1.Introke Stroke
Tsala umoya omtsha kwisilinda yejenereyitha yedizili esetyenzisiweyo ukubonelela ngomoya ofunekayo kumvelisi wedizili.

2. Uxinzelelo lweStroke
Ukufakwa kunye nokukhutshwa kwezivalo zeseti yejenereyitha yedizili zivaliwe, ipiston inyuka inyuka, irhasi ekwisilinda icinezelwe ngokukhawuleza, uxinzelelo lomoya luyenyuka, kwaye ubushushu bunyuka ngaxeshanye. Xa ifikelela kubushushu be-diesel, idizili iya kutshisa ize ikhule yodwa.
Iziphumo:
ReYandisa ubushushu bomoya ukulungiselela ukutshaya kombane
Yenza iimeko zokwandiswa kwegesi ukwenza umsebenzi
Ubushushu obuzenzekelayo bokomisa idizili ngama-543 ~ 563K

3.Combustion Ukwandiswa Stroke
Ukufakwa kunye nokukhutshwa kwezivalo kuvaliwe, ipetroli kwisilinda iyatshiswa ngokukhawuleza kwaye yandiswa, kwaye uxinzelelo lwegesi lukhuphuka ngokukhawuleza, lutyhala ipiston ukuba ihambe ukusuka kwiziko elifileyo ukuya kwiziko elifileyo.
Uxinzelelo lokunyuka komyinge: umlinganiselo woxinzelelo lokutsha koxinzelelo lokucinezelwa kokuphela

4.Exhaust Stroke
Ivelufa yokukhupha ivula kwangoko kwaye ivale kade: Ukuxhathisa okungafunekiyo, okunje ngesipina, kwenza ivalve yokukhupha ivuleke kwangaphambili ukunciphisa ukonyusa umphunga wepiston, kwaye ipiston ikakhulu ixhomekeke kwi-inertia xa igqiba inkqubo yokukhupha.

Injini yedizili apho ipiston ithatha imivumbo emine ukugqibezela umjikelo osebenzayo ibizwa ngokuba yinjineli yedizili enezibetho ezine.
