<prompt> Yini engenzeka enjinini uma kunamasilinda amaningi? Njengoba kunikezwe umbuzo odlule, bhala umongo onempendulo yawo. Kungaba imisho engu-1 kuya kwengu-20. Umongo:  <response>: Indlela yokunciphisa ubukhulu balokhu kushisa nokupholisa yasungulwa ngo-1804 ngunjiniyela waseBrithani u-Arthur Woolf, owafaka ilungelo lobunikazi lenjini yakhe ye-Woolf ephezulu ngo-1805. Enjinini ye-compound, umusi ophakeme ovela kubhayela uyanda kusilinda ophakeme HP bese ungena kusilinda esisodwa noma eziningi ezilandelayo ezinengcindezi ephansi LP. Ukwanda okuphelele komphunga manje kwenzeka kuma-cylinder amaningi futhi njengoba ukwanda okuncane manje kwenzeka kusilinda ngasinye ukushisa okuncane kulahleka ngomphunga ngamunye. Lokhu kunciphisa izinga lokushisa nokupholisa kwesilinda, kwandise ukusebenza kahle kwenjini. Ngokubeka ukwanda kuma-cylinders amaningi, ukuhlukahluka kwe-torque kungancishiswa. Ukuze kutholakale umsebenzi ofanayo kusuka kumphunga onomfutho ophansi kudinga umthamo omkhulu wesilinda njengoba lomphunga uthatha umthamo omkhulu. Ngakho-ke, ukujula, futhi ngokuvamile ukushaywa, kukhuphuka kuma-cylinders anengcindezi ephansi okuholela kuma-cylinders amakhulu.
