Ja sam imao prilike da vozim jedno 2 dana bmw 320d,150ks, non stop zestoka voznja(ko kad je tudje ) i trosio je oko 10-12 litara

[TETAK]

Mercedesovi dizeli osim onih najmanjih troše sasvim normalno 8-10 litara.Ja sam uvek za benzin, dizel sam vozio samo u nuždi.....a bilo je...

[maki]

Mora da nisi vozio ovog 320d,nema razlike izmedju njega i nekog benzinca

[TETAK]

Iskren da budem brate nikad mi nije bilo jasno zašto BMW i Alfa uopšte prave auta sa dizel motorom.Tržište je čudo tako da i oni najtvrdji popuste.

[maki]

Pa da bi i mi obicni smrtnici mogli da osjetimo cari brze voznje

[TETAK]

Maki, Maki, 320D i nije baš dobar primer za tu tvrdnju....he,he,he

[maki]

Pa dobro vjerujem da je 330 xd bolje rijesenje ali i za to treba para

[TETAK]

Jeste bolje je......

[Lukas]

Nikad i baš nikad se neče moči dizel upoređivati u snazi sa benzinom nikad.

[Dora]

Seka je bila na stiklama...a ja u patikicama

Znam da je bilo davno ali dosada i eto....
Niko nije stigao do tako zanimljivih detalja kao što je obuća pored drugih zanimljivih detalja

Nikad i baš nikad se neče moči dizel upoređivati u snazi sa benzinom nikad.

Nemoj tako da si siguran, ne da moze da se poredi nego su vec jaci. Samo je pitanje aplikacije. Zasto?

Prvo, sta motor u stvari proizvodi? Ti kazes ne mogu se meriti po snazi. Pod snagom podrazumevas verovatno snagu u KS. Medjutim, motor ne proizvodi KS vec OBRTNI MOMENT. Sto se tice obrtnog momenta, dizel motori su bogami vec ispred benzinaca. Ono sto ti nazivas snagom, odnosno KS, je samo funkcija obrtnog momenta u odnosu na obrtaje, nista vise.

Evo, na primer, motor od mog X5 4.8is ima 4800 ccm, 360KS na 6500 rpm, i 500 NM na oko 4000.

BMW X5 3.0d ima 218KS ali mu je obrtni moment takodje 500nm ali na 2000rpm!

Sto u praksi znaci da poteze kao lokomotiva od vrlo malih obrtaja.

Prema tome, koliko god i ja voleo benzince vise nego dizele, dizeli lagano bivaju sve jaci i blizi benzincima po performansama...

[maki]

I dizel bi imao istu snagu u ks/kw ako ne i vecu na tih 6500 obrtaja, ali mu nedozvoljavaju velike rotirajuce mase,tj.na dizel motoru se koristi veci zamajac nego kod benzinca iz prostog razloga da umiri rad motora i smanji vibracije,klipovi su jaci jer moraju da izdrze veci pritisak kompresije koji je kod dizela duplo veci nego kod benzinca iz razloga sto veci pritisak u cilindru veca temperatura,a znamo da dizel radi na principu samozapaljenja smjese goriva i vazduha,znaci nema svjecice da uradi povelik dio posla vec je sve na klipu i karikama,da bi se pritisak dalje prenio trebaju jace klipnjace,lezajevi,radilica, sto sve skupa povecava tezinu,i sad kad bi se takav motor zaletio na 6500 obrtaja nema toga ko bi to sve zadrzao na okupu

Benzinci imaju vecu peak snagu jer sto vise rada (obrtaja) u jedinici vremena (min) to je veca snaga, kod dizela pritisak sagorijelih gasova u ekspanziji zamjenjuje broj obrtaja benzinca

Nadam se da sam bio jasan

[nole]

Doci ce i dizeli na malo vece brojeve u obrtajima. Nije to "nemoguca misija". Mozda bas do nekih 6.000 a preko malo teze

[maki]

Kod dizela se radi da se sa prenosom nadoknadi gubitak u obrtajima sto omogucava veliki obrtni moment,e sad vjerovatno izmisle neki materijal dovoljno cvrst a lagan i bolji sistem ubrizgavanja koji ce da smanji detonacije u motoru pa ce da bude bolje, proslo je vrijeme benzinaca po 5-6000ccm i kad je benzin bio malte ne ko voda, morace malo da privrnu slavinu

The World's Fastest Pickup Truck

Gale Banks Engineering (www.bankspower.com) didn't actually set out to build the world's fastest pickup truck. "The objective of the Sidewinder Project is to provide a positive showcase for diesel," says founder Gale Banks. "The whole idea of the Sidewinder Project is to illustrate that a diesel can be an extraordinary performance engine configuration. ... Further, I think we can get to the point that environmentalists think we've got something notable, because we're consuming less fuel and we're now clean and quiet."
Saturday was another perfect day on the salt. After reviewing the Sidewinder's on-board data acquisition information from Friday, tuning adjustments were made for additional qualifying runs. In this racing tune, the Cummins turbo-diesel was producing more than 1300 lb-ft of torque. On the first two qualifying runs on the 7-mile FIA course, Alexander went 216.034 mph and returned at 218.593 mph to improve the FIA and BNI International record to 217.314 mph. On the third qualifying run on the BNI National 5-mile course, the official timing clocks malfunctioned, although they did record an exit speed at the end of the course of 220.422 mph. The clocks did work properly on the fourth qualifying run, recording a measured mile at 217.212 mph and an exit speed of 222.139 mph!

5.
Nitrous Express is once again behind the World's Fastest Diesel. Driver Greg Hogue launched the Mopar sponsored truck to low nine second passes with a best time of 9.21 at 138 mph at Texas Motorplex on July 30, 2004. This was the lowest E.T. ever recorded with a diesel powered vehicle.

Opel Vectra OPC

This year´s Essen Motor-Show (November 28 to December 7, 2003) will host a spectacular world premiere. The Opel Performance Center (OPC) is presenting an ultra-sporty concept car based on the Vectra GTS. Featuring innovative twin-turbochargers, the 1.9-liter diesel produces 156 kW (212 hp) and peak torque of more than 400 Nm from as low as 1400 rpm. With this engine the Vectra OPC needs no more than 6.5 seconds to sprint from zero to 100 km/h. Top speed is limited electronically to 250 km/h, while fuel consumption in the European test cycle is only six liters per 100 kilometers. With this powerful yet economical, high-performance common-rail injection engine, Opel demonstrates again its renewed diesel expertise.
