How long has the 6bt engine design been around?

[Dennis Garrett]

I've been taking the TDR Register since 94, and have some back issues before that. Someplace in one of them, it says the engine was a joint development between Case-IH and Cummins, and the engine is manufactured in South Carolina (or North). At the time, only about 20% of the engines were configured for Dodge pickup application. The other 80% went into construction equipment, buses, RV's, boats, compressors, generators, tractors, cranes, large Ford & other brand trucks, & all kinds of stuff world wide. Even Komatsu uses them in small dozers. Hell, I get my oil filters at the Case-IH dealer!

Where's CMECHANIC when we need him? (Oppps!!)

4b/6b engines

I'm not sure if the 6b was offered without turbo, but you can still get 4b-3. 9 engines (as long as you are not an OEM), as we've installed them in 3010, 3020 John Deere, and older IH tractors.

It is an excellent thread!

I do remember reading a very early TDR, and the whole background on the B engine was outlined. I believe the Case story is the truest, but the idea of where the engine was really originally drawn, and by whom is quite intruiging. The B and C are not like other Cummins engines.

As far as Cat engines go, The only small engine I have dealt with is the 3116, and this uses a Power joke type HEUI system. The next larger Cats I have dealt with- 3208, 3304, 3306 all use a basic inline pump and injector sytem unique to Caterpillar.

According to the book "The Engine That Could" the "B" Engine was designed for the JI Case company. The prototype first ran early in 1983 and the first production engine came off the assembly line on July 1.



The idea was sprouted by Cummins desire to get into the "small diesel" market, the problem was the money it takes to start a wholly new design. So Cummins approached several other companies such as Perkins, Ford, GMC. They all turned down the idea so Case was approached and they wanted a diesel manufacture to build them engines because of the increased complexity of newer engines. So a joint venture between the two started it all.

Coming this fall

The new Cummins A series, made in Korea. 3 & 4 cylinders, 18 to 60 hp, 0. 9 - 2. 3L. Looks just like the B series on purpose. They figure initial sales at 600,000 units per year.

 

[Motorhead]

illflem, do they say what the A series is for? Sounds like they could be used in small car application.





Sorry illflem on the handle mis-spell... CR

 

[illflem]

Motorhead, they just say the A series is "targeted at a wide range of mobile and stationary applications, including construction, ag, utility and power generation. " They meet EPA emission standards, so a vehicle application is possible. Engine weights range from 254 lbs for the 18 hp to 441 lbs for the 60 hp.

4B's

recently looked at and drooled on new AGCO tractors. LT70 and LT85 have the electronic 4BT in them. carry the Cummins tag big as life. I WANT ONE!!!!!!

paychk,



You're right on the money!!!



I watched the Cummins/Case/CDC development from the start since I was in a closely related the business at the time. In fact, I was at the Cummins Engine plant in Columbus as a guest of Cummins at the time the announcement was made of the Dodge/Cummins engine partnership.

If I read this right then the original 6B engine design was initiated by Cummins. Cummins designed it, built it, and then sold it to Case. (And later to Dodge)

B series

The 780 case back hoe had a 4 cylinder engine in it, my father had one. At work we had a newer version of the 780 and the engine in it was b series cummins with a turbo charger, no innercooler, 24 volt starter and air brakes. The injection pump was not bosh ve or p7100. The reason for 24 volt is for the large pump that is ran off of the end of the crankshaft. It also has a air compressor on the frount the engine I have listened to some people whom say that the engine is not cummins but case engine, I didnot care who made the great engine only that it was made. I have seen the b engine also in a huge 4 wheel drive that is used to spray crops and the engine had a water inner cooler like the larger cummins.

We now have a 580 which has at cylinder cummins in. It is hard to beat cummins engines. Jimk

SOMEBODY SAY AMEN!

Other applications

I stopped to fuel at my regular place and a guy pulls thru with a trailer behind his rig. On the trailer was a 6bt but set up for natural gas. This thing had spark plugs and each valve cover had the individual ign coil mounted on it for that cyl. Didn't see a distributor. It was set up for a stationary water pump.

 

[HoleshotHolset]

I have seen a HUGE I-6 natural gas fired Cummins engine... . it was in a genset.



At first I thought it was a diesel... but when I saw the gas feed line... I had to take a closer look. What a sweet sounding engine... . then again, all the Cummins sound sweet!!

[nickleinonen]

does anyone know what they do to the compression ratio when they switch them to run on cng or lpg?



just curious...

 

[The patriot]

One of the contractors at work brought in a very large pressure washer. It had a 5. 9 cummins. I forget the exact number, but it was rated under 200 hp. Everything looked the same, but it didnt have a AFC housing.

Has anyone here received an "Official" response from Cummins about who the originators of the 6B design are?? (just curious)

 

[JHansen]

Gaseous fueled "diesel" engine CR

They drop it quite a bit Nick-depending on engine manufacturer, turbocharged or naturally aspirated, type of aftercooling (jacket water or air-to-air) etc. etc. etc..... seems to me the ones I've been able to find data out on range between 8:1 to 10:1.



Good to see I was pretty close to the answer of the B series origin. This may be the one thread in the last month that hasn't degenerated into backbiting yet! ...

Nada?

I have not recieved a response from Cummins yet. I think they forgot about me or the dweeb answering questions on the site knows nothing about engines.
