Cav fais fab - keeb kwm thiab cov tswv yim tswv yim

Nrog lub advent ntawm lub internal combustion engine ua ntej rau lo lus nug sawv manufacturers li yuav ua tau kom lub cav fais fab. Tus thawj xyaw tau tsim yog heev irrationally. Zoo tag nrho cov qhov chaw tau ua los ntawm steel hlau los yog, ua mechanisms ponderous, inert thiab luv luv-lived. Piv txwv li, nyob rau hauv nruab nrab-xyoo pua 20th tsheb cav ua 100 horsepower tiv kev txom nyem ze li ntawm ib nrab ib tug ton. Kev sib piv, ib tug zoo li hwj chim niaj hnub tsheb motor nyhav tshaj 150 kg.

Yuav kom ua tau li no, manufacturers feem ntau zoo cov neeg kho tshuab engine tivthaiv: tos cov ntaub ntawv, alloys, tsim thiab siv hauj innovation, uas siv cutting-edge metallurgy thiab Science News for KIDS. Piv txwv li, cov kev siv ntawm txhuas pistons yuav ua rau kom lub cav fais fab los ntawm ntau tshaj 20 feem pua los ntawm kev txo nws nyhav thiab tsis sib haum xeeb kev quab yuam. Nws yuav tsum tau muab sau tseg hais tias txhuas nyob hauv cov ntshiab daim ntawv nyob rau hauv lub tsheb yog tsis siv, thiab thov nws alloys nrog magnesium, pob zeb ntais, manganese thiab chromium.

Cov kev txhim kho rau cov roj thiab tiv cav tseb systems kuj tshuam zoo dua lub hwj chim ntawm lub cav. Carburetors nto hloov ntawm hom ntab, uas chiv tau ib leeg-chamber, ces tus multi-chamber. Thiab ces lub ntu ntawm kev txhaj tshuaj tshuab uas muaj tuaj ib tug ntev txoj kev los ntawm tus neeg kho tshuab monoinzhektorov rau multipoint niaj hnub direct txhaj tshuab.

Nrog txoj kev, zoo thiab tiv cav tseb system: los ntawm tej yam yooj yim siv hluav taws xob interrupter rau Microprocessors. Tsis muaj leej twg niaj hnub cav tsis yog tsis muaj hluav taws xob tswj systems uas coj mus rau hauv tus account tag nrho cov tsis txog lub lag luam ntawm lub cav - kub thiab ceev ntawm huab cua, lub tsheb ceev, throttle txoj hauj lwm, crankshaft, camshaft, lub tshuaj nyob tus yeees ntawm rav cua tsheb gases, thiab lwm yam Raws li ib tug tshwm sim, lub tshuab hluav taws xob cov ntaub ntawv ua system txiav txim seb tus pom npaum li cas ntawm cov roj yuav tsum tau nkag mus rau lub engine, thiab lub sij hawm ntawm ignition ntawm roj cua sib tov. Yog li ntawd nws yog tiav ntau npaum lag luam los ntawm cov roj av cav.

Ua lub hwj chim ntawm lub diesel cav yog feem ntau tiav los ntawm kev siv ntawm ib tug turbocharger, uas twj ib tug ntau dua volume ntawm huab cua mus rau hauv lub tog raj kheej los ntawm lub zog ntawm rav cua tsheb roj cua. Tsis tas li ntawd, los txhim kho cov roj combustion efficiency nyob rau hauv niaj hnub diesel xyaw siv system «Common Rail».

Muaj ntau ntau txoj kev mus yuam cov qhov tso zis hauv cov combustion engine. Tiam sis peb yuav tsum tsis txhob hnov qab hais tias cov kev pab nyob rau hauv engine tsim - nws tsis yog tsuas yog es nyuab thiab lub sij hawm-siv, tab sis kuj kim heev. Peb yuav tsum tau high-precision tshuab cov cuab yeej, tshwj xeeb alloys thiab cov ntaub ntawv. Obviously, tsis yog txhua txhua tsav tsheb yuav tsum tau siv rau speeding li cov lub cev muaj zog tus nqi piv rau ib tug ib nrab nqi ntawm lub tsheb.

Yuav ua li cas yuav ua tau rau lub engine lub hwj chim twb yeej ib txwm nyob rau ntawm ib qhov siab?

Ua ntej ntawm tag nrho cov, koj yuav tsum tau xyuas tias tag nrho cov Hoobkas nqis twb ib txwm. Roj, uas yog siv nyob rau hauv lub engine yuav tsum yoog kom viscosity thiab txuj ci tsim nyog.

Yuav kom txo tau cov losses nyob rau hauv cov huab cua kom tsawg yog pom zoo kom siv ib lub lim pes tsawg kuj - thiaj hu ua "kuv zoo tshaj plaws" - qhov zoo, muaj tam sim no ib tug lossis loj xaiv ntawm cov ntxaij lim dej. Lawv tej zaum yuav txawv nyob rau hauv daim ntawv no, luaj li cas, txoj kev fixation, cov pom zoo engine ntim. Vim lub fact tias cov lim manufacturers muaj adapters rau feem ntau engine hom, cov installation ntawm xws li ib tug lim tsis tau tseem ceeb rau siab thiab them tus nqi.

Nce lub cev muaj zog hwj chim kuj yog nyob rau hauv lub tso system upgrading. Khaws nyob rau hauv lub siab hais tias yog koj lub tsheb yog tsis yog ib tug lawm system, nws yog qhov zoo tshaj plaws tig mus rau cov kev pab cuam qhov chaw nres tsheb, uas paub txhij txhua nyob rau hauv tso systems.
