Po nekoj logici i 661-300 su trebale biti druga serija jer su opremljene sa dinamikim kocnicama...

Da ali imaju isti motor i perfomanse, samo nemaju mogucnost grejanja putnickih vozova.

Znam da je moguće, ali da je ona imala motor 645 ona bi bila druga serija.


Mozda ih nisu hteli pobrkati... :lol:

Ista kao i kod svake 661 za vuču 1342kW/1823KS, a ugradjena 1454kW/1975KS.

Hm... to je verovatno isti motor kao i na GP38, SD38 (ako je opremljena sa 645 motorom).

Zaboravili ste da se lokomotive 664 i 661 razlikuju osim po snazi dizel motora i po spoju vučnih motora te vučnim karakteristikama.
661 (G16) ima snagu dizelskog motora 1950 HP, maksimalnu vučnu silu 360 kN ili po starom 36000 kg i ima spojeve vučnih motora;
serija (dvije paralelne grupe sa po 3 vučna motora u seriji),
serija-paralela (3 paralene grupe sa po dva vučna motora u seriji)
dok lokomotiva 664 (G26C) ima snagu dizelskog motora 2200 HP
(osim slovenske) ima tri paralelene grane vučnih motora i maksimalnu vučnu silu 300 kN ili 30000 kg. Zato su to različite serije. Sve ostalo ne uvjetuje različitost serija već samo može uvjetovati različitost podserija.

Pozdrav Thehnika!

Da, dosta je velika razlika izmedju 661 i 664... Mi smo upredjivali 661 seriju "400" u odnosu na ostale 661... :wink:

661 i 661-400 se razlikuju pre svega u tome sto "Makedonka" nema nikakve mogucnosti grejanja u odnosu na obicne 661 i ako se ne varam ima neke izmene na Hasler brzinomeru.

Upravo tako Damire,nema grejanje(gde je bio generator pare,odsečen je gornji deo da bi bio bolji pregled iz kabine,tako da imaju zaista simpatičan dugačak"nos"tj.čelo lokomotive.
Za Hasler brzinomer nemam podataka(koji su naravno dobrodošli)kao i za još neke eventualne"modifikacije".

Snaga dinamičke kočnice,smeštene na čelo 661-300 lokomotive na mesto parnog generatora je ako se ne varam 1414 Kw.

Pa blizu si tacna snaga je 1425,6 kW,a ono na celima su otpornici elektrodinamicke kocnice,a iznad njih je ventilator za hladjenje istih.

Da za te"nabore"sa strane čela mi je jasno čemu služe.E,sad,podatak koji sam dao, našao sam u Železnicama,no,obzirom da je tvoj podatak"milimetarski"naveden,njega ću uvesti u knjigu gde držim sve Teh.-expl.Karakteristike v.vozila na ex JŽ koju sam rukom pisao za naše potrebe.Hvala na preciznom podatku :wink:

Ovo pise u zvanicnom uputstvu za rukovanje dizel-elektricnim lokomotivama 661 i 664 od Tomislava Kozulja.
Ta crna knjiga je za ljubitelje zeleznice pravo bogatstvo. :kul

Nesto se pomaknulo u EMD-u... :)

 

http://www.railwayga...locomotive.html

 

 

USA: The first of six pre-production Tier 4 compliant diesel locomotives being built by the Electro-Motive Diesel subsidiary of Progress Rail Services was unveiled at the Railway Interchange 2015 exhibition in Minneapolis on October 4.

On show at the outdoor display in BNSF’s Northtown Yard, the SD70ACe-T4 locomotive is powered by the new EMD 1010 engine, which has been designed to meet the tighter emissions requirements now in force without the use of a urea additive.

According to Progress Rail President & CEO Billy Ainsworth, ‘our goal has been to take the EMD locomotive product line to the next level in terms of innovation and sustainability’. Adding that the 1010 series engine has been developed through the combined engineering expertise of Progress Rail, Electro-Motive and Caterpillar, he said it offered optimised fuel efficiency as well as improved emissions performance.

As well as the 12-cylinder four-stroke engine, the SD70ACe-T4 includes a high performance AC traction system and radial bogies with individual axle control. It includes EMD’s latest traction control electronics and an enlarged cab offering better crew ergonomics and safety. EMD anticipates that the loco’s improved reliability and maintainability will offer better asset asset utilization  and lower maintenance costs.

Following extensive testing with the pre-production locos, Progress Rail expects to have its first series-built locomotives available for delivery to customers in the second half of 2016.

Video sa zvukom EMD SD70ACe-T4 sa novom generacijom četverotaktnih motora 1010

Nažalost još nisam našao zvok hladnog starta i zvuk ubrzavnja po stupnjevima.

Koliko znam, EMD je dosao do Tier 4, dalje ne...

Za sada samo brodski EMD 710 tier 4 motori:

Tier 4 Final For EMD Marine Two-Cycle
Posted on December 1, 2016
EMD710-0920829c.jpeg?ver=1480605912&aspe

Progress Rail announced that its EMD 710 Series Model E 23B Tier 4 marine engine has received U.S. Environmental Protection Agency (EPA) Tier 4 final certification, making it only two-cycle engine of its kind to achieve this distinction for the marine market. The announcement was made at the International Workboat Show in New Orleans, La.

“Our customers requested a U.S. EPA-certified solution to maintain our low lifecycle costs and we are pleased to deliver and receive this certification,” said Brian Grinter, Power Products director.”

The EMD 710 engine is available in 8-, 12, 16 and 20-cylinder configurations with ratings ranging from 200 to 5000 hp. The EMD 710 Series 12-cylinder marine engine has the same footprint as the previous product, which the company said addressed customers’ strict specifications to not increase the size of the vessel. The system incorporates Selective Catalytic Reduction (SCR) technology to produce fewer emissions while operating at the highest efficiency, Progress Rail said.

“Our teams have been working on lowering engine emissions for years, long before government standards were set,” said Chief Engineer Marti Lenz. “As a result, we have taken an integrated approach to creating products that ensure fewer emissions, while also improving fuel economy and engine performance. We’re proud of this accomplishment and thrilled to offer this option for our customers.”

The company said it anticipates delivering the first pair of engines to a customer by the end of the year. The certification also provides the company with the opportunity to bid for multiple ferry and tugboat projects, Progress Rail said.
