Ngesonto eledlule sishayele iToyota Yaris GRMN eSpain — ungabona izithombe-skrini lapha. Imodeli njengoba wazi, isebenzisa injini engu-1.8 litre enamandla nge-volumetric compressor. Bekuyizaba ezinhle kakhulu zokukhuluma ngalobu buchwepheshe kwenye indatshana ku-Autopédia yethu.
Ivolumu ye-Compressor?!
I-volumetric compressor iyingxenye yomshini eklanyelwe ukwandisa amandla. Ngokuphambene nalokho ongase ukucabange, kude kakhulu nokuba ubuchwepheshe besimanje. I-compressor yokuqala ye-volumetric yangaphambi kweMpi Yezwe II. Imiklamo yokuqala ihlehlela emuva ngasekupheleni kwawo-1890 futhi yafinyelela ezimotweni kuphela ngo-1921, nezicelo kuMercedes-Benz 6/20 PS kanye ne-10/35 PS.
Ngaphambi kwalokho, kwakuyilobu buchwepheshe obenze ukuba bakwazi ukwandisa amandla, ukuzimela kanye nomthamo wokuthwala wezindiza zamabhomu ezazisetshenziswa eMpini Yezwe II.
Umphumela wayo osebenzayo ufana ne-turbo: ukucindezela umoya ekamelweni elivuthayo ukuze kwandiswe inani le-oxygen nge-cm3 ngayinye. I-oxygen eyengeziwe isho ukuvutha okunamandla kakhulu, ngakho-ke amandla engeziwe.
Nakuba umphumela ongokoqobo ufana, indlela ezisebenza ngayo ngeke yehluke kakhulu… kusukela lapha lapho izinto ziqala khona ukuba nzima.
Ama-Compressors vs Turbos
Ngenkathi ama-turbos ecindezela umoya enjinini esebenzisa amagesi akhipha umoya - ngama-turbine amabili - ama-volumetric compressor aqhutshwa injini, ngebhande (noma i-pulley) "entshontsha" amandla enjini. Lokhu “kweba”, njengoba sizobona kamuva, kungenye “yezithende ze-Achilles” zalobu buchwepheshe… Kodwa ake siqale sithole izinzuzo.
Nakuba ukusetshenziswa kwama-compressor kuyivelakancane, iqiniso liwukuthi kunezinzuzo zalolu hlobo lwesixazululo.
ngaphezu kwempendulo ngokushesha okukhulu kune-turbo, eqala kusukela kuma-revs aphansi - njengoba kungekho kubambezeleka ngenxa yokuntuleka kwengcindezi kumagesi okukhipha umoya njengama-turbos - ukulethwa kwamandla nakho kuqondile kakhulu. Ngaphezu kwalokho, ama-compressor we-volumetric nawo athembeke kakhulu. Njengoba sazi, amanye ama-turbos, emibusweni ethile, afinyelela ku-240 000 rpm/min nangaphezulu kuka-900 ºC.
Bona kule vidiyo ukuthi i-volumetric compressor isebenza kanjani:
Kodwa akuzona zonke izinzuzo. Ama-compressors asebenzanga kahle , ikakhulukazi kuma-revs aphezulu, ngenxa yokuthi i-compressor idinga amandla emishini, idala inertia ku-motor. I-inertia ehumusheka ekunciphiseni ukusebenza kahle kwemishini. Ingabe siya emagugu? Endabeni, isibonelo, i-Mercedes-Benz SL55 AMG, lokhu kulahlekelwa kwamandla ngesivinini kulinganiselwa ukuthi kudlula i-100 hp yamandla.
Ezinye izibonelo zezimoto ezibone izinjini zazo zisebenzisa ama-volumetric compressor esikhundleni sama-turbos iMINI Cooper S (R53), iMercedes-Benz enegama elithi “Kompressor”, ezinye izinjini zeJaguar V8, izinjini ze-Audi ezingamaV6 TFSI (njengoba kwenzeka kwe video), kanye neToyota Yaris GRMN esanda kwethulwa esesiyihlolile, futhi ngalesi sixazululo esikwazi ukukhipha u-212 hp enjinini engu-1.8 litre. Impilo ende ku-compressor!
