Kuyini amahhashi futhi kubalwa kanjani?

Amandla ezinjini zangaphakathi zomlilo abizwa ngokuthi "amandla wehhashi". Le pharamitha ikhona kuzo zombili izinhlelo zemethrikhi nezombuso, kepha azifani ncamashi. Ngokungajwayelekile, ukumakwa kwe-kilowatt (kW) kusetshenziselwa ukukhombisa le parameter, ngokwesibonelo, e-Australia.

Yini amandla wehhashi?

Amandla amahhashi ngempumelelo amandla wehhashi njalo. Le parameter ichazwa njengamandla adingekayo wokuphakamisa isisindo samakhilogremu angama-75 ngomzuzwana owodwa ukuphakama kwemitha elilodwa. Lolu hlelo lwamakhompiyutha lwalusetshenziswa ekuqaleni kwenguquko yezimboni, lapho amahhashi ayesasetshenziswa ukukhipha impahla ezimayini.

Inganekwane eyodwa ukuthi iyunithi yamandla wehhashi yasungulwa ngumqambi uJames Watt. Ukhombise ukuthi izinjini zakhe zomoya zisebenza kahle kangakanani (mangaki amahhashi iyunithi engangena esikhundleni).

Ifomula yokubala i-hp

Ngaphambi kokubala amandla we-motor, udinga ukunquma izinkomba ezimbalwa:

• I-Torque (iTrojan). Kukalwa nge-dynamometer ku-crankshaft.
• Izinguquko ngomzuzu (RPM). Kungalungiswa noma kudeshibhodi (ukufundwa kwe-tachometer), noma ngokuxhuma i-tachometer kagesi (uma imoto ingeyesizukulwane esidala).

Lezi zinkomba kumele zikalwe ngasikhathi sinye. Isibonelo, iyini i-torque ngo-6000 rpm. Ngemuva kwalokho sisebenzisa ifomula elandelayo: RPM * T / 5252 (lokhu kuyenzeka njalo). Umphumela uzoba amandla wangempela wenjini nge-rpm ethile.

Kuhlelo lombuso olusetshenziswa eGreat Britain, amandla wehhashi alinganiswa ngamayunithi we-horsepower yaseBrithani (hp). Amandla alinganiswa ne-brake-type dynamometer endaweni ethize njenge-crankshaft, shaft output shaft, axle yangemuva, noma amasondo.

Indlela elula yokuguqula ama-kilowatt abe amandla ehhashi ukuphindaphinda ngo-1,36. Kuthebula elingezansi, ungathola futhi isilinganiso samandla amahhashi (hp), ama-kilowatts (kW) namandla amahhashi ase-British (bhp).

Iyunithi:	bhp	kW	hp
bhp	1	0,745700	101,387
kW	134,102	1	135,962
hp	0,986320	0,735499	1

Imibuzo nezimpendulo:

Amandla amahhashi alithinta kanjani isivinini? Ukusheshisa imoto akuthintwa amandla amahhashi, kodwa inkomba torque. Uma i-torque itholakala ngobubanzi, kuba lula ukuthi imoto iqale futhi inyuse isivinini.

Kungani amandla enjini akalwa ngamandla ehhashi? Lapho kusungulwa izinjini zesitimu, amahhashi ayeyizinto eziyinhloko zokuthutha. Ukwenza kube lula ukuthi abantu bahlole ukusebenza kwamayunithi, baqhathaniswa nokusebenza kweqembu lamahhashi.

Amandla enjini alinganiswa kanjani? Uma imibhalo ibonisa amandla kilowatts, bese siphindaphinda lesi sibalo ngo-1.35962 - sithola inkomba yamahhashi. noma ngefomula: amandla = torque * crankshaft revolutions / 9549 (coefficient to convert to rpm).

Ihhashi linawo amandla angakanani? Ngokwemvelo, ihhashi elilodwa linamandla ehhashi elilodwa. Kodwa uma usebenzisa umthetho wokubala i-hp. (Amakhilogremu angu-75 ngomzuzwana owodwa akhuphuka aqonde nge-1 m), khona-ke ihhashi elilodwa lingakhula lifike ku-13 hp isikhathi esifushane.
