Matoorka 1HZ
Tusmo
Matoorada Japan waxay mudan yihiin ixtiraam adduunka oo dhan. Gaar ahaan marka ay timaado unugyo naafto ah oo leh magaca HZ. Qaybtii ugu horaysay ee laydhkani waxa ay ahayd mishiinka 1HZ oo ah unug naafto ah oo wayn kaas oo noqday halyey horraantii 90meeyadii.
Taariikhda engine iyo sifooyinka
Qaybta korontada ee 1HZ waxa la sameeyay horraantii 90aadkii qarnigii hore gaar ahaan jiilka cusub ee Land Cruiser 80 SUVs. Baabuurta cutubkan ayaa la siiyay ku dhawaad dhammaan dalalka adduunka, sababtoo ah naqshadaynta injineernimada Toyota 1HZ ayaa suurtogalisay in lagu shaqeeyo mishiinkan xaalad kasta.
Tilmaamaha farsamada waxay ahaayeen kuwo dhexdhexaad ah:
| Mugga shaqada | 4.2 litir |
| Shidaalka | naaftada |
| Awooda qiimaha | 129 hooras at 3800 rpm |
| Tareenka | 285 Nm at 2200 rpm |
| Awoodda masaafada dhabta ah (khayraadka) | 1 kiiloomitir |
Bilawgii wax soo saarka, mishiinka naaftada ee 1HZ ma aha shirkaddu ku dhawaaqday in uu yahay unug koronto oo milyan oo doolar ah. Laakiin mar hore bartamihii 90-meeyadii waxaa caddaatay in hal milyan oo kilomitir ay ka fog tahay xadka hawlgalka mucjisadan injineernimada Japan.
Waddankeena waxaad weli ka heli kartaa SUV-yadii ugu horreeyay oo ay ku rakiban yihiin mishiinka gubashada gudaha ee 1HZ. Baabuurtan ayaa wax ka badan hal mar dib-u-dejiyey miiska masaafada ilaa maantadanna ma aha macaamiisha aad u badan ee adeegga baabuurka.
Faa'iidooyinka ugu waaweyn
Awoodaha ugu muhiimsan ee matoorku maaha sifooyin farsamo. Iyada oo mugga weyn, cutubku ma soo saaro fardo badan. Malaha, marawaxadaha ayaa saxi doona cilladaan, laakiin la socoshada awoodda unugga ayaa si weyn hoos loogu dhigi doonaa.
Anagoo dib u eegis ku samaynay darawalada baabuurta leh cutubka 1HZ, waxaan muujin karnaa faa'iidooyinka soo socda ee daanyeerka naaftada ee Toyota:
- awood masaafada weyn;
- dhaawac yar ma jiro;
- farsamaynta gabi ahaanba shidaal naafto ah;
- dulqaadka heerkulka shaqada ee aadka u daran;
- kooxda piston la isku halayn karo, oo ku xiran dayactir weyn iyo caajis.
Dabcan, isku halaynta iyo isku halaynta cutubku waxay ku xiran tahay shuruudaha iyo sifooyinka hawlgalkeeda. Haddii aad beddesho saliidda waqtigii loogu talagalay oo aad hagaajiso valve iyo nadiifinta dabka, dhibaatooyinka hawlgalka baabuurku ma soo baxayaan.
Dhibaatooyinka matoorka ee suurtogalka ah
Haddii hagaajinta waalka aan la sameynin waqtigii saxda ahaa, laakiin aad u daahday, xirashada piston ee kordhay ayaa laga yaabaa inay dhacdo. Sidoo kale, xallinta kooxda piston ayaa la arkaa marka la isticmaalayo ethers kala duwan si ay si dhakhso ah u bilaabaan mishiinka gubashada gudaha cimilada qabow.
Ha iloobin in tani ay tahay unug koronto oo duug ah. Waa inaad si taxadar leh u maamushaa. Sidoo kale dhibaatooyinka dayactirka caadiga ah waa kuwan soo socda:
- nidaamka bamka durista shidaalka ayaa ku dhibtoonaya ku dhawaad dhammaan matoorada u dhow 500 kun oo mayl;
- Cutubka waa in uu u adeegaa khabiir takhasus leh - tani waxay u baahan tahay rakibaad gaar ah oo ah calaamadaha dabka 1HZ;
- tayada shidaalka liidata ayaa si tartiib ah u burburisa kooxda piston iyo valves.
Waxaa laga yaabaa in mishiinkani aanu lahayn cillado kale. Mid ka mid ah faa'iidooyinka lahaanshaha baabuur leh cutubka korontadu waa inaad iibsan kartaa qandaraas 1HZ engine ah marka cutubka asalka ah uu daboolay in ka badan hal milyan oo kilomitir. Maanta, nidaamka noocan oo kale ah kuma kici doono lacag aad u badan, laakiin waxay ku siin doontaa baabuurka mashiinka cusub.
Soo koobid
Goobta laga isticmaalay matoorka 1HZ ayaa ahaa Land Cruiser 80, Land Cruiser 100 iyo Toyota Coaster Bus. Maanta, baabuurta leh cutubyada korontadu waxay sii wadaan in si firfircoon loo isticmaalo oo ha u ogolaanin milkiilayaashooda.
Waxay ahayd mid ka mid ah mishiinnada ugu wanaagsan ee shirkadda Toyota Corporation, taas oo qayb firfircoon ka qaadatay samaynta magaca shirkadda. Waxaa mahad iska leh hal-abuurradan oo kale in shirkadda maanta laga xushmeeyo adduunka oo dhan.
