I know this question doesnt really apply to engine swaps, but I always like to learn as much as I can about anything I get involved in and am wondering what the origin of this engine family is. Anybody know?

Well from what I remember, the 6b was introduced into the automotive world in 1986 as Cummins secured a contract with Dodge as an automotive supplier. Just as the 4.3 chevy is a 350 with the front two cylinders gone, The 4b is the 6b with the front two holes gone.

Not any real history there but many manufacturers have used that formula to keep the same products as to not retool for a new motor series. IE use what you have, reconfigure the engine around exsisting parts

"The 6BTA5.9 L B5.9 was the first member of the "B" engine family (known for the one litre per cylinder design) to be used in a passenger vehicle. This engine and its counter part the 4BT3.9 suposedly started life in 1983/84 as an agricultural engine family, for use in Case agricultural equipment by a joint venture between Cummins Engine Corp.andCase called Consolidated Diesel Corp. The engine was originally designed by Cummins and Case Corporation for commercial truck applications as well. First mass production contract for the engine was in when it Appeared in the 1989 in Dodge Ram pickup trucks. The engine has been used in marine, agricultural, industrial commercial, conventional and passenger vehicle applications. It has proved to be one of the most widely used and versitile platforms for an engine ever produced."

Some history...

In the US the first production B engine plant was in Rocky Mount, NC (still producing) as a joint venture with Case as described above. Later the Walesborough, IN plant followed in the US to produce the Dodge engine (for several years they were produced in Rocky Mount). Today both plants are building well over a combined total of 1,000 engines a day (4B, 6B & 6C). Also, the engine is built in the UK & Brazil (possibly other locations in the world). Some of the newer 4b version QSB (electronic controlled) that are built in Brazil go in the Ford F150 truck and use an HX27 Holset wastegated turbo.

This forum is great because.. If Clessie was still alive today I believe he would be very proud of all of the conversions! Cummins is the only independent diesel engine manufacturer that remains in the US that is not currently owned by a truck/auto manufacturer in some form. There is a long tradition of conversions and it all started that Christmas day in 1929 when Clessie pulled up in a 1925 Packard that he converted and convinced Mr Miller to keep funding the business in Columbus Indiana.

I had heard or read that Ford was coming out with a 150 diesel for the U.S. I take it that it will be the 4bt.

I think the new ford diesel will come out of europe, from their Dagenham diesel plant in the UK.
Ford have been flat out developing automotive diesels with PSA (Peugeot and Citroen) for years now, their 2.7 V6, 3.6 V8 (landrover TDV6, TDV8) and smaller passenger car engines are all from that alliance.

No, the Cummins engines are used in Latin America. Ford was to put the 4.5L PSD (6/8 of the 6.0L PSD) in the F-150 but the ridiculous environmental laws going into effect in the US killed it.
