Yisiphi isayizi yenjini okufanele uyikhethe?

Kubalulekile ukuthatha isikhathi ukuze uyilungise khetha usayizi wenjini yesithuthuthu ngesikhathi sokuthenga.

Eqinisweni, lapho sithenga isithuthuthu, sivame ukubhekisa "kwabanamandla kakhulu", hhayi ukuthi sazi ukuthi sivumelaniswe nosayizi wethu, futhi ikakhulu uma ngabe zilungele izidingo zethu nokusetshenziswa kwethu, kunalokho esifuna ukukwenza. .

Ngakho-ke, ukukhetha isithuthuthu esifanele kwasekuqaleni kudinga ukukhetha injini. Futhi enye yezindlela ezibaluleke kakhulu okufanele zicatshangelwe ukuchema. Ngoba i-torque inquma amandla esithuthuthu.

Thola ukuthi yimuphi usayizi wenjini ongawukhetha.

Konke mayelana nosayizi wenjini yesithuthuthu

Injini yesithuthuthu ichazwa yizici ezintathu: ukufuduka, i-torque namandla.

Ingakanani injini yesithuthuthu?

Ukususwa kuwumkhiqizo wevolumu yesilinda ngenombolo yawo. Yiyo yokugcina equkethe i-piston edala ukuqhuma, okuvumela injini ukuthi iqale futhi isebenze.

Ngakho-ke, ukufuduka kungachazwa njengosayizi wenjini. Okubalulekile wukuthi uma isiba nkulu, injini inamandla. Kodwa ubani owathi amandla nawo asho ukusetshenziswa okuphezulu.

Ukuqonda Ukufuduka Kwenjini Yezithuthuthu

Uzoqonda ukuthi injini yesithuthuthu ingaba namasilinda amaningi. Yilokhu empeleni okunquma usayizi wokususwa okuphelele, okuvezwa ku-cm3. Kungakho ungathola izithuthuthu ezingama-50, 125, 250, 300, 450, 500, 600, kuze kufike ku-1000 emakethe.

Isibonelo, isithuthuthu esingu-125 sinokushintshwa okungu-125 cm3. Lokhu kuvamise ukuba yivolumu yesilinda. Ngakho-ke, lesi sithuthuthu sine-priori eyodwa kuphela isilinda. Ngokusekelwe kulesi sibalo, i-500 inokususwa okungu-500 cc kanye nesamba samasilinda angu-3.

Ungakhetha kanjani ukufuduka kwesithuthuthu esifanele?

Ukuze wenze ukukhetha okulungile, kubalulekile ukubheka imingcele ethile, njengolwazi lwakho lokugibela izithuthuthu, ukusetshenziswa ohlose ukukusebenzisa, kanye nesabelomali sikaphethiloli ofuna ukusibekela eceleni. Ezinye izimo zingathinta isikali, njengobude bakho, kuyilapho ukhumbula indlela yokukhipha.

Imibandela Yokucatshangelwa Lapho Ukhetha Ukususwa Kwenjini Yezithuthuthu

Umuzwa wakho womshayeli lesi umbandela wokuqala okufanele ucatshangelwe. Ngempela, kunconywa kakhulu ukuthi ungasigibeli isithuthuthu ngakho-ke uthenge isithuthuthu esinendawo enkulu yokufuduka uze ube nolwazi olwanele lokuluqonda kahle. Ngakho-ke, umthetho ulula: uma usaqala, khetha ukuqala isithuthuthu nge-injini encane yokuthutha.

Ukusetshenziswa kwesithuthuthu futhi kuyisici esibalulekile, ngoba ngenxa yezizathu zezomnotho kungcono ngaso sonke isikhathi ukusebenzisa isithuthuthu esinenjini efanelekile ukusetshenziswa kwayo. Uma uhlela kuphela ukusebenzisa amasondo akho amabili ekugijimeni kwedolobha ngezikhathi ezithile, asikho isidingo sokutshala ibhayisikili elinamandla, elihamba phambili. Ngoba ngeke isetshenziselwe ukusetshenziswa kuphela, kepha futhi ingadla uphethiloli omningi kunesidingo. Ngokufanayo, i-50 noma i-125 encane ngeke isebenze uma kufanele uthathe uhambo olude nsuku zonke. Kulezi zimo, kunconywa ukukhetha ukufuduka okukhulu.

Usayizi womshayeli kungathinta nokusebenza kwenjini ngakho-ke isithuthuthu. Ngakho-ke, kunconywa ukuthi unake le nqubo ukuze ukwazi ukusebenzisa ngokugcwele amakhono omshini. Ngokuvamile, lapho umgibeli emude, kulapho kudingeka khona amandla engeziwe ukuze asekele isisindo sakhe ngaphandle kokudela ukusebenza.

Umshuwalense wezithuthuthu nosayizi wenjini

Lapho ukhetha injini yesithuthuthu sakho, into esemqoka okufanele uyikhumbule ukuthi kufanele futhi ihlangabezane nenqubo ebekwe umshwalense wakho.

Isithuthuthu esibizwa ngokuthi "ivolumu enkulu" siyisilwane sangempela. Ayinamandla kuphela, kodwa futhi iyashesha kakhulu. Futhi umuntu othi "isivinini" ubuye asho ingozi enkulu yengozi. Futhi, ukuqagele, izinkampani zomshwalense azikuthandi ngempela. Yingakho ngokuvamile bebeka umkhawulo enanini lokunyakaza okuvunyelwe ukuze lowo onomshwalense athole ukwesekwa.

Ngamanye amazwi, qiniseka ukuthi usayizi wenjini okhethiwe wamukelwa inkampani yomshwalense obhalisa ngayo. Futhi thatha isikhashana ukuhlola ukuthi kukhona yini okungafakwanga kwewaranti mayelana nenani lamasilinda avunyelwe.

Futhi ekugcineni, uma ufuna ngempela ukukhetha isilwane esinevolumu engaphezu kuka-500 cm3, cabanga thatha umshwalense okhethekile wenjini enkulu... Lokhu kuzokuvikela kangcono, kepha qaphela ukuthi kungakubiza ngaphezu komshwalense ojwayelekile wezithuthuthu.
