Iyo SOHC (single overhead camshaft) injini haiwanzo kushandiswa mumhando dzakajairika dzekutamisa mafambiro pamusika, nekuti kumhanya kunowanzo shandiswa kwemidhudhudhu kwakakwira.

Chimiro cheSOHC chiri nyore kupfuura icho cheDOHC, asi kunyange iine camshaft imwe chete, inoda kuendeswa kune mavharuvhu mana kuburikidza nemaoko maviri evhavha rocker kudzora kuvhura nekuvhara mavharuvhu.

mukana:

Nekuda kwekuti pane camshaft imwe chete, iyo inofambiswa zvakananga negiya renguva, injini haina kukanganiswa nekupokana kwekutenderera kwecamshaft kana kukurumidza kunowedzera, uye inogona kupedzisa kubuda kweiyo yakaderera kasi chikamu nekukurumidza.Mutengo wekugadzirisa wakaderera, chimiro chiri nyore, uye mafuta anodhura zvakanyanya mumigwagwa inowanzoshandiswa yakaderera.

Zvakaipa:

Pakumhanya kwakanyanya, nekuda kweiyo elasticity yevhavha rocker ruoko, kune zvakawanda zvinodzokororana zvinogadzira inertia.Naizvozvo, iyo valve stroke control pakumhanya kwakanyanya inogona kushaya kugadzikana uye kurongeka, uye panogona kunge paine kumwe kusingakoshi kuzunguzika kana ruzha.

DOHC

Sezvinoreva zita, DOHC inowanzo dhiraivha maviri camshafts.Nekuti ari maviri camshafts, camshafts anogona kutenderera uye kudzvanya mavharuvhu zvakananga.Iko hakuna svikiro revhavha rocker ruoko, asi inoda nguva refu cheni kana mabhandi kutyaira.

Nekutaura kwemaitiro, kugadzikana uye kurongeka kwepamusoro kutenderera kufefetera kweinjini kuri nani, izvo zvinoita kuti iwedzere kushanda kweinjini.Nekuda kwekushaikwa kwezvishandiso zvakawandisa zvinodzokororwa uye kutapurirana midhiya, vibration control iri nani.Kushandiswa kwemakamera maviri akazvimiririra kunobvumira kushandiswa kwekamuri yekupisa yakaita V, uye kona yevhavha inogonawo kuve yakanyatsogadziriswa mukugadzira.Iyo spark plug inogona kuiswa pakati pekamuri yekupisa, ichiita imwe mupiro mukupisa kwakafanana.

Zvakaipa:

Nekuda kwekudiwa kwekutyaira makamera maviri, pachave nekurasikirwa kwetorque mune yakaderera-kumhanya mhanyisa renji yeinjini.Nekuda kwechimiro chayo chakaoma, kuchengetedza uye kugadzirisa mari uye matambudziko akakwira kupfuura ayo eSOHC.

Mumainjini makuru ekutamisa, injini zhinji dziri kushandisa DOHC nekuti chimiro chinogona kuita zvirinani kunaka kwekutyaira kweinjini huru dzekutamisa, uye kamwechete sitiroko simba rekuita kweinjini huru dzekutamisa zvakare yakasimba, uye chiyero chekurasikirwa kweyakaderera torsion ichava diki.

Kungofanana nemotokari, kana mota diki dzemumba dzine kudiki-diki dzakatamiswa dzakashongedzerwa neDOHC, zviri nani kudzvanya mari nekuvandudza mutengo-unoshanda pane kushandisa SOHC zvakatsiga kuvandudza ruzivo rwemushandisi.

Nekudaro, zvinofanirwa kusimbiswa kuti mota dzeDOHC hadzina rombo rakaderera torque, uye mota dzeSOHC hadzisi dzine yakasimba yakaderera torque.Izvo zvichiri zvinoenderana nekugadzirisa zvigadziriso zvezvimwe zvikamu zveinjini.Izvo zvimiro zviviri zvinongokanganisa kugona kweinjini uye hupfumi hwemafuta uye mhando pasi pemamwe mamiriro ekushanda.
