Automobilski motor, benzin ili dizel, koji biraju, usporednu analizu

Desetljećima "rat" je "rat" između dizelskih i benzinskih motora, kako bi opovrgnuo postojanje od kojih je besmisleno. Danas mnogi proizvođači automobila opremljuju iste modele i dizelskih i benzinskih elektrana, stoga nije moguće reći da je ista vrsta vrste motora poželjna. Budući da se mišljenja stručnjaka ne slažu, u ovom članku ćemo pogledati sve prednosti i nedostatke benzinskog i dizelskog motora, što će vam pomoći razumjeti koji je bolji odabrati.

Osim toga, jedinice za napajanje klasificiraju se na mjesto i broj cilindara, prema vrsti goriva, u smislu broja operacija motora, prema metodi formiranja smjese goriva i tako dalje. Međutim, dizelski i benzinski motori su najčešći.

Potrošnja goriva dizelskog i benzina, komparativna analiza

Specifična potrošnja goriva je pokazatelj učinkovitosti koja određuje koliko goriva konzumira motor sa snagom od 1 kW u jednom satu. Specifična potrošnja goriva je veća za benzinske motore. Za dizelske motore, to je 200-230 grama, za benzin - 265-305 grama.

Osim toga, dizel za ubrizgavanje goriva odmah se javlja u komoru za izgaranje, odnosno, njegovi gubici su minimalni. U benzinskim motorima, zrak se miješa s gorivom u usisnom razvodniku.

Okretni moment dizela i auto na benzin

Motori za benzin su nevoljni, a ne dizel, što rezultira manjim momentom. Ako trebate izvrsnu vuču i često prenosite velika opterećenja, bolje je dati sklonost dizel - ona ima znatno veći moment, koji se provodi u cijelosti zbog visokog stupnja kompresije potreban za samo-paljenje dizela gorivo.

Maksimalna snaga, koja ima veću

Iako benzinske elektrane imaju manji okretni moment, oni su u stanju proizvesti visoku snagu i odmotati na velike revolucije, zbog čega imaju izvrsnu dinamiku ubrzanja. Kombinirajući s njima za ovaj parametar može samo modernim dizelskim motorima s turbopunjavanjem.

Pouzdanost, komparativna analiza

Dizelski motor smatra se pouzdanijim od benzina, koji je posljedica posebnosti svog dizajna, što uključuje smanjenu temperaturu izgaranja, stabilnost goriva i rad na malim revolucijama. Međutim, neki motori se odlikuju relativno niskim životom - posebno se odnosi na vozila posljednjih godina oslobađanja, u kojima dizelski motori imaju veliku količinu elektroničke opreme i visok stupanj prisiljavanja. No, unatoč tome, klasične elektrane dokazuju izvrsnu trajnost dizelskih motora.

Popravak, gdje sve teže

Iako, uz pravilnu operaciju, dizelski motori nose manje benzina i više izdržljiviji, u praksi se često razbijaju. Osim toga, popravak dizelskog motora je skuplji, zbog složenosti dizajna i velikih troškova rezervnih dijelova. U pravilu, rezervni dijelovi za benzinske motore su mnogo manji, a specijalist koji će biti za ovaj posao, kako bi pronašli mnogo lakše.

Kupovna cijena, koja je skuplja i zašto

U dizelskim motorima, omjer kompresije je mnogo veći, tako da je glava bloka, radilice, šipke, blok cilindara, klipova i tako dalje doživljavaju veće opterećenja, što rezultira prikladnim mora biti ojačana. Zapravo, cijena dizelskih motora gube s analozima benzina.

Troškovi usluga, što je razlika

U Rusiji, u pravilu, problemi s dizelskim motorom nastaju zbog korištenja loša kvaliteta goriva. Ulje i filter moraju se vrlo često mijenjati. Također, problemi se mogu pojaviti tijekom popravka, jer je dizelski motor složen dizajn. Automobili na benzinu u manjoj mjeri reagiraju na kvalitetu goriva. Moć i promet motora je prilično visok, a rezervni dijelovi za popravak su pristupačniji.

Razdoblje održavanja

Za razliku od benzinskih motora, učestalost održavanja dizela znatno je manja. Dakle, zamjena motornog ulja i filter ulja u dizelu treba provesti svakih 7,5 tisuća kilometara kilometraže, u benzinskom motoru - svakih 10 tisuća kilometara.

Trajnost dizelskih i benzinskih automobila

Motor benzina radi na višim revolucijama od dizela. Radni raspon dizelske jedinice je obično ograničen na 5000-6000 o / min, kada se benzin vrti na 8000-9000 revolucija u minuti. Dizeli su više izdržljiviji, ali samo pod uvjetom pravilnog rada.

U pravilu, benzinski motori idu u remont samo tristo tisuća kilometara kada neki dizelski motori mogu proći bez ozbiljne intervencije već do milijun kilometara.

Kako pronaći dobar mehaničar za održavanje dizela

Kao što je već spomenuto, kao rezultat složenosti dizajna dizelske jedinice, pronalaženje dobrog autoslemera nije tako jednostavno. Kontaktirajte samo testirani auto-popravak shop do visoko kvalificiranih stručnjaka kako biste izbjegli probleme u budućnosti.

Zimsko gorivo dobre kvalitete, zašto je važno za dizel

U dizelskim jedinicama, sustav goriva je vrlo osjetljiv, pa je potrebno koristiti visoko kvalitetno gorivo. Ako se u sustavu padne gorivo s niskim kvalitetom, odmah se javlja u parafinskim kristalima, koji su začepljeni filtrima i cijevima za gorivo, kao rezultat toga što će vozilo udariti u pokretu.

Brzina dizela i benzina

Brzina manevriranja u automobilu s dizelskim motorom mnogo je veća od automobila s jedinicom za napajanje benzina. To se objašnjava činjenicom da je dizel iznad okretnog momenta i postiže se na niskim rev. Zahvaljujući tome, vozač nema nelagodu kada manevriraju u roadflu.

Zagrijavanje u hladnom vremenu, koji ima duže

Vjerojatno, svi znaju o problemima dizelske jedinice u hladno vrijeme. U dizelu, gorivo je samo-prijedlog pomoću grijanja zraka tijekom kompresije. Na temperaturi manje od trideset stupnjeva Celzija, zrak se ne može zagrijati do radne temperature kako bi se zapalio gorivo. Da biste zaobišli ovaj problem, toplinske svijeće se koriste u dizelle, koja se zagrijava komora za izgaranje prije početka željene temperature.

Uz benzinski motor zimi, to je isključeno. Gorivo je stabilno zapaljivo iz iskre, koji omogućuje jednostavan početak. Vozač bi trebao odabrati samo odgovarajuće motorno ulje i slijediti naknadu baterije.

Ispušna toksičnost, koja je lošija

Budući da su indikatori izgaranja goriva i učinkovitost dizelskog motora veća, ima manje štetnih ispušnih plinova nego u benzinu.
