Kugwiritsa ntchito pagalimoto unit - mavuto ambiri ndi momwe angathetsere

Injini ya N46B20 imatengedwa moyenerera ngati gawo lolephera. Ndi ntchito yoyenera, kukonza ndi kufufuza nthawi zonse, injini sizimayambitsa mavuto aakulu.

Komabe, pali zolephera zomwe zimagwirizanitsidwa ndi mtunda wautali kapena ntchito yachilengedwe ya node zamunthu. Ndikoyenera kudziwa kuti ndi ndani mwa iwo omwe amawoneka nthawi zambiri.

Injini imatha kudya mafuta ambiri

Vuto loyamba lomwe limapezeka nthawi zambiri ndikugwiritsa ntchito mafuta ambiri. Kawirikawiri chifukwa chake ndi kugwiritsa ntchito mankhwala otsika - osatchulidwa ndi BMW ngati mafuta ovomerezeka. Zisindikizo za tsinde zowonongeka, kenako mphete za pistoni. Izi zimawonekera kwambiri pakuthamanga kwa 50 km. km.

Zinthu zomwe zimayamba kuchucha pambuyo poyendetsa ma kilomita omwe atchulidwa zimaphatikizansopo chivundikiro cha valve kapena pampu yowonongeka. Zikatero, m`pofunika m`malo zigawo zikuluzikulu.

Kugwedezeka ndi phokoso kumachepetsa chitonthozo cha galimoto

Nthawi zambiri, kugwedezeka kumamvekanso mwamphamvu. Panthawi yomwe 2.0-lita ya XNUMX-lita imayamba kumveka kwambiri, ndi bwino kuganizira za kuyeretsedwa bwino kwa Vanos variable valve timing system.

Sikuti kugwedezeka kokha kumasokoneza magwiridwe antchito agalimoto. Injini imathanso kupanga phokoso kwambiri. Izi nthawi zambiri zimachitika chifukwa cha vuto la tensioner ya nthawi kapena chinthu ichi chikatambasulidwa. Vutoli limachitika pambuyo pa 100 km. km. Zigawo ziyenera kusinthidwa.

N46B20 injini yoyenera ikukonzekera

Njira yabwino yowonjezera mphamvu ya galimoto yanu ikhoza kukhala pulogalamu ya ECU. Dongosolo la mpweya wozizira komanso mpweya wotulutsa mpweya ungagwiritsidwenso ntchito kuwonjezera mphamvu. Chifukwa chake, injiniyo idzapanga pafupifupi 10 hp. mphamvu zambiri.

Yankho lachiwiri ndi zida zolimbikitsira - turbocharger. Izi zitha kukhala zabwino m'malo mwa firmware yomwe yatchulidwa kale. Kuyika kosankhidwa bwino kumawonjezera mphamvu ya injini ngakhale mpaka 200-230 hp. Phukusili likhoza kumangidwa mugawo loyambira loyendetsa.
