Ukupholisa isekethe ekabili

Ezinjini zanamuhla, uhlelo lokupholisa lungafana nesistimu ye-brake, okungukuthi, ihlukaniswe yaba yiziyingi ezimbili.

Enye i-cylinder block cooling circuit kanti enye iyisekhethi yokupholisa ikhanda le-cylinder. Njengomphumela walokhu kuhlukana, ingxenye yoketshezi (approx. ingxenye eyodwa kwezintathu) igeleza emzimbeni weyunithi yamandla, bese enye igeleza ekhanda. Ukugeleza koketshezi kulawulwa ama-thermostat amabili. Omunye unesibopho sokugeleza koketshezi enjinini, omunye ngokugeleza ekhanda. Womabili ama-thermostat angafakwa endlini eyodwa noma ngokuhlukana.

Umgomo wokusebenza kwama-thermostats umi kanje. Kuze kufike ezingeni lokushisa elithile (isibonelo, 90 degrees Celsius), womabili ama-thermostat avaliwe ukuze injini ikwazi ukufudumala ngokushesha ngangokunokwenzeka. Kusukela ku-90 degrees kuya, isibonelo, ku-105 degrees Celsius, i-thermostat ebhekele ukudlula koketshezi ekhanda ivuliwe. Ngakho, izinga lokushisa lekhanda ligcinwa ku-90 degrees Celsius, kanti izinga lokushisa le-cylinder block ngalesi sikhathi lingaqhubeka nokukhuphuka. Ngaphezu kuka-105 degrees Celsius, womabili ama-thermostat avuliwe. Ngenxa yalokhu, izinga lokushisa le-warhead ligcinwa kuma-degrees angu-90, futhi izinga lokushisa lomkhumbi lingama-degree angu-105.

Ukupholisa okuhlukile kwekhanda le-cylinder kanye ne-cylinder block kunikeza izinzuzo ezithile. Ikhanda elipholile linciphisa ukungqongqoza, futhi izinga lokushisa eliphezulu lomzimba linciphisa ukulahlekelwa ukungqubuzana ngenxa yokukhuphuka kwezinga lokushisa likawoyela.
