Indlela yokukhetha ukugcwalisa injini kwiibrashi zokusika ipetroli

1. Ioyile yeenjini ezineestroko ezimbini

Injini ene-stroke ezimbini isebenzisa umxube wepetroli kunye neoyile yenjini njengepetroli. Ipetroli kunye neoyile yenjini kufuneka zidityaniswe ngokulinganayo ukuze ioyile yenjini ixutywe ngokulinganayo kwipetroli. Ukuba ioyile eninzi ingena kwisilinda ngexesha elithile, kuya kwenza kube nzima ukuba ipetroli ivuthe kwaye ibangele ukuba injini iyeke ukusebenza. Kwangaxeshanye, ioyile eninzi inokubangela ukuba iiplagi ze-spark kunye neeringi zepiston ziqokelele ikhabhoni; Xa ioyile incinci kakhulu, udonga lwesilinda alunakulunywa, nto leyo ebangela ukuguguleka okukhulu, okukhokelela "ekutsaleni kwesilinda" kwaye kubangele iingozi ezinkulu.

Umlinganiselo weoyile exutyiweyo yioyile yenjini ekhethekileyo ye-stroke ezimbini: ipetroli = 1:25. Ipetroli enomgangatho we-90 # okanye ngaphezulu iyacetyiswa, kwaye i-93 # iyacetyiswa. Kusetyenziswa ioyile yenjini ye-stroke ezimbini, kwaye ioyile yenjini ye-stroke ezine ayivumelekanga ngokungqongqo.

Kucetyiswa ukuba usebenzise ioyile yenjini ekhethekileyo enomlinganiselo we-1:40 kwiiyure zokuqala ezingama-30 zomatshini omtsha, uze usebenzise umlinganiselo oqhelekileyo we-1:25 emva kweeyure ezingama-30. Akuvumelekanga ukuba idlule kwi-1:25, kungenjalo uxinzelelo luncinci kakhulu kwaye lunokubangela ukuba umatshini utsale isilinda. Nceda ulandele ngokungqongqo i-oyile enikwe umatshini ukuze ukhuphe ioyile, kwaye ungayikhupheli ioyile ngokungacwangciswanga ngokweqikelelo. Ioyile exutyiweyo kufuneka ilungiswe kwaye isetyenziswe ngoko nangoko, kwaye akuvumelekanga ngokungqongqo ukusebenzisa ioyile exutyiweyo esele ilungisiwe ixesha elide.

2. Ioyile yeenjini ezine-stroke

Musa ukuqala itanki yeoyile ngaphandle kokongeza ioyile. Umsebenzi ophambili weoyile kukugcoba iindawo ezihambayo zenjini yepetroli, ukuzipholisa nokuzipholisa, ukuzicoca, nokuthintela ukugqwala. Umgangatho kunye nokusetyenziswa ngokuchanekileyo kweoyile yenjini akuchaphazeli kuphela ukusebenza kunye nobomi benkonzo yeenjini zepetroli, kodwa kukwachaphazela nobomi benkonzo yoomatshini. Ke ngoko, kufuneka kukhethwe amanqanaba afanelekileyo eoyile yenjini ngokusekelwe kubushushu obungqongileyo benjini yepetroli.

Kwiqondo lobushushu eliphantsi, ioyile yenjini kufuneka ibe nokutyibilika okuhle, kwaye kwiqondo lobushushu eliphezulu, kufuneka ibe ne-kinematic viscosity efanelekileyo, ebaluleke kakhulu kwiinjini zepetroli ezipholileyo ngomoya. Nangona kunjalo, ngenxa yobukhulu obuncinci benjini ye-four stroke ye-brush cutter kunye nomthamo omncinci wetanki yeoyile, kunye nesantya esiphezulu sokusebenza, ifuna iimfuno eziphezulu zeoyile. Akuvumelekanga ukusebenzisa ioyile ephantsi, kwaye kuyacetyiswa ukusebenzisa ioyile ekhethekileyo kwimishini yegadi.

Yongeza ioyile yenjini ye-4T efanelekileyo kwitanki yeoyile, ubeke umatshini ngokuthe tyaba, kwaye inqanaba leoyile kufuneka lifikelele kwizibuko lokuzalisa itanki yeoyile ngaphandle kokugcwala. Jonga inqanaba leoyile ngaphambi komsebenzi ngamnye ukuqinisekisa ukuthambisa kakuhle komatshini.

Ipetroli yenjini ye-four stroke yipetroli ecocekileyo, enomgangatho we-90 # okanye ngaphezulu. Kucetyiswa ukusebenzisa ipetroli ye-93 #. Ukugcwalisa iinjini ezishushu akuvumelekanga, kwaye ukutshaya akuvumelekanga ngokungqongqo ngexesha lokugcwalisa.

Ehlotyeni elishushu, ngenxa yamaqondo obushushu aphezulu kunye noxinzelelo lomoya oluphantsi, ukumelana komoya kuyenzeka, kwaye kuyimfuneko ukuqinisa ukusasazwa kobushushu benjini kunye nokukhusela imibhobho yeoyile.

Musa ukusebenzisa ipetroli ene-lead eyongezelelweyo njengeoyile yokucoca ukuthintela ityhefu ye-ethyl lead. Musa ukusebenzisa ipetroli ebigcinwe ixesha elide kwaye yonakele, kungenjalo iya kubangela ukubiliswa okukhulu kunye nokufakwa kwekhabhoni. Indawo yokutsha kwepetroli iphantsi kakhulu, iyatsha, iyaqhuma, kwaye ikulungele ukuvelisa umbane ongashukumiyo. Kufuneka isetyenziswe ngokuhambelana nemigaqo kwaye igcinwe ngokukhuselekileyo.
