The nozulu bụ a mmanụ ụgbọala dispenser. Ọzọkwa ya ọrụ bụ ime ka ikuku-manu ngwakọta na ịgba ya n'ime engine combustion ụlọ.

Iji ghọta ebe na ụgbọala ndị nozulu, ọ dị mkpa ka ị mara ihe mmanụ ụgbọala usoro ya si arụ ọrụ.

Nozulu Central injection

Ebe na ụgbọala Central injection nozulu usoro (otu ọgwụ)? Ọ na-emi odude ke oriri anwụrụ (ma ọ bụ manifold site na nke mmanụ ụgbọala na-abịa site carburetor na engine cylinders) tupu trotul, chọrọ otu maka ukpụhọde ikuku ọkọnọ ka usoro).

Nke a mbụ ọgwụ usoro, iji dochie carburetor engines. Ọ nwere naanị otu nozulu na a 4-cylinder (nke mere na ọ na-akpọ "otu injection"). The nozulu sprays na mmanụ ụgbọala trotul na enriches ya na ikuku. Nke a ngwakọta na-ahụ nri n'ime oriri manifold na a na-ekesa na cylinders. The dum usoro a na-ekwu site dị iche iche sensọ.

Injectors ekesa ọgwụ

Ebe ahụ ụgbọ ala injectors ekesa ọgwụ? Nke a mgbagwoju usoro. Ọ nwere 4 nozzles onwem na solenoid valves. Ha na-na oriri tract nke cylinders, otu ọ bụla.

Nozulu edo mmanụ ụgbọala na oriri valvụ nke cylinder. The mmanụ ụgbọala na-vaporized na weere na ikuku (ya eruba osobo niile ahụ trotul). N'adịghị ka monoinjection ebe a mmanụ ụgbọala ngwakọta guzobere cylinders onwe ha.

Ọrụ nozzles na-achịkwa otu kọmputa akara unit. Na ọ na-egosi Lelee Engine egosi na dashboard na ihe omume nke malfunctions nke engine.

The nozzles kpọmkwem ọgwụ

kpọmkwem ọgwụ usoro - na "nwa" na ngwa na ụgbọala. Ebe n'ime ụgbọ ala e nwere jets nke usoro ihe a, dị nnọọ maa. Ha niile "ejirila nwayọọ nwayọọ malite" n'ime combustion ulo na-emi odude ke n'elu nke cylinder. N'ihi ya, mmanụ ụgbọala na-aga kpọmkwem n'ime combustion ulo na e na-ama weere na ikuku. N'oge ọrụ nke injector kwekọrọ na a plurality nke sensọ, ọmụma na-ọnọ akara unit.

Ọrụ injector n'ime usoro ihe ndị ọzọ mgbagwoju anya: mmanụ ọkụ injection mgbali bụ nke ukwu elu na n'ụzọ dị ịrịba ama-amụba ọsọ nke igwe na ala gbapụrụ ọsọ triggered sọrọ mmanụ ụgbọala ogwu ogbugba.

abụọ na ụdị agwakọta na pụtara na engine. N'ihi ya, nozzles nwere ike ejikwara abụọ ụdịdị:

• Stratified ọrụ na-adị mgbe ndị engine na-arụ ọrụ na ala ma na-ajụ gbapụrụ ọsọ (edo mmanụ ụgbọala injector na njedebe nke mkpakọ ọrịa strok).
• Homogeneous ngwakọta nke ikuku na mmanụ ụgbọala chọrọ na elu gbapụrụ ọsọ (dịrị gaba n'ime ebe injector na-arụ ọrụ na oriri strok n'out oge na ikuku ọkọnọ).

N'ọnọdụ abụọ e nwere ọkpụrụkpụ mmanụ ụgbọala ego na elu arụmọrụ.

gas nozzles

Cars nọkwasi bụghị naanị na mmanụ ụgbọala ma ọ bụ mmanụ dizel, kamakwa gas. A, gas echichi - a ọzọ akụrụngwa na ụgbọ ala, na-kpọmkwem site na emeputa. Ot mmanụ ụgbọala nozzles na-adịghị mere maka ndị dị otú ahụ a na ngwaọrụ. Ya mere, iji mezue gas cylinder na gia unit bụ nke nozzles nke na-n'ịnyịnya na engine.

Iji chọpụta ebe nọ n'ụgbọala jets nke gas ngwá, iji mepee enyeghachi ya okpukpu anọ. Ha na-anọchi anya ndị plastic ngọngọ nke nkebi anọ (odude n'ime onye ọ bụla injector) na thereto chịkọtara hoses. Nke a na-ewu na-n'ịnyịnya dị ka nso mgbe nozzles.

Iche gas injectors nke mmanụ ụgbọala:

• The obosara nke cross ngalaba nke gas na ugboro ọzọ dị ka ọ na-agabiga ibu ibu nke manu karịa mmanụ ụgbọala.
• The ukwuu eletriki na-eguzogide nke mmanụ ụgbọala injector ruru ka mkpa ruo a nta ego nke mmanụ ụgbọala.
