Mazda MZR LF injini

Ma injini a LF class ndi mayunitsi amakono am'badwo watsopano wokhala ndi mphamvu komanso kukonzanso. chipangizo ali buku ntchito malita 1,8, mphamvu pazipita - 104 kW (141 HP), makokedwe pazipita - 181 Nm / 4100 min.^-1. Injini imakupatsani mwayi wopanga liwiro lalikulu la 208 km / h.

Makhalidwe amphamvu a injini ya Mazda LF mu chithunzi

Ma motors amatha kuwonjezeredwa ndi S-VT turbocharger - Sequential Valve Timing. The turbocharger ntchito pa mfundo ntchito pa mphamvu ya kuwotcha mpweya mpweya. Mapangidwe ake amaphatikizapo mawilo awiri a axial paddle, omwe amawomba mothandizidwa ndi mpweya wotentha wolowa m'gawo la thupi. Gudumu loyamba, likugwira ntchito, limazungulira pa liwiro la mphindi 100 ^-1. Mothandizidwa ndi shaft, gudumu lachiwiri la tsamba limakhalanso losapindika, lomwe limapopera mpweya mu compressor. Mpweya wotentha umalowa m'chipinda choyaka moto, kenako umakhazikika ndi radiator ya mpweya. Chifukwa cha njirazi, kuwonjezeka kwakukulu kwa mphamvu ya injini kumaperekedwa.

Mazda opangidwa ndi injini za mndandanda uwu kuyambira 2007 mpaka 2012, ndipo pa nthawi imeneyi anatha kusintha zambiri luso, mu kapangidwe wa unit ndi zinthu zake luso. Ma injini ena alandira njira zatsopano zogwiritsira ntchito magawo ogawa gasi. Mitundu yatsopanoyi inali ndi midadada ya aluminiyamu ya silinda. Izi zidachitidwa pofuna kuchepetsa kulemera kwa galimoto.

Ndemanga za ogwiritsa ntchito injini

Viktor Fedorovich, wazaka 57, Mazda 3, LF injini: adayendetsa Mazda yogwiritsidwa ntchito pamasewera. Galimotoyi yadutsa makilomita oposa 170. Ndinayenera kusintha makina operekera mafuta + kukonza chipika mu siteshoni yothandizira. Galimotoyo imatha kukonzedwa bwino. Kawirikawiri, ndimakhutira ndi chirichonse, chinthu chachikulu ndicho kugwiritsa ntchito mafuta abwino ndi mafuta okha.
