I-Mazda L3 izinjini
Okuqukethwe
Imodeli ebizwa nge-L3 iyinjini enamasilinda amane eyakhiwe yakhiqizwa i-Mazda auto concerning. Izimoto zifakwe izinjini ezinjalo kusukela ngo-2001 kuya ku-2011.
I-L-class family of units iyinjini eshintshayo ephakathi nendawo ekwazi ukumumatha ukusuka ku-1,8 kuya ku-2,5 litres. Zonke izinjini zohlobo lukaphethiloli zifakelwe amabhlogo e-aluminium, wona ahambisana nama-cast iron liners. Izinketho zenjini ye-diesel zisebenzisa amabhulokhi ensimbi anamakhanda e-aluminium ebhulokhini.

Izinjini zakwaMazda L3 seziqokwe izikhathi ezintathu esicongweni se-Engine of the Year. Babephakathi kwamayunithi ayishumi ahamba phambili emhlabeni kusukela ngo-2006 kuya ku-2008. IMazda L3 ewuchungechunge yezinjini iphinde ikhiqizwe ngabakwaFord, abanalo lonke ilungelo lokwenza lokho. Le moto eMelika ibizwa ngeDuratec. Ngaphezu kwalokho, izici zobuchwepheshe zenjini ye-Mazda zisetshenziswa yi-Ford ekwenzeni izimoto ze-Eco Boost. Kuze kube muva nje, izinjini ze-L3 ezinevolumu engu-1,8 no-2,0 amalitha nazo zisetshenziselwa ukuhlomisa imodeli yemoto ye-Mazda MX-5. Ngokuyinhloko, izinjini zalolu hlelo zafakwa ku-Mazda 6 izimoto.
Lawa mayunithi amele ifomethi yezinjini ze-DISI, okusho ukuba khona komjovo oqondile nama-spark plug. Izinjini ziye zanda amandla, kanye nokugcinwa. Injini ye-L3 standard displacement engu-2,3 l, amandla aphezulu angu-122 kW (166 hp), i-torque engu-207 Nm/4000 min-1, okuvumela ukuthi uthole isivinini esiphezulu - 214 km / h. Lezi zinhlobo zamayunithi zifakwe ama-turbocharger abizwa nge-S-VT noma i-Sequential Valve Timing. Amagesi e-exhaust ashile ashayela i-turbocharger, equkethe ama-blade amabili, esenzweni. I-impeller iphothwa endlini ye-compressor ngosizo lwamagesi afinyelela ku-100 min.-1.
I-Dynamics yezinjini ze-L3
I-impeller shaft ijikelezisa i-vane yesibili, empompa umoya ku-compressor, ebese idlula egumbini elivuthayo. Njengoba umoya udlula ku-compressor, kushisa kakhulu. Ngokupholisa kwayo, kusetshenziswa ama-radiators akhethekile, umsebenzi wawo othuthukisa amandla enjini ukuya phezulu.
Ngaphezu kwalokho, injini ye-L3 iye yathuthukiswa ngokobuchwepheshe ngaphezu kwamanye amamodeli, yaba nokuthuthuka kukho kokubili ukwakheka kanye nezingxenye ezintsha zokusebenza. Ukulawulwa kwezigaba zokusatshalaliswa kwegesi sekuthole ifomethi entsha kulezi zinjini. I-block, kanye nekhanda le-cylinder, zenziwe nge-aluminium yezinjini.
Ngaphezu kwalokho, kwenziwa izinguquko zokuklama ukuze kuncishiswe amazinga omsindo nokudlidliza. Ukwenza lokhu, izinjini zazifakwe amabhulokhi amakhasethi okulinganisa namaketango athule kudrayivu yomshini wokusabalalisa igesi. Isiketi eside se-piston sasibekwe phezu kwesilinda block. Iphinde yalekelelwa yisigqoko sokuthwala esihlanganisiwe esiyinhloko. I-crankshaft pulley isebenza kuzo zonke izinjini ze-L3. Ifakwe i-torsional vibration damper, kanye nokumiswa kwe-pendulum.
I-axiliary drive belt contour yenziwe lula ukuze igcineke kangcono. Kubo bonke, sekuhlelwe ibhande elilodwa kuphela lokushayela. I-automatic tension ilungisa indawo yebhande. Ukugcinwa kwamayunithi kungenzeka ngembobo ekhethekile esembozweni sangaphambili senjini. Ngale ndlela, i-ratchet ingakhululwa, amaketanga angalungiswa futhi ingalo ecindezelayo ingalungiswa.
Amasilinda amane enjini ye-L3 atholakala emgqeni owodwa futhi avaliwe kusukela ngezansi nge-pallet ekhethekile eyenza i-crankcase. Lesi sakamuva singasebenza njengendawo yokugcina uwoyela wokugcoba nokupholisa, imininingwane ebalulekile yokwandisa ukumelana nokugqokwa kwenjini. Iyunithi ye-L3 iqukethe ama-valve ayishumi nesithupha, amane kusilinda esisodwa. Ngosizo lwama-camshaft amabili atholakala phezulu enjini, ama-valve aqala ukusebenza.
Izakhi zenjini nemisebenzi yazo
| I-actuator yokushintsha isikhathi se-valve | Ishintsha ngokuqhubekayo i-exhaust camshaft kanye nesikhathi se-crankshaft ekugcineni kwe-camshaft yokudonsa isebenzisa ingcindezi ye-hydraulic evela ku-valve yokulawula uwoyela (OCV) |
| I-valve yokulawula uwoyela | Ilawulwa isignali kagesi evela ku-PCM. Ishintsha iziteshi zikawoyela we-hydraulic we-variable valve actuator |
| Inzwa yesikhundla se-Crankshaft | Ithumela isignali yesivinini senjini ku-PCM |
| Inzwa yesimo seCamshaft | Inikeza isignali yokuhlonza isilinda ku-PCM |
| Vimba i-RSM | Ilawula i-valve yokulawula uwoyela (i-OCV) ukuze inikeze isikhathi esifanele sokuvula noma ukuvala ngokuvumelana nezimo zokusebenza kwenjini. |
Injini igcotshwa ngepompo likawoyela, elibekwe ekugcineni kwe-sump. Ukunikezwa kwamafutha kwenzeka ngemigudu, kanye nezimbobo eziholela uketshezi kumabheringi e-crankshaft. Ngakho amafutha ngokwawo afika ku-camshaft nakumasilinda. Ukunikezwa kwamafutha kwenziwa kusetshenziswa i-automation ye-elektroniki esebenza kahle, engadingi ukuseviswa.
Amafutha anconyelwe ukusetshenziswa:
- Isigaba se-API SJ ACBA A1 noma i-A3 ene-viscosity 52-30;
- Isigaba se-API SL ILSAC GF-3 esine-viscosity ye-5W-20;
- Amabanga e-API SG, SH, SJ, SL ILSAC GF-2, GF-3 nge-viscosity 40, 30, 20, 20W-20, 10W-30, 10W-40, 10W-50, 20W-40, 15W-40, 20W -50, 15W-50, 5W-20, 5W-30.
Ukushintsha kwe-L3-VDT
Injini iyi-four-cylinder, 16-valve enamandla angu-2,3 litres namakhamera amabili aphezulu. Ifakwe injini ene-turbocharged, lapho umjovo kaphethiloli wenziwa khona ngqo. Iyunithi ifakwe i-intercooler yomoya, i-ignition isebenzisa ikhoyili ekhandlelani, kanye ne-turbine yohlobo lwe-Warner-Hitachi K04. Injini inamandla angu-263 hp. kanye ne-torque engu-380 ku-5500 rpm. Isivinini esiphezulu senjini esingeke ilimaze izingxenye zayo singu-6700 rpm. Ukuze usebenzise injini, udinga uphethiloli wohlobo 98.
Ukubuyekeza kwamakhasimende
Sergey Vladimirovich, oneminyaka engu-31 ubudala, Mazda CX-7, L3-VDT injini: wathenga imoto entsha ngo-2008. Ngenelisekile ngenjini, ikhombisa imiphumela emihle kakhulu yokushayela. Uhambo lulula futhi lukhululekile. Okubi kuphela ukusetshenziswa kukaphethiloli okuphezulu.
U-Anton Dmitrievich, oneminyaka engu-37 ubudala, uMazda Antenza, 2-litre L3: injini yemoto yanele ukuze uthole okuningi ohambweni. Amandla asatshalaliswa ngokulinganayo kulo lonke uhla lwe-rev. Imoto yenza kahle kokubili emzileni nasekudluleni.
