ʻO ka hopena o ke anawaena nozzle, ke kaomi injection a me ka mahana ambient ma nā ʻano spray i ka mīkini diesel(mahele 4)

E like me ka hōʻike ʻana o ka pakuhi i ka lōʻihi o ke komo ʻana ma ke Kiʻi 9 a me ka Kiʻi 10 me ka hoʻohana ʻana i nā ambient like ʻole.

ʻO ka mahana no ka 0.12 mm a me 0.2 mm nozzle anawaena e hoʻonui mau ʻia me ka manawa i lawe ʻia a no ka mahana ʻaʻole hāʻawi ʻokoʻa ka lōʻihi o ke komo ʻana. ʻO kēia ma muli o ka laulā o waena o nā mahana ʻaʻole nui loa. Eia nō naʻe, hoʻololi ka puʻe i loko o ka lōʻihi o ke komo ʻana, kahi o 40 MPa, 70 MPa a me 140 MPa me ke kaomi ambient 1 MPa ma ke kaomi lewa. E like me ke kiʻekiʻe o ke kaomi injector, ʻoi aku ka lōʻihi o ke komo ʻana. ʻO kēia no ka mea ua pale ʻia ka ehu me ke kaomi ambient.

Hōʻike ka Kiʻi 11 a me 12 i nā pakuhi o ka lōʻihi o ka haʻihaʻi ʻana me 0.12 mm a me 0.2 mm anawaena nozzle. Loaʻa ka hopena fluctuation ma ka mahana 500 K, kahi i hoʻonui nui ʻia ai ke kaomi injection 140 MPa a me ke anawaena nozzle 0.2 mm mai ka 1 mm a hiki i ka 2.3 mm. ʻO kēia paha ma muli o ka haki ʻole ʻana o ka droplet a lōʻihi ka lōʻihi, kapa ʻia kēia ʻo ka pauku o ka ligament. Hoʻohālikelike i ka mahana 700 K ma 140 MPa a me 0.2 mm ka lōʻihi o ka haʻihaʻi e kahe mau ana me ka manawa. No laila, pili ka wela i ka wela ambient kiʻekiʻe i hoʻohana ʻia, ʻoi aku ka pōkole o ka wā haʻihaʻi ma ka ʻāpana kumu.

4. Ka hopena

Ua hōʻike ʻia kēia haʻawina i kahi kahe hoʻohālikelike o ka wahie e kahe ana i ka nozzle spray ma mua o ka puhi ʻana. ʻO ka haʻahaʻa haʻahaʻa o ke kaomi ʻana i loko o ke keʻena e hoʻopilikia i ka haki ʻana o ka wahie i nā kulu liʻiliʻi loa ma mua o ka hoʻomaka ʻana o ka puhi ʻana i ka wahie. ʻO ka hoʻololi ʻana i ka mahana i loko o ke keʻena e pili pū i ka lōʻihi o ke komo ʻana o ka spray. No nā mahana ambient kiʻekiʻe, ʻoi aku ka maʻalahi o ka wahie a puhi i ka wahie ponoʻī. Eia kekahi, pili pū ke anawaena o ka nozzle i ka lōʻihi o ka haʻihaʻi ʻana o ka nozzle spray e like me ka hoʻoikaika ʻia e ke kiʻekiʻe kiʻekiʻe o ke kaomi ʻana i kahi e pōkole ai ka lōʻihi haʻihaʻi.
