Umahluko phakathi koomatshini bokucheba ingca abane-stroke kunye ne-two-stroke mowers

Umahluko phakathi kwe-four-strokeabachebi bengcakunye nezixhobo zokucheba ingca ezinemivimbo emibini

I-stroke ibhekisela kumakhonkco i-injini ehamba ngayo kumjikelo wokusebenza. I-four-stroke ithetha ukuba ihamba ngeekhonkco ezine. I-two-stroke ehambelanayo ihamba ngeekhonkco ezimbini. Umahluko omkhulu phakathi komtshini we-lawn-mower ezine kunye ne-stroke ezimbini kukuba isakhiwo se-injini ye-four-stroke sinzima ngakumbi, kwaye ukusebenza kwe-two-stroke kuphezulu phantsi kweemeko ezifanayo. I-injini ye-stroke ezimbini ilula ngobunzima, ineendleko eziphantsi zokuvelisa, kwaye inezinga eliphantsi lokungaphumeleli. Xa sithetha ngokuthelekisa, i-injini ye-four-stroke ayinangxolo encinci. Izinto eziluncedo zokucheba ingca ezine-stroke zisebenza ngokufanelekileyo, ukusebenza kakuhle, ukulondolozwa kwamanzi kunye nomhlaba, njl.njl. Makhe sijonge ulwazi olufanelekileyo olungezantsi.

Yintoni umatshini wokucheba ingca yepetroli enemivimbo emine?

Umatshini wokucheba ingca yepetroli enemivimbo emine ithetha ukuba yonke imijikelo emibini ye-injini yecrankshaft yomatshini wokucheba ingca, ihamba ngemivumbo emine yokuthatha, ukucinezela, amandla, kunye nokukhupha ukugqiba umjikelo wokusebenza, ngelixa umatshini wokucheba utyani onemivumbo emibini ehambelanayo kuphela. ifuna i-crankshaft ukujikeleza. Iveki enye kunye nemivimbo emibini inokugqiba umjikelo wokusebenza. I-4-stroke ihluke kwi-two-stroke ngokwemigaqo ye-powertrain.

Umahluko phakathi koomatshini bokucheba ingca abane-stroke kunye ne-two-stroke mowers

1. Ulwakhiwo

Ukusuka kwimbono yesakhiwo, isakhiwo se-injini yokucoca i-lawn-stroke ilula. Ikakhulu iqulunqwe yintloko ye-cylinder, i-cylinder, i-piston, i-piston ring kunye nezinye iindawo. Kukho imingxuma yokungenisa umoya, imingxuma yokukhupha umoya kunye nemingxuma yokuphefumla kumzimba wesilinda. ;Ukuvuleka kunye nokuvalwa komngxuma womoya kumiselwa yindawo yepiston. Xa kuthelekiswa ne-injini yomatshini wokucheba ingca ene-stroke ezine, akukho ndlela inzima yevalvu kunye nenkqubo yokuthambisa. Inkqubo yokupholisa ngokuqhelekileyo ipholile emoyeni, kwaye isakhiwo senziwe lula kakhulu.

2. Ukusebenza

Xa isantya se-crankshaft siyafana, inani lamaxesha i-injini yomatshini wokucheba ingca ene-stroke esebenza ngaxeshanye liphinda kabini elo le-injini ene-four-stroke. Ngokwethiyori, amandla e-injini ye-stroke ephindwe kabini kufuneka aphindwe kabini kune-injini ye-four-stroke (kodwa eneneni yi-1.5 kuphela ukuya ku-1.7 amaxesha). I-injini inamandla aphezulu ilitha nganye, amandla angcono, kunye nokungcangcazela kwe-injini encinci. Ukongeza, ii-injini ezine-stroke zikhaphukhaphu ngobunzima, zinexabiso eliphantsi ukwenziwa, zinezinga elisezantsi lokungaphumeleli, zikulungele ngakumbi ukuzigcina, kwaye zilungele kwaye zibhetyebhetye ukuzisebenzisa.

3. Izihlandlo zokufaka izicelo

Iinjini ezine-stroke zisetyenziswa kakhulu, kwaye uninzi lweemoto kunye noomatshini bokwakha baxhotyiswe ngeenjini ezine-stroke. Iinjini ezimbini ze-stroke zisetyenziswa ngokuqhelekileyo kwiimeko apho umlinganiselo we-thrust-to-weight ratio ubalulekile. Umzekelo, oomatshini bokucheba ingca, iisarha zamatsheyini, iinqwelo-moya eziyimodeli, oomatshini basefama, njl.njl. Ukuba uvuna izityalo ezithambileyo, kucetyiswa ukuba ukhethe umatshini wokucheba ingca ezine-stroke ukwenza isivuno sicoceke ngakumbi kwaye kube lula ukusisebenzisa.

4. Ingxolo

Nangona zombini ezi ndidi zomatshini wokucheba ingca zinengxolo noko, xa sithelekisa noko, oomatshini bokucheba ingca abane-stroke abangxoli kangako kunezomatshini zokucheba ingca ezinemivimbo emibini.

Izinto ezilungileyo zokucheba ingca yepetroli ezine-stroke

1. Ukusebenza okuphezulu

Ngokubanzi, umchebi wengca wepetroli onemivimbo emine unokusika ngaphezulu kwe-8×667 yeemitha zengca ngosuku, kwaye ukusebenza kwawo kulingana namaxesha ali-16 okuhlakula ngesandla.

2. Iinzuzo ezilungileyo

Ngenxa yesantya sokujikeleza ngokukhawuleza komtshini wengca, umphumo wokusika ukhula lwegadi yeziqhamo lulungile, ngakumbi umphumo wokusika ukhula ngokuthamba okuphezulu kungcono. Ngokuqhelekileyo, ukhula lwenziwa kathathu ngonyaka ukuze kuhlangatyezwane neemfuno zokulukhula.

3. Gcina amanzi nomhlaba

Ukuhlakula ngesandla ngegaba kuya kubangela umlinganiselo othile wamanzi kunye nokhukuliseko lomhlaba ngenxa yokuba umhlaba ongaphezulu uyatyekezwa xa ukhula. Ukukhuculula ukhula okwenziwa ngezandla kwiintsinjana zeleli kuya kubangela ukhukuliseko olukhulu lwamanzi kunye nokhukuliseko lomhlaba. Ukusetyenziswa kwemitshini yokucheba ukhula kunqumla kuphela iindawo ezingaphezulu komhlaba zokhula kwaye akunampembelelo phantse kumphezulu womhlaba. Ukongezelela, umphumo wokulungisa umhlaba weengcambu zengca uluncedo kakhulu ekugcineni amanzi kunye nomhlaba.

4. Yandisa ukuchuma

Xa usebenzisa umatshini wokucheba ukhula, linda de ukhula lukhule ukuya kumphakamo othile. Ukhula oluninzi olugawulweyo lunokugquma igadi yeziqhamo kwaye lunokusetyenziswa njengesichumiso esiphilayo kwigadi yeziqhamo ukwandisa ukuchuma komhlaba.
