Sezvo chinhanho chechikamu chinopa kutarisisa kwakanaka kwekufambisa mota, kugona kwekushanda kwesimba remagetsi kunoenderana nebasa rekushandisa kwezvinhu zvaro zvese. Neichi chikonzero, iyo michina inoda nguva nenguva kugadziriswa. Chinhu chekutanga chaicho chakakodzera kutariswa ndeye sefa remafuta (kwete iro hombe, asi iro rinonatsa mafuta achienda kune inobatanidza mvura). Paavhareji, yega yega 30 km yekumhanya inoda kucheneswa kana kutsiviwa neimwe nyowani.

Kunyangwe iyi nzira (yekuchenesa) inogona kubatwa nechero mutyairi, mune dzimwe mota chinhu ichi chinonetsa kuwana. Kazhinji iyo inoiswa mumutsara weinjini lubrication system mune mukaha pakati pepombi yemafuta nevharuvhu yema solenoid. Usati wabvisa firita, tinokurudzira kuti utange watarisa mumirairo kuti inotaridzika sei. Pamusoro pekuchenesa chinhu, iwe unofanirwa kuona kuti mesh nemuviri hazvina kukuvara. Paunenge uchiita basa, zvakakosha kuti uchenjere, nekuti firita pachayo haina kusimba.

Kubatsira uye kuipa

Vazhinji vatyairi vane mubvunzo nezve mukana wekudzima iyo inoshanduka vharuvhu yenguva system. Ehezve, tenzi pachiteshi chebasa anogona kudzima shifter iri nyore, asi hapana anogona kunyorera mhinduro iyi, sezvo uchigona kuve zana muzana uine chokwadi chekuti mune ino mota ichave isina kugadzikana. Ikoko hakugone kuve nemubvunzo wevimbiso yekushandira kwesimba remagetsi panguva yekuenderera mberi kwekushanda pasina shifter yechikamu.

Nekudaro, zvakanakira iyo CVVT system inosanganisira zvinotevera zvinhu:

1. Inopa kuzadza kwakanyanyisa kwemasirinda mune chero nzira yekushandisa yeinjini yemoto yemukati;
2. Izvo zvakafanana zvinoshanda pakunyatsoshanda kweshe remoto wemafuta-musanganiswa uye kubviswa kwesimba remagetsi pakumhanya kwakasiyana uye mutoro weinjini;
3. Iko kusvibiswa kwemagasi ekudzimisa kwakaderedzwa, nekuti munzira dzakasiyana, iyo MTC inopisa zvachose;
4. Hupfumi hwemafuta hwakadzikama hunogona kucherechedzwa, zvichienderana nerudzi rweinjini, kunyangwe hazvo mavhoriyamu makuru eiyuniti;
5. Iyo mota inogara inogara iine simba, uye pakakwirira revs, kuwedzera kwesimba uye torque kunoonekwa.

Kunyangwe hazvo iyo CVVT sisitimu yakagadzirirwa kudzikamisa mashandiro emota pamitoro yakasiyana uye nekumhanya, haisi pasina zvakati wandei. Chekutanga, tichienzanisa neyemhando yepamusoro mota ine imwechete kana mbiri camshafts munguva, ino sisitimu yekuwedzera yezvikamu. Izvi zvinoreva kuti chimwe chikamu chinowedzerwa mumotokari, icho chinoda kutariswa kana uchigadzirisa zvifambiso uye imwezve nzvimbo inogona kuparara.

Kechipiri, kugadzirisa kana kutsiva kwechikamu shifter kunofanirwa kuitwa neunyanzvi anokwanisa. Chechitatu, kubva pakachinjika chikamu, nekuda kwemagetsi, ichipa kurongedza kwakanaka kwekushanda kwesimba remagetsi, mutengo wayo wakakwira. Uye mukupedzisa, tinokurudzira kutarisa vhidhiyo ipfupi pamusoro pekuti nei shifter yechikamu ichidikanwa mune mota yemazuva ano, uye kuti inoshanda sei:

Variable vharuvhu nguva yekushandisa uchishandisa muenzaniso weCVVT

Mibvunzo nemhinduro:

Chii chinonzi CVVT? Iyi igadziriro inoshandura nguva yevhavha (Continuous Variable Valve Timing). Inogadzirisa nguva yekuvhura yekupinza uye kupera mavharuvhu zvichienderana nekumhanya kwemotokari.

Chii chinonzi CVVT Coupling? Iyi ndiyo kiyi actuator yeiyo variable valve timing system. Inonziwo phase shifter. Inoshandura nguva yekuvhura valve.

Chii chinonzi Dual CVVT? Uku ndiko kugadziridzwa kweiyo variable valve timing system. Dual - kaviri. Izvi zvinoreva kuti zvikamu zviviri zvinoshandura zvakaiswa mubhanhire rakadaro renguva (imwe yekutora, imwe yevhavhavha).
