrometer
• Micrometer set
• peni nepepa
• SAE/Metric socket set 1/2 drive
• Telescopic sensor

Kana iwe uine injini pane inomira injini uye uchida kuona kuti ingani simba rebhiza rinokwanisa kugadzira, unofanirwa kutevera matanho aya:

Danho 1: Bvisa manifold akawanda uye injini silinda misoro. Ita shuwa kuti une pani kuitira kuti inotonhorera kana mafuta ikangoerekana yadonha kubva pasi peinjini.

Danho rechipiri: Tora micrometer yemukati kana telescopic geji. Eresa dhayamita yecylinder kutenderedza kumusoro, pazasi pemukuru wering.

• Cherechedza: Ringi remhete ndipo panomira piston yoita rukova pamusoro pepiston sezvo pisitoni inorira mubore wear.

Danho rechitatu: Mushure mekuyera gomba, tora seti yemamicrometer uye tsvaga micrometer inokwana saizi yechishandiso chiri kushandiswa. Pima chishandiso kana kuverenga iyo mukati memicrometer kuti uone kukura kwegomba. Verenga micrometer uye rekodha kuyerwa. Semuyenzaniso, kutarisa bore pane 5.7 litre Chevrolet block ichaverenga nezve 3.506 pane micrometer.

Danho rechina: Tora yakadzika micrometer kana caliper uye tarisa chinhambwe kubva papiston inomira kumusoro uye pasi pegomba. Iwe unozofanirwa kuyera piston pazasi yakafa centre (BDC) uye zvakare kumusoro yakafa centre (TDC). Verenga kudzika geji kuverenga uye rekodha zviyero. Bvisa zviyero zviviri kuti uwane chinhambwe pakati pazvo.

Zvino zvawave nezviyero, unofanirwa kuuya neformula yekuona huwandu hwakakodzera hwebhiza rinozoburitswa neinjini.

Zvakanakisa kushandisa formula inotevera:

Silinda saizi inopeta kudzika kwecylinder kwakapetwa nhamba yemasirinda kanokwana pie chati.

• Muenzaniso::
  
  

3.506 x 3 x 8 x 3.14 = 264.21

Uyu muenzaniso unobva pane 5.7L Chevrolet injini ine bore ye3.506, yakadzika masendimita matatu, inokwana macylinders masere, uye yakapetwa ne (3), ichipa 8 hp.

Ikozvino, iyo yakareba piston sitiroko muinjini, iyo injini ine torque yakawanda, pamwe nekuwedzera simba rebhiza. Nematanda akareba ekubatanidza, injini inotenderera crankshaft nekukurumidza, zvichiita kuti injini imuke nekukasira. Nemapfudzi mapfupi ekubatanidza, injini inotenderedza crankshaft kubva pakadzikama kuenda kune zvishoma, zvichiita kuti injini idzoke kwenguva yakareba.

Chikamu 3 che4: Kuyera Magetsi Mota Simba reMagetsi Mota

Zvinhu zvinodiwa kuti basa racho ripere

• peni nepepa
• Bhuku reMuridzi weMotokari

Danho 1: Tsvaga bhuku remuridzi wemotokari yako. Enda kune index uye uwane maitiro emagetsi emagetsi. Kana iwe usina bhuku rekuraira, saka tsvaga zita rezita pamota yemagetsi uye nyora pasi maitiro.

Danho rechipiri: Nyora pasi amplifiers anoshandiswa, magetsi anoshandiswa uye kushanda kwakavimbiswa. Wobva washandisa fomula ((V * I * Eff)/746=HP) kuona mota yebhiza. V = voltage, I = ikozvino kana ikozvino, uye Eff = kushanda zvakanaka.

• Muenzaniso::
  
  

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

Iyo mota yemagetsi inoburitsa anenge mazana matatu nemakumi maviri nemaviri emabhiza nguva dzose. Diesel uye peturu injini hadzienderere mberi uye dzinoda spidhi dzakasiyana.

Chikamu chechina che4: Kana uchida rubatsiro

Kana iwe uchida rubatsiro rwekuona injini yemotokari yako kana uchida rubatsiro pakuverenga simba reinjini yako, unofanira kutsvaga rubatsiro kubva kune mumwe wemakanika edu ane certification anogona kukubatsira nemotokari yako. .
